MUX EQ, TX to Customer, 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 H2TU-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
Tes t screen, ensure that the equipment
jack is in “
To Customer” mode. In “To
Customer
” mode, AIS (unframed all 1’s) is
sent in the Network direction.
