The rear transition board uses two RJ-21 25-pair Telco connectors labeled
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.
See Table 4 on page 17 for signal definitions. See
Pinouts" on page 43 for the connector A and B pinouts.
