PG-FLEX REMOTE TERMINAL
CHANNEL UNIT STREAKER CARD
QUICK REFERENCE GUIDE
This PairGain®PG-Flex™ FSU-796 List 5 Remote Terminal Channel Unit (RTCU) Streaker card is a continuity
tester. The card verifies that the Tip and Ring connections from the channel unit slots of a PG-Flex RT enclosure
are wired to the termination point correctly, and that the RT line unit is providing the required power supply
voltages to the channel units.
When you receive the PG-Flex FSU-796 List 5 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 5 front panel, and the table describes
the features and functions for the front panel LEDs and the LED Test switch.
MODEL FSU-796 LIST 5, P/N150-1396-05
Feature Function
Tip 1 - 8
LEDs
(T1 - T8)
Lights when one of the Tip subscriber terminations
(T1 - T8) is shorted to ground.
If the LED for the termination under test does not light,
the termination is miswired.
If the corresponding Ring LED lights, the subscriber
termination is reversed.
Ring 1 - 8
LEDs
(R1 - R8)
Lights when one of the Ring subscriber terminations
(R1 - R8) is shorted to ground.
If the LED for the termination under test does not light,
the termination is miswired.
If the corresponding Tip LED lights, the subscriber
termination is reversed.

The six power supply LEDs indicate that the RT line unit
is installed in the RT enclosure and is supplying power
supply voltages to the channel unit.
If any one of the LEDs do not light, the RT line unit is
defective.
LED Test
switch When pressed, lights all the LEDs on the Streaker card.
If all LEDs do not light, the 9V battery is bad or the
FSU-796 List 5 is defective.

1Press the LED Test switch on the FSU-796 List 5 front panel and verify that all Tip and Ring LEDs
(T1-T8 and R1-R8) and power supply LEDs (-170 Vdc, 200 Vac, -30 Vdc, -52 Vdc, and ±5 Vdc)
are on.
• If no LEDs light, replace the 9V battery.
• If no LEDs light after replacing the 9V battery, replace the FSU-796 List 5 Streaker card.
• If any one of the LEDs do not light, replace the FSU-796 List 5 Streaker card.
1Slide the FSU-796 List 5 into the RT enclosure channel unit slot to be tested until the retaining latch on the
front panel locks into position. (Refer to Figure 1 for the channel unit locations.)
2Proceed to "Verifying the Channel Unit Slot Wiring."
Use the following procedure to verify the wiring from each channel unit slot in an FRE-765 RT enclosure to the
termination point.
1At the cable termination point, connect a jumper lead from frame ground to the appropriate Tip or Ring
subscriber termination and verify that the corresponding Tip or Ring LED on the FSU-796 List 5 is on.
• If the correct Tip or Ring LED lights, proceed to the next subscriber termination.
• If the Tip or Ring LED under test does not light, or the wrong LED lights, check the wiring to the RT
enclosure.
2Repeat the previous step for each channel card Tip and Ring subscriber termination.
3Proceed to "Testing the Line Unit Power Supply Voltages."
Verify that a 9V battery is installed on the FSU-796 List 5 Streaker card before starting this
procedure.
An RT line unit is not required when testing the channel unit slot wiring.
Refer to the appropriate FRE-765 RT enclosure technical practice for channel unit
subscriber terminations, and wire color or connector pin locations for the specific
FRE-765 RT enclosure to be tested.

Verifying the Channel Unit Slot Wiring
Use the following procedure to verify that the line unit power supply voltages are present at each of the channel
unit slots.
1Slide the FSU-796 List 5 into the RT enclosure channel unit slot to be tested until the retaining latch on the
front panel locks into position. (Refer to Figure 1 for the channel unit locations.)
2Verify that the -170 Vdc, 200 Vac, -30 Vdc, -52 Vdc, and ±5 Vdc LEDs are on.
• If any of the power supply LEDs do not light, replace the line unit.
• If none of the power supply LEDs light, check that power is applied.
3Repeat steps 1 and 2 for each channel unit slot.

An RT line unit must be installed and operating (with power applied) to supply the FSU-796
List 5 with the power supply voltages (-170 Vdc, 200 Vac, -30 Vdc, -52 Vdc, and ±5 Vdc)
required for this test.
