With a single HDSL Installation Kit and T1 BERT
tester, a loopback test of the cable span can be
performed from the central office end or from the
remote end. With CO and Remote HDSL Installation
Kits and two BERT testers, an end-to-end test of the
entire cable span can be performed. The directions for
performing the BERT test are as follows.
1. Install test cables to make the following
connections between the T1 BERT tester and the
HTU-C installed in the HDSL Installation Kit.
For an end-to-end test, make the connections at
both ends of the cable span.
• Connect the BERT tester's DSX-1 RX jack to
the DS1 line receive jack on the front panel of
the HTU-C or HTU-R
• Connect the BERT testers DSX-1 TX jack to
the DS1 line transmit jack on the front panel
of the HTU-C or HTU-R.
NOTE
As an alternative to the DS1 signal jacks, use
the DS1 RX and TX jacks located just above
the line unit slot on the HDSL Installation
Kit. These jacks correspond to line unit
operation, which means that the BERT
tester's DS1 transmit jack must be connected
to the Installation Kit's DS1 TX jack, and the
tester's DS1 receive jack to the Installation
Kit's DS1 RX jack.
2. Install a test cable to connect the HDSL
Installation Kit to the HDSL circuit. For and
end-to-end test, make the connections at both
ends of the cable span.
• Connect the HDSL Installation Kit's LP1
signal jack to the loop 1 twisted pair.
• Connect the HDSL Installation Kit's LP2
signal jack to the loop 2 twisted pair.
3. If a loopback BERT test is being performed, loop
back the far end.
4. Turn ON the HDSL Installation Kit and T1
BERT tester. If an end-to end test is being run,
turn on both Installation Kits and testers.
5. Run a T1 BERT test over the HDSL cable span.
