Page 14 of 162 Communicating with the system553-3041-500 Standard 1.00 September 2004System terminal access for CS 1000ETerminal ServerBecause each CS 1000E Core Call Server provides only two ports for serialdevices, the Terminal Server is used to provide the necessary standard serialports for the applications and devices that require them (for example, forprinters and Call Detail Recording [CDR]). The Terminal Server is also usedto connect maintenance terminals and modems for support staff.The Terminal Server provides an rlogin service that allows serial devices toestablish dedicated connections to pseudo TTY (PTY) ports on the CallServer. (The Terminal Server therefore serves the same purpose as SerialData Interface [SDI] and Multi-purpose Serial Data Link [MSDL] cards inLarge Systems.) It is possible to telnet through the Terminal Server toindividual components on the ELAN subnet, and therefore obtainmaintenance access for each device. Users can also access the TerminalServer from a remote PC by dialing the on-board modem.As the Terminal Server is configured to automatically log in to the active CallServer upon startup, only one Terminal Server is required for each Call Serverpair.Note: While the Terminal Server is required to provide serial port accessto the Call Server, it can also be optionally configured to provide accessto Media Gateway 1000T (MG 1000T) serial ports for maintenancepurposes.For more details on installing and configuring the Terminal Server, seeCommunication Server 1000E: Installation and Configuration(553-3041-210).System terminalWhen a system terminal is installed locally, it is typically connected to a serialport on the Terminal Server. This ensures continued access to the active CallServer. When a system terminal is installed at a remote location, a modem anda telephone line are required between the system terminal and the TerminalServer.
