1 Overview

1.2 Introduction to the Router Command LineThe Cisco Internetwork Operating System (IOS) has several command modes.Each command mode provides a group of related commands.

For security purposes, the Cisco IOS software provides two levels of accessto commands:

One, allowing only basic commands, called USER EXEC mode

2 Cisco 2621 Installation


This case describes the Cisco 2600 router installation in the PSDN network(Cisco IP over X.25 solution).

3BK 17422 4052 RJZZA Ed.04 15 / 76


2.1 Install Router HardwarePI 01 contains the operations to be done in order to install and connect theCisco 2600 router. It gives a brief introduction to the router and describes howto connect the Ethernet Interface and serial cable.

2.1.1 Introduction

The router must be placed on a flat surface like a table within a range of sevenmeters from the host it will be connected to (A1353-RA or HMI). It is alsopossible to place it on a shelf. Make sure there is enough space left at both thefront and the rear of the router to prevent overheating.

The figure shows the Cisco 2600 backpanel.

Figure 1: Cisco 2600 Backpanel

The two ports, labeled Serial0 and Serial1 , are high-speed serial ports, witha Cisco proprietary interface with 60 connectors.

For the router on the remote (HMI / MFS / NMC) side, only the port Serial0 willbe used.

For the router on the Master Host side, both serial ports can be used.

The next connector, labeled Console , is the console port of the Cisco router.Before the initial configuration, the router can only be accessed via this port.

How to connect to the console port is described in Configure Router Software(Section 2.2).

The connector labeled aux is not used in this method, and therefore is notdocumented here.

16 / 76 3BK 17422 4052 RJZZA Ed.04


2.1.2 Connect Power

The router is designed for three-wire operation. This means groundconnection is mandatory .

The AC input voltage must be between 100 V and 240 V, the frequency50/60 Hz. These values are detected automatically by the router; no switchhas to be set.

To allow reliable routing service the router has to be connected to a mainspower circuit backed-up via a UPS.

1. Connect the router to the power supply.

Do not power on the router yet.

2. Update the Completion Check List (CCL).

2.1.3 Connect Ethernet Cable

To connect the router to the network, use a standard Ethernet cable with10BaseT connectors.

1. Connect the Cisco Ethernet card to the LAN network (usually to a hub).


2.1.4 Connect Smart Serial Module

1. To connect the router to the HMI / MFS one cable has to be used foreach link . This cable will be attached to one of the router’s serial ports(indicated in the figure as SERIAL 0 to SERIAL 1) and provides a X.21DCE interface at the other end.

2. To provide redundancy with PSDN, connect the two Cisco Smart Serial ports(SERIAL 0 and SERIAL 1) to PSDN.

Figure 2: 2–Port Smart Serial for WAN Interface Card

The Cisco reference for the above module is WIC-2T.

3. The Alcatel reference for the cables used for one link is:

Cable Cisco Smart Serial X.21 DCE: 1AF 01909 ABAA


3BK 17422 4052 RJZZA Ed.04 17 / 76


2.1.5 Connect Serial Cable

This cable assures the connection of the router to the PSDN network.

On the router remote side, the connector is an X.21 DTE male connector. Onthe other end, the connector type depends on the PSDN operator; it canbe an X.21 DCE connector.

1. Connect the Serial0 port to the PSDN network.


2.2 Configure Router SoftwarePI 02 explains how to configure the Cisco 2600 router software. After anintroduction to the router user interface, it describes how to perform the initialset up and configure the software. This includes how to customize the templatefile and download the edited file to the router.

2.2.1 Initial Setup

Initial Setup explains how to connect to the router before it is configured andhow to set its initial configuration.

2.2.1.1 Connect to the RouterWhen the router is not configured for IP connection (the initial configuration isnot yet done), the only way to connect to the router is by direct cable connection.

1. Connect the console port from the rear panel of the router to the serialport of a computer (laptop, PC or SUN machine), with the serial cable (thecable needs an RJ-45 connector on router side).

2. Use a terminal emulation program like Hyperterminal on a PC or tipon a SUN station to communicate with the router.The data transmissionparameters are:

9600 baud

8 data bits

No parity generated or checked

1 stop bit.

3. After connecting the cable, first switch on the terminal screen, then therouter. You must see the booting messages scrolling on your screen. If not,check the transmission settings.

2.2.1.2 Set Up Cisco 2621 Initial ConfigurationWhen booting the router for the first time, it starts automatically by runningthe set-up program.

If the router is not at its first configuration, the setup program does notstart automatically (the router goes directly into USER EXEC mode).

1. In this case, erase the existing configuration and restart the router withthe following commands:

(You must know the existing enable password ).Router> enablePassword: <enter enable password>Router# erase startErasing the nvram filesystem will remove all files!Continue ? [confirm] <Press Enter>[OK]Erase of nvram: completeRouter# reloadProceed with reload? [confirm] <Press Enter>

2. The setup starts automatically at the end of booting and displays thefollowing dialog:

The number of bits in subnet field is the number of ’1’ bits from the host partof the net mask (in binary format) of the router.The host part of the netmask is the last bytes of the netmask, depending onthe IP address class of the router:

For class A (0-127) the last 3 bytes of netmask

For class B (128-191) the last 2 bytes of netmask

For class C (192-223) the last byte of netmask.Refer to the SPS for the router netmask (or subnet mask).

