Management from a

Terminal

The configuration of Vmux-2100 is performed via menu-driven embedded software, using a standard ASCII terminal or a PC running a terminal emulation application connected to the rear panel CONTROL port. Alternatively, you can configure Vmux-2100 via Telnet connection, which also establishes an inband management link to the remote unit.

4.1 Preparing for the Control Session

This section describes how to prepare Vmux-2100 and the supervisory terminal for the control session.

Control Port Interface Characteristics

Vmux-2100 includes a V.24/RS-232 asynchronous DCE port, designated CONTROL and terminated in a 9-pin D-type female connector. The control port continuously monitors the incoming data stream and immediately responds to any input string received through this port.

The terminal can be connected either directly to the Vmux-2100 control port, or through a modem or any other type of full-duplex data link.

•Direct connection to terminals. Since terminals usually have DTE interfaces, the connection to the port is made by means of a straight cable.

•Connection through a modem or data link. In this case, you need a cross cable (RAD’s CBL-VMUX-MM-MODEM) to connect to the CONTROL connector (see Appendix A for the cross cable wiring diagram).

Preparing the Terminal

Any standard ASCII terminal (a “dumb” terminal or a personal computer running

aterminal emulation application) equipped with a V.24/RS-232 communication interface can be used to configure Vmux-2100. Appendix A details the pin assignment and control signal directions of the Vmux-2100 control connector.

Data Terminal Ready (DTR)

When connected and turned on, the terminal sets the DTR line ON (active) to gain control over Vmux-2100 and starts a configuration or monitoring session.
