BATTERY BACKUP (Memory Protection)
In the event that power is lost to the system, all customer data contained in memory is
backed up by a base board Ni/Cd battery sufficient for at least seven (7) days
continuous loss of system power. When power is restored, the battery will recharge.
BATTERY BACKUP (System)
If an external 24V battery is connected, the system remains fully operational if
AC power is interrupted. Calls in progress are not interrupted when the system
switches over. When AC power is restored, the system recharges the batteries.
Battery maximum size is limited by charging capacity.
CALL FORWARDING
Allows the user to forward incoming calls under various conditions. Calls can be
redirected to the operator group, an external number, or another station or
group. If the destination is in DND, the caller will receive a DND tone. Calls
cannot be forwarded to a door phone.
