Displaying and maintaining CE3 interfaces
Task Command Remarks
Display the state information of a
CE3 interface.
display controller e3
[ interface-number ] [ | { begin |
exclude | include } regular-expression ]
Available in any view.
Display the configuration and state
of a serial interface formed on a
CE3 interface.
display interface serial interface-number

Available in any view.
Clear the controller counter of a
CE3 interface.
reset counters controller e3

Available in user view.
Shut down a CE3 interface. shutdown
Available in CE3 interface
view.
CAUTION:
Make sure you are fully
aware of the impact of the
shutdown action on your
network.
Bring up a CE3 interface. undo shutdown
Available in CE3 interface
view.
Shut down an E1 line. e1 line-number shutdown
Available in CE3 interface
view.
Bring up an E1 line. undo e1 line-number shutdown
Available in CE3 interface
view.
Shutting down/bringing up a CE3 interface also shuts down/brings up the E1 lines demultiplexed from
the CE3 interface, the serial interfaces formed by the E1 lines, and the serial interfaces created on E1
lines by means of timeslot bundling.
Shutting down/bringing up an E1 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 E3 or E1 lines, or by timeslot bundling on an E1
line, run the shutdown/undo shutdown command in the view of the corresponding serial interface.
Configuring a CT3 interface
Both T3 and T1 belong to the T-carrier system promoted by ANSI. T3 uses the digital signal level DS-3
and operates at 44.736 Mbps.
CT3 interfaces support two operating modes: T3 (unchannelized) and CT3 (channelized).
• In T3 mode, a CT3 interface is a synchronous serial interface with 44.736 Mbps of data bandwidth,
on which no timeslots are divided.
• In CT3 mode, a CT3 interface can be demultiplexed into 28 channels of T1 signals. Each T1 line
can be divided into 24 timeslots numbered 1 through 24. Different from E1, each line on a T1
interface can operate at either 64 kbps or 56 kbps. Therefore, the number of logical lines that can
