Router to WAN
Connection
The Router 5000 provide multiple types of WAN interfaces, and the fixed
WAN interfaces include an AUX port and a WAN interface
(synchronous/asynchronous serial interface). This section describes the
connection of the two interfaces.
Connecting the AUX
port to the Modem
Introduction to the AUX port
As an RS232-compliant asynchronous serial interface, the AUX port can
be used as the backup of other WAN interface in the dial-up mode. In the
event that the console port fails, the AUX port can serve as a console
port. For the attributes of the AUX port, please refer to Table 14.
AUX cable
AUX cable is an 8-core shielded cable. One end of the cable is an RJ45
connector, which can be plugged into the AUX port of the device. The
other end is furnished at the same time with a DB9 (male) connector and
a DB25 (male) connector. The user can choose either of them to plug into
the serial port of Modem as needed.
