  • Page 13 Panasonic offers two PC Console applications for the Attendant position. One is a low-end product (supports up to 96 extensions) and the other is high-end (up to 384 extensions). The PC Console controls the system’s calls from the computer, and the attendant can watch everything on the PC monitor.
  • Page 14    The system must be connected to an input power source of 117V AC (+/-10%), 60 Hz. Each cabinet’s power supply automatically generates 5V DC and 24V DC necessary to power the various printed circuit boards for station and peripheral equipment. Optional backup batteries are available, and are designed to safely fit into the cabinet.

  • Page 18: Cabinets

      Two types of cabinets are used in the DBS 576: the Base cabinet the Expansion cabinet Each cabinet provides 96 universal ports. Systems can be configured with one to six cabinets in a "building-block" fashion. The bottom cabinet in a column is the Base cabinet. The middle and top cabinets in a column must be Expansion cabinets.
  • Page 19 The Base Cabinet Each added Expansion cabinet expands the system capability by an additional 96 ports. One or two Expansion cabinets can be installed on top of a Base cabinet. Up to four Expansion cabinets can be installed in a fully equipped, 6-cabinet system. Multiple slot types are used in the Expansion cabinet.
  • Page 20       The CPC-96 supports a single cabinet (96 ports) and utilizes a 16-bit Central Processor Unit (CPU). Included are the time switch functions (4 highway X 4 highway), 4 DTMF receivers, 8 pairs of conference circuits (3 Member), service tones, DTMF generators, an input terminal for external Music-On-Hold source (RCA jack), connecting terminals for network synchronous package, I/F connector for an external PC card, and a built-in emergency modem (300 bps).
