bitsPortLineCode

Module: CM-FACILITY-MIB

OID (symbolic): CM-FACILITY-MIB::bitsPortLineCode

OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.16.1.10

Node type: OBJECT-TYPE

Type: BitsPortLineCode

Access: read-write

Description: This object represents the BITS Port Line Code. When the port is configured for a Line Type of T1, the valid values are t1-b8zs and t1-ami and the default value is t1-b8zs. When the port is configured for a Line Type of E1, the valid values are e1-hdb3 and e1-ami and the default value is e1-hdb3. When the port is configured for a Line Type of 2048kHz, the value is none.

What is bitsPortLineCode?

bitsPortLineCode is a read-write setting selecting the line coding used on the BITS port — t1-b8zs or t1-ami when the port's line type is T1, with a corresponding set of choices for E1. An administrator must match this to the line coding actually used by the upstream timing source, since a mismatch (e.g. AMI signal read as B8ZS) causes bit errors in the recovered clock. For example, a legacy T1 BITS feed still using older AMI equipment would need this changed from the t1-b8zs default to t1-ami to lock properly.
