dsx1ExtCfgLineBuildOut
Module: RFC1406Ext-MIB
OID (symbolic): RFC1406Ext-MIB::dsx1ExtCfgLineBuildOut
OID (numeric): 1.3.6.1.4.1.495.2.1.6.53.10.1.12
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Specifies the attenuation or Line Build Out to be used on the transmitter side of the line.
Options: For T1 1: 0 to 133 feet / 0 dB
2: 133 to 266 feet
3: 266 to 399 feet
4: 399 to 533 feet
5: 533 to 655 feet
6: -7.5 dB
7: -15 dB
8: -22.5 dB
For E1
1: 75 Ohm (coax. cable)
2: 120 Ohm (RJ45 shilded twisted pair)
3: 75 Ohm ( with protection resistor)
4: 120 Ohm ( with protection resistor)
5: 75 Ohm (with high return loss 1:1.15)
6: 120 Ohm (with high return loss 1:1.36)
7: 75 Ohm (with high return loss 1:1.36)
8: N/A
Default Value: 1
Configuration Changed: administrative
What is dsx1ExtCfgLineBuildOut?
This value selects the line build-out setting, meaning transmit attenuation for T1 or termination impedance for E1, to match the cabling in use on this port. Matching this to the actual cable run is necessary to avoid signal reflection or excessive loss, since T1 options are distance-based (feet of cable) while E1 options are impedance-based (coax versus twisted pair). For a T1 run of about 300 feet an admin would set this to 3 (266-399 feet), while an E1 line on 120-Ohm twisted pair would use option 2.
