Introduction1-2 3160-A2-GB21-80March 1999 Integral modem for standalone DSU/CSUs. Asynchronous (async) terminal interface support. Telnet access for remote async terminal operations. Network management provided through industry-standard Simple NetworkManagement Protocol (SNMP).DTE Drop/Insert (DSX-1) InterfaceThe DTE Drop/Insert interface allows DTEs/PBXs that support the DS1 signalformat to share the T1 network with other high-speed equipment. This is availableon 2-port and 4-port DSU/CSUs.Alarm Message CapabilityThe DSU/CSU can be attached, either locally or remotely, to an ASCII terminal orprinter to display or print alarm messages. Alarms can also be displayed on a PCthat is using a terminal emulation package.Front Panel EmulationThe DSU/CSU offers functionality through Front Panel Emulation software that issimilar to that provided by the DSU/CSU front panel. The functionality of the frontpanel is available by clicking on the function keys with the mouse rather than bypressing keys from the actual front panel.Integral ModemThe standalone DSU/CSUs contain an integral low-speed (2400 bps), V.22bisdial modem that enables communication with remote devices such as another316x DSU/CSU, an ASCII terminal or printer, or a PC running the 3100 SeriesFront Panel Emulation software.Async Terminal Interface SupportThe DSU/CSU can be configured and managed from an asynchronous (async)terminal. The async terminal’s full screen display uses a menu hierarchy similarto the DSU/CSU’s front panel. You can perform device management andconfiguration operations as if you are using the DSU/CSU’s front panel, but youdo not have the limitation of the 2-line, 16-character LCD.Telnet AccessRemote async terminal operations can be performed using Telnet access. Telnetis a Transmission Control Protocol/Internet Protocol (TCP/IP) service thatsupports a virtual terminal interface.
