Coastcom D/I Mux III System User Manual page 88

Each 50-pin connector has two sets of pins for each line card slot, Channel A and Channel B. 2-
Wire voice cards require the T and R connections. 4-Wire voice cards require T, R, T1, and R1
connections. E&M signalling requires the addition of the E&M connections.
Tables on the following pages give detailed instructions connections appropriate for the 8-, 12-,
and 24-slot D/I Mux III shelf models. Make the connections to the 50-pin connectors according to
Tables 3-9 and 3-10. Table 3-11 shows the color coding for the 50-pin connector. (For more
information on connector pinouts, refer to Appendix E. Wiring and Cable Tables.)
