inserted into the HDSL circuit. When the button is
pressed IN, the repeater is inserted into the HDSL
circuit. When the button is popped 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. The Remote LP1/LP2 Signal
jacks provide access to the HDSL circuit's loop 1 and
loop 2 signals coming from the central office end.
The DS1 TX and RX Signal jacks provide access to
the DS1 signals on a remote line unit installed in the
remote unit slot. These jacks are used when the line
unit front panel does not have jacks for accessing the
DS1 signals. TX is an input jack and RX is an output
jack. See Figure 3 for front panel features.
Powering the HDSL Remote Installation Kit
The ADTRAN HDSL Remote Installation Kit can be
powered by installing cables between its LP1/LP2
signal jacks and the LP1/LP2 signal jacks on the
Central Office Installation Kit. See the documentation
for the HDSL CO Installation Kit (part number
1190852L1) for directions on powering the CO
