Data Sheet
Cisco TelePresence Serial GW 3340
Product Overview
The Cisco TelePresence®Serial GW 3340 is part of the industry-leading Cisco TelePresence videoconferencing
solution. It allows transparent integration between IP and serial videoconferencing networks (Figure 1). A easy to
configure appliance with feature transparency plus powerful dial-plan capabilities, it allows organizations using
networks attached through serial interfaces to gain all the benefits from IP-based high-definition (HD)
videoconferencing solutions.
