Model 3610 Installation2-93610-A2-GB91-90 July 1999Async Terminal ConnectionAn async terminal can only be connected to aModel 3610 DSU. The DSU CC-to-DB25 cable (featurenumber 3600-F3-504) is required. Refer to Figure 2-5 asyou connect the DSU to an async terminal. Procedure1. Plug the 4-pin modular plug of the DSUCC-to-DB25 cable into the DSU jack labeledCC/DC.2. Connect the EIA-232 (DB25) end of the cable tothe async terminal.3. Tighten the holding screws.Figure 2-5. Model 3610 DSU Async TerminalSoftware ConfigurationThe Model 3610 is configured at the factory as atributary set to operate at 9.6 kbps. (Factory-setconfiguration options are referred to as default settings inthis guide.)Software configurations can be changed from the DCP,an async terminal if the unit is a Model 3610 DSU, or anNMS that supports this feature.From the DCP and Async TerminalYou can change configuration options using an asyncterminal if you have a Model 3610 (standalone) DSU withfirmware version (DSU SW ver) 6.3x or greater. Once anasync terminal session is active, changing configurationoptions follow the same steps as when using the DCP.Refer to Appendix D for async terminal operationinformation.To change configuration options of the Model 3610(or 3611) DSU from the DCP or of the Model 3610 froman async terminal, select the Local branch and then theConfiguration (Confg) branch. (If not displayed, press thekey until Confg is displayed, then press the functionkey below the selection.) Select Opts (for ConfigurationOptions), then Load.The following selections are available: Activ, Remt,Usr1, Usr2, Usr3, FacC, FacT, and FacB. If the desiredselection is not displayed, press the key until thedesired configuration option set is displayed, then pressthe function key under the displayed selection. Refer toChapter 6 for additional configuration information.From the NMSA Model 3610 (or 3611 DSU) can also be set from a6800 Series NMS using the Change commands (for the6700 Series NMS, select Config→NetWork→Services→the appropriate submenu selection). These 6800commands include the following:• cho followed by the DSU’s network address allowsyou to change the DSU, Diagnostic (DSU, DBM,and General), General, and LPDA configurationoption sets.• cho followed by the DBM’s network address allowsyou to change the DBM, Backup, Diagnostic (DSU,DBM, and General), and General configurationoption sets.• cha followed by the DSU’s serial number allowsyou to change the tributary DSU’s network address.When configuration options are changed through anNMS routine, a Display command should be executed(i.e., dso) to verify that the Change command wassuccessful.
