1.2 Creating NE by Using the Manual Method

Step Action

1

2

NE ID: The ID refers to the basic ID. If the extended ID is not used, the basic ID of

an NE must be unique on the networks that are managed by the same NMS.

The NE ID consisting of the basic ID and extended ID identifies an NE on the

NMS.

Extended ID(1 to 254): If the number of existing NEs does not exceed the range

represented by the basic ID, do not change the extended ID.

Gateway Type: This parameter is set to Gateway if the new NE is a gateway NE.

It is set to Non-Gateway also if the new NE is a non-gateway NE. This parameter is set according to the DCN planning if the new NE can function

as a gateway NE or a non-gateway NE.

IP Address: The IP address of gateway NE.

Port: Communication port.

User Name: lct

Password: password






1.3 Creating NE by Using the Search Method

Step Action

1

2

Domain: When the IP address of the GNE is known, it is recommended that you

set the IP address range of the GNE as the search domain. In the case of initial

configuration, it is recommended that you set the 129.9.255.255 network

segment as the search domain.

Search for NE: It is recommended that you select Search for NE, add device after

search NE User. By default, NE User name is lct and Password is password.







1.4 Configuring the logical boards

Step Action

1

Based on the slot layout, the NE automatically configures the logical boards that

are required but still not be configured for certain physical boards.

The aqua slots mean that the physical boards have already there but still not beconfigured for logical boards.

1.5 Modifying the NE ID/Name

Step Action

1






Step Action

2

Modify the NE ID according to the engineering planning to guarantee that each

NE ID is unique. Modifying the NE ID does not interrupt services.

1.6 Creating XPIC Protection Group

Step Action

1

If the IF board is IFX2 or ISX2, the XPIC function can be supported.







Step Action

2

Set IF Channel Bandwidth to 28M or 56M according to the network planning file.

Set IF Channel Bandwidth to 56M if high-power ODUs are used.

Set the polarization directions of microwave links. It is recommended that you

install the two IFX2/ISX2 boards that form an XPIC workgroup in the slots that are

in the same row or column of the chassis. Set the IF port on the IFX2/ISX2 board

that is housed in the slot with a smaller slot number to Polarization direction-Vand the IF port on the other IFX2/ISX2 board to Polarization direction-H.

Set Link ID-V (link ID for the vertical polarization direction) and Link ID-H

according to the network planning file. These two parameters must be set to

different values, but Link ID-V must be set to the same value at the two ends of a

link and Link ID-H must be set to the same value at the two ends of a link.

Set Transmit Power (dBm). Transmit Power (dBm) indicates the maximum

transmit power of an ODU, and therefore its value must not exceed the rated

power range supported by the ODU. This parameter specifies the upper threshold

of the transmit power range of an ODU. After an ATPC adjustment, the transmitpower cannot exceed the value of this parameter.

Set Transmit Power (dBm) and Transmission Frequency (MHz) according to the

network planning file.

Set ATPC parameters according to the network planning file. Note that before the

antenna alignment, ATPC Enabled must be disabled.






Step Action

3

Set AM Enable Status according to the network planning file. Before antenna

alignment, ensure that AM Enable Status is disabled.

If you set AM Enable Status to Enabled, set Modulation Mode of the Guaranteed

AM Capacity and Modulation Mode of the Full AM Capacity according to the

network planning file.

E1 Capacity specifies the number of E1 services that can be transmitted in Hybrid

microwave frames. Set this parameter according to the network planning file. The

number of E1 services at both ends of a microwave link hop must be the same.

Otherwise, the services are unavailable.







1.7 Configuring N+1 Protection

Step Action

1

When multiple STM-1 or Hybrid microwave services are transmitted in the

point-to-point mode, you can adopt the N+1 protection.

2

WTR time(s): This parameter specifies the wait-to-restore (WTR) time. When the

time after the former working channel is restored to normal reaches the set WTR

time, a revertive switching occurs. It is recommended that you use the default

value.

