Front Panel DSX and MUX Mode Test Access

GENERAL

Figure C-1 through Figure C-3
Figure C-7 are MUX fed modes of operation. From the Provisioning menu
page 22), the Network Source option is used to choose either
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. The Equipment Jack
option on the Loopback and Test Commands screen
,
used to configure the equipment jack for the network or customer. Every time the HTU-C is
power-cycled, it will default to the Customer direction.

DSX MODE TEST ACCESS

DSX Mode connects to the DSX (network) connector on the backplane of the chassis, where a
Multiplexer (MUX) is not utilized in the Total Access 3000 shelf.

DSX MON, Tx to Customer

The Rx of the BERT receives data from the
jack impedance of 432 ohms and comes from the Backplane Network T1 DSX (the data that
would go toward the customer). The
The H2TU-C must be provisioned for the Out-of-Service Mainte-
nance service state when intrusive bantam jack testing is being
performed.
