Step Command Remarks
7. Configure the T1 operating
mode.
• Specify the unframed mode:
t1 t1-number unframed
• Specify the framed mode and
bundle timeslots:
a. (Optional.) undo t1
t1-number unframed
b. t1 t1-number channel-set
set-number timeslot-list
range [ speed { 56k |
64k } ]
By default, a T1 channel operates
in framed mode and is not
channelized.
When you place a T1 channel in
unframed mode, the system
automatically creates a
1.544-Mbps serial interface.
When you bundle timeslots on a T1
channel, the system automatically
creates a serial interface for the
bundle. The rate of the serial
interface is identical to timeslot rate
(54 kbps or 64 kbps) x number of
bundled timeslots.
8. (Optional.) Shut down the
specified T1 channel.
t1 t1-number shutdown By default, a T1 channel is up.

CPOS-E1 interface configuration example
Network requirements
As shown in Figure 5, branch nodes Router B through Router H are uplinked to the central node Router
A through E1 links. Router A aggregate these E1 links with a CPOS interface.
Add one more E1 link on Router B to expand its capacity. In addition, bind the two E1 links through an
MP-group interface.
