Simplified Integration and More
Cisco’s TelePresence ISDN gateway solutions are used when there is more than one endpoint that needs access to a telepresence solution. These gateways offer simplified integration between IP and ISDN networks with complete feature transparency, including high definition (HD) video, content sharing, and encryption.
In addition, an ISDN solution to connect to a single endpoint is now available. The Cisco TelePresence ISDN Link is a compact appliance for in-room ISDN and external network connectivity supporting Cisco TelePresence System endpoints. The ISDN Link helps ensure that ISDN can be used as primary, backup, or external connectivity for a high-quality and reliable telepresence experience.