3. To verify if the router is already operational at the IP level, list the IPinterfaces status and check the status of the FastEthernet0/0 interface:

Router> show ip int brief

The entry for the Ethernet interface must look like this:Interface IP-Address OK? Method Status ProtocolFastEthernet0/0 <ip_address> YES manual up up

Both Status and Protocol must be up .

After the IP configuration is set up, it is possible to connect to the router viatelnet , from any terminal within the local network of the router. To do this, avirtual terminal password has to be configured (this password was set as"cisco" ).


3BK 17422 4052 RJZZA Ed.04 21 / 76


2.2.2 Configure Software

The router configuration is done by downloading to the router a configurationfile prepared on a separate UNIX machine. This file is based on the Ciscotemplate configuration file supplied on a floppy disk (the UNIX machine musthave a floppy disk drive).

The file is customized according to the SPS and downloaded to router.

2.2.3 Customize Template File

The steps described assume that the UNIX machine is a SUN machine(workstation or server) running on the Solaris operating system. If youuse another type of machine or operating system, refer to the appropriatedocumentation for working with disks, editing text files and tftp server.

If the file is supplied on another media, use the specific commands for thatmedia to copy the file to the root’s directory of the UNIX machine.

Copy the Configuration

Template File

To copy the file from the floppy disk to the root directory / of the UNIX machine,do the following:

1. Insert the floppy disk in the floppy disk drive of the UNIX machine.

2. As root , enter the following command on the UNIX machine:# cd /# volcheck# cp /floppy/floppy0/cisco2600.zip /# unzip cisco2600.zip

3. Check if the configuration file has been decompressed.# ls /cisco2*.txt

The result of the command must be the configuration template file name:cisco2600.txt .

4. Eject the floppy disk.# eject floppy

Edit the File 1. Customize the file using vi or another text editor.

2. The file is presented below. Replace all necessary fields (marked here inbold) with the corresponding data from the SPS.

In the configuration file, all lines beginning with "! " are interpreted ascomments by the Cisco IOS and ignored.

2.2.4 Load the Template File to the Router

After the template file is customized and saved, download it from the UNIXmachine to the Cisco router as follows:

Common on Solaris

8 or 10

1. Check if the directory /tftpboot exists; if not, create it:# mkdir /tftpboot

2. Copy inside of this directory the configuration file.

For Cisco 3640 router# cp /cisco3640t1.txt /tftpboot


On Solaris 8 Only 3. Edit the file /etc/inetd.conf :# vi /etc/inetd.conf

4. Search for the line that defines the tftp server; it should begin with tftpor with #tftp .

If the line is uncommented (it begins with tftp ), go to Cisco Routersection.

If the line is commented (it begins with #tftp ), uncomment it by removing

the # sign. The line should be like this:tftp dgram udp wait root /usr/sbin/in.tftpdin.tftpd -s /tftpboot

5. Save the file, quit editing and perform the following operations.

6. Find the process id (pid ) for the inetd daemon:# ps -edf | grep inetd | grep -v grep

The pid is the number immediately after the user name (in this case, root ).For example, if the result of the above command was:

root 242 1 0 Sep 08 ? 0:00 /usr/sbin/inetd -s

The pid for the inetd daemon is identified as 242.

7. After you have identified the inetd pid , restart the daemon:# kill -HUP <pid>

On Solaris 10 Only 8. Enable TFTP service:# inetadm -e svc:/network/tftp/udp6# svcs | grep tftp

The following line must be displayed (as an example):online 10:12:33 svc:/network/tftp/udp6:default

26 / 76 3BK 17422 4052 RJZZA Ed.04


On the Cisco Router 1. Enter PRIVILEGED exec mode:Router> enablePassword: tmp_pwd

(The password will not be echoed to the display).

2. Using TFTP, copy the configuration file from a UNIX machine to runningmemory:

Router# copy tftp running

3. The following dialog appears (enter the answers indicated in bold below):Address or name of remote host[]?<remote_host_address>Source filename []? cisco2600.txtDestination filename [running_config]? <Press Enter>

Replace the string <remote_host_address> with the IP address of theUNIX machine where the configuration file was prepared and saved (e.g.192.10.10.192).

After downloading, the configuration file is automatically activated.

Check that there are no errors during the activation (i.e. syntax errors inthe configuration file). If there are errors, correct the file and again performthe initial configuration (section 2.2.1.2; do not forget to erase the existingconfiguration), then download the corrected file.

4. After the file is successfully downloaded and activated, save theconfiguration to the non-volatile memory:

<Router_name># write memory


2.2.5 Verify the Installation

1. List the status of available interfaces:<Router_name># show ip interface brief

Both Status and Protocol must be up for all used interfaces:

Ethernet interface (FastEthernet 0/0 )

Serial interfaces (Serial 0 , or Serial1 if the host is an A1353-RA Masterand the router has two X.25 links)

Point-to-point interface (Serial 0.1 , or Serial 1.1 if the host is anA1353-RA Master and the router has two X.25 links).

2. Display the IP routing table:<Router_name># show ip route

The two connected networks must be listed (the IP network on the MasterHost side and the IP network on the remote side).


3BK 17422 4052 RJZZA Ed.04 27 / 76


2.3 Configure HostsPI 03 describes how to configure the syslog server and the host (A1353-RAMaster Host or remote side).

2.3.1 Configure Syslog Service

For the Cisco router, the syslog service is used to record all system messages(i.e. interface down/up) to a separate UNIX machine, in order to keep arecord of them.

