MUX EQ, Tx to Customer and Rx from

Customer

The Tx of the BERT is connected to the EQ Tx jack,

and the Rx of the BERT is connected to the Rx EQ

jack (Figure B-7). The Tx of the BERT is then

substituted for the data that the H4TU-C sends to the

Customer. The Rx of the BERT receives data directly

from the Customer. The MON Tx and Rx jacks are

432 ohm impedance copies of the EQ jack Tx and Rx.

This test is intrusive.

NOTE

Via the Test Screen, ensure that the equipment

jack (EQ) is in “To Customer” mode. In “To

Customer” mode, AIS (unframed all ones) is

sent in the Network direction.
