Introduction1-373610-A2-GB91-90 July 1999Table 1-14TDM Technical SpecificationsSpecifications 1 CriteriaAPPLICATIONMultiplexingDigital sharingFEP port sharingDigital BridgeProvides time division multiplexing of up to two or sixindependent ports, depending on 2-port or 6-port version.Allows two groups of consecutive ports to share the same TDMchannel.Provides up to three separate FEP port-sharing groups.Configured to perform a 5-port digital bridge capability.PORT SYNCHRONOUS RATES 1.2, 2.0, 2.4, 4.0, 4.4, 4.8, 7.2, 8.4, 9.2, 9.6, 12.0, 14.4, 16.8,18.0, 18.8, 19.2, 28.8, 32, 38.4, 48, 56, and 64 kbpsPORT ASYNCHRONOUS RATES 150, 300, 600, 1200, and 1800 bps plus all primary (DSU)rates. Asynchronous rates support +2.3, –2.5 percentoverspeed/underspeed compensation.PORT DTE INTERFACE3610 DSU (2-port TDM) Provides an additional 25-pin D-subminiature connector for atotal of two EIA-232 or V.35 interfaces that can be setindependently when DSU firmware is Release 6.24 or greaterand TDM firmware is Release 5.C or greater.3610 DSU (6-port TDM) Provides five additional 25-pin D-subminiature connectors for atotal of six EIA-232 or V.35 interfaces that can be setindependently of each other when DSU firmware isRelease 6.24 or greater and TDM firmware is Release 5.C orgreater.3610 DSU (TDM/DSD) Provides five additional 25-pin D-subminiature connectors thatcan be optioned for EIA-232 or V.35, for a total of six EIA-232or six V.35 interfaces.3611 DSU (non-modular) Provides one 60-pin high-density D-type connector thatprovides five additional EIA-232 interfaces through an adaptercable.3611 DSU (modular) Provides a 6-port connector module that provides a total of six25-pin D-subminiature EIA-232 connections (including theDSU). In addition, a 26-pin high-density D-type connectorprovides a V.35 interface through an adapter cable.NMS SUPPORT TDM capability is fully supported by COMSPHERE 6700Series NMS, Release 4.0 or greater, or 6800 Series NMS,Release 4.1.5 or greater in ADp and DATAPHONE II modes.1 TDM and MCMP circuit cards can be configured to provide TDM capability.
