■ Trunk group number, trunk access code, and trunk group member
■ The type of referral (short or long holding time)
Interactions
■ Administrable Language Displays
You cannot administer languages for ACA messages.
■ AUDIX
Do not set the referral-call extension to a telephone that covers to AUDIX.
AUDIX could potentially overload with the volume of calls, because ACA
calls remain active for up to three minutes.
■ Busy Verification
Once you have identified a potentially defective trunk, you can use Busy
Verification to check it.
■ Centralized Attendant Services (CAS)
When CAS is activated, the referral-call destination must be on the local
switch. The system interprets a referral destination of 0 as the local
attendant, if one exists. The CAS attendant cannot activate or deactivate
ACA referral calls at a branch location.
■ Distributed Communications System (DCS)
Referral calls may be placed across a DCS network. One switch (the
primary) is administered to receive ACA referred calls from remote nodes
for all switches within the network. You must administer the ACA Remote
PBX Identification field on the Feature-Related System Parameters screen
with the PBX ID of the node that is designated as primary.
If ACA referral calls are sent off the switch that generates the referral, the
display and voicing information indicating the failed trunk is lost, even if
the referral call is made over a DCS network.
■ Night Service
Referral calls to the attendant are not placed if the system is in Night
Service mode.
■ Visually Impaired Attendant Service
If the attendant presses the Display Status button and an ACA call has not
been answered, then the words Automatic Circuit Assurance are voiced.
If a visually-impaired attendant presses the Display Status button and the
ACA call has been answered, then the words Automatic Circuit Assurance
and the extension assigned to the ACA call are voiced.
