1.6.2 V.24 interface (external management)
The V.24 interface is an RJ11 socket.
At the V.24 connection, a serial interface is provided for the local connection
of an external management station (VT100 terminal or PC with
corresponding terminal emulation) or an AutoConfiguration Adapter ACA 11.
This enables you to set up a connection to the Command Line Interface (CLI)
and to the system monitor.
The socket housing is electrically connected to the front panel of the device.
The V.24 interface is electrically insulated from the supply voltage.
