List Bearer Channel(LST BC)

Function

An OM command that queries the configuration information of the bearer channel (BC) at the FR layer.

To query the information of the BC at the FR layer in a specified subrack, set Subrack No..

To query the information of the specified BC at the FR layer, set Subrack No., Slot No., Port No., and Bearer Channel ID.

Note

None

Parameters

ID	Name	Description
SRN	Subrack No.	Meaning:Subrack No. Value range:0~11 Explanation: This parameter specifies the number of the subrack that holds the GEPUG. Default value:None
SN	Slot No.	Meaning:Slot No. Value range:0~27 Explanation: This parameter specifies the number of the slot in which the GEPUG is located. Default value:None
PN	Port No.	Meaning:Port No. Value range:0~31 Explanation: This parameter specifies the port number of the BC on the GEPUG. Default value:None
BCID	BC Identifier	Meaning:BC Identifier Value range:0~255 Explanation: Each bearer channel (BC) on an E1 is assigned a number to facilitate local management. This number is called bearer channel ID. The local BC number and the peer BC number can be different. For one BC, the timeslot distribution at one end of the E1 must be the same as that at the other end of the E1 link. Therefore, the BC is available for communication. Default value:None

Example

1. Query the data information of the BC at the FR layer (Subrack No. = 0):
LST BC: SRN=0;
The result is as follows:

O&M    #5409
%%LST BC: SRN=0;%%
RETCODE = 0  Operation succeeded
