RAD Gets Patent for TDM

TEL AVIV -- The United States Patent and Trademark Office has granted a patent to RAD Data Communications for TDM over Internet Protocol (TDMoIPR) technology.

U.S. patent 6,731,649 describes a method for transporting one or more TDM links over packet switched IP networks. A TDMoIP gateway encapsulates segments of the constant rate TDM in AAL1 cells, which are carried in UDP/IP packets. A second TDMoIP gateway at the destination regenerates the clock, strips the UDP/IP headers and delivers a synchronous bit stream. This solution also provides an adaptive clock for clock transfer across the entire network.

Carrier and enterprise markets alike use TDMoIP technology to provide connectivity for enterprise PBXs and data equipment over private and public packet networks, service provider circuit emulation services, cellular backhaul, SS7 transport, disaster recovery and other voice, video and data/telemetry applications.
