DSX MON, Rx from Customer

The Rx of the BERT receives data from the RX MON jack (Figure A-2). This data has a monitor

jack impedance of 432 ohms and comes from the customer-originated data. The

BERT TX jack

is not used. This test is non-intrusive.

DSX EQ, Tx to Customer, Rx from Customer

The Tx of the BERT goes to the TX EQ jack, and the Rx of the BERT goes to the RX EQ jack

(Figure A-3). The

TX EQ data from the BERT is sent to the customer. The RX EQ data to the

BERT is data from the customer. The

MON jack TX and RX are 432 ohm replicas of the EQ TX

and

RX direct connections. This test is intrusive, as it connects the EQ jacks directly to and

from the customer data.
