GENERAL
Figure B-1 through Figure B-3 are DSX-1 fed modes of
operation, and Figure B-4 through Figure B-7 are MUX
fed modes of operation. From the
Provisioning screen
(Figure 13), select “
8” to choose the Network Source as
MUX fed or DSX fed. When performing intrusive MUX
mode testing, the equipment jack on the front panel can
be configured to access the signal going to the Network
or the Customer. Select “
6” from the Tes t screen (Figure
17) to configure the equipment jack for Network or
Customer. Every time the HTUC is power-cycled, it
will default to the Customer direction.
DSX MODE TEST ACCESS
DSX MON, TX to Customer
The RX of the BERT receives data from the
TX MON
jack (Figure B-1). This data has a monitor jack
impedance of 432 ohms and comes from the Backplane
Network T1 DSX (the data that would go toward the
customer). The
BERT TX is not used. This test is non-
intrusive.
NOTE
The H2TU-C must be provisioned for the
Out
of Service–Maintenance
Service State when
intrusive bantam jack testing is being
performed.
Figure B-1. DSX MON, TX to Customer
DSX MON, RX from Customer
The RX of the BERT receives data from the
RX MON
jack (Figure B-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.
Figure B-2. DSX MON, RX from Customer
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 B-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.
