Step Command Remarks
13. Set the FDL format for a T1
channel.
t1 line-number set fdl { ansi | att |
both | none }
Optional.
By default, FDL is disabled.
This operation applies only to T1
channels that are formed on CT3
interfaces, operate in channelized
mode, and use ESF as the T1
framing format.
14. Set the intended bandwidth
for the CT3 interface.
bandwidth bandwidth-value Optional.
15. Set the physical status
suppression time for the CT3
interface.
link-delay delay-time
Optional
By default, state change
suppression is disabled.
16. Restore the default settings for
the CT3 interface.
default Optional.
17. Return to system view.
quit N/A
18. Enter synchronous serial
interface view of an interface
formed by a CT3 interfaces.
interface serial
number/line-number:0
or
interface serial
number/line-number:set-number
N/A
19. Set the CRC mode.
crc { 16 | 32 | none }
Optional.
By default, 16-bit CRC is adopted..
Note:
FEAC = Far end and control signal; MDL = Maintenance data link; PPR = Periodical performance report
Displaying and maintaining CT3 interfaces
CAUTION:
Perform shutdown operations with caution, because once an interface is shut down, it stops operating.
Shutting down/bringing up a CT3 interface also shuts down/brings up the T1 lines demultiplexed from
the CT3 interface, the serial interfaces formed by the T1 lines, and the serial interfaces created on T1
lines by means of timeslot bundling.
Shutting down/bringing up a T1 line also shuts down/brings up the serial interface formed by it and the
serial interface created on it by means of timeslot bundling.
To shut down/bring up only a serial interface formed by T3 or T1 lines, or by timeslot bundling on a T1
line, perform the shutdown/undo shutdown command in the view of the corresponding serial interface.
To display and maintain CT3 interfaces:
