Introduction
This chapter outlines the user interface of the Primary to Basic Rate ISDN Multiplexer and
how the various functions of the Primary to Basic Rate ISDN Multiplexer are set up and
used.
The Primary to Basic Rate ISDN Multiplexer has 2 user interfaces - command line interface
and menu system. The menu system is described here. Details of the command line interface
are provided in the “Command Line Interface” chapter.
The menu system is not available when the Primary to Basic Rate ISDN Multiplexer is being
accessed via Telnet.
The user interfaces operate in 2 modes - user and super. User mode only allows read access to
configuration. Super mode allows read and write access. There is a facility to protect access
to super mode with a password.
Power Up Screen
Assuming that the hardware has been set up as described in the “Installation” chapter, when
power is applied the following message should be displayed on the user terminal or PC
Figure 5 The Primary to Basic Rate ISDN Multiplexer power up display
The default data format is 19200 baud, 8 data bits, 2 stop bits, no parity. If no message
appears then there is probably something wrong with the control cable. If some characters are
displayed but the format is strange then the terminal parameters are probably incorrect. Try
adjusting the terminal parameters so that they match the Primary to Basic Rate ISDN
Multiplexer.
The Primary to Basic Rate ISDN Multiplexer starts with the command line interface and user
mode. Type 'super' <RETURN> to change to supervisor mode.