SD enabled: This parameter specifies whether the SD switching function of N+1

protection is enabled. When this parameter is set to Enabled, the SD condition is

considered as a trigger condition of protection switching. It is recommended that

you set this parameter to Enabled.






1.8 Creating IF 1+1 Protection Group

Step Action

1







2

Working Mode: This parameter specifies the working mode of the IF 1+1

protection. Select HSB, SD, or FD from the Working Mode drop-down list. The FD

mode and SD mode are compatible with the HSB switching function.

Revertive Mode: When this parameter is set to Revertive Mode, the NE that is in

the switching state releases the switching and enables the former working channel

to return to the normal state some time after the former working channel is

restored to normal. When this parameter is set to Non-Revertive, the NE that is in

the switching state keeps the current state unchanged unless another switching

occurs even though the former working channel is restored to normal. It is

recommended that you set this parameter to Revertive Mode.

WTR Time(s): You can set WTR Time(s) only when Revertive Mode is set to

Revertive Mode. The range is 300 to 720. It is recommended that use the default

value.

Enable Reverse Switching: When both the main IF board and the standby IF board

at the sink end report service alarms, they send the alarms to the source end by

using the MWRDI overhead in the microwave frame. When this parameter at the

source end is set to Enabled and the reverse switching conditions are met, the IF

1+1 protection switching occurs at the source end. This parameter is valid only

when Working Mode is set to HSB or SD. Generally, if Working Mode is set to HSB,it is recommended that you set this parameter to Disabled; if Working Mode is set

to SD, it is recommended that you set this parameter to Enabled.

NOTE: Each of the parameters Working Mode, Revertive Mode, WTR Time(s),

and Enable Reverse Switching must be set to the same value at both ends of a

radio hop.






1.9 Configuring the IF/ODU Information of Microwave Links

Step Action

1

Work Mode: This parameter indicates or specifies the work mode of the radio link

in "work mode number, service capacity, channel spacing, modulation mode"

format. The IF1 board supports this parameter.

Link ID: This parameter indicates or specifies the ID of a radio link. As the identifier

of a radio link, this parameter is used to prevent incorrect connections of radio links

between sites. If the value of Received Radio Link ID does not match the preset

value of Link ID at the local end, the local end inserts the AIS signal to the

downstream direction of the service. At the same time, the local end reports

MW_LIM alarm to the NMS, indicating that the link IDs do not match. Each radio

link of an NE should have a unique link ID, and the link IDs at both ends of a radio

link should be the same.

Received Link ID: When the radio link becomes faulty, this parameter is displayed

as an invalid value.

IF Service Type: If the Integrated IP radio transmits Native E1 services, set this

parameter to Hybrid(Native E1+ETH); If the Integrated IP radio transmits NativeSTM-1 services, set this parameter to Hybrid(Native STM-1+ETH); If the SDH radio

transmits SDH services, set this parameter to SDH.

IF Channel Bandwidth: This parameter is not applicable to the IF1 board; The IFU2

board does not support the value 40M; The IFX2 board does not support the values

7M, 14M, and 40M; The ISX2 board does not support the values 7M and 14M.

AM Enable Status: The ISX2/ISU2 does not support the AM function when IF

Service Type is SDH.







1 Manually Specified Modulation Mode: This parameter specifies the modulation

scheme that the radio link uses for signal transmission. It is valid only when AM

Enable Status is set to Disabled.

STM-1 Capacity: If IF Service Type is Hybrid(Native STM-1+ETH), this parameter

can be set to 0 or 1. If IF Service Type is SDH, this parameter can be set to 1 or 2.

Enable E1 Priority: This parameter is valid only when AM Enable Status is set to

Enabled. For the ISU2 and ISX2 boards, this parameter is available when IF Service

Type is Hybrid(Native E1+ETH).

Full E1 Capacity: E1 service bandwidth in full capacity mode ≤ Service bandwidth in

full capacity mode - Service bandwidth in guarantee capacity mode + E1 service

bandwidth in guarantee capacity mode. In addition, the number of E1 services in

full capacity modulation mode should be smaller than or equal to the maximum

number of E1 services in full capacity modulation mode.