Usually only one host acts as a loghost (syslog server) within an operator’sIP network. The IP address of this host must have been given in the routerconfiguration profile (see previous section).

To make the syslog service available to the router, do the following on thesyslog server machine :

1. As root , add the following line at the end of the /etc/syslog.conf file :local7.debug ifdef(‘LOGHOST’, /var/log/syslog,@loghost)

Syslog is very sensitive to the syntax of the commands in this file. The separatorbetween local7.debug and ifdef(... text is at least one tab space .Also, there is one space after each command in the same line.

After this change is made, the syslog daemon has to be restarted.

2. First, find the process id (pid) for the syslog daemon:# ps -edf | grep syslogd | grep -v grep

The pid is the number immediately after the user name (in this case root ).For example, if the result of the above command was:

root 242 1 0 Sep 08 ? 0:00 /usr/sbin/syslogd

the pid for the syslogd daemon is 242.

3. After you have identified the syslogd pid , restart the daemon:# kill -HUP <pid>


2.3.2 Configure Host Database

On the local host machine where the router is directly connected (A1353-RA orHMI / MFS) on the syslog server (refer to the SPS to see if there is one):

1. Update the /etc/hosts file by adding a line containing the routers IPaddress, then its hostname:

<IP_address_of_the_router> <router_hostname>


28 / 76 3BK 17422 4052 RJZZA Ed.04


2.3.3 Configure Routing Entries

To reach non-local LANs from the host, a default routing gateway has tobe introduced.

2.3.3.1 Configure OMC-R, HMI and NMC

Apply this procedure to the A1353-RA Master Host, HMI and NMC (if it exists).

Edit the end of the /etc/rc2.d/S69inet file on the local host (on the A1353-RAMaster Host and all remote hosts) to see the remote IP network.

1. As root , add the following lines in the /etc/rc2.d/S69inet file :# Add the remote IP network/usr/sbin/route add net <remote_ip_network><local_router>

where the first line is a comment line and the second line is a new entry inthe routing table.

The gateway routing takes effect after a reboot.

2. To avoid a reboot of the machine, enter the following command as root (onthe A1353-RA Master host and all remote hosts) :

# route add net <remote_ip_network> <local_router>

where <remote_ip_network> is the remote network and <local_router>

is the IP address of the local router.

An example (for each side) is given below:

HMI / NMC Side # route add net 172.25.0.0 192.10.10.1

where:

172.25.0.0 is the IP address of the A1353-RA Master Host remote network

192.10.10.1 is the IP address of the router present on local HMI / NMC side.

A1353-RA Master Host

Side

# route add net 192.10.10.0 172.25.129.6

where:

192.10.10.0 is the IP address of the HMI remote network

172.25.129.6 is the IP address of the router present on the local A1353-RAMaster Host side.


3BK 17422 4052 RJZZA Ed.04 29 / 76


2.3.3.2 Configure MFS

Perform the following tasks on BOTH the active and passive station of the MFS.

1. Launch the following command for the MFS to reach the A1353-RA MasterHost network:

# route add -net <remote_ip_network><local_router_ip_address>

where:

<remote_ip_network> is the network part of the A1353-RA Master Host

<local_router_ip_address> is the IP address of the router from

the MFS side.

2. Add this route to the /etc/routes file so it will be available in the future(after a reboot) using vi:

vi /etc/routes

3. Add the following line at the end of the file:-net <remote_ip_network> <local_router_ip_address>

Example:-net 172.25 192.10.10.1

where:

172.25 is the network part of the A1353-RA Master Host remote side

192.10.10.1 is the IP address of the router present on the local MFS side.

4. Save the file and exit.


30 / 76 3BK 17422 4052 RJZZA Ed.04


2.4 Declare Remote HostsPI 04 explains how to declare the remote host(s), connected via the PSDN, tothe A1353-RA Master Host.

The remote host covers existing HMI, MFS or NMC machines.

Perform this PI on the Master host side.

2.4.1 Verify the Connection

Perform the following stepts to verify the connection:

1. Ping the remote router and the remote station. All must be alive , that is,the success rate must have a non-zero value:

Router# ping <host_ip_address>

where <host_ip_address> is the IP address of the host you want to ping.


2.4.2 Declare Remote HMI / NMC

1. Declare the remote HMI or NMC (if it exists) using the B9 A1353-RAAdministration Handbook, ’Day-To-Day Administration Tasks’ chapter.

2. Check that the declaration finishes correctly (in the Admin Facilities (OSM)window from A1353-RA iconbox).


2.4.3 Declare Remote MFS

1. Declare the remote MFS (if it exists) using the B9 A1353-RA MethodsHandbook, ’Declare MFS’.

2. Check that the declaration finishes correctly (in the DCN window fromA1353-RA iconbox).

3.3 Configure Router SoftwarePI 02 explains how to configure the Cisco 2811 router software. After anintroduction to the router user interface, it describes how to perform the initialset up and configure the software. This includes how to customize the templatefile and download the edited file to the router.

3.3.1 Initial Setup


3.3.1.1 Connect to the RouterWhen the router is not configured for IP connection (the initial configuration isnot yet done), the only way to connect to the router is by direct cable connection.

1. Connect the console port from the front panel of the router to the serialport of a computer (laptop, PC or SUN machine), with the serial cable (thecable needs an RJ-45 connector on router side).

2. Use a terminal emulation program like Hyperterminal on a PC or tipon a SUN station to communicate with the router.The data transmissionparameters are:

9600 baud

8 data bits


2 stop bits.

