AUX Port Interface

The Auxiliary (AUX) port connects to the LAN Adapter for SNMP or Telnet applications, or to another DSU/CSU’s 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.
