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.
