Administrative connections
Figure 5-3. Backup administrative connection with a modem to the Stinger unit
The modem you use to connect to the Stinger unit must be configured as follows:
■
Dumb mode. Dumb mode causes the modem to ignore data on the receive data
(RD) lead.
■
Ignore on-to-off transitions of the data-terminal ready (DTR) lead.
■
Auto answer enabled.
■
8 bits, 1 stop bit, and no parity.
■
9600bps (38400bps for the IP2100 IP control module)
Configure the following AT commands on the modem:
Modem country codes
You can configure the internal modem in a revision 2 control module to support the
national regulations of telephone companies in specific countries. If the modem
supports the country that you have specified, the system programs the modem with
the settings necessary for that country. The
country-code
parameter in the
modem
profile, shown here with its default value, is used for this setting.
[in MODEM/{ shelf-1 first-control-module 3 }]

country-code = unitedstates
The

that is currently configured in the modem.