2

Power to Be Received(dBm): This parameter is used to set the expected

receive power of the ODU and is mainly used in the antenna alignment stage.

After this parameter is set, the NE automatically enables the antenna

misalignment indicating function. When the antenna non-alignment indication

function is enabled, if the actual receive power of the ODU is 3 dB lower thanthe power expected to be received, the ODU indicator on the IF board

connected to the ODU blinks yellow (300 ms on, 300 ms off), indicating that the

antenna is not aligned.

After the antenna alignment, after the state that the antenna is aligned lasts for

30 minutes, the NE automatically disables the antenna misalignment indicating

function.






Chapter 2 TDM Services Configuration

Steps Description Remarks

1 Configuring Cross-Connections

2 Configuring Cross-Connections for SNCP Services

2.1 Configuring Cross-Connections

Step Action

1

E1 Priority: This parameter is available only if the E1 priority function is enabledfor the ports configured in the cross-connections. If E1 Priority is set to High,

transmission of the E1 service is ensured in any modulation scheme. If E1 Priority is

set to Low, transmission of the E1 service is ensured only in full-capacity

modulation scheme. If the service priority is not specified during service creation,

E1 Priority is None. In this case, the E1 priority of a service needs to be changedafter the service is created.

Activate Immediately: This parameter specifies whether to immediately activate

the configured service. To immediately deliver the configured SDH service to the

NE, set this parameter to Yes.

NOTES: When 1+1 protection or 1+1 linear MSP is configured for a TDM service,

you need to configure the TDM service only on the working channel. When N+1

protection is configured for TDM services, you need to configure the extra service

on the protection channel if the extra service needs to be transmitted on the

protection channel.







2.2 Configuring Cross-Connections for SNCP Services

Step Action

1

Revertive Mode: This parameter determines whether to switch the service from

the protection channel to the original working channel after the fault is rectified. If

this parameter is set to Revertive, the service is switched from the protection

channel to the original working channel. If this parameter is set to Non-Revertive,

the service is not switched from the protection channel to the original workingchannel. It is recommended that you set this parameter to Revertive.

Hold-off Time (100ms): When a line is faulty, SNCP switching can be performed on

the NE after a delay of time to prevent the situation where the NE performs SNCP

switching and other protection switching at the same time. If only the SNCP

scheme is available, it is recommended that you set the hold-off time to 0.

Configure SNCP Tangent Ring: After the Configure SNCP Tangent Ring checkbox

is selected, you can quickly configure the SNCP service for the SNCP ring tangent

point. In normal cases, it is recommended that you do not select this checkbox.

Activate Immediately: After the Activate Immediately checkbox is selected, you

can immediately activate the created SNCP service.






Chapter 3 Configuring Hybrid Ethernet ServicesSteps Description Remarks

1 Configuring the Parameters of Ethernet Ports

2 Configuring the Parameters of IF_ETH Ports

3 Configuring LAGs

4 Configuring QinQ Links

5 Configuring E-Line Services

6 Configuring ERPS

7 Configuring 802.1d Bridge-Based E-LAN Services

8 Configuring 802.1q Bridge-Based E-LAN Services

9 Configuring 802.1ad Bridge-Based E-LAN Services

3.1 Configuring the Parameters of Ethernet Ports

Step Action

1







2

If set Port Mode to Layer 2, Encapsulation Type can be set to Null, 802.1Q, or

QinQ. If you set Port Mode to Layer 3, Encapsulation Type can be set to 802.1Q

only. In this case, the port can be used to carry tunnel services.

Encapsulation Type:

For P2P E-Line services and IEEE 802.1d bridge-based E-LAN services, set

Encapsulation Type to Null.

