ISDN Status LEDs
Three red LED indicators are mounted on the ATS7120/7121
ISDN PCB. The indicators give the installer information about
the current line status, call progress, and possible errors.
During normal operation, the indicators are either on, off,
blinking, or flashing. Blinking means 1 second on, 1 second off
and so on. Flashing means 0.1 seconds on and 0.9 seconds
off.
When the indicators are blinking in sequence after each other,
at a time interval of 0.5 seconds, a hardware error is present
and the ATS7120/7121 is in factory diagnostics mode.

S0 Mon LED
The S0 Mon LED is on when the ATS7121 is transmitting
events via the ISDN D-Channel. During this (short)
transmission the S0 Monitor serial port is temporary switched
off. All data is buffered and will be displayed when the port is
available again.

Country dependent settings:
The X.25 TEI Value and X.25 D-Bit value are country
dependent, and are explained in chapters
“General” on page 2
and “ATS7121” on page 3. The phone number will be provided
by the Central Station. This will be a number that gives access
to the X.25 network. In the Netherlands, these numbers start
with the digits 0204, in Belgium with 1206. The system and
area account numbers are provided by the Central Station.
