Configuration Option TablesA-97610-A2-GB20-00 November 1996Data Port Options MenuFor Data Port Options, refer to Table A-3. To access the Data Port Optionsscreen, follow this menu selection sequence:Main Menu →Configuration →Load Configuration From →Edit →Data PortTable A-3. Data Port Options (1 of 3)Invert Transmit ClockPossible Settings: Enable, DisableDefault Setting: DisableThe DSU clock provided on Interchange Circuit CT114, Transmit Signal Element TimingDCE source (TXC), is phase inverted with respect to Interchange Circuit CT103,Transmitted Data (TXD). Recommended when data errors are occurring due to longcable lengths.Enable – The DSU-supplied clock is phase inverted with respect to the transmitted dataTXD.Disable – The clock supplied by the DSU on TXC is normal (i.e., not inverted).Port (DTE) Initiated LoopbacksPossible Settings: Disable, Local, Remote, BothDefault Setting: DisableSpecifies whether the DTE can initiate and terminate local and/or remote loopbacks.The DTE loopback control is done through the Interchange Circuits specified by theV.54 standard.NOTE: Refer to theLoopbacks section of Chapter 7.Disable – No local or remote loopbacks can be initiated by the DTE.Local – A local loopback can be controlled by the DTE, via the Interchange Circuit LL(CT141), as specified by V.54. The DTE port remains in loopback as along as LLremains on. Aborting the loopback from the ATI has no effect.Remote – A remote digital loopback can be controlled by the DTE, via InterchangeCircuit RL (CT140), as specified by V.54. The remote equipment must be able to detectthe in-band V.54 loopback sequence.Both – Both the local and remote loopbacks can be controlled by the DTE.Bilateral LoopbackPossible Settings: Enable, DisableDefault Setting: DisableWhen a DSU loopback is initiated, a local DTE loopback is also automatically initiated.A Bilateral Loopback can be started by the ATI/NMS or by detection of a V.54 Loop 2 Upsequence.Enable – When Bilateral Loopback is enabled, running a DSU loopback alsoautomatically starts a local loopback. The local loopback ends when the DSU loopbackterminates.Disable – Running a DSU loopback does not start a local loopback.NOTE: Refer to theLoopbacks and theNetwork Tests sections of Chapter 7.
