Appendix A

Connection Data

A.1 Scope

This appendix provides information on the type and pin allocation of the interface

connectors installed on the various MX-2100 modules.

In the direction field, the following conventions are used:

• IN – input to MX-2100

• OUT – output from MX-2100.

A.2 Supervisory Port Connector

The module supervision connector is a 9-pin D-type female connector, designated

Supervisory Port Connector (CONTROL DCE).

• The allocation of pins in the Supervisory Port Connector with DCE emulation

(used for direct connection to the supervisory terminal) is given in Table A-1.

• The pin functions with DTE emulation (used when a cross-over cable is used

for connection to a modem that provides the link to the supervisory terminal)

is given in Table A-2.
