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.
