AUX Port Interface

NOTE

The Auxiliary (AUX) port connects to the SNMP LAN Adapter for SNMP applications, or to another E1 NTU's COM port for daisy chain connectivity. (The SNMP LAN

Adapter includes the cable that is needed to attach it to the E1 NTU.) The AUX port connector is an 8-pin modular connector (Table D-3).

For daisy-chaining an AUX port to a COM port, a customer supplied, 8-pin-to-8-pin, straight- through cable is required and the appropriate configuration options (Com Use and Aux Use) must be set to Daisy. Whenever the cable is connected or disconnected, you should change the Daisy selection to ensure that the correct parameters have been negotiated for the link layer.
