Enabling the Dummy Mode
The dummy mode enables a bit pattern for filling in for lost or corrupted frames. To enable dummy mode,
use the
dummy-mode
[
last-frame | user-defined
] command. The default is
last-frame
. The following is an
example:
Router(config-cem)# dummy-mode last-frame
Setting the Dummy Pattern
If dummy mode is set to user defined, you must use the
dummy-pattern pattern
command to configure the
dummy pattern. The range for
pattern
is from 0x0 to 0xFF. The default dummy pattern is 0xFF. The following
is an example:
Router(config-cem)# dummy-pattern 0x55
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.

relay function.
Supported Interface
The following interfaces are supported for the :
•
P2P and multipoint permanent virtual circuit (PVC) under the main interface.
•
P2P and multipoint PVC under the subinterface.
•
P2P and multipoint L2 PVC under the main interface
—
AAL5 and AAL0 (sustainable cell rate (SCR)
and peak cell rate (PCR)).
•
P2P and Multipoint L2PVC under the subinterface
—
