Table A-5 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 A-4 shows the location of the Telco
connectors on a CE1 I/O module and the sequence of the pins in the
connectors.
