Abstract
A low frequency (1-3 Mbps) telecommunication network cross-connect panel 10 is described for cross-connecting eighty-four fiber multiplex circuit elements 12 and eighty-four digital loop carrier circuits 14. The panel 10 has a housing 16 for supporting twenty-one modules 30 in which each module 30 has an upper patch access section 34 and a lower cross-connection field section 36. The upper section 34 includes two sets of front access wire-wrap pins 50 and 56 for providing front patch access capability utilizing a female patch plug 130. The lower cross-connection section 36 includes two sets of cross-connect pins 62 and 68 providing eighty-four columns of eight pins each defining a cross-connect field. Each module 30 includes a printed circuit board 40 for physically electrically interconnecting the pins through electrical circuits 100, 102, 104, and 106 as illustrated in FIG. 5. The printed circuit board includes an electrical switch means 108 that is a make-before-break arrangement in which front access contact is made prior to interrupting the circuit 100, 102, 104 and 106.
