Analog Communications Interface (ACI)
Description
The Analog Communications Interface (ACI) feature uses an analog ports (with associated relays) for
Music on Hold, External Paging, and Back Ground Music (BGM).
External Paging, External MOH and BGM
By setting the PRG10-03-02, COI to "1=Audio Port" at 408M-A1, the trunk ports CO2 to CO4 can be
used for audio port (External paging, External MOH, BGM).
Each CO ports are configured as follows, COI2 : Paging Out, COI3 : MOH In, COI4 : BGM In. System
can only have 1 BGM/MOH port. If more than one port are set as MOH, BGM the youngest 408M-A1
ports will be used. For example if expansion KSU2 and KSU3 have programmed for BGM or MOH,
KSU3 setting will be ignored and BGM/MOH of KSU2 will be active.
External paging can be set for each 408M-A1 units except 3rd Expansion KSU. So maximum 3
External paging can be usable.
Relay Control
1 KSU has 2 relay ports (J7) on 408M-A1 unit. The System can have up to 8 relay ports.
These relays can be used for External MOH, BGM resource, External Speaker, or Door Phone control
in accordance with PRG10-61-01 and PRG10-61-02 setting.
