PG-FLEX REMOTE TERMINAL
LINE UNIT STREAKER CARD
QUICK REFERENCE GUIDE
The PairGain®PG-Flex™ FSU-796 List 6 Remote Terminal Line Unit (RTLU) Streaker card is a continuity
tester. The card verifiesthat the HDSL, Auxiliary Power, and Bypass Pair terminations from the RT line unit slot
of a PG-Flex RT enclosure are wired to the termination point correctly.
When you receive the PG-Flex FSU-796 List 6 Streaker card:
1Unpack the PG-Flex FSU-796 Streaker card and visually inspect
it for signs of damage. If the components have been damaged in
transit, immediately report the extent of damage to the
transportation company and to your sales representative. Order a
replacement unit if necessary.
2Compare the contents of the package against the packing list. If
the shipment is incorrect, contact PairGain as described in the
"Limited Warranty" section.
The illustration shows the FSU-796 List 6 front panel, and the
table below describes the features and functions for the front

Use the following procedure to verify the wiring between an FRE-756 RT enclosure and the termination point.
1At the cable stub termination, connect a jumper lead from frame ground to the appropriate termination from
the RT enclosure. Verify that the corresponding LED on the FSU-796 is on. (Refer to Table 1 for the HDSL,
Auxiliary Power, and Bypass Pair wire pair colors for the Lists 4D and 4E.)
• If the correct LED lights, proceed to the next connector termination.
• If the LED under test does not light, check that the wiring to the RT enclosure.
• If the opposite or wrong LED lights, check for reversed wiring.
2Repeat the previous step for each line unit termination.
Power should not be applied to the FRE-765 RT enclosure while verifying the wiring.
