Cisco T1 User Manual

Both payload-size and dejitter-buffer must be configured simultaneously.
Note
Setting the Dejitter Buffer Size
To specify the size of the dejitter-buffer used to compensate for the network filter, use the dejitter-buffer
command. The configured dejitter-buffer size is converted from milliseconds to packets and rounded up to
the next integral number of packets. Use the size argument to specify the size of the buffer, in milliseconds.
The range is from 1 to 32; the default is 5.
Shutting Down a CEM Channel
To shut down a CEM channel, use the shutdown command in CEM configuration mode. The shutdown
command is supported only under CEM mode and not under the CEM class.
Configuring CEM Parameter on CEM Interface
The CEM parameters can be configured directly on CEM interface. Follow these steps to configure CEM
parameters:
enable
configure terminal
interface cem 0/0/1
cem 0
payload-size 512 dejitter-buffer 12
xconnect 10.10.10.10 200 encapsulation mpls
exit
Verifying CEM Statistics for SAToP
Use the following commands to verify the pseudowire configuration for SAToP:
• show cem circuit—Displays information about the circuit state, administrative state, the CEM ID of the
circuit, and the interface on which it is configured. If cross connect is configured under the circuit, the
command output also includes information about the attachment circuit status.
