FIGURE 8.4 CAS APPLICATION EXAMPLE
The CAS Signaling Mode does not have a menu equivalent to the CONFIG =>INTERFACE =>T1/E1(ISDN-PRI)
=>ISDN menu described above. Both signaling modes have a mode-specific menu at the channel level, with
different names, but basically the same function. This menu, CONFIG =>INTERFACE =>T1/E1 =>
<CHANNEL>
=>SIGNALING, will be described in the next section. The Interface Configuration tree for E1/T1 with CAS Signaling
is shown in Figure 8.5
