After connecting the U connector of the instrument and the U line of the NT socket to
the LT-U ADAPTER, set Basic Access, LT-U mode, on the instrument. The functions
are the same as the NT-S mode.

This mode also allows for making calls from one user terminal to the other one by
simulating a self-call. To do it, go to the “LOOPBOX” menu window and follow the
instructions given in paragraph 3.8.

3.16. S/T-BUS Wiring Test (WT2000 option)
Use an S/T-BUS test to verify the correct installation of the S/T BUS. The instrument
detects polarity inversions, interruptions or short circuits between the bus pairs.
detects polarity inversions, interruptions or short circuits between the bus pairs.
The test must be performed when the ISDN connection is not active. To perform the
test the WT2000 option is necessary. This option consists in two adapters, one
Master (WT2000M) and one Slave (WT-Slave). Connect the WT2000M to the
instrument to the V.11 plug with the corresponding cable. Connect the WT2000M to
the tested bus and close the other bus end with the WT-Slave. Disconnect both the
NT and TE on the BUS, if any.
