IDU Product DescriptionOverview

2 OverviewThe indoor section consists of one IDU.

The IDU consists of baseband interfaces for data and management, two BB/Modemunits, a Controller unit, an Alarm Restitution Unit and a Fan unit. A single coaxial IF cable

connecting the BB/Modem unit with a very compact outdoor transceiver located close to

the antenna.

An unprotected 1+0 system consists of one assembly equipped with only one

BB/Modem unit; a 1+1 system consists of an assembly equipped with two BB/Modem

units.

Each BB/Modem unit is connected to the outdoor unit through a single coaxial cable

where main signal, indoor-outdoor service data and outdoor power supply are sent

together. The indoor unit is totally independent of the RF band chosen for the outdoor

unit, making the system very flexible and easy to deploy.

The STM-1 interface can be either electrical or optical.

Figure 2 shows the 1+0 IDU configurations.

Figure 3 shows the 1+1 IDU configurations.

3 Functional descriptionFigure 4 shows the block diagram of the IDU.

Figure 4 Indoor Section Block Diagram

Figure 4 shows the IDU and interfaces from a functional point of view as weel as the

functional parts of the I/O, Modem/IF, and power supply modules. The IDU comes with

the standard I/O facility which can be upgraded. In addition, the Modem/IF function is

modular. This allows the addition of a second Modem to support protection or ring archi-

tectures. The power supply is similarly modular too.

The major functions of the IDU can be summarized as follows:

– I/O Processing - The IDU comes with a standard I/O facility that includes support for

up to 16xE1 and 2x100Base-TX user payloads, 2x100Base-TX for SNMP, and voice

orderwire. Moreover, 1 x STM-1, can be added. The IDU architecture is flexible and

allows for the future addition of other I/O types.

– Switch/Framing - The IDU includes an Ethernet Switch and a proprietary Framer that

are designed to support 1+1 protection switching, ring architecture routing, and

overall network control functions.

– Network Processor - The IDU includes a Network Processor which performs SNMP

and Network Management functions.

– Modem/IF - The IDU Modem performs forward-error-correction (FEC) encoding,

PSK/QAM modulation and demodulation, equalization, and FEC decoding func-

tions. The IF chain provides a 350 MHz carrier and receives a 140 MHz carrier. The

13

IDU Product Description Functional description

built-in multiplexer function resides in the Modem/IF Module. Two modems can be

used for 1+1 protection or ring architectures.

– Power Supply - The IDU power supply accepts 48 Vdc and supplies the IDU and

ODU with power. A second redundant power supply may be added as an optional

module.

– For the STM-1 configuration, a user rate clock is recovered from clock recovery

NCO and provided to the STM-1 I/O card.

The Modem Processor and its associated RAM, ROM, and peripherals control

Modem/IF operation. The IDU interfaces the ODU to receive and provide modulated Tx

and Rx waveforms.

The Modem modulates and demodulates of the payload/wayside/SNMP data and

forward error correction using advanced modulation and coding techniques. By means

of the all-digital processing used, the Modem implements strong modulation and forward

error correction coding to minimize the number of bit errors and optimize the radio and

network performances.The Modem also scrambles, descrambles and interleaves/deinterleaves the data

stream in accordance with Intelsat standards to ensure modulation efficiency and resil-

ience to sustained burst errors. The modulation will vary by application, data rate, and

frequency spectrum. The highest order modulation mode supported is 128 Quadrature

Amplitude Modulation (QAM).

The IDU also provides the physical interface for the user payload and network manage-

ment. In the transmit mode, the Framer merges user payload with radio overhead-

encapsulated network management data. This combined data stream is transmitted

without any loss of user bandwidth. In the receive mode, the Framer separates the

combined data stream received from the Modem. The IDU supports Scalable Ethernet

data rates, such as 25 or 50 Mbps via the 100BaseT data interface port. The IDUprovides network management data on 10 Mbps ports accessible via the 10/100BaseTX

port. The Central Processor Unit (CPU) provides the embedded control and network

element functionality of the OAM&P. The CPU also communicates with other functions

within the IDU for configuration, control, and status monitoring. The CPU passes appro-

priate status information to the IDU front panel display.

