System Requirements

• Minimum 90 MHz PentiumTM5- or the equivalent Celeron^®-based platform with an available PCI bus slot for an 8-port system. The host system must provide a CPU of Pentium or Celeron 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. The computer must run the Windows NT or Windows 20000 operating system.
