Using the Console Port to Remotely Control the XSR

The XSR’s Console port can also be connected to a modem for the purpose of remote console
control. Make the connection with a straight-through cable and enter the following XSR commands:

XSR(config)#interface serial 0
XSR(config-if<S0>)#physical-layer async
XSR(config-if<S0>)#clock rate 9600
XSR(config-if<S0>)#encapsulation ppp
XSR(config-if<S0>)#ip address 192.168.10.1 255.255.255.0
XSR(config-if<S0>)#ppp timeout retry 20
XSR(config-if<S0>)#no shutdown

Set the modem switches as follows:

• DTR override (DTR is ignored)

• No echo offline commands

• Auto answer on first ring

• Carrier Detect normal

• Load factory defaults

• Dumb mode (AT command mode disabled

Connecting a Serial Interface to a Modem

The XSR supports attaching a Serial (RS-232) NIM interface and modem to accept inbound and
outbound data calls. Modem switches and the receiving-side XSR are configured exactly as
described in

“Using the Console Port to Remotely Control the XSR”

except that the

interface

serial 0

command must instead specify

interface serial 1

(or higher). Straight-through

cabling is required again for the connection.

On the calling-side XSR, enter the following commands:

XSR(config)#interface serial 1/1
XSR(config-if<S1/1>)#physical-layer async
XSR(config-if<S1/1>)#clock rate 38400
XSR(config-if<S1/1>)#encapsulation ppp
XSR(config-if<S1/1>)#dialer pool-member 1
XSR(config-if<S1/1>)#no shutdown
XSR(config-if<S1/1>)#dialer interface 1
XSR(config-if<D1>)#dialer pool 1
XSR(config-if<D1>)#dialer string <your phone number>
XSR(config-if<D1>)#address 192.100.10.2 255.255.255.0
XSR(config-if<D1>)#no shutdown

And enter the following calling-side modem switch settings:

• DTR normal (DTR disconnects)

• Echo offline commands

• Verbal result codes

• Display result codes

• Carrier Detect normal

• AT command mode enabled
