About the 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.
