Attendant Group
Features
Centralized
Attendant Service
X When a CAS attendant extends a
call out over public facilities
through TAC or ARS access, digit
analysis is based on the location
of the RLT trunk. That is, CAS
attendants must dial as if they
were on the served switch in the
same location as the RLT trunk.
Combine switches in
different locations to
provide direct access to a
single attendant group
Centralized attendant
service is acquired from
another switch through an
RLT trunk
AUDIX X X If a call goes to AUDIX, and the
assigned AUDIX is far across the
WAN, a race condition can exist
between alerting with answer by
AUDIX, and establishment of an
inter-port-network connection
through the ATM WAN. If the WAN
loses, the AUDIX announcement
could be clipped or lost.
Avoid this problem by
providing local AUDIX
systems, each located
near its subscriber. If the
switch spans multiple time
zones, a separate AUDIX
for each time zone is also
desirable to provide the
correct timestamps for
recorded messages.
