pportDs3LineBuildout

Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::pportDs3LineBuildout

OID (numeric): 1.3.6.1.4.1.277.1.4.2.1.46

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The line build out or line length specification for
the DS3 transmitter.

1-port ATM-UNI DS3 card
--------------------------
The accepted values are:

1 - 0 to 225 feet
2 - 226 to 450 feet

What is pportDs3LineBuildout?

This sets the DS3 transmitter's line build-out (cable-length compensation) for this port, chosen from a card-specific table; on the 1-port ATM-UNI DS3 card, value 1 covers 0-225 feet and value 2 covers 226-450 feet. As with the DS1 equivalent, getting this wrong on this specific DS3 port over- or under-drives the line for its actual cable run, producing pulse-shape distortion that manifests as BIP or line errors rather than an obvious link-down condition. A DS3 cross-connect run of about 350 feet from this port would call for build-out value 2 (226-450 feet) on the 1-port ATM-UNI DS3 card.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.46
snmpwalk -v2c -c public <target> CASCADE-MIB::pportDs3LineBuildout

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.46.1
snmpget -v2c -c public <target> CASCADE-MIB::pportDs3LineBuildout.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.4.2.1.46.1 i <value>
