Note The four ABCD bits in the CAS mechanism are device-specific, depending on the manufacturer of the
voice/video telephony device that generates the CBR traffic. The ABCD bits of the CAS mechanism are
user-configurable.
Verifying a Soft PVC for Structured CES with CAS and On-Hook Detection Enabled
To show the on-hook detection configuration of a softPVC configured with structured CES and CAS
enabled, use the following EXEC command:
Example
The following example shows the soft PVC with CAS and on-hook detect ion enabled as hexadecimal
number 2 (shown in Figure 19-6):

Creating Multiple Structured Soft PVCs on the Same CES Port
This section describes how to create more than one structured soft permanen t virtual channel (soft PVC)
on the same CES T1/E1 port. Figure19-7 shows how you can configure multiple CES circuits on a single
T1/E1 port.
Note Typically you will configure a softPVC between CES modules anywhere in your network. For
simplicity, this example and the accompanying procedure describe how to create a soft PVC between
modules in the same ATM switch router chassis.