3. After connecting the cable, first switch on the terminal, then the router. Youmust see the booting messages scrolling on your screen. If not, checkthe transmission settings.

4 Cisco 3640/3725 Installation


This case describes the Cisco 3640/3725 router installation for BSC G2connections via MSC.

3BK 17422 4052 RJZZA Ed.04 43 / 76


4.1 Presentation

For the connections BSC-OMC without having a router , the X.25 channel

is connected from the BSC’s CPRA OSI board to an X.25 network (usually aPSDN) and then to the OMC. This is an expensive solution and also the

reliability depends on the PSDN provider.

With a Cisco router , the X.25 data is sent over the A interface betweenBSC and MSC. From MSC, each BSC X.25 channel is allocated to a 64

KB time slot on the MSC-Cisco link, using the MSC feature to route timeslots from one PCM to another.

The router is configured to sort out the X.25 channels from the PCM link and

to turn them into a single X.25 message stream toward the OMC-R, via aserial cable. This solution is less expensive because it uses the existing

PCM link between the BSC and MSC.

Also, to ensure a reliable link, redundancy can be provided on both BSCand OMC-R sides:

BSC side: on the link between the BSC and the MSC can be two time

slots on two different PCM’s . Then the MSC routes the time slotscoming from the BSC to the PCM link between the MSC and the router.

OMC side: there are two separate X.25 connections between the OMC-R(2 HSI ports) and the Cisco router.

This document describes the complete initial installation procedure of the a

CISCO 3600/3700 series router. It does not concern the upgrade froman existing routing configuration to a CISCO routing solution. However,

the method describes the connection of new OMC to new BSC’s (firsttime connection).

The Cisco 3600 series includes 3 types of routers: 3620, 3640 and

3660, depending on the number of network modules the chassis canaccommodate: 2, 4 and respectively 6 modules.

The Cisco 3700 series includes 2 types of router: 3725 and 3745, depending

on the number of network modules the chassis can accommodate: 2 andrespectively 4 modules.

The solutions chosen for OMC-BSS routing are given below:

Cisco 3640 router (with 3 network modules used, from 4 available)

4-port Ethernet module.

4-port Serial module.

1-port PCM module.

Cisco 3725 router (with 2 network modules)

4-port Serial module OR 2x 2–port Smart Serial module.

1-port PCM module.

4.2 Connect Router Hardware

4.2.1 Connect Ethernet Module

The Ethernet Network Module of the router provides four Ethernet interfaceswhich are able to handle 10BaseT. Port 0 also handles AUI (see the figurebelow).

1. Connect the router to the network with a standard Ethernet cable with10BaseT connectors.

2. Connect Port 0 of the Cisco Ethernet module to the Ethernet network(usually a hub or switch).

Figure 5: Four-Port Ethernet Network Module


4.2.2 Connect E1/T1 ISDN Network Module

Note: This module is a new one used to implement the PCM link.

This is a E1/T1 ISDN PRI network module used for E1 interface.

This Cisco module has a RJ-48C connector.

4.2.4 Connect Smart Serial Cable

This section is applicable only for Cisco 3725 router.

1. To connect the router to the OMC-R host via HSI interface, two cableshave to be used for each link . The first cable will be attached to one ofthe router’s serial ports (indicated in the figure as SERIAL 0 to SERIAL1) and provides a X.21 DCE interface at the other end. From this point,a second cable is used to connect this interface to one of the HSI portslocated on the HSI board.

2. To provide redundancy between the OMC-R and the router, connect twoCisco serial ports (SERIAL 0 and SERIAL 1) at two OMC-R HSI ports (theOMC-R must have at least two free ports on the HSI board).

Figure 8: 2–Port Smart Serial for WAN Interface Card

The Cisco reference for the above module is WIC-2T.

3. The Alcatel reference for the cables used for one link are:

Cable Cisco Smart Serial X.21 DCE: 1AF 01909 ABAA

4.2.5 Connect Serial Cable

1. To connect the router to the OMC-R host via HSI interface, two cables haveto be used for each link . The first cable is attached to one of the router’sserial ports (indicated in the figure as SERIAL 0 to SERIAL 3) and providesan X.21 DCE interface at the other end. The second cable is used toconnect this interface to one of the HSI ports located on the HSI board.

2. To provide redundancy between the OMC-R and the router, connect twoCisco serial ports (SERIAL 0 and SERIAL 1) to two OMC-R HSI ports (theOMC-R must have at least two free ports on the HSI board).

4.2.6 Connect PCM Cable

Check that the module is according to the PCM impedance on site (75 or120 Ohms).

The E1 interface provides up to 31 virtual channels. Each virtual channel

can be configured individually as a serial interface.

The E1 module provides a controller for transmitting and receiving data

bidirectionally at the E1 rate of 2.048 Mbps.

To connect the router to the MSC, a standard pair (Rx, Tx) of PCM cableshas to be used with 75 Unbalanced or 120 Balanced.

One end of the cable is connected to the Cisco router and the other end of

the cable will be connected to the MSC.

This cable is not referenced because on the MSC side there is no standardconnector, but client dependent. Usually this connection is done via the DDF.

4.3 Configure Router SoftwarePI 02 contains the procedures to configure the router software. After anintroduction to the router user interface, it describes how to perform the initialset up and configure the software. This includes how to customize the templatefile and download the edited file to the router.

