Operation; Figure 2. Hdsl Circuit Simulation - ADTRAN HDSL 851 Installation And Maintenance Manual

NOTE
The installation kit and adapter insert described
here is not compatible with previous kit and
adapter assemblies.
Description
The HDSL Remote Installation Kit simulates the
operation of the remote end of an HDSL circuit with
an installed remote line unit.
Make-or-break jacks and signal jacks in each
installation kit provide access to the HDSL circuit's
loop 1 and loop 2 signals. Inserting a test cable into a
jack breaks the HDSL circuit at that point and delivers
the signal out of the jack. The jacks can be used to
insert an HDSL installation kit into an HDSL circuit at
different points such as the central office end or
remote end in order to test circuit or line unit

operation.

The jacks can also be used to connect HDSL
installation kits together to simulate an HDSL circuit's
signal path. A fully operational HDSL circuit can be
created by connecting a CO installation kit to a remote
installation kit and installing HDSL line units. See
Figure 2 for a diagram of an HDSL circuit simulation.
To simulate an HDSL circuit with a repeater, push IN
the repeater selection switch on the remote unit.

2. OPERATION
After unpacking the unit, inspect it for damage. If
damage is noted, file a claim with the carrier, then
notify ADTRAN. See Warranty and Customer
Service.
The Remote Installation Kit is shipped complete with
remote shelf and dual bantam to alligator cables.
Front Panel Features
The HDSL Remote Installation Kit front panel
features remote and repeater unit slots, four dual-
bantam jacks, a repeater selection button, and two
ground lugs for ESD ground and earth ground.
The remote unit slot accepts an HDSL remote line
unit. The repeater unit slot accepts a repeater line
unit. The repeater selection button controls whether
the repeater installed in the remote installation kit is
inserted into the HDSL circuit. When the button is
pressed IN, the repeater is inserted into the HDSL
circuit. When the button is placed OUT, the repeater
is removed from the HDSL circuit.
There are four dual-bantam jacks on the front panel.
The Repeater CO-side LP1/LP2 signal jacks provide
access to the repeater's CO-side loop 1 and loop 2
signals. The repeater remote-side LP1/LP2 signal
jacks provide access to the repeater's remote-side loop
1 and loop 2 signals.
