communication system using the Pulse Code Modulation (PCM) technique. The
system is comprised of central equipment cabinets and telephones located throughout
the installation site. The central equipment cabinet is composed of Port Interface
Modules (PIMs). One to Eight PIMs may be installed, depending on the requirements
of the individual customer. The PIMs are designed for modular growth, stack
mounting (4 PIMs high), and quick interconnection. Each PIM provides 64 ports. The
universal port design minimizes the hardware required for a system, and provides
greater flexibility in the number and types of devices that can be installed.