5. Edit the configuration file, using a text editor.To customize the template file, refer to SPS for:

hostname, IP address, netmask and X25 address of the router

X.25 addresses of the OMC-R.

In the configuration file, all lines beginning with ! are interpreted ascomments by the Cisco IOS and ignored. These lines provide informationfor the user about the next commands.

In chapter 3, a configuration file is described in great details. Please read firstthe chapter before starting to create your own configuration file.


3BK 17422 4052 RJZZA Ed.04 55 / 76


4.3.2.2 Load the Template File to the RouterTo download the customized configuration file from the UNIX machine tothe Cisco router, do the following:

Common on Solaris

8 or 10

1. Check if the directory /tftpboot exists. If it doesn’t, create it:# mkdir /tftpboot

2. Copy inside of this directory the configuration file.





If the line is uncommented (it begins with tftp ), go to On the CiscoRouter (in section 3.3.4).

The two serial interfaces that connect the router to the OMC-R (Serial1/0 and Serial 1/1 ).


3BK 17422 4052 RJZZA Ed.04 57 / 76


4.4 Configure HostsPI 03 describes how to configure the syslog server and the host (A1353-RAMaster Host or remote side).

4.4.1 Configure X.25 Parameters

On the OMC-R side, the two X.25 links that are connected to the Cisco routermust be installed and configured with the right X.25 parameters.

1. Launch x25tool as root :# x25tool &

2. Check the parameters of the X.25 links, are according to the [1] B9BSS O&M Routing Configurations (3BK 17421 5002 PGZZA) , "OMCConfiguration". Refer to the section regarding the X.25 connection viaAter interface.

3. When done, exit the x25tool program.


4.4.2 Configure Hosts Database

1. On the OMC-R and the syslog machine (refer to the SPS to see if there isone) update the /etc/hosts file by adding a line containing the router’s IPaddress, then its hostname and (optional) its alias:

<IP address of the router> <router hostname> <routeralias>


58 / 76 3BK 17422 4052 RJZZA Ed.04


4.4.3 Configure Syslog Service

For the Cisco router, the syslog service is used to record all system messages(i.e. interface down/up) to a separate UNIX machine, in order to keep arecord of them

Usually only one host acts as a loghost (syslog server) within an operator’sIP network. The IP address of this host must have been given in the routerconfiguration profile (see Configure Hosts Database (Section 4.4.2)).

Due to the high CPU load that can occur in case of an interface failure, it isNOT recommended that the OMC-R host be used as a syslog server .

1. To make the syslog service available to the router, the following line has tobe added at the end of the file /etc/syslog.conf on the syslog server:

Syslog is very sensitive to the syntax of the commands in this file. There isat least one tab space between local7.debug and ifdef(... words in the linebelow. Also, there is one space after each comma in the same line.

local7.debug ifdef(‘LOGHOST’, /var/log/syslog,@loghost)

After this change has been made, the syslog daemon has to be restarted.

2. First, find the process id (pid ) for the syslogd daemon:# ps -edf | grep syslogd | grep -v grep

The pid is the number immediately after the user name (in this case root ).For example, if the result of the above command was:

root 242 1 0 Sep 08 ? 0:00 /usr/sbin/syslogd

the pid for the syslogd daemon is 242.

3. After you have identified the syslogd pid , restart the daemon:# kill -HUP <pid>

4.5 Connect BSCPI 04 describes how to connect the concerned BSCs to the OMC-R via theCisco router.

The procedures have to be performed on the MSC, Cisco and OMC-Rside. The PI assumes that the operations on the BSC side are done (seePrerequisites (Section 1.1.1)).

This PI is optional. Perform this PI only if new BSCs are specified in the SPS .

4.5.1 Configure MSC

Since the following procedures are strictly related to the type and manufacturerof the MSC, refer to the corresponding MSC documentation for detailedinformation about these tasks.

1. To establish the link between the MSC and Cisco router, follow the stepson the MSC side.


4.5.2 Add Additional PCM

1. In order to install the link between the MSC and the Cisco router, oneadditional PCM interface has to be declared on the MSC side. This PCMlink is used exclusively and cannot carry #7 links or traffic channels.


4.5.3 Create Semi-Permanent Connections (SPC)

1. To connect the time slots carrying X.25 data across the A Interface to thePCM link serving the router, several SPC (sometimes called Nailed-upConnection) have to be introduced (one for each X.25 link). How to do thisdepends on the type and manufacturer of the MSC. Refer to the MSCdocumentation to perform the required tasks and refer to the SPS forthe allocation of the time slots on the PCM link MSC-router and onthe PCM links MSC-BSCs (TCs) .


4.5.4 Declare BSS on OMC-R

Refer to the SPS for the X.25 addresses of the BSCs.

1. All BSCs must be declared on the OMC-R and with the right X.25addresses .

To declare them, refer to the B9 A1353-RA Methods Handbook.


60 / 76 3BK 17422 4052 RJZZA Ed.04


4.5.5 Configure Router

A route for each time slot has to be added in the X.25 routing table of theCisco.

When routing X.25, Cisco applies the following rules:

The list is scanned from beginning to end

If the route specifies a serial interface running X.25, the router will attempt to

forward the call over that interface

If no match is found, the call is cleared

If the interface is not operational, the remaining routes will be checked for

forwarding to an operational interface

If the interface is operational, but out of available virtual circuits, the callwill be cleared

A call cannot be forwarded on the interface it arrived on.

