Adapter Overview

The iSPAN™ PRI (Primary Rate Interface) adapter is a Peripheral Component (PCI) add-on board for PCI-based PCs, servers, and workstations. It enables systems to connect to one or two ISDN primary rate interfaces.

The single-PRI version is powered by the IBM® PowerPC403GA 32-bit RISC processor at 33 MHz.

The dual-PRI version is powered by the IBM PowerPC 403GCX 32-bit RISC processor at 66 MHz, and combined with a 32-bit/33-MHz PCI interface. It provides a fast pathway to enterprise communication server applications.
