Line Framing Format

Possible Settings: D4, ESF

Default Setting: ESF

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

D4 – Uses D4 framing format.

NOTE: This setting is not recommended by network carriers. False yellow alarms may occur after traffic has been running and the channel returns to idle, or when there is light traffic when other settings are selected. ESF format does not create this problem.

ESF – Uses Extended Superframe framing format.

Line Coding Format

Possible Settings: AMI, B8ZS

Default Setting: B8ZS

Specifies the line coding format for the network interface.

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