This modular adapter allows in-line testing for any plug/jack combination. It includes two 4-pair outlets plus a 150mm (6 in.) modular cord terminated with our patented 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 directly onto the MODAPT body. When used with Siemon's TESTAR® adapter and S110® test adapters, the MODAPT can be used to test connections on S66M and S110 blocks.
