FAQ-How to Query Parameters of the multi-section protection Ring of the NG-SDH Equipment on the NE Side and the Cross-Connect Side

Publication Date:  2019-07-04 Views:  115 Downloads:  0

Issue Description

Q:
The APS protocol for the multi-section protection of the NG-SDH equipment is transferred to the cross-connect board. When a fault occurs at the multi-section protection, you need to confirm whether parameters of the multi-section protection on the NE side and the cross-connect side are consistent. 
 

Alarm Information

Null

Handling Process

A:
Use common command lines to query parameters of the multi-section protection on the NE side and the optp command to query parameters of the multi-section protection on the cross-connect side.
NE side:
:cfg-get-rmsattrib:PgId;
For example:
:cfg-get-rmsattrib:1
MSSPR-PG-ATTRIBUTE
PG-ID LOCAL-NODEID WEST-NODEID EAST-NODEID WTR-TIME
1 2 3 4 300
Total records:1
Cross-connect side:
:optp:bid,0,ac,1,25,25,1;
For example:
//Query the parameters from the cross-connect board in slot 9:
:optp:9,0,ac,1,25,25,1
Optp cmd : 2525
01 00 02 03 04 01 2c 00 00 00 10
Total records:1
//Query the parameters from the cross-connect board in slot 10:
:optp:a,0,ac,1,25,25,1
Optp cmd : 2525
01 00 02 03 04 01 2c 00 00 00 10
Total records:1
//Note: The first parameter in the return of the optp command indicates the protection group ID, the third, fourth, and fifth parameter indicates local node, west node, and east node. The sixth and seventh parameters together indicate the WTR time. For example, the WTR time indicated by the parameters is 0x12c, that is, 300.