For VLAN-based E-Line services and IEEE 802.1q bridge-based E-LAN

services, set Encapsulation Type to 802.1q. For QinQ-based E-Line services and IEEE 802.1ad bridge-based E-LAN

services, set Encapsulation Type to Null if the UNI port allows access of

untagged frames; set Encapsulation Type to 802.1q if the UNI port allows

access of only tagged frames; set Encapsulation Type to QinQ in the case of

the NNI port.

For an Ethernet port that is connected to the external equipment, set Working

Mode to a value the same as that of the external equipment (Generally, Working

Mode of the external equipment is set to Auto-Negotiation.) For Ethernet ports

within a network, set Working Mode to Auto-Negotiation.

When jumbo frames are transmitted, set Max Frame Length(byte) according to the

actual length of the jumbo frames. Otherwise, it is recommended that Max Frame

Length(byte) takes its default value.






3

For P2P E-Line services and IEEE 802.1d bridge-based E-Line services, you need

not set the Layer 2 attributes.

For VLAN-based E-Line services and IEEE 802.1q bridge-based E-LAN services,

set Tag to Tag Aware if the port allows the access of only the tagged frames, set

Tag to Access if the port allows the access of only the untagged frames, and set

Tag to Hybrid if the port allows the access of the tagged frames and untagged

frames. Set Default VLAN ID and VLAN Priority according to the network planning

file.

For QinQ-based E-Line services and IEEE 802.1ad bridge-based E-LAN services,

if the port functions as a UNI port and Encapsulation Mode is set to 802.1Q, Tag

must take its default value Tag Aware. For an NNI port that is connected to the

external equipment, set QinQ Type Domain according to the T-PID of the S-VLAN

that is supported by the external equipment. For an NNI port within the network,

QinQ Type Domain takes its default value.







4

Under Advanced Attributes, set MAC Loopback, PHY Loopback and query the

port rate. This operation is mandatory when you need to enable the port self-loop

test and automatic loopback shutdown functions or to enable the broadcast packet

suppression function.

Set Loopback Check, Loopback Port Shutdown, Enabling Broadcast Packet

Suppression, and Broadcast Packet Suppression Threshold according to the

requirements.

Suggestions of Enabling Broadcast Packet Suppression:

Enabling Broadcast Packet Suppression specifies whether to restrict the

traffic of broadcast packets according to the ratio of the broadcast packets to

the total packets. If a broadcast storm may occur on the equipment at the

opposite end, set this parameter to Enabled. For E-LAN services, it is

recommended that you set this parameter to Enabled. This parameter is

applicable to E-LAN services in the ingress direction.

Speed Transmission at L2: If this parameter is set to Enabled, the Layer-2

Ethernet packets transmitted at microwave ports will be compressed to improve

transmission efficiency. If the Layer 2 header compression function can be enabled

for the ISU2 or ISX2 board, it is recommended that you set Speed Transmission at

L2 to Enabled. The settings of Speed Transmission at L2 must be the same at both

ends of a radio link.






3.2 Configuring the Parameters of IF_ETH Ports

Step Action

1


QinQ. If set Port Mode to Layer 3, Encapsulation Type can be set to 802.1Q only. In

this case, the port can be used to carry tunnel services.

2

Under Advanced Attributes, set MAC Loopback and PHY Loopback and query the

port rate.

If you set Speed Air Interface Transmission at L2 to Enabled, the Layer 2 Ethernet

packets received by the IF_ETH port are compressed for higher transmission

efficiency. The L2 packet header compression function is available for the

ISU2/ISX2, it is recommended that you set Speed Air Interface Transmission at L2to Enabled for both ends of the link.

If you set Speed Air Interface Transmission at L3 to Enabled, the IP packets

received by the IF_ETH port are compressed for higher transmission efficiency.

When the L3 packet header compression function is available for the ISU2/ISX2, it

is recommended that you set Speed Air Interface Transmission at L3 to Enabled for

both ends of the link.







3.3 Configuring LAGs

Step Action






1


QinQ. If set Port Mode to Layer 3, Encapsulation Type can be set to 802.1Q only. In

this case, the port can be used to carry tunnel services.