The power supply converts -48 Vdc to the DC voltage levels required by each compo-

nent in the system.

The following table summarizes the main functions performed by each unit.

Unit Performed Logical function Note

Controller unit • IDU programming and supervision

• NMS management (SNMP)

• Alarm remotization (input and Putput)

Master IO unit • Process User Payload

• Manage Framer

• Manage Crosspoint Switch

• Provide Voice Orderwire

• Provides Data Orderwire

Note that Framer/Crosspoint Switch

is housed on Master IO card, this

means that switching and framing

capacity of the IDU depend on the

type of equipped Master I/O module.

– Enhanced GigE Master IO unit (par 3.3)

3.1 Controller2 Module

The "Controller2" Module is a new version of the Controller Module and provides

upgraded capabilities. It fits the same slot as the Controller Module and provides the

same front panel connections.

The Controller2 Module, with respect to the Controller Module has a Different Ethernet

switch: the one adopted in 42E1 Master Module is used in the Controller2 Module to

manage the NMS channel. The new switch is transparent to the user. There are no

changes to functionalities (e.g. Max MTU, NMS, etc) and there are no changes to the

SNMP MIBs. Full interoperability between Controller and Controller2. 4096 MACaddresses in Controller, 1024 MAC addresses in Controller2, Aging time: 300 s for Con-

troller and 300 s in Controller2.

The Controller2 module has 32Mbyte of FLASH memory as the Controller module.

3.2 Standard2 Master IO and Enhanced2 Master IO Modules

The "Standard2" Master IO Module and "Enhanced2" are new versions of the Standard

and Enhanced Master IO Modules, respectively. Moreover they provide upgraded capa-

bilities of the respective older module versions; they fit the Master IO Module slot and

provide the same front panel connections as the respective Standard and Enhanced

IDU Product Description Functional description

Master Modules. Standard 2 and Enhanced2 Master Modules are over-the-air compat-

ible with the already supported Master IO Modules.

Here follows the list of the main differences of both the new Modules with respect to the

Standard and Enhanced Modules, respectively. – Different Ethernet Switch (the same switch used in the 42E1 Master Module is

adopted). This resulted in enhanced QoS capabilities.

– Voice Order Wire Enhancements: the new Modules support party line VOW in

addition to the point-to-point mode previously supported. The party line mode was

already supported for the 42E1 Master IO Module. Two operating modes are sup-

ported: point-to-point and party line. The party line mode allows the voice traffic to

be sent to both east and west links if so selected by the user. When the party line

mode is selected, the handset's earpiece is fed summed voice data from both the

east and west links.

3.3 Enhanced GigE Master IO Module

This module is the same as the GigE Master IO Module with the features of the STM-1

Mux/Demux.

IDU Product DescriptionFeatures

4 Features

4.1 Payload Processing And User Interface FunctionalitiesPayload interfaces are: E1, STM1, Ethernet.

4.1.1 E1 payload processing (Standard, Standard2, Enhanced and

Enhanced2 Master I/O Unit)

The logical processing scheme is shown in Figure 5: E1s can be cross-connected

towards the Modems or User interface

Figure 5 E1 processing blockPerformance monitoring is not available for E1 payload. AIS and LOS alarms are avail-

able for each E1 channel.

4.1.2 E1 payload processing (42xE1 Master I/O Unit and 21xE1 Expansion

unit)

The core of the payload processing (framer, cross-point switch and interface with

modems) is housed in the Master IO module.

Figure 6 and Figure 7 describe the block diagram for 42xE1 master module and 21xE1

Expansion module.

The framer, included in the Master module, can manage the 42xE1 interfaces on the

front panel and the 21xE1 interfaces present on the front panel of 21xE1 Expansion

module.

