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
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 (VIAS)
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.
If your switch contains a voice-synthesis board, ACA referral calls are accompanied by an audible
message identifying the type of ACA infraction encountered. The message is "Automatic circuit
assurance <long> or <short> holding time threshold has been exceeded for trunk group <#>
member number <#>."
•
Voice Message Retrieval
If you use Voice Message Retrieval, you can assign a nondisplay telephone as a referral
destination.
•
Wideband Switching
ACA treats wideband-trunk calls as a single-trunk call and therefore triggers a single referral call.
The call information shows the lowest B-channel trunk member associated with the wideband
channel.