Automatically Assign: This parameter indicates whether LAG No. is allocated

automatically. When Automatically Assign is selected, LAG No. cannot be set.

LAG Type:

Static: You can create a LAG. When you add or delete a member port to or

from the LAG, the Link Aggregation Control Protocol (LACP) protocol isrequired. In a LAG, a port can be in selected, standby, or unselected state.

The aggregation information is exchanged among different equipment

through the LACP protocol to ensure that the aggregation information is the

same among all the nodes.

Manual: You can create a LAG. When you add or delete a member port, the

LACP protocol is not required. The port can be in the up or down state. The

system determines whether to aggregate a port according to its physical

state (UP or DOWN), working mode, and rate.

Load Sharing: Sharing: Each member link of a LAG processes traffic at the same time and

shares the traffic load. The sharing mode can increase a bandwidth utilization

for the link. When the LAG members change, or certain links fail, the system

automatically re-allocates the traffic.

Non-Sharing: Only one member link of a LAG carries traffic, and the other

link is in the standby state. In this case, a hot backup mechanism is provided.

When the active link of a LAG is faulty, the system activates the standby link,

thus preventing link failure.







1 Load Sharing Hash Algorithm：This parameter is valid only when Load Sharing of

a LAG is set to Sharing. After the configuration data is deployed, Load Sharing

Hash Algorithm takes effect for the entire NE. For PW-carried UNI-NNI E-Line

services, Load Sharing Hash Algorithm cannot be set to MPLS Label.

System Priority

This parameter indicates the priority of a LAG. The smaller the

value of System Priority, the higher the priority.

Switch LAG upon Air Interface SD

This parameter specifies whether to enable the

switching triggered by bit errors. If this parameter is set to Enabled, the

MW_BER_SD alarm will trigger the LAG switching at the air interface.

Main Port

This parameter specifies the main port in a LAG. After a LAG is created,

you can add Ethernet services to the main port only. Services cannot be added to a

slave port. When Load Sharing is set to Non-Sharing, the link connected to the

main port is used to transmit the services, and the link connected to the slave port

is used for protection.

3.4 Configuring QinQ Links

Step Action

1

QinQ Link ID

The OptiX RTN 900 supports 1024 QinQ links, whose IDs must be

different from each other.

S-Vlan ID: This parameter specifies the VLAN ID (at the network operator side) for

the QinQ link. This parameter is set according to the planning information.






3.5 Configuring E-Line Services

Step Action

1

BPDU：This parameter specifies the transparent transmission ID of the bridge

protocol data unit (BPDU) packets. It is used to indicate whether the E-Line service

transparently transmits the BPDU packets. If the BPDU packets are used as the

service packets and transparently transmitted to the opposite end, set this

parameter to Transparently Transmitted. That is, the parameter value

Transparently Transmitted takes effect only if Encapsulation Type of the source

and sink ports of the E-Line service are Null. In other cases, set this parameter to

Not Transparently Transmitted. This parameter is set according to the planning

information.

If Source VLAN ID and Sink VLAN ID are blank, it indicates that you create a

point-to-point transparently transmitted E-Line service. If you need to create a

VLAN-based E-Line service, enter the VLAN IDs as planned. Set Direction to UNI-UNI. For QinQ-based E-Line services, set Direction to

UNI-NNI.







2

The VLAN ID of the UNI-UNI E-Line service can be converted after a VLAN

forwarding table item is created. In this case, a service from Source Interface to

Sink Interface carries the VLAN ID specified in Sink VLAN ID when the service is

transmitted from Sink Interface.

The VLAN ID in a VLAN forwarding table item is converted unidirectionally and

can be converted from Source VLAN ID to Sink VLAN ID only. The VLAN ID can be

converted bidirectionally only when the other VLAN forwarding table item is

configured reversely.

In normal cases, Ethernet services are bidirectional. Hence, you need to set

bidirectional conversion of VLAN IDs.






3.6 Configuring ERPS

Step Action

1

ERPS ID: Set ERPS ID to a value between 1 and 8. The ERPS ID must be unique.

