Description:
[0001]    This application claims the benefit of U.S. Provisional Application Serial No. 60/218,902, filed Jul. 18, 2000. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    The invention relates generally to the field of data communications and transmissions, and more particularly to the field of data communications involving computers, routers, controllers, modems, network devices, alarms and/or other related peripheral equipment, referred to as either Data Transmission Equipment (DTE) or Data Communications Equipment (DCE), where the invention relates most particularly to data communications accomplished via interconnection means comprising cables connected to the transmitting and receiving equipment by multi-pin adaptors, where the interconnection means allows for transmission of both data information streams and non-data signal streams, and where the data communications may involve either synchronous or asynchronous transmissions.  
           [0003]    This invention relates to data communications related to both EIA/TIA-232 and V.35 standards. Basic EIA/TIA-232 and V.35 Serial Communications incorporate the use of multi-pin connectors and multi-pair cable. Typical EIA/TIA-232 Serial Communications standards include 25 pin data connectors to include labeling each for an assigned function. There are multiple variations in configurations. Different forms of communication require different numbers and/or combinations of pins. Asynchronous mode could include anywhere from 3 to 9 pins or Synchronous to include 11. Typical V.35 Serial Communications standards include 34 pin data connectors to include labeling for each for an assigned function. There are multiple variations in configurations. Different forms of communication require different numbers and/or combinations of pins. Typical V.35 communications utilize 17 pins. Basic V.35 communications utilizes EIA/TIA-232 standards for the first ten required signals of Data Transmission.  
           [0004]    With the advances of technology increasing exponentially as time passes, better, faster and cheaper methods of communication are being required and developed. Typical RS-232 cable comprises a bundle of from 11 to 25 conductor wires, usually non-twisted and shielded. Because of interference or cross-talk problems within the cable itself, the usable lengths of this cable are limited to distances of less than 50 feet for high speed transmissions.  
           [0005]    This invention will allow the older EIA/TIA-232 standard to increase its reliable distance limitation while utilizing newer, cheaper transmission media such as Category-5 Unshielded Twisted Pair (UTP) cable, thus allowing EIA/TIA-232 to compete with newer transmission protocols or act as a reliable interim for inevitable transmission upgrades, while utilizing the same media as these new protocols. This invention will decrease overall cost to include connectors, cables and labor to approximately 50% of today&#39;s EIA/TIA-232 standards. Further benefits of both the EIA/TIA-232 and V.35 models allows users to utilize 4-pair data patch panels for quick installation and de-installation, while reducing the amount of space required for proper cable management.  
           [0006]    It is an object of this invention to provide interface adaptors for DTE and DCE which will enable Synchronous and Asynchronous data transmissions now requiring interfaces having greater than 8 active leads, pins or contacts for data and signal transmission to be transmitted over 4-pair Category-5 UTP cable, where the adaptors are constructed such that non-data stream leads are combined in a manner which allows proper delivery of all such non-data stream leads over 8 or less wires within the 4-pair Category-5 UTP cable, both in terms of signal content and sequence, such that data and signal communications are not compromised. It is an object to provide such adaptors having a standard female 8-pin or contact interface (RJ-45) for mating with a standard patch cord male 8-pin or contact interface and an opposing interface corresponding in configuration (male or female, as well as overall shape and size) and in the number of pins or contacts (e.g., 25, 26, 50, 60) to standard computer equipment interfaces and patch panels. It is an object to provide a system using such adaptors where positive voltage from the Data Terminal Equipment (DTE) signal (DTR) is used to provide the necessary positive voltage on leads required for the start-up sequence in RS232 signaling by selectively electrically connecting these leads together in the adapter. It is an object to provide a system where the 4-pair CAT-5 UTP cable carries RS232 Synchronous data signals, such that the primary leads for V.35 data signals are based on RS232 type signaling protocols (i.e., +3 V and −3 V).  
