Dsx Mon, Rx From Customer; Dsx Eq, Tx To Customer, Rx From Customer - ADTRAN 1181113L2 Installation And Maintenance Practice

DSX Mode Test Access HDSL2 for General Distribution Installation and Maintenance Practice
DSX MON, Rx from Customer
The Rx of the BERT receives data from the RX MON jack (Figure C-2). This data has a monitor
jack impedance of 432 ohms and comes from the customer originated data. The BERT TX 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 C-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.