The overall capability is 63 E1. The cross-point switch of the 42xE1 Master module is an

any-to-any Crosspoint Switch that allows E1 signals to be routed between front-panel

ports, east/west timeslots or ring timeslots.

Near and Far loopbacks are available for each E1 present on both 42xE1 master module

and 21xE1 expansion module.

Performance monitoring is not available for E1 payload.

AIS and LOS alarms are available for each E1 channel.

4.1.3 STM1 payload processing

4.1.3.1 Multiplexing structure

If Mux/Demux option is not used the STM1 is transparently transported. In this case the

IDU is a pure transport, no RST termination is performed: this is the only case supported

by SVR 1.0 (see Figure 8).

g The Mini IO module with STM1 interface can not be equipped when the 42xE1

master module is present . As a consequence:

– The Mux/Demux option is not applicable to the 42E1 Master module.

– It is not possible to transport the STM1 from line side to the radio side when

42E1 master module is used. Modes that include the STM1 rate can be config-

ured but they reserve an STM1 channel over the air that can not be managed

line-side.

Figure 8 STM1 payload processing block (no RST termination)

From SVR 1.1 the Mux/Demux option is available. This option requires the Expanded

Master IO module.The only structure that can be managed via Mux-Demux is TUG3-

VC12 (Asynchronous mapping) and the entire frame (63VC12) is completely termi-nated. This means that there is no pure SDH Add/Drop capability because the frame

over the air is not STM1 but it is a proprietary frame. Consequently this application has

no RST, nor MST regeneration processing, but the line-side termination is implemented.

STM1 clock is not transported over the air.

Mixed TUG3 structures are not supported.

Figure 9 STM1 payload processing block (Crosspoint switch)

Figure 10 STM1 Mux/Demux

Crosspoint switch provides any-to-any routing of E1s between front-panel ports, east

link, west link, and STM-1 Mux/Demux



20 A25000-A0300-F018-01-76P1



STM-1 Mux/Demux Option (From SVR 1.1)

– Provides for a STM-1 Terminal Mux/Demux capability

– It can Mux/Demux up to 63 x E1 from an STM-1 signal

– Performance monitoring via WebGUI and SNMP – Only the front-panel STM-1 signal may be routed to the STM-1 Mux/Demux

• E1s to be aggregated across multiple IDU nodes must be transmitted over the air as

E1s with the final IDU performing the STM-1 Mux/Demux

The SDH Regenerator Section Overhead bytes are processed as follows (line side,

incoming IDU):

– J0 - Regenerator Section Trace message sent on Tx, and received on Rx. The Rx

Path Trace message is compared to an expected message and an Alarm is raised

if they differ.

– E1 - Not used, but supportable based on interoperating equipment.

– F1 - Not used, but supportable based on interoperating equipment. – DCC1-3 - Not used, but supportable based on interoperating equipment.

The SDH Multiplex Section Overhead bytes are processed as follows (line side,

incoming IDU):

– E2 - Not used, but supportable based on interoperating equipment.

– DCC4-12 - Not used, but supportable based on interoperating equipment.

The SDH Path Section Overhead bytes are processed as follows (line side, incoming

IDU):

– J1 - Path Trace message sent on Tx, and received on Rx. The Rx Path Trace

message is compared to an expected message and an Alarm is raised if they differ.

– C2/V5 - Path Label. Transmitted C2 is always 02h (TUG). Transmitted V5 is either

00h (unequipped if VC is not in channel map) or 02h for Asynchronous mapping (not

configurable by the User). Received C2/V5 are monitored and alarms raised accord-

ingly.

The not used outgoing line side SOH Bytes are set to "0".

4.1.4 Ethernet payload Processing

The switch block in the diagram of Figure 12 is a standard Ethernet switch, with two (or

more) ports connected to the front-panel and two ports connected to the Framer (one

port for each modem). The Ethernet switch manages traffic using source and destination

addresses and forwards traffic to the appropriate ports.

The standard Ethernet switch allows traffic forwarding between the front-panel ports.

Refer to Figure 13.
