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 58 shows the location of the Telco connectors on a CE1
I/O module and the sequence of the pins in the connectors.
