Ibm Cabling System Modular Jack Adapter

A modular adapter which permits the concurrent use of phone, data and token-ring applications using an eight-wire cabling system is described. The adapter offers a convenient and flexible means of interconnecting these disparate devices into an integrated system.

Two alternative embodiments of the adapter are shown in Figs. 1a and 1b. Fig. 1a shows a unitary molded adapter where an eight-pin miniature-modular male jack is wired to three six-pin miniature-modular female jacks labelled A, B and C. Fig. 1b shows an alternative where the six-pin miniature-modular female jacks are in a separate plastic housing from the eight-pin miniature-modular male jack, and the two housings are connected by a ten-foot length of cable.

Fig. 2 shows the wiring diagram of the modular jack adapter. Female jack A has its third and fourth pins wired to the fourth and fifth pins, respectively, of the eight-pin jack. Female jack B has its second and fifth pins wired to the third and sixth pins, respectively, of the eight-pin jack. Female jack C has its second, third, fourth and fifth pins wired to the first, second, seventh and eighth pins, respectively, of the eight-pin jack.

Female jacks A and B can be used for either phone or data lines. Female jack C is intended for use with a token ring or similar computer system. Alternatively, a phone splitter could be placed in female jack C to obtain two data or phone lines.