1. To start editing the routing table, enter the global configuration modeof the router:

<Router name># configure terminal

2. Then, for each time slot carrying X.25 , add in one row:<Router name>(config)# x25 route <address> int Serial2/0:<channel group>

where <address> is the X.25 address of the BSC sent over that timeslot, and <channel group> is the number of the virtual serial interfaceassociated to that time slot. (For time slots 1-30, this is the same as the timeslot number and for time slot 31, it is 0. See the template configuration file).

Refer to the SPS for allocation of time slots to the BSCs on the MSC-Ciscolink.

For example, if there is:

BSC1 with X.25 address 5100 on time slot 1

BSC2 with X.25 addresses 6100 and 6200 on time slots 9 and 31respectively.

you must add the following three routes (the router is called Router ):Router(config)# x25 route 5100 int Serial 2/0:1Router(config)# x25 route 6100 int Serial 2/0:9Router(config)# x25 route 6200 int Serial 2/0:0

3. When finished, exit global configuration mode:<Router name>(config)# exit

3BK 17422 4052 RJZZA Ed.04 61 / 76


4. Display the X.25 routing table:<Router name># show x25 route

The output of this command is a list of all entries in the X.25 routing table,one line per route:

The first two routes must be the OMC-R X.25 addresses forwarded to the

interfaces where the OMC-R is connected (Serial1/0 and Serial1/1 )

These routes were defined in section Configure Router Software (Section4.3) Configure Router Software in the configuration file

Then, the routes for all BSC addresses, defined in step 2 above.

5. Check that the OMC-R addresses are mapped on the Cisco serial interfacesand that all BSC addresses are mapped on the time slots available throughthe E1 controller.

If we take the example above (the two BSCs and we assume 1100 and 1200are the X.25 addresses of the OMC-R), the routing table looks like this:# Match Substitute Route to1 dest 1100 Serial1/02 dest 1200 Serial1/13 dest 5100 Serial1/0:14 dest 6100 Serial2/0:95 dest 6200 Serial2/0:0

6. If necessary, edit the routing table.

It is not possible to edit a route . To change it, however, you delete the routeand recreate it with the new parameters.

7. To delete a route, enter global configuration mode of the router:<Router name># configure terminal

8. Delete the route by entering the same command used to create it, butwith no at the beginning:

<Router name>(config)# no x25 route <address> intSerial 2/0:<channel group>

For example, to delete the route for BSC1 (see example above):Router(config)# no x25 route 5100 int Serial 2/0:1

9. Then add the corrected route. Next, exit global configuration mode and listthe routing table:

<Router name>(config)# exit<Router name># show x25 route

10. After all BSC addresses are mapped onto the corresponding time slots, savethe configuration to the non-volatile memory:

<Router name># write memory

4.5.6 Check Connections

1. Check the connection for:

Status of the interfaces

X.25 link status

X.25 redundancy

OMC-R application status.


4.5.7 Check Status of the Interfaces

1. List the status of the available interfaces:<Router name># show ip interface brief

Both Line and Protocol must be up for all used interfaces:

The ethernet interface (e.g. Ethernet 0/0 or FastEthernet0/0 ).

The two serial interfaces that connect the router to the OMC-R (Serial1/0 and Serial 1/1 )

The virtual serial interfaces associated to time slots, connecting the

BSCs (interfaces of type Serial 2/0:X ).


4.5.8 Check X.25 Link Status

Perform a PAD connection from an OMC-R to all BSCs. The status must be’connected’ even if there is no further reaction.

1. To do this, enter the following command on the OMC-R :# pad <BSC_X.25_address>

Where <BSC_X.25_address> is the X.25 address of the BSC with which youwant to establish the PAD connection.

The answer has to be:Connecting...Connected

If this is the case, the link status is OK. Otherwise there is a problemwith the X.25 link.

2. To disconnect, press [ Ctrl ] + [ p ] and [ a ].

3. When the PAD: prompt appears, type [ q ] and press [ Enter ].


3BK 17422 4052 RJZZA Ed.04 63 / 76


4.5.9 Check X.25 Redundancy

X.25 redundancy is checked by disabling one connection and checking thatthe connection has not been lost. The check is performed on the OMC-Rside and on the BSC side.

Because this check implies several administrative tasks of shutting up/downserial interfaces, the syslog service will be stopped to prevent overwhelming itwith unnecessary error messages.

Stop Syslog Service Enter the following commands in PRIVILEGED EXEC mode:<Router name># configure terminal<Router name>(config)# no logging <ip_address_ofsyslog_server><Router name>(config)# end

Check Redundancy on

OMC-R Side

1. From PRIVILEGED EXEC mode on the router, enter configuration mode:<Router name># configure terminal

2. Shut down the first link with the OMC-R:<Router name>(config)# interface serial 1/0<Router name>(config-if)# shutdown

3. On the OMC-R, check that the X.25 connection to each BSC has not beenlost. After that, bring the interface up:

<Router name>(config)# no shutdown

4. Shut down the second link with the OMC-R:<Router name>(config)# interface serial 1/1<Router name>(config-if)# shutdown

5. On the OMC-R, check that the X.25 connection to each BSC connectedthrough Cisco has not been lost.

6. After the connections have been checked, bring the interface up:<Router name>(config)# no shutdown

Check Redundancy on

BSC SidePerform this task only for BSCs with two X.25 links . See Configure Router(Section 4.5.5) for the associations between X.25 addresses and serialinterfaces of the router.

