International Classification:

H04M 300

US Classification:

379328

Abstract:

A low frequency telecommunication digital network interface patch panel 10 is described having the capability of terminating and providing front access to one-hundred-sixty-eight low frequency network elements 12 and 14 that generate low frequency signals between 1 and 3 Mbps. The panel has a housing with twenty-one adjacent modules; each module being one inch in width and having an upper set of wire-wrap pins 38 and a lower set of wire-wrap pins 40 that are spaced at one-quarter inch on center from each other. The pins 38, 40 are arranged in upper columns and lower columns that are vertically aligned with each other. The pins 38, 40 extend forward from a printed circuit board 60 through front module members 62 to ends 54 and rearward through rear module member 64 to wire-wrap terminal ends 56. The ends 56 are adapted for permanent termination with twisted wire pairs of the network elements. The forward front ends 64 are adapted to receive a female access plug 120 having four wire-wrap pin cavities 126.

International Classification:

H05K 714

US Classification:

361796

Abstract:

A telecommunication network cross-connect panel 10 is described having a chassis 14 for receiving insertable modules 12, 212. The chassis 14 has a back wall 24 with a backplane printed circuit board 34. An array of rear coaxial connectors are mounted to the backplane printed circuit board 34 in columns of four connectors 36, 38, 40 and 42 for terminating and cross-connecting two pieces of telecommunication equipment per column. Female DIN connector receptacles 44 are mounted on the front side of the board 34 at spaced slot locations with each receptacle 44 electrically connected to a corresponding four backplane connectors of a corresponding column. A plurality of modules 12 are insertable into the slots for interconnecting male DIN connector plugs 58 into corresponding aligned DIN connector receptacles 44. A plug 58 is mounted on a rear end of a module printed circuit board 50. A plurality of coaxial mini-WECO jacks are mounted to a front end of the printed circuit board 50 and electrically connected through the board 50 to the plugs 58.

International Classification:

H04M 100

US Classification:

379327

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.
