HTC-439 List 2 November 12, 1999 1

OVERVIEW

The ADCHiGainTest Card HTC-439 List 2 provides a convenient

method of testing Central Office (CO) and Field Tip and Ring transmit and

receive pairs from any standard T1-239 repeater slot.

The width of theHTC-439 List 2 has been reduced from the List1 unit so that

the List 2 fits a four-slot HRE-504 enclosure without interfering with plugs

above or below it.

FEATURES

•Four-position slider switch (S1) that allows you to select tests on the

transmit (XMT) and receive (RCV) Tip and Ring pairs on CO and field

circuits:

–Open

–Short

–Loop Thru

–Loop Back (metallic)

•Test points that provide access to Tip and Ring circuits (CO and field)

and to frame ground.

•Miniature210 jacks located withinthe J1block that provideaccessto CO

and field Tip and Ring circuit sides.

•Designed to extend beyond the front plane of the shelf or enclosure into

which the HTC-439 List 2 is inserted to permit easy access to its test

points.

•Compatible with all ADC enclosures that support T1-239 mechanics.

TEST CARD

Test points on the HTC-439 (Figure 1) provide access to each active

card-edge connector pin including Frame Ground. These test points are

identified by the pin number to which they connect.

•The four-position test slider switch (S1) selects which test (Open, Short,

Loop Thru, or Loop Back) is to be performed on CO and field circuits.

•The Open switch position effectively provides a splitting-type access to

one pair of the CO and field sides and the 210 jacks.

•The Loop Back or Loop Thru switch positions allow you to use the two

miniature 210 jacks located within the J1 block.

All tests are run on both Side 1 and Side 2. Refer to “Testing a Circuit” on

page 3 for further information.

INSTALLATION

1Insert the HTC-439 into the shelf slot for the channel you want to test.

2Push the card into the slot until it is firmly seated.

TESTING ACIRCUIT

Use the HTC-439 to test circuits, as follows:

1Set the S1 slider switch to the test you want to perform (Open, Short,

Loop Thru, or Loop Back).

2Connect to test points as applicable. The connections of Tip and Ring

pairs of CO and field circuits for each setting of the switch are listed in

Table 1 on page 4 and illustrated in Figure 2 on page 5. (Pin numbers

correspond to the edge connector pins for each circuit.)

3Perform the selected test.

4Monitor the circuits at the corresponding test points on the card.

5Repeat steps 1 through 4 as required.

Allwiring externalto theproductshould follow the provisions

of the current edition of the National Electrical Code.
