MUX EQ, Tx to Customer, Rx from Customer

The Tx of the BERT is connected to the
jack (Figure C-7). The Tx of the BERT is then substituted for the data that the H2TU-C
RX EQ
sends to the customer. The Rx of the BERT receives data directly from the customer. The
and jacks are 432 ohm impedance copies of the
TX RX
intrusive. Via the
Test
the mode, AIS (unframed all 1's) is sent in the network direction.
