An Overview of the CAS Environment

The Centralized Attendant Service (CAS) feature allows system users served by
separate switches at two or more locations to concentrate the attendant positions
at one location. This location is called the CAS main. The other locations,
typically without attendants, are called CAS branches. All locations within the
CAS environment have separate LDNs.
Incoming calls to the CAS main are handled as if the switch were a stand-alone
system. Any attendant-seeking calls at a CAS branch are routed to the
attendant consoles at the CAS main over Release Link Trunks (RLTs). The
RLTs are special trunks that are used only for attendant-seeking calls from the
CAS branches. The CAS attendant cannot originate a call over an RLT.
The CAS calls may be any calls that would normally go to the local attendant
console. The CAS attendant answers these calls and then extends them (over
the same RLT) to the requested extension or external number at the branch.
When the CAS attendant releases, the RLT is free for another call. The
extended call will return to a CAS console if it is not answered within a preset
time.
The CAS calls can also be held at the console, placed on Remote Hold, or
released (ended). The CAS calls can be held on the console, just like any other
call. Remote Hold is a feature used by CAS attendants that allows a call to be
held at the branch location. This feature frees the console and the RLT for other
calls. As with extended calls, a call on Hold or Remote Hold will return to a CAS
console if it is not answered within a preset time.
To speed the dialing procedure when extending a CAS call, the CAS attendant
can use the following features:
