polarity inversions or short circuits between the bus pairs.
The test must be performed when the ISDN connection is not active. The WT2001
option is required to perform the test. The option consists in two adapters, a Master
(WT2001M) and a Slave (WT2001S) adapter. Connect the WT2001M to the D2001
to the auxiliary connector via cable AUX. Connect the WT2001M to the tested bus
and close the other end of the bus with the WT2001S. Disconnect the NT and the
bus TE’s, if present.
