In-line Modular Adapter allows in-line testing for any
plug/jack combination. It includes two 4-pair jacks plus a
modular cord terminated with 4-pair "universal" plug for
accessing any standard 6- or 8-position jack.
Individual conductors are broken out by pin number and
correspond to eight separate test pads. Test equipment can
be securely attached to the test pads using alligator clips.
For quick reference in the field, USOC, T568A, and T568B
wiring charts are printed right onto the body.
