Use the ◄ ► arrow keys to select which Traffic Modem to activate, and then use the ▲ ▼
arrow keys to activate or deactivate the modem.
A modem must be active in order for it to be available for bridge or backup. A hyphen (-)
appears in place of the modem number if it is deactivated. If a Traffic Modem interface is not
plugged into a slot, that position cannot be activated.
Once activated, the Switch expects that modem to be connected, and it polls the modem for
status information.
When adding or removing a modem in an operating 1:N Switch system, it is important to keep
the traffic safe, by preventing any contention in the system from an unsuppressed modem Tx
carrier.
