Description: UNIVERSAL HTC-239 TYPE TEST CARD
11990 239 HTC Type T1 Repeater Housing Test Access Card Repeater CLEI 9937341
Comstock Telcom 239 Type T1 Test Access Card with LOOP THRU and LOOP BACK Feature. This access card is similar to the Pairgain HTC-239 and HTC-439 test card but instead the 11990 uses bantam jacks instead of test studs to access the copper pairs. Different from the Pairgain Test Access card the 11990 test access card has only loop through and loop back features.
The Comstock Telcom Universal Test Card installs into any slot of a standard T1 239 repeater enclosure and provides a method of testing both the Central Office (CO) and field-side circuits (transmit and receive pairs). The width of the Test Card allows it to fit into any T1 239 enclosure without interfering with plugs above or below it.LOOP THRU Mode:
side 1 IN (C.O.) Tip & Ring card edge pins 5-6 passes the T1 signal to side 1 OUT (Field) pins 3-4
side 2 IN (Field) Tip & Ring card edge pins 10-11 passes T1 signal to side 2 OUT (C.O.) pins 8-9
LOOP BACK Mode:
side 1 IN (C.O.) Tip & Ring card edge pins 5-6 passes signal back to side 2 OUT (C.O.) pins 8-9
side 1 OUT (Field) Tip & Ring card edge pins 3-4 passes signal back to side 2 IN (Field) pins 11-12
There are also two dual bantam jacks allowing you to insert and monitor test signals side 1 IN and OUT, side 2 IN and OUT.
