I am upgrading a Gr1225 UHF repeater to a MTR2000...
The Gr1225 has a ITA2000 tone remote adapter with a MC2500 desktop
The MC2500 has a phone line(rj11) connector going to the ITA2000,
with the audio being tapped out to an audio recorder...
Now the MTR2000 has a built in tone remote...
How do I find out what the four wires are on the RJ11 and in what order do I put them into the MTR2000...
This would have been so much easier if I had built the system from scratch and not upgrading somebodys elses work...
Thanks in advance...

Unless your running a 4 wire system, the red and green
wire on the RJ11 is for the 1st pair, the yellow and black
is for the second pair. The 2 center pins are the 1st pair
and the 2 outside pins is the second pair.

Can't you open up the former TRA and follow the traces to see (A) whether your system is operating as 2-wire system or 4-wire system and (B) which RJ leads are (A) the relevant 2-wires or (B) the RX line (from station to landline) and the TX line (from landline to station)?
In an MTR2000 "Line 1" of the wireline connector is the TX line for a 4-wire system and "Line 2" is the RX line. When programmed to work as a 2-wire system (RSS programming required), the 2-wires go into "Line 2."

Well I figured out what the whole problem was...
the person who did the configeration on the MCS2500 set it up as a FOUR wire setup, then at a juncion box in the middle of the wireing they decided to change it to a TWO wire set up...after I found that box all was good with that station...
thanks for the input on the problems...
