Line Framing Format
Possible Settings: D4, ESF
Default Setting: ESF
Specifies the framing format for transmitted and received signals on the T1 network

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.