For all BSCs with two X.25 addresses, do the following:

1. Shut down one link with the OMC-R (<interface_id> is the identifier of theconcerned interface, i.e.Serial 2/0:3 for time slot 3, Serial 2/0:0 for timeslot 31).

<Router name>(config)# int <interface_id><Router name>(config-if)# shutdown

2. On the OMC-R, check that the X.25 connection to the BSC has not been lost.

3. After the connection has been checked, bring the interface up:<Router name>(config-if)# no shutdown

4. Repeat steps 1-3 for the second BSC link.

5. Repeat the above procedure for all BSCs with two X.25 links.

6. After all the checks have been done, exit configuration mode:<Router name>(config-if)# end

64 / 76 3BK 17422 4052 RJZZA Ed.04



Restart Syslog Service After all the checks have been done, restart the syslog service with thefollowing commands:

<Router name># configure terminal<Router name>(config)# logging <ip_address_ofsyslog_server><Router name>(config)# end

4.5.10 Check OMC-R Application Status

To check the OMC-R application status, perform a software audit on one BSC:

1. On the OMC-R, open a BSSUSM window for a BSC connected through theCisco router.

2. Follow the next menu path:

Configuration -> Software Management

The Software Management window for the BSC opens.

3. In the Software Management window, click on [ Software Audit ].

Wait for the Software Audit to be performed, that is, in the SoftwareManagement window, all BSC files must appear.

If the BSC files appear in the Software Management window, this meansthe X.25 connection between the OMC-R host and the BSC is correctlyconfigured at the application level.

4. Click on [ Close ] to exit the Software Management window.

5 Cisco 3700 Configuration Example


This chapter describes the main parts of a Cisco configuration file.

For this example the following data is used:X.25 addresses of the OMC-R: 1100 and 1200X.25 address of the router: 9900Hostname of the router: R3725T1IP address of the router: 172.16.101.3, netmask 255.255.0.0IP address of the syslog server: 172.16.106.20

3BK 17422 4052 RJZZA Ed.04 67 / 76


5.1 General Settings (1)The first lines, beginning with service or no service , are standardconfigurations to enable or disable some services available on the Cisco router.

Next, the router hostname, R3725T1, and the enable passwords are defined.Then x25 routing and ip routing are enabled for this router.

The part of the configuration file related to this example is as follows:!service timestamps debug datetimeno service udp-small-serversno service tcp-small-serversno service config!hostname R3725T1!enable secret tmp_pwdenable password cisco!ip routingx25 routing!

5.2 Controller E1 2/0In the lines that follow, the controller E1 is defined, together with thecorrespondence between the time slots on the PCM link and the channelgroups in the way the router will understand them.

As you can see, there is a one-to-one mapping of the time slots, the onlydifference is for time slot 31, which is mapped on channel 0.

The part of the configuration file related to this example is as follows:!! If you have NM-1CE1T1-PRI module (new PCM),! do nothing with the next line not commented.! If you have NM-1CE1B module (old PCM),! comment the following line:card type E1 2!controller E1 2/0channel-group 0 timeslots 31channel-group 1 timeslots 1channel-group 2 timeslots 2channel-group 3 timeslots 3. . .. . .. . .channel-group 28 timeslots 28channel-group 29 timeslots 29channel-group 30 timeslots 30!

68 / 76 3BK 17422 4052 RJZZA Ed.04


5.3 Interface Loopback0The next item defined in the configuration file is the interface Loopback0.This interface is only a virtual interface, it does not really exist on the router.Normally, it is only used for the link with another router.

The IP address defined for the Loopback0 interface is a dummy address. Usethe same address in your configuration file.

The advantage of this interface is that, since it is a virtual interface, once youbring it up, it never comes down. So the link performed through it remainsactive, regardless of the status or the interface FastEthernet0/0, for example.

Some extra configuration (no ip route-cache and no ip mroute-cache ) areneeded to completely configure the Loopback0 interface.

The part of the configuration file related to this example is as follows:interface Loopback0ip address 192.168.205.1 255.255.255.255no ip route-cacheno ip mroute-cache!

5.4 Interface FastEthernet0/0The next step is to configure the FastEthernet interface. Only one Ethernetinterface is used, so the other ones will not be configured. IP address -172.16.106.3 and netmask - 255.255.0.0 are only examples. You can findthese values in the SPS.

Some additional settings are entered (no ip route-cache and no ipmroute-cache ) to completely configure the interface.

Finally, the interface FastEthernet0/0 is brought up by the no shutdowncommand.

The part of the configuration file related to this example is as follows:interface FastEthernet0/0ip address 172.16.106.3 255.255.0.0no ip route-cacheno ip mroute-cachespeed autono shutdown!

3BK 17422 4052 RJZZA Ed.04 69 / 76


5.5 Interface Serial1/0 and Serial1/1This Cisco router has four serial interfaces available. These are used for theconnection with the HSI board of the OMC-Rs. The interfaces Serial1/0 andSerial1/1 are used for the link with the OMC-R. The interfaces Serial1/2 andSerial1/3 can be used for connecting a second OMC-R, but in this example theyare not used and not configured.

When defining the serial interfaces, no routing rule is yet defined. Therouting rules, that is, where the X.25 packets having a certain destinationwill be forwarded, are defined later, in the X.25 routing table. Here, only theX.25 parameters for each interface are set up, together with some specificconfiguration parameters.

