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 56 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.
Figure 56: CT1 I/O Module Ports
Table 23 lists the pinout for the CT1/CE1
connector.

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 57 shows the location of
the Telco connectors on a CE1 I/O module and the sequence of the pins in the
connectors.
Figure 57: CE1 I/O Module with Telco Connectors
Figure 58 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.
Figure 58: Twenty-Port Balun Panel
Table 24 and Table 25 list
the pinouts for the Telco connectors on each cable.
