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 57
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.
