2-OPX MODULE
Using the 2-OPX Module
The 2-OPX Module provides two 2500 type analog circuits for
connection to on-premise 2500 type single line devices (i.e.,
telephones, fax machines, modems, etc.) and to telco OL13B/C
OPX circuits. The 2-OPX Module must be connected to an odd
port.Although it uses a single digital extension circuit for
power and signaling, the 2-OPX Module disables the next con-
secutive (even) port.

3-ACI MODULE
Using the 3-ACI Module
The 3-ACI Analog Communications Interface (ACI) provides
three analog ports (with associated relays) for Music on Hold,
External Paging or auxiliary devices such as loud bells and tape
recorders (Call Recording allows only incoming calls to be
recorded). The 3-ACI uses a single digital extension circuit for
power and signaling and provides 3 ACI software ports. You
can have a maximum of two 3-ACI’s in the system (which pro-
vides 6 ACI...
