Analog Communications Interface (ACI)
Description
The Analog Communications Interface (ACI) feature uses a PGDAD module to provide two analog
ports (with associated relays) for Music on Hold, External Paging or auxiliary devices such as tape
recorders and loud bells. The system allows up to 48 PGDAD modules (when used for ACI ports),
for a maximum of 96 analog ports. Each PGDAD module requires an unused port on an ESIU PCB.
● Music on Hold
You can connect up to two customer-provided Music on Hold music sources to a PGDAD
module. This lets you add additional music sources if the external source on the NTCPU PCB
or the internal source are not adequate. By using PGDAD modules, you could even have a dif-
ferent music source for each trunk.
When the system switches the ACI analog port to a trunk on Hold, the PGDAD relay associ-
ated with the ACI analog port closes. You can use this capability to switch on the music
source, if desired.
Extension users can dial the ACI analog port extension number and listen to the connected
music source. The PGDAD relay associated with the port closes when the call goes through.
For Music on Hold, connect the music source to the PGDAD module. Connect the music
source control leads to the CTL (control relay) jack. Refer to the Hardware Manual for addi-
tional details.
● External Paging
An ACI analog port can also be an External Page output. When connected to customer-pro-
vided External Paging equipment, the ACI port provides External Paging independent of the
Aspire NTCPU external paging input (the Aspire S CPU does not provide an external paging
input). To use the External Paging, an extension user just dials the ACI analog port extension
number and makes the announcement. The system broadcasts the announcement from the ACI
analog port and simultaneously closes the associated PGDAD relay. You can use the relay
closure to control the External Paging amplifier, if required.
This external paging zone is not included in external all call paging or combination paging
(internal and external).
For External Paging, connect the Paging amplifier to the PGDAD jack. Connect the amplifier
control leads to the CTL (control relay) jack. Refer to the Hardware Manual for additional
details.
● Auxiliary Device Control
The PGDAD module can control a customer-provided tape recorder. When an extension user
dials the ACI analog port extension number, they can automatically start the recorder and acti-
vate the record function. When the user hangs up, the recording stops and the tape recorder
turns off. For tape recording, connect the tape recorder AUX input jack to the PGDAD jack.
Connect the recorder control leads (if available) to the CTL (control relay) jack. Refer to the
Hardware Manual for additional details.
