OVERVIEW

This practice describes the PairGainHiGainTest Card HTC-439 List 1.

The HTC-439 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.

FEATURES

•Four-position slider switch (S1) that allows you to select the kind of test

you wish to perform 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.

•Miniature210jacks locatedwithinthe J1block thatprovide accesstoCO

and field Tip and Ring circuit sides.

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

which the HTC-439 is inserted to permit easy access to its test points.

TEST CARD

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

test as well as to frame ground. 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 all the way into the slot until the card is firmly seated.

TESTING ACIRCUIT

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

1Set the slider switch S1 to the type of 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.

All wiringexternal to the productshould followthe provisions