First, no IP address is set up for the serial interfaces, using the no ip addresscommand. Then the no ip route-cache and no ip mroute-cache parametersare also set.

The encapsulation for the packets forwarded through the interface is set upas X.25 dce . Also, an X.25 address for the serial interface is provided; thisaddress is 9900.

Some default X.25 parameters are then defined: the input packet size (ips),output packet size (ops), incoming window size (win), outgoing window size(wout) and the clockrate for each interface.

Finally, each interface is brought up with no shutdown .

The part of the configuration file related to this example is as follows:

interface Serial1/0no ip addressencapsulation x25 dcex25 address 9900x25 ips 256x25 ops 256x25 win 7x25 wout 7clockrate 250000no shutdown!interface Serial1/1no ip addressencapsulation x25 dcex25 address 9900x25 ips 256x25 ops 256x25 win 7x25 wout 7clockrate 250000no shutdown!

5.6 Interface Serial2/0:0 and Serial2/0:1On the PCM link, there are 31 time slots available for communication. In thedefinition of the E1 controller, we have mapped each available time slot on thePCM link to a specific channel. The Cisco router interprets these channels asserial interfaces, similar to the situation in which we have 31 serial interfaces,not a PCM link with 31 time slots.

The result is that for communication on each time slot, we have to define asort of serial interface. This serial interface is different in notation from the realserial interface. Because the network module is inserted in slot 2 of the routerand there is only one E1 controller (controller 0) on the module, the name ofthe virtual serial interfaces are Serial2/0:0 , and Serial2/0:1 to Serial2/0:30 , atotal of 31 interfaces corresponding to 31 time slots.

The time slots (and corresponding serial interfaces) are used for communicationwith the BSCs.

Serial2/0:0 and Serial2/0:1 are only two examples of virtual serial interfacesconfiguration. In the template file, all these interfaces (from Serial2/0:0 to2/0:30) are configured in the same way.

For these interfaces, the following configuration is entered:

No IP address is allocated to this interface

Additional configuration is performed through the no ip route-cachecommand

The packet encapsulation is set to X.25 dce

The value for the highest two-way logical channel (htc) is set to 8

Some default X.25 parameters are configured: the input packet size (ips)

and the output packet size (ops) are set to 256

Some default LAPB protocol parameters are configured: timer T1 is set to

5000, timer T4 is set to 15 and counter N2 is set to 10

The transmitter-delay parameter is set to 100.

All interfaces are brought up with no shutdown .

5.7 Router EigrpEIGRP (or Enhanced IGRP) is an enhanced version of the Interior GatewayRouting Protocol (or IGRP) developed by Cisco Systems. It is designed forrouting in an autonomous system that contains large, arbitrarily complexnetworks with diverse bandwidth and delay characteristics.

If this protocol is set up correctly on the router, it will discover and include in theIP routing table the local IP network.

The command router eigrp 2667 is a default one.

The next two commands define the networks for which the protocol shouldperform the discover.

The first network, 192.168.205.0, is the network defined by the loopbackinterface.

The second network, 172.16.0.0, is the network containing the OMC-R hostand the Cisco1 router.

The next two commands configure some default settings: maximum-paths6 and no auto-summary .

The part of the configuration file related to this example is as follows:router eigrp 2667network 192.168.205.0network 172.16.0.0maximum-paths 6no auto-summary!

72 / 76 3BK 17422 4052 RJZZA Ed.04


5.8 General Settings (2)The next three lines are part of the router general settings.

The ip classless command is a default.

The logging console notification command configures the router to showsystem messages on the console screen.

The logging 172.16.106.20 command configures the router to send systemmessages to the syslog daemon on the UNIX machine with the IP address172.16.106.20. The UNIX machine must have the syslog daemon configuredas described in Configure Hosts (Section 4.4), ’Syslog Service’. The routersystem messages will be logged on that machine.

The part of the configuration file related to this example is as follows:ip classlesslogging console notificationslogging 172.16.106.20!

5.9 X.25 Routing TableThe following two lines, beginning with the x25 route command, configurethe X.25 routing.

The X.25 routing table is consulted when an incoming call is received, toforward it to its destination. The called X.121 address (destination hostaddress) is used to determine the route. When the destination address of theincoming packet fits the X.121 pattern in the routing table, the call is forwardedto the corresponding interface.

In the X.25 routing table of Cisco, the first entry specifies that any incoming callwith destination address 1100 will be forwarded to the interface Serial1/0. Thisaddress corresponds to a port on the HSI board of the OMC-R.

The second entry specifies that any incoming call with destination address1200 will be forwarded to the interface Serial1/1. This address correspondsto another port on the HSI board of the OMC-R.

Other entries, referring to the BSCs, will be added later when the BSCs areconnected.

The part of the configuration file related to this example is as follows:x25 route 1100 interface Serial1/0x25 route 1200 interface Serial1/1!

3BK 17422 4052 RJZZA Ed.04 73 / 76


5.10 General Configuration (3)The last lines in the file configure some default parameters.

The three lines starting with line configure, respectively, the console terminal,the auxiliary terminal and the standard VTY terminal: line con 0 , line aux0 and line vty 0 4 .

The next line is also a default setting for the terminal: exec-timeout 30 0 .

The lines password cisco and login set up the password for the loginconnection through a telnet command from another host in the network.

The configuration file ends with the end line.

The part of the configuration file related to this example is as follows:line con 0line aux 0line vty 0 4exec-timeout 30 0password ciscologin!end
