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.
Table C-5 lists the pinout for the CT1/CE1 connector.
Table C-5 CT1/CE1 I/O module - RJ-48C connector pinout
For CE1 I/O modules with Telco connectors, the other ends of the cables are attached to a balun panel that splits the signals from two Telco connectors to 20 pairs of BNC connectors. We supply the Telco cables if you purchase a balun panel. Figure C-4 shows the location of the Telco connectors on a CE1 I/O module and the sequence of the pins in the connectors.
Figure C-5 shows the location of the 20 pairs of BNC connectors on a balun panel. The cables from the CE1 I/O module are plugged into the two 50-pin Telco connectors on the other side of the panel.
Table C-6 lists the pinout for the Telco connectors on each cable.
