DSU/CSUs FEATURE BUILT-IN TESTINGMONITOR AND MANAGE frame relay links without the expense of dedicated test equipment and analyzers with the FramePath Dsu/CSUs from Larscom. Designed for the particular needs of service providers who offer frame relay applications, the FramePath 64 DDS (1) (Digital Data Storage) See DAT. (2) (Data Dictionary System) See QuickBuild and OpenDDS. (3) (Dataphone Digital S Frame Relay DSU and the FramePath 100 T1/FT1 Frame Relay DSU/CSU (Digital (or Data) Service Unit/Channel Service Unit) A pair of communications devices that connect an inhouse line to an external digital circuit (T1, DDS, etc.). incorporate in-band SNMP management, end-to-end performance monitoring, dialed management connections, alarm dial-out, and ISDN-based backup and bandwidth-on-demand options. Individual, full-time performance registers track problems at the line and frame relay levels - even measuring private virtual circuit (PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. ) quality-of-service parameters such as network transit delays, lost frames, and congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. . Probe and test set features include a bit error rate tester (BERT (Bit Error Rate Test) An analysis of network transmission efficiency that computes the percentage of bits received in error from the total number sent. ). An integrated modem with automatic backup provides built-in modem line sharing for up to two other pieces of equipment (router and PBX), eliminating the need for external modems and the cost of an additional leased line. - Larscom Inc. |
