IP - Before delivery, the
IP address of the NE is set to 129.9.0.x.
The letter x indicates the basic ID.
In the HWECC solution, an IP address is set according to the following rules:
l The IP address, subnet mask, and default gateway of the gateway NE must meet the planning requirements of the external DCN.
l If an NE uses the extended ECC, the IP address must be in the same network segment.
l The IP address of other NEs must be set according to the NE ID. In this example, the IP address of an NE must be set in the format of 0x81000000+ID. That is, if the ID is 0x090001, the IP address must be set to 129.9.0.1.
Gateway IP - 0.0.0.0
Subnet Mask - 255.255.0.0
Extended ID 1 to 254 9 l Do not change the extended ID when the
number of actual NEs does not exceed the range permitted by the basic NE ID.
l It is recommended that this parameter takes the default value.
NSAP Address - - This parameter is valid only when the OSI
over DCC solution is applied. This
parameter is used to set only the area ID of an NSAP address. The other parts of the NSAP address are automatically generated by the NE.

5.1.6 Configuring Logical Boards
If the logical board corresponding to a physical board is not added in the slot layout, add the logical board in the slot layout. If the physical board is inconsistent with the logical board in the slot layout, delete the inconsistent logical board and add the correct logical board.
Prerequisite
l The NE user must have the authority of Operation Level or higher.
l All the boards must be installed correctly.
Tools, Equipment, and Materials
Web LCT
Context
The NE software manages a physical board by considering the physical board as one or more logical boards. In the OptiX RTN 620:
l An SCC physical board is considered as a logical SCC and a logical EOW board. The slot number of the logical SCC board is 2, and the slot number of the logical EOW is 21.
l Other physical boards of the IDU are considered as the logical boards with the same names.
The slot numbers of the logical boards are the same as the slot numbers of the corresponding physical boards.
An ODU is considered as an ODU logical board. The ODU logical slot number is 10 plus the slot number of the IF board connected to the ODU.
The STAT indicator on the physical IDU board will be lit only if the logical IDU board matches with the physical IDU board.
Procedure
Step 1 Click the Slot Layout tab and click Add Logical Boards.
Based on the slot layout, the NE automatically configures the logical boards that are required but still not be configured for certain physical boards.
Step 2 Optional: Right-click the slots in which boards are to be added, and select Add xxx. "xxx" refers to the boards to be added.
NOTE
Add the PXC board before you add the IF boards and service boards.
Manually adding the logical boards applies to the cases when relevant data need to be configured before the physical boards are installed.
Step 3 Optional: Right-click the slots in which boards are to be deleted, and select Delete.
Delete the services, clock, orderwire and protections on the boards before you delete the boards.

Example
Table 5-4 Parameters
Parameter Value Range Default Value Description
Working Mode HSB
FD SD
HSB l In 1+1 HSB protection mode, the system provides a 1+1 hot standby configuration for the IF board and ODU at both ends of each hop of a radio link to provide protection.
l In 1+1 FD protection mode, the system uses two channels that have a frequency spacing between them, to transmit and receive the same signal. The remote end selects signals from the two received signals. With the 1+1 FD protection, the impact of the fading on signal
transmission is reduced.
l In 1+1 SD protection mode, the system uses two antennas that have a space distance between them, to receive the same signal. The equipment selects signals from the two received signals.
With the 1+1 SD protection, the impact of the fading on signal transmission is reduced.
l The 1+1 FD protection mode and 1+1 SD protection mode are compatible with the 1+1 HSB switching function.
l Set this parameter according to the service planning information.
Revertive Mode Revertive Non-Revertive
Revertive l When this parameter is set to Revertive, 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.
l 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.
l It is recommended that this parameter takes the default value.
Parameter Value Range Default Value Description
WTR Time (s) 300 to 720 600 l This parameter is valid only when Revertive Mode is set to Revertive.
l When the time after the former working channel is restored to normal reaches the set wait-to-restore (WTR) time, a revertive switching occurs.
l It is recommended that this parameter takes the default value.
Enable Reverse Switching
Enable Disable
Enable l 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 Enable and the reverse switching conditions are met, the IF 1+1 protection switching occurs at the source end.
l This parameter is valid only when Working Mode is set to HSB or SD.
l 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.
Working Board IF ports - l In 1+1 FD/SD mode, two IF boards must
be installed as a pair in slots 5 and 7 (the IF board in slot 5 is recommended to be the main board) or in slots 6 and 8 (the IF board in slot 6 is recommended to be the main board).
l In 1+1 HSB mode, the IF boards can be installed in slots 5-8. It is recommended that you install two IF boards in a pair in slots 5 and 7 (the IF board in slot 5 is the main board) or in slots 6 and 8 (the IF board in slot 6 is the main board).
Protection Board
NOTE
The parameters Working Mode, Revertive Mode, WTR Time (s), and Enable Reverse Switching must be set to the same values at both ends of a radio link hop.
Postrequisite
l In the case of 1+1 HSB protection and 1+1 SD protection, you need to configure the IF/
ODU information of the main radio link later. The standby radio link automatically copies
the related information of the active microwave link except the transmission status of the ODU.
l In the case of 1+1 FD protection, you need to configure the IF/ODU information of the main radio link and the information of the standby ODU later. The standby radio link automatically copies the IF information of the main radio link.
NOTE
The default TX Status of an ODU is Unmute. Therefore, you need not configure the TX Status of the standby ODU after you create an IF 1+1 protection group.
5.1.8 Configuring the IF/ODU Information of a Radio Link
By configuring the IF/ODU information of a radio link, you can configure the IF/ODU information that is frequently used by the radio link.
Prerequisite
l The NE user must have the authority of Operation Level or higher.
l The IF boards and the ODUs to which the IF boards are connected must be added.
Tools, Equipment, and Materials
Web LCT
Precautions
l In 1+1 HSB/SD protection mode, one protection group corresponds to one radio link. In this case, you need configure only the IF/ODU information of the main equipment.
l In 1+1 FD protection mode, one protection group corresponds to one radio link. In this case, you need configure the IF/ODU information of the main equipment and the ODU information of the standby equipment.
l In the case of XPIC radio links, one XPIC workgroup corresponds to two radio links. The IF/ODU information of the radio links must be configured in the XPIC workgroup.
l In the case of N+1 protection mode, one N+1 protection group corresponds to N+1 radio links and the IF/ODU information of the N+1 radio links must be set separately.
