6.2.2.1 CONFIG: MANUAL
MANUAL SELECT:
BRIDGE:02 BACKUP:02
You may manually select which Traffic Modem is to be bridged or backed up. In MANUAL mode
(Auto is OFF), both of these selections are available. Use the
◄ ► arrow keys to first select
between BRIDGE or BACKUP. Then, use the
▲ ▼ arrow keys to scroll through all active Traffic
Modems – the menu skips over any inactive modem slots. Press [ENT] to continue.
In AUTO mode, the Switch has control and will automatically backup any active Traffic Modem
based on its fault relay activity. The BACKUP selection is unavailable for manual selection, but
the modem being bridged may be changed. In this mode, the MANUAL SELECT display appears
as follows:
MANUAL SELECT:
BRIDGE:02 BACKUP:AUTO
Use the
▲ ▼ arrow keys to select an active Traffic Modems – the menu skips over any inactive
modem slots. Press [ENT] to configure.
In BACKUP mode, the Redundant Modem is online. In this case, you may not alter the
bridge/backup state. Instead of the MANUAL SELECT menu, this message displays:
MANUAL SELECT:
SWITCH IS IN AUTO MODE.
Press [CLR] or [ENT] to return to the previous menu.
The Switch learns and retains the configuration of all of the active modems in the setup. The
Switch uses this configuration information to program the Redundant Modem to match the
configuration of the modem being bridged.

OPERATING MODE:
AUTO-OFF AUTO-ON (ENTER)
Use the
◄ ► arrow keys to select AUTO-OFF or AUTO-ON, and then press [ENT].
When off (MANUAL mode), the Switch does not respond automatically to any modem faults and
simply performs whatever manual setting you perform via the previous MANUAL-SELECT menu.
