APPENDIX C

Cable Pinouts

C-4

Table C-3 lists the pinout for the crossover adapter.

Table C-4 lists the pinout for the straight-through adapter.

CT1 and CE1 I/O Modules

CT1 I/O modules have 24 RJ-48C female connectors. CE1 I/O modules

have either 20 RJ-48C female connectors or two 25-pair female Telco

connectors. Figure C-3 shows the location of the ports on a CT1 I/O

module and the sequence of the pins in the RJ-48C connector. CE1 I/O

modules equipped with RJ-48C connectors have the same configuration

as CT1 I/O modules equipped with RJ-48C connectors.
