Iden Configuration Example; Ip-223 Setup - Telex IP-223 to RTS Intercom System Application Note

4.0 iDEN Configuration Example

An iDEN configuration example is shown in Figure 6. Line-to-line Crosspatch is enabled in the
IP-223. Control logic and audio (6-wire E&M) are generated by the RTS system; these are
connected to Line 2 I/O which is configured for local mode operation. Line 1 I/O of the IP-223 is
also configured for local mode operation with iDEN as the selected radio. A Telex NI-223 is
required for this interface.
Receive audio from the iDEN is connected to the Line 1 I/O of the IP-223. Based on LAM levels,
the IP-223 passes the audio to Line 2 and out to the RTS Intercom System for playback at
keypanels. PTT commands at the keypanel generate a relay closure that activates the COR logic at
the IP-223. The IP-223 then accepts audio on its Line 2 input. The crosspatch transfers the audio
from Line 2 to Line 1, and a relay closure is activated to key the iDEN. Audio is passed from the
IP-223 Line 1 to modulate the iDEN.

on the Per Line Setup for Line 1 must be selected.
