The Atlas 830 Dual Video Module is the newest addition to the Atlas video switching option modules designed to support videoconferencing applications. The Dual Video Module provides two sets of RS-366 interfaces and synchronous DTE ports to add inverse multiplexing (IMUX) function in Atlas. The DTE ports support V.35, RS-449, and EIA-530 interfaces. The Dual Video Module can be used in conjunction with the Atlas 830 PRI/T1, BONDing and multi-port BRI modules to provide industry-leading video-conferencing network access and video switching over ISDN services. By centrally locating the Atlas Integrated Access Device (IAD), users can connect video systems from different floors in a building or from multiple buildings within a campus. This allows each system to share service provider network access on a call-by-call basis. Dedicated videoconferencing access circuits can be eliminated, which reduces monthly costs.The Dual Video Module combined with the BONDing module enables users to create high-bandwidth video sessions. Each video port supports Nx56/64K access up to a maximum 1.472 Mbps. Integrating the BONDing and Inverse Multiplexing into the Atlas multi-function platform offers low cost, high performance, and simplicity advantages over external inverse multiplexers. The dial menu will allow storage for up to 10 numbers and includes the number, a text description, the call type, the source ID, and the minimum and maximum number of DS0s. Dialing options include manual, DTR dialing, and RS-366 dialing.
