Configuring and using dial-in connections
You may attach an external modem to the console port for dial-in serial CLI access to the CCM
appliance. This may be used as a backup connection if the unit is not accessible from the network.
It may also be used as a primary connection at remote sites that do not have Ethernet network
capability. The modem must be Hayes compatible.
To specify a modem initialization string:
1. Issue a Server CLI command, using the Modeminit parameter to specify the modem initializa-
tion string.
SERVER CLI MODEMINIT=“<string>”
The string must be enclosed in quotes and must include at least the command settings ATV1
and SO=1, which cause the modem to issue verbose response strings and autoanswer the phone
on the first ring. For more information, see Server CLI command on page 49.
The modem initialization string is sent to the cabled modem when any of the following
conditions occur:
•
CCM appliance initialization
•
Detection of a transition of DSR from low to high
•
Completion of a call when DCD changes from high to low
2. Upon successful modem connection, press the
Enter
key until the login prompt appears.
To display modem configuration information:
Issue a Show Server CLI command.
SHOW SERVER CLI
