150-439-102-02, Issue 2 Overview
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.
