Configuring FDL

Facility Data Link (FDL) is a 4-kbps channel provided by the Extended Super Frame (ESF) T1 framing format.
The FDL performs outside the payload capacity and allows you to check error statistics on terminating
equipment without intrusion. To configure FDL, use the following commands:
SUMMARY STEPS
1. Router# configure terminal
2. Router(config)# controller sonet slot/subslot/port
3. Router(config)# sts-1 sts-#
4. Router(config-ctrlr-sts1)# mode {ct3 | ct3-e1 | t3 | vt-15}
5. If vt-15 mode was selected:
6. Router(config-ctrlr-sts1)# t1 t1# framing {sf | esf}
7. Router(config-ctrlr-sts1)# t1 t1# fdl ansi
