Power failure

In the event of a total system power failure, at least 50% of the equipped lines are switched to separate RJ11
connectors on the appropriate MDF. Lines 1 and 2 are power-failed to two RJ11 connectors on the base unit
MDF. Lines 5 and 6 are power-failed to two RJ11 connectors on the first Extension module MDF, lines 9 and 10
to two RJ11 connectors on the second Extension module, lines 13 and 14 to two RJ11 connectors on the third
Extension module and lines 17 and 18 to two RJ11 connectors on the fourth Extension module.
Standard two-wire phones are wired to these connectors and they can make and receive calls when the system is
powered down. The connectors can be wired to separate standard telephones or paralleled with extensions
equipped with standard phones.
ECX 2000 and ECX 1000 digital telephones cannot be used as power failure phones.
All power failure phones must be standard DTMF telephone sets such as the ECX
100 analog telephone.
