Line Framing Format

Possible Settings: D4, ESF

Default Setting: ESF

Specifies the framing format for transmitted and received signals on the T1 network interface.

Default Setting: B8ZS

Specifies the line coding format for the network interface.

AMI ± Uses Alternate Mark Inversion (AMI) line coding format.

B8ZS ± Uses Bipolar 8 Zero Substitution (B8ZS) line coding format.

Line Build Out (LBO)

Possible Settings: 0.0, ±7.5, ±15, ±22.5

Default Setting: 0.0

Specifies the line build out for the signal transmitted to the network.

0.0, ±7.5, ±15, ±22.5 ± Specifies line build out in dB.
