Product Overview
The Cisco TelePresence
®
ISDN Link is a compact appliance for in-room ISDN and external network connectivity
supporting Cisco TelePresence EX, MX, SX, and C Series endpoints (Figure 1). It provides direct connectivity to
ISDN or external networks (V.35) for individual telepresence endpoints without the need for additional gateways or
other infrastructure (Figure 2). The ISDN Link helps ensure that ISDN can be used as the primary, backup, or
external connectivity for a high-quality and reliable telepresence experience.
