Abstract
A communication system including a switching system and a main distributor connected thereto via internal central office lines for the connection of the subscriber network lines is provided. The wiring backplane of the switching system is lengthened at one side to eliminate the internal connecting cables between the switching system and the internal side of the main distributor. The plug connectors of the internal side of the main distributor have exchange-side terminals directly pressed into the wiring backplane on the lengthened wiring backplane.

"COMMUNICATION SYSTEM HAVING A LENGTHENED BACKPLANE"
BACKGROUNT~ OF T~F. T~VFNTION
FIPI~1 of thr ~nv~nt;nn S The present invention is directed to a communication system coll,posed of a switching system and a main disL-il.u~or c~nn~t~ thereto via internal central office lines for the connection of the subscriber network lines.
n~r~pti-n of ~he ~2~1qtrd Art Communir~tinn systems have been separately constructed of a switching system and a main distributor. Respectively separate, spatially separated housing designs are implemented as floor and/or wall versions. The electrical connection to one another is made with a plurality of shielded and costly HVT patch cables that must be laid in specific cable channels. The space requilelne.lt and the assembly outlay on the floor or at the wall is 5~bs~nti~1, as is the specific length definition of the patch cables coupled thereto (fabrication, mounting/service logistics, expenses, p~r~gjng, etc.).
Switching systems are currently accommodated in housing or cabinet structures. At the back side of the wiring backplane or, respectively1 at the front side of the assemblies, the cll~riher lines are cclndurted via cable plugs and cables to an externally arranged main distributor (HVT) in a separate housing structure. For electrical reasons (EMF), shielded patch cables are usually used. The shield of the patch cables must be manually stripped upon exit from or entry into the housing to be shielded. Then the patch cable must be electrically connected to the housing. At the internal side of the main distributor, subscriber lines are placed onto the terminal posts of distribution strips and are electrically contacted. In the cable plug and at the distributor strips, the cable cladding must be stripped, the lead bundles uncovered and the individual leads must be stripped and c~mnPrted. The manuf~rtnring and assembly processes are especially time-concnming and costly.

2~ 6~021 SUlVrl\~RY OF T~F ~vFl~TIoN
It is an object of the present invention to provide a communication system of the species initially cited that can be more simply and i~-PAl~J-~ ely manufactured and assembled with respect to the expenditures for the cabling of the assemblies.
5This object is achieved in a communication system of the species initially cited having a wiring backplane of the switching system lengthened at one side. The plug connectors of the internal side of the main distributor have exchange-side terminals directly pressed into the wiring bac~lane on the lengthened wiring backplane.
In the inventive communication system, the switching system and the main distributor form 10a unit. The switching system is a component of the internal side of the distributor from a structura] point of view In the communication system of the present invention, the internal patch cables between the switching system and the internal side of the main distributor can be Plimin~t~l .
In an embodiment of the present invention, one piece of the wiring backplane is 15downwardly lengthened and the plug connectors of the internal side of the main distributor have their terminal posts directly pressed into the wiring backplane in an easily accessible way in this lengthened region. This embodiment provides an especially simple and cost-effective structure of the communication system.
Another embodiment of the inventive communication system provides that the lengthened 20part of the wiring backplane is separately attached and directly connected to the actual wiring backplane using press-in blades. A prior, separate construction of the switching system and the internal side of the main distributor is possible in this embodiment.
In order to be able to undertake a subseyuent modification of the lengthening of the wiring backplane, another embodiment of the inventive communication system provides the wiring 25b~fLl.l~ e as two wiring sub-backplanes conne~;~d to one another via a plug-type connector. This elllbodill,~nt provides flexibility that can be further increased since different plug-connec~of types can be used.

A e~el-lpl~y embodiment of a communi~tion system of the present invention is described below with reference to the drawings.
RRIFF DF~CRTPTION OF Tl~F nRAWTl~GS
FIG 1 is a longitudinal section through an exemplary ernbodiment of a conllllullication 5 system according to the present invention.
FIG 2 is a plan view onto the individual assemblies and colllponcnls of the communication system of the present invention shown in FIG 1.
FIGs 3-6 are various embodiments provided in the present invention for connecting an extension of the wiring backplane to the actual system wiring backplane.
DFTATT Fn DF.SCPcTPTION OF T~F PRFFFRRF.n FMT~ODTMF~TS
The inventive communication system is essentially composed of three units, namely an actual switching system 1, an internal side 2 of the main distributor and an external side 3 of the main distributor. The three units are arranged spatially separated from one another. In the communication system of the present invention, the switching system 1 and the internal side 2 of 15 the main distributor are connected to one another via a wiring b~krl~ne 5.
The wiring b~ ne serves the purpose of wiring the modules of the switching system 1 to one another as well as connecting the switching system 1 to the exchange-side terminals of the internal side 2 of the main distributor. This wiring backplane and its extension can be one piece. However, it is also possible to separately attach the lengthened part of the wlring backplane 20 to the actual system wiring backplane. As shown in FIG 3, this can occur directly with press-in blades in a multiboard technique or, as shown in FIG 4, with a direct plug or, as indicated in FIG
5, via a plug-type connector. FIG 6 shows that the connection of the actual system wiring backplane to the extension can occur via different types of plugs, i.e plugs from different m~nllf~rhlrers.
In the inventive communication system, the switching system 1 is inleE~I~led into the internal side 2 of the main distributor or is a conlponcnt of the internal side 2 of the main distributor from a structural point of view. Internal patch cables between the switching system 1 and the main distributor can thus be elimin~ed.
The external side 3 of the main dis~libutol is arranged under the internal side 2 of the main distributor, separated by a carrier 12 (see FIG 2) for special inserts. FIG I shows cable entry 11 S of the line network under the external side 3 of the main distributor, wherein the individual cables are conducted onto webs 14 for the line network. The shield contacting also occurs at the webs 14. The strapping between the internal side 2 of the main distributor and the external side 3 of the main distributor occurs with strapping cables that are guided by a right-hand strapping channel 13 and by non-threading strapping hooks 15 (see FIG 2). As shown in FIG 1, the entire 10 co~ ulucation system is secured to a frame 16 that is in turn secured to a wall with wall fasteners 17.
The actual switching system can be encapsulated by a perforated plastic or sheet metal cladding 4 having a potentially required shielding function, as well as for reasons of elimin~ting the ~ ip~ electrical power. Continuous grip shells 8 are provided for optimizing the assembly 15 and service conditions. In addition, the entire communication system can be plo~e~ed against unauthorized interventions by a lock 7.
It should be understood that various changes and modifications to the presently plefelled embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention 20 and without diminishing its attendant advantages. It is, therefore, intended that such changes and modifications be covered by the appended claims.