         SUMMARY OF THE INVENTION  
         [0007]    The present invention provides a means to transport Serial Data Communications across 4-Pair of Unshielded Twisted Pair Cable in accordance with EIA/TIA-232 or V.35 Serial Communications standards. The ten V.35 signals manipulated to run over 4-pair are transmitting signals in accordance with EIA/TIA-232 Standards. Any other signals not correlating to EIA/TIA-232 Standards are not utilized in this invention. The interface connector adaptors of the invention utilize eight pin RJ 45 metallic based contacts for use with RJ45 male end connectors, a prefabricated petroleum based enclosure, screw-type fasteners and insulated metallic-based or molded circuit board type conductors for connection between RJ45 conductors and Serial Connectors. Specific pin-outs for each connector adaptor are determined by the particular equipment interface of the computer communications equipment. Positive voltage from the DTE signal is used to provide the necessary positive voltage on leads required for the start up sequence in RS232 signaling by selectively electrically connecting these leads together in the adaptor.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0056]    With reference to the drawings, the invention will be described in detail with regard for the best mode and the preferred embodiments. In general, the invention comprises connector adaptors and a method of utilizing such adaptors to transport Serial Data Communications, either Synchronous or Asynchronous, across 4-Pair of Unshielded Twisted Pair Cable in accordance with EIA/TIA-232 or V.35 Serial Communications standards. The invention allows transmission of Serial Data Communications over a total of eight leads between Data Transmission Equipment (DTE) and Data Communications Equipment (DCE) where normally more than eight leads are utilized, wherein specific non-data leads are linked such that the proper non-data signals are still received in proper sequence.  
         [0057]    In RS232 signaling, the pins or leads of the DTE are assigned to carry specific signals. Pin  2  of the DTE is the Transmit Data (TD) pin carrying data to the DCE. Pin  3  is the Receive Data (RD) pin and accepts data from the DCE. Pin  4  is the Request To Send (RTS) pin. When voltage is present this signals that the receive buffer on the DTE is empty and is asking the DCE to send more data. Pin  5  is the Clear To Send (CTS) pin and when voltage is present indicates that the buffers in the DCE are empty and ready to receive more data. Pins  4  and  5  handle flow control. Pin  6  is the Data Set Ready (DSR) pin and when a voltage is present indicates that the DCE is ready. Pin  7  is ground, and is a reference point for the other signals. Pin  8  is the Carrier Detect (CD) pin, which indicates DCE ready. Pin  20  is the Data Terminal Ready (DTR) pin, which indicates DTE ready.  
         [0058]    In order to utilize the proper connector adaptor configuration, the equipment is examined to determine the necessary equipment interfaces for the DTE and DCE communication cable. For example, the standard interfaces are typically either a Cisco Systems 60 pin Molex type, an EIA/TIA-232 standard 25 pin type, a Smart Serial 26 pin, or a 50 pin type. Location and arrangement of pins, and whether male or female interfaces are required, are determined by the DTE and DCE equipment. The equipment interface of the connector adaptor is chosen to mate.  
         [0059]    The operative or active pins of the equipment interface on the adaptor are connected either directly to the pins of an RJ45 interface or are linked together in a manner such that a signal voltage directed to the linked pins is received by both, and this may be accomplished by standard known means such as hard-wiring or by use of a circuit board. Non-data signals are linked such that data transmission normally requiring more than 8 active pins, i.e. Synchronous data transmission, is accomplished through only 8 active pins. In this manner the number of necessary leads or lines within the communication cable is reduced to eight. To determine the proper pins to be linked, the core signals are isolated and the purpose of all signals is determined. The signal leads or pins carrying non-data streams are then linked in a manner which allows the non-data signals to be delivered and received in proper form and sequence by the DTE and DCE. Thus, in a data communications situation which normally requires greater than 8 pins, the adaptor provides the same communication with only 8 pins, the data being transmitted over a 4-pair (8 wire) unshielded twisted pair cable.  
         [0060]    The following embodiments show particular configurations as required by particular equipment interfaces and signaling protocols.
