System Requirements
• Minimum 90 MHz Pentium processor or the equivalent Celeron processor
with an available PCI bus slot for an 8-port system. The host system must
provide a CPU of Pentium processor or Celeron processor class at 266 MHz
speed or higher for a 64-port system, including eight available PCI slots. The
PBX Integration Board occupies a single expansion slot, and up to eight
boards can be configured in a system, with each board sharing the same
interrupt level. The maximum number of ports supported is 64, dependent on
the application, the amount of disk I/O required, and the host computer’s
CPU.
