1. Check of the NTBA Connection
First the ISDN connection at the NTBA is
checked at normal and at emergency
operation.
means that the NTBA is
connected to the 230 V mains.
means that the NTBA is
connected to the 230 V mains and the
installation is supplied by the Telecom
power supply.
When the
is plugged into the jacks of
the NTBA, the four LEDs light green when
the NTBA is working in normal operation, if
it is running in the emergency mode all
LEDs light red, provided that the NTBA and
the attachment are working correctly.

2. Check of the Wall Outlet Installation
The NTBA has to run in normal operation
and the terminating resistors should not be
mounted when the wall outlet installation
is tested. The
is plugged in one jack
after another (see error chart on the back).
SiTi
4. Test Completion
After completing all tests the terminating
resistors are mounted and the ISDN
installation can be put into operation.
3. Enhanced Check for S -Bus Installation
0
If more than one ISDN device is to run at
one ISDN installation it is important that
wires 2a and 2b are not reversed when
terminated.
In order to exclude reversal of these two
wires, wire 2a is interrupted at the first
possibility of the ISDN installation. Now
the
should show at each wall outlet
the interruption of wire 2a.
If it is showing interruption of wire 2b
this proves that wire 2a and 2b have been
reversed.
When all reversals have been detected and
corrected, wire 2a can be reterminated.
SiTi
The
is a simple device for testing the
installation of an ISDN-S -connection.
Checking of the installation is done by
plugging the
into the RJ45 jack. The
terminating resistors should not yet be
mounted.
The four LEDs of the
show the wiring
diagram of the four terminating wires for
the ISDN-installation.
