DTE Line Coding: Position S2-3 sets the DTE line coding, including conversion.
A - AMI
B - B8ZS
Network Line Framing: Position S2-4 sets the CSU to the framing of the network
line. In the ESF mode, the unit responds to all T1.403 or 54016 messages.
A - ESF
B - D4
DTE Line Framing: Position S2-5 sets the CSU to the framing of the DTE line.
A - ESF
B - D4
PRM: Position S2-7 enables/disables sending a PRM (performance report message)
during AIS. If the unit detects a loss of sync from the DTE, an unframed all ones signal
is generated to the T1 facility. If Switch S2-1 is set for T1.403 operation, the unit inter-
rupts the AIS signal with a PRM once a second.
A - PRM enabled
B - PRM disabled
