The M6501L IP PBX consists of one or two cabinets. The basic cabinet with the standard OCT4
card is connected to the expansion cabinet, equipped with an ROCT3B card, via an external
cable. Each cabinet has its own power-supply module (ADS 300).
To ensure continuity of service, the M6501L IP PBX must be backed up by sealed maintenance-
free batteries for which the only operating state is floating mode, maintaining the load voltage of
the components at 2.27
V.
