670118 NEC NEC Univerge SV8100/SV9100 PBX Expansion Card

The NEC 670118 CD-PRTA is a single-port Primary Rate Interface (PRI) card designed for NEC Univerge telephone systems. This telecommunications card provides ISDN PRI connectivity, enabling up to 30 simultaneous voice channels (E1 standard) for trunk connections between the PBX and the public switched telephone network or private tie lines.

The CD-PRTA card is intended for installation in NEC Univerge SV8100 and SV9100 communication servers, serving as the interface for high-capacity digital trunk lines. It is typically deployed in medium to large business environments where significant call volumes require robust, reliable PRI connectivity.

This is a legacy product associated with NEC’s established Univerge platform. While PRI technology continues to serve many enterprise telephony installations, organisations should consider this card for maintaining or expanding existing NEC Univerge deployments where ISDN infrastructure remains in use.
