DSX MON, Rx from Customer

The Rx of the BERT receives data from the
jack impedance of 432 ohms and comes from the customer originated data. The
used. This test is non-intrusive.
T1 BERT

DSX EQ, Tx to Customer, Rx from Customer

The Tx of the BERT goes to the
(Figure C-3). The
TX EQ
BERT is data from the customer. The
and direct connections. This test is intrusive, as it connects the
RX
from the customer data.
