6.0 Remote Tone Control Configuration Example

FIGURE 14. Remote Tone Control Example

Line to Line Crosspatch, see Figure 14, 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 IP223 is configured for Tone mode

operation and is connected to a 2- or 4-wire lease line for Tone Remote operation of a LMR

mobile radio. Industry standard radio control tones are generated and coupled with voice audio for

control of distant radio locations. Control tones are decoded by either a Telex TRA-223 or

DSP-223 Tone Remote Adaptor which is directly connected to the LMR radio.

Receive audio from the LMR is connected to the I/O of the DSP-223 and amplified down the

2- or 4-wire line to Line 1 I/O of the IP-223. The IP-223 based on LAM passes audio to Line 2 of

the IP-223 and out to the RTS Intercom System for playback at keypanels. PTT commands on a

keypanel generate a relay closure and audio is inserted on Line 2 of the IP-223 COR and audio

inputs. This creates a PTT tone generation sent out Line 1 of the IP-223 onto the 2- or 4-wire line

to the remote radio adaptor, the tone is decoded and a relay closure to key the LMR is generated,

audio is coupled and passed to the radio.

The IP-223 must be configured for tone mode operation on line 1 and local mode on Line 2.

The IP-223's default username is admin and the password is blank.
