AUX Port Interface
The Auxiliary (AUX) port connects to the LAN Adapter for SNMP or Telnet
applications, or to another DSU/CSUs COM port for daisy chain connectivity.
(The
SNMP LAN Adapter includes the cable that is needed to attach it to the
DSU/CSU.)
The AUX port connector is an 8-position unkeyed modular connector
for the Model 3160 DSU/CSU (Table D-4, AUX Port Connector for Model 3160
DSU/CSUs) and a DB25-type socket connector for Model 3164 and 3165
DSU/CSUs (Table D-5, AUX Port Connector for Model 3164 and 3165
DSU/CSUs).
NOTE:
For daisy-chaining an AUX port to a COM port, an 8-pin-to-8-pin cable
(Model 3160) or 25-pin-to-8-pin cable (Model 3164 or 3165) is required. The
configuration options Com Use and Aux Use must be set to Daisy. Whenever
the cable is connected or disconnected, change the Com Use and Aux Use
configuration options to the correct values.
