USB interface
The USB socket provides an interface for the local connection of an Auto-
Configuration Adapter. It is used for saving/loading the configuration and
for loading the software.
V.24 interface (external management)
A serial interface is provided on the RJ11 socket (V.24 interface) for the
local connection of an external management station (VT100 terminal or
PC with appropriate terminal emulation) or an AutoConfiguration Adapter
ACA 11. This enables a connection to the Command Line Interface (CLI)
and the system monitor to be made.
The socket housing is electrically connected to the front panel of the
device. The V24 interface is not electrically isolated from the supply
voltage.
