Panasonics VB-2089P supplies ringing voltage for up to 4 analog station cards for the DBS40, 72, and 96 port systems. This unit is wall mountable and is wired to the connector panel. In a double cabinet system, this unit needs to be attached to the cabinet that contains the analog station cards. If both cabinets have analog stations, then both cabinets require a ringer box.
