Feature interactions

The attendant at the Remote location is automatically assigned a separate
CAS key/lamp pair above the fifth loop key to control the CAS feature.
Additionally, a signal remote key is automatically assigned above the fifth
loop key on the consoles at the CAS Main location. On the M1250 and
M2250 consoles, the C/H key acts as the CAS key. If an Attendant Console
is not required at the Main location, up to ten multi-line telephones can be
equipped with a CAS key to control CAS operation.
The following packages are required for Centralized Attendant Service:
— Centralized Attendant Service Main (CASM) is package 26 and
— Centralized Attendant Service Remote (CASR) is package 27.
Access to special services
Special service circuits, such as WATS and FX trunks, can be either located
and controlled at one location or distributed among various locations with
each switch controlling access locally.
When special service circuits are located at the Main site, the CAS attendants
have trunk-group busy indicators and control of trunk-group access. In this
case, all Remote locations access the special-service circuits through TIE
trunks. TIE Trunk Group Access Restrictions (TGAR) at the Main site can be
arranged to provide dial access to the special services or to automatically
route incoming calls to the CAS attendants to control access manually.
If the special-service circuits are situated at a Remote location, they can be
dial-accessed and controlled through TGAR, or a unique access code can be
assigned to access the local attendant and bypass selection of a release link
trunk (RLT). The local-attendant directory number (DN) can also be used by
those who desire attendant-controlled connections.
Alarm lamps
Centralized Attendant Service (CAS) attendants do not receive major or
minor alarm indications for Remote locations. These alarms are provided at
the local console at each Remote location.
