The rear transition board uses two RJ-21 25-pair Telco connectors labeled A and B to interface the audio
and control connections for eight E&M channels.
NOTE: Because of space limitations, a 180º RJ-21 connector is required. The CTP 4WE&M RTM
supports clips to secure the RJ-21 cable connections to the RTM.
The R1/T1 pair and the R/T pair are the audio inputs and outputs of each port, respectively. For example,
the audio input pair for port 0 is R1 and T1 on pins 2 and 27 of connector A. The audio output pair for
port 0 is R and T on pins 1 and 26.
