Configuring T1/E1 CES SVCs
A CES module converts CBR traffic into ATM cells for propagation through an ATM network. CBR
traffic arriving on a CES module port must first be segmented into ATM cells. This cell stream is then
directed to an outgoing ATM or CBR port.

Typically you configure a switched VC between CES modules anywhere in your network. For simplicity,
Note
this example and the accompanying procedure describe how to create a switched VC between modules
in the same ATM switch router chassis.
