AUX Port Interface
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).

NOTE
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.
