Verifying FDL
Use the show controllers t1 command to verify the FDL setting:
Router# show controllers t1 0/2/0
T1 0/2/0 is up.
Applique type is SPA-8XCHT1/E1
Cablelength is long gain36 0db
No alarms detected.
alarm-trigger is not set
Soaking time: 3, Clearance time: 10
AIS State:Clear
Framing is ESF, Line Code is B8ZS, Clock Source is Line.
Data in current interval (750 seconds elapsed):
4000 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 1 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
0 Near-end path failures, 0 Far-end path failures, 0 SEF/AIS Secs
Invert Data on the T1/E1 Interface
If the interface on the 8-Port Channelized T1/E1 Serial SPA is used to drive a dedicated T1 line that does not
have B8ZS encoding, you must invert the data stream on the connecting CSU/DSU or on the interface. Be
careful not to invert data on both the CSU/DSU and the interface, as two data inversions will cancel each
other out. To invert data on a T1/E1 interface, use the following commands:
Command
Router# configure terminal
Router(config)# interface serial
slot/subslot/port:channel-group
Router(config-if)# invert data
