If the 5536 Digital Modem RAS Support driver is installed on

Facility Data
Link Protocol(s) Facility Data Link protocols are used to exchange
messages between the board and the remote end of the
network. These messages are issued by the Telco to put
the board in loopback mode for testing when problems
occur. They are also used to transmit statistics about
physical transmission errors on the line.
Two protocols are available for the facility data link:
ANSI-T1-403 and ATT-54016. They are compatible
with each other.
Use the protocol(s) indicated by your Telco. If this
information is unavailable, select both protocols.
