•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.
