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

3.0 LMR Configuration Example

A line to line configuration example using an LMR is shown in Figure 2. The 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 on the Ip-223 which is configured for local mode
operation.
Line 1 I/O of the IP-223 is also configured for local mode operation and is directly connected to a
LMR radio.
Receive audio from the LMR is connected to the IP-223's Line 1 I/O. Based on COR (Carrier
Operated Relay) or LAM (Line Activity Monitor), the IP-223 passes this audio to the IP-223's
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 LMR. Audio is passed from the IP-223 Line 1 to modulate the
LMR.
