The CDM-750 and CDM-760 Advanced High-Speed Trunking Modems automatically detect if
they are connected to a 1:1 redundancy system.
Typical for either product, with both modems automatically configured for 1:1 operation, the
online modem keeps the offline modem updated as online modem configuration changes
occur.
You can also manually 'force' backup of the online modem. Use the modem front panel to
select the Utility 1:1 screen:
Press ENTER key to force Unit into
Standby (1:1 only)
If the unit is part of a 1:1 redundant pair and this unit is currently online, press ENTER to force
the current unit to switch to standby mode.
