HTC-319 List 1 September 9, 1999 1
OVERVIEW
This practice describes the ADCHiGainTest Card HTC-319 List 1. The
HTC-319 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:
–Loop Back (metallic)
–Loop Thru
–Short
–Open
•Test points that provide access to Tip and Ring circuits (CO and field),
frame ground, and -48 Vdc power.
•Miniature210 jacks located withinthe J1block that provideaccess toCO
and field Tip and Ring circuit sides.
•Current-limiting resistorin series with -48 Vdctest point protects power
circuit from accidental shorting.
•Designed to extend beyond the front plane of the shelf or enclosure into
which the HTC-319 is inserted to permit easy access to its test points.

Overview 100-319-200-03, Issue 3

TEST CARD
Test points on the HTC-319 (Figure 1) provide access to each circuit under
test as well as to circuitground, frame ground, and -48 Vdc, if available. The
number of each test point corresponds to the edge connector pin of the circuit
under test. A 47 kΩresistor connected between the -48 Vdc source and the
test point limits current in case of accidental shorting.
The four-position testslider switch (S1) selects which test (Loop Back, Loop
Thru, Short, or Open) is to be performed on CO and field circuits. The Open
switch position effectively provides a splitting 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-319 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-319 to test circuits, as follows:
1Set the slider switch S1 to the type of test you want to perform (Loop
Back, Loop Thru, Short, or Open).
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 externaltotheproductshould follow the provisions
of the current edition of the National Electrical Code.