RPLOwner Ring Node Flag：This parameter specifies whether the node on the ring

is the ring protection link (RPL) owner. Only one node on the ring can be set as the

RPL owner for each Ethernet ring.

RPL Port：There is only one RPL port and this RPL port must be the east or west

port on the RPL owner node.

Control VLAN：It is used for isolating the dedicated R-APS channel. Therefore, the

VLAN ID in Control VLAN cannot be duplicate with the VLAN IDs that are

contained in the service packets. The Control VLAN must be set to the same value

for all the NEs on an ERPS ring.

Destination Node: This parameter indicates the MAC address of the destination

node. The default destination MAC address in the R-APS packets is always

01-19-A7-00-00-01.







2

Hold-Off Time(ms): It is used for negotiating the protection switching sequence

when the ERPS coexists with other protection schemes so that the fault can be

rectified in the case of other protection switching (such as LAG protection) before

the ERPS occurs. If only ERPS protection is configured, set Hold-Off Time(ms)to 0.

If ERPS protection is configured with LAG, set Hold-Off Time(ms) to 500.

Guard Time(ms): The nodes on the ring continuously forward the R-APS packets to

the Ethernet ring. As a result, the outdated R-APS packets may exist on the ring

network. After a node on the ring receives the outdated R-APS packets, an

incorrect ERPS may occur. The ERPS guard timer is an R-APS timer used for

preventing a node on the ring from receiving outdated R-APS packets. When a

faulty node on the ring detects that the switching condition is cleared, the node

starts up the guard timer and starts to forward the R-APS (NR) packets. During this

period, the R-APS packets received by the node are discarded. The received R-APS

packets are forwarded only after the time of the guard timer expires.

WTR Time(mm:ss) The WTR time refers to the duration from the time when the

working channel is restored to the time when the switching is released. When the

working channel is restored, the WTR timer of the RPL owner starts up. In addition,

a signal that indicates the operation of the WTR timer is continuously output in the

timing process. When the WTR timer times out and no switching request of a

higher priority is received, the signal indicating the operation of the WTR timer is

not transmitted. In addition, the WTR release signal is continuously output. The

WTR timer is used to prevent frequent switching caused by the unstable working

channel.

Packet Transmit Interval(s): It specifies the interval for transmitting the R-APS

packets. It is recommended that this parameter take its default value.






3.7 Configuring 802.1d Bridge-Based E-LAN Services

Step Action

1

Tag Type:

C-Awared: indicates that the packets are learnt according to C-Tag (the

VLAN tag on the client-side). To create the 802.1q bridge, set this parameter

to C-Awared.

S-Awared: indicates that the packets are learnt according to S-Tag (the

VLAN tag at the carrier service layer). To create the 802.1ad bridge, set thisparameter to S-Awared.

Tag-Transparent: indicates that only the Ethernet packets that do not

contain VLAN tags are accessed. To create the 802.1d bridge, set this

parameter to Tag-Transparent.

Self-Learning MAC Address: If the MAC self-learning function of an Ethernet LAN

is enabled, the Ethernet LAN learns an MAC address according to the original MAC

address in the packet and automatically refreshes the MAC address forwarding

table. If the MAC self-learning function of an Ethernet LAN is disabled, a static

MAC address forwarding table is recommended to be configured.

MAC Address Learning Mode: When the bridge uses the SVL mode, all the VLANs

share one MAC address table. If the bridge uses the IVL mode, each VLAN has an

MAC address table.

NOTES: To better isolate services that are converged and to prevent broadcast

storm resulting from a service loop, you can configure a split horizon group for the

E-LAN services at the specified nodes. The logical ports in one split horizon group

cannot forward packets to each other.

4

Split Horizon Group Member: The OptiX RTN 900 supports only the division of the

split horizon group members according to the Ethernet physical port. If a UNI or

NNI logical port of the 802.1ad bridge is added to a split horizon group member,

the physical port that is mounted with the logical port is automatically added to the

split horizon group member.
