can contain one of the following modules: AG2120 COIC
Module, M10 Public Address Module, or M90 Signal Relay
Module.
The card provides the appropriate A/D and D/A conversions
and signal processing.
The standard card is supplied with 6 x AG2120 modules, 1
x M90 Signal Relay module and 1 x M10 Public Address
module.
AG2120 COIC Module
The AG2120 module provides PABX Loop Start lines with
circuitry for ring and loop current detection, A/D and D/A
conversions, and pulse and fl ash signalling.
M10 Public Address Module
The M10 Public Address Module provides a Public Address output with a
voltage free (24VDC 1Amp max) relay switch. The “microphone” output
is at approximately 0dBm (line-level). The LED to show the status of the
PA relay.
M90 Signal Relay Module
M90 Signal Relay module providing 2 low voltage (24VDC 1Amp max)
normally open relays for problem reporting. The LED shows the status of
the relays. The operation of the relays is set in the confi gurAID software.
