sts1LineCoding

Module: ACMIB

OID (symbolic): ACMIB::sts1LineCoding

OID (numeric): 1.3.6.1.4.1.1751.2.18.2.17.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This variable describes the variety of Zero Code Suppression used on this interface, which in turn affects a number of its characteristics. B3ZS refers to the use of specified patterns of normal bits and bipolar violations which are used to replace sequences of zero bits of a specified length.

What is sts1LineCoding?

Describes the Zero Code Suppression (ZCS) method used on the STS-1 SONET circuit to prevent long sequences of zeros that degrade signal quality. B3ZS is the standard method that replaces zero sequences with specific bipolar violation patterns to maintain synchronization on long-distance links. Example: A value of "B3ZS" means the interface uses Binary 3 Zero Suppression, replacing every 3 consecutive zeros with a bipolar violation pattern to keep the signal synchronized.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.17.1.2
snmpwalk -v2c -c public <target> ACMIB::sts1LineCoding

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.17.1.2.1
snmpget -v2c -c public <target> ACMIB::sts1LineCoding.1
