About Cisco Unified Videoconferencing 3545 Gateway Products
Cisco Unified Videoconferencing 3545 Gateway series consists of these products:
• Cisco Unified Videoconferencing 3545 PRI Gateway
The Cisco Unified Videoconferencing 3545 PRI Gateway enables audio, video, and data
communication between H.320 endpoints that connect through ISDN, and H.323 endpoints that
connect through a packet-based network. For voice-over-IP, the gateway enables PSTN voice
callers to connect from the ISDN network to IP voice callers. The Cisco Unified Videoconferencing
3545 PRI Gateway supports two PRI ISDN ports.
• Cisco Unified Videoconferencing 3545 Serial Gateway
The Cisco Unified Videoconferencing 3545 Serial Gateway supports multimedia conferencing over
IP by translating between H.323 and serial protocols. With the help of a V.35 Adtran Imux, the
gateway can also translate between H.323 and H.320 protocols.
The gateway offers a serial leg for multimedia conferencing over IP by providing an interface for
legacy endpoints with serial interfaces, encryption/decryption devices, satellite networks and leased
line services.
