NEC 128 manual VisuaLink & ViewPoint VBX Gateway

Application Configurations 2-9

Gateway

The VisuaLink Gateway application configuration allows shared VisuaLink 128/384 units between many users. Existing desktop video/ audio equipment users can now have high quality videoconferencing with VisuaLink. VisuaLink units can be configured in one of two typical gateway applications:

•ViewPoint VBX Gateway

•VisuaLink Direct Connect

Either application configuration allows shared VisuaLink 128/384 units between users. This can be a cost effective solution where existing video/audio equipment is already in place.

VisuaLink & ViewPoint VBX Gateway

A VisuaLink 128/384 unit could be used with a NEC ViewPoint VBX system. The VBX connects all local users, and VisuaLink provides the videoconferencing and interface functions (through the local PBX) to the Telco digital network. VisuaLink is then shared between all users through the VBX. A cost affordable multi-user solution.
