Changing the Asynchronous Baud Rate
When the
wan-type
parameter is set to asynchronous, the asynchronous baud rate
determines the transmission speed between the modem and the serial interface.
When setting this parameter, select a value that is greater than or equal to the
speed of the modem. The default is 115,200 b/s.
To set the asynchronous baud rate using the BCC, navigate to the modem prompt
and enter:
async-baud-rate
<rate>
rate
can be:
For example:
modem/1/1#
async-baud-rate 28800b
To configure the asynchronous baud rate using Site Manager, see Configuring
WAN Lines Services.
Using Modem Factory Defaults
For the ARN
using the V.34 Modem Adapter module
, you can specify whether
exclusive use of the factory default modem initialization string is enabled or
disabled. When the factory default string is enabled, the router sends only the
default string
(AT&d0&k3&X0S0=2S2=43) to the m
odem. When disabled, the
router sends a user-specified initialization string after sending the default string.
Set the user-specified string in the Modem Config String parameter (Site
Manager) or in the modem-init string (BCC). Commands in the user-specified
string take precedence over the factory default command string.
