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
.
