gdcHdslT1LineCoding

Module: GDCHDSL-MIB

OID (symbolic): GDCHDSL-MIB::gdcHdslT1LineCoding

OID (numeric): 1.3.6.1.4.1.498.11.1.3.3.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This variable describes the variety of Zero Code Suppression used on the link, which in turn affects a number of its characteristics.

E1 links, with or without CRC, use HDB3 or AMI.

AMI refers to a mode wherein no zero code suppression is present and the line encoding does not solve the problem directly. In this application, the higher layer must provide data which meets or exceeds the pulse density re- quirements, such as inverting HDLC data.

What is gdcHdslT1LineCoding?

Selects the zero-code-suppression line coding used on this T1 interface: ami(1) or b8zs(2). An administrator sets b8zs(2), the standard for modern T1 circuits, unless the connected equipment specifically requires legacy AMI coding.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.498.11.1.3.3.1.9
snmpwalk -v2c -c public <target> GDCHDSL-MIB::gdcHdslT1LineCoding

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.498.11.1.3.3.1.9.1
snmpget -v2c -c public <target> GDCHDSL-MIB::gdcHdslT1LineCoding.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.498.11.1.3.3.1.9.1 i <value>
