MUX MODE TEST ACCESS

MUX Mode tests through a MUX on the Total Access 3000 shelf.

MUX MON, Tx to Customer

The Rx of the BERT receives data from the TX MON EQ jack (Figure C-4). This data is a copy of

the data that the H2TU-C will transmit to the customer. The Tx of the BERT is not used. This

test is non-intrusive.
