3.14. Using the D1029N Adapter (NT1-S only)
Use the D1029 adapter to supply phantom power supply over the S0 BUS in order to
verify the proper working of the terminal equipment (TE) in standard and emergency
mode.

To ensure proper verification, make sure you have disconnected
the TE from the NT1 network termination.

emergency condition.
To choose the desired mode, use the switch located on the side of the D1029.
The two LED’s located on the front panel allow for checking the absorption of the
tested terminal. When the LED’s are off, the terminal absorption over the S BUS is
either null or lower than 3 mW.

The green “NORMAL” LED goes on if absorption is lower than 1100mW when
simulation standard operation, and the red “EMERGENCY” LED goes on if
absorption is lower than 430mW when simulating the emergency operation.

3.15. LT-U Simulation (LT-U2K option)
This option allows for simulating the U interface of a Basic access of an ISDN
exchange and performing call tests from and to an NT1 or NT1+ termination. This
allows for checking the configurations and functions of the socket and connected
devices over the S/T interface and the a/b analog interface for the NT1+.
