Analog Communications Interface (ACI)

Description
The Analog Communications Interface (ACI) feature uses a PGD(2)-U10 ADP (Door Phone/Paging)
adapter to provide two analog ports (with associated relays) for Music on Hold, External Paging, Door
Boxes and auxiliary devices such as tape recorders and loud bells. The system allows up to 48
PGD(2)-U10 ADPs (when used for ACI ports) for a maximum of 96 analog ports. Each PGD(2)-U10
ADP requires an unused port on an ESIB/E-U20.
Music on Hold
You can connect up to two customer-provided Music on Hold music sources to a PGD(2)-U10 ADP.
This lets you add additional music sources if the external source on the CPUII ETU or the internal source
is not adequate. By using PGD(2)-U10 ADPs, you could even have a different music source for each
trunk.
When the system switches the ACI analog port to a trunk on Hold, the PGD(2)-U10 ADP relay
associated with the ACI analog port closes. Use this ability 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 PGD(2)-U10 ADP relay associated with the port closes when the call goes through.
For Music on Hold, connect the music source to the PGD(2)-U10 ADP module. Connect the music
source control leads to the CTL (control relay) jack. Refer to the Electra Elite IPK II System Hardware
Manual for additional details.
External Paging
An ACI analog port can also be an External Page output. When connected to customer-provided
External Paging equipment, the ACI port provides External Paging. 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 PGD(2)-U10 ADP 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 PGD(2)-U10 ADP jack. Connect the amplifier
control leads to the CTL (control relay) jack. Refer to the Electra Elite IPK II System Hardware Manual
for additional details.
