FIELD DATA DISTRIBUTION SYSTEM WITH FIBER OPTIC CONVERTER
Background of the Invention
Background of the Invention
[0002] The present invention relates to field communication distribution equipment and, more particularly, to improvements in individual and grouped connectors for such equipment and for testing the integrity of circuits employing such connectors.
[0003] The J-1077 A/U distribution box (hereinafter referred to simply as the "J-1077") is used to interconnect military field telephones and other communication devices in mobile, transportable, and semi-permanent installations. The J-1077 has provisions for connection of one or two 26 conductor-pair cables to a set of 26 pairs of spring post connectors mounted on a panel within the box. As such, the J-1077 can interconnect two 26-pair cables or can terminate a single 26-pair cable and provide connections to the conductors within the cable, such as for telephone sets or test equipment. The J-1077 has been in use for several decades and has proved to be generally rugged and reliable in

varied field conditions. Additional information about the J-1077 distribution box can be obtained from Associated Industries of North Hollywood, CA (www.associated-ind.com) and from other sources.
[0004] Although generally successful, the J-1077 has some shortcomings. The configuration of the spring post connectors requires that wires be stripped before insertion into the posts. Stripping sometimes damages some of the strands of a conductor, causing them to break off, thereby reducing the signal carrying capability of the conductor. Stripping is also time- consuming if a large number of connections need to be made at one time.

Stripping sometimes damages some of the strands of a conductor, causing them to break off, thereby reducing the signal carrying capability of the conductor. Stripping is also time- consuming if a large number of connections need to be made at one time.
[0005] Another problem with the J-1077 is that if a communication malfunction occurs in a system using J-1077 distribution boxes and cables, it is often difficult and time-consuming to isolate the problem among the possible 26 circuits which may be in use. At present, the usual procedure is to disconnect and reconnect each wire until the problem is isolated. A related problem is detecting the location of a break or cut in the cable or unauthorized connections to the network, such as by an enemy. Finally, there are no provisions on a standard J-1077 box for connection of computers thereto to enable field networking of computers or data communication between computerized devices using the J-1077 system.
[0006] Some types of military communication equipment have optical data signal interfaces which utilize optical fiber communication media. Optical data signals have a number of advantages in military applications, including high efficiency over long distances, high data rates, difficulty of tapping by an enemy, and the like. There is also a need for converting signals carried by optical fiber media to electrical data signals for carriage by conventional copper based cables.

Summary of the Invention
[0007]
The present invention provides a number of improvements in J-1077 type distribution boxes. In the present invention, the spring post connectors are replaced by sets of insulation displacement connectors (IDC) mounted on a connector panel.
Each insulation displacement connector generally has a movable top section which comprises two wire insertion holes and a lower fixed section which houses a pair of terminal strips.
The terminal strips have a wire engaging portion at one end for engaging and making electrical contact with a wire. The terminal strips are generally parallel to one another but offset to provide a sufficient dielectric strength between them. In order to establish an electrical connection between the wires and the terminal strips a user first opens the top section, i.e., pivots the top section to its open position, inserts the pair of wires, and then closes the top section. Upon closing the top section of the connector, the wires are forced through the terminal strip engaging portion to make electrical and mechanical contact with the terminal strips. To remove the wires and/or break the electrical connection, the process is reversed. Each spring binding post on the connector panel of the J-1077 distribution box is replaced by an insulation displacement connector unit. The connectors of the present Invention are mounted on the J-1077 panel in pairs in the same manner as the spring binding posts they replace.

The connectors typically carry audio frequency communication signals. In order to facilitate troubleshooting to find which circuit may have a problem, it is a common practice to remove a conductor from a binding post, one at a time, until the problem circuit is identified. Such disconnecting and reconnecting is laborious and can damage the stripped wire ends, requiring that the wire end be stripped before reconnecting. The present invention overcomes this problem by providing a test switch in at least one conductor of each pair_ By this means, the test switch can be opened to disconnect the circuit instead of physically removing the conductor from the connector.
Preferably, a double pole, single throw switch is connected between the pairs of terminals of the pair of connector devices.

[0009] The present invention provides a means of detecting the approximate location of a cut or break in one of a series of interconnected cables of the type that are used with the J-1077 distribution box. Typically, the cables are formed by 26 numbered pairs of conductors. Normally, only 25 pairs carry communication signals, while the No.
26 pair is used for testing and troubleshooting purposes. The present invention provides at least one resistor per cable, connected across the No. 26 conductor pair. When a plurality of cables are interconnected end to end by J-1077 boxes, the resistors of the cables are connected in parallel. If the resistance of the parallel combination is measured, the number of unbroken cable sections can be determined from the composite resistance and compared with the composite resistance expected from the number of cables present.

Detailed Description of the Invention [00261 As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.
[00271 Referring to the drawing in more detail, the reference numeral 1 (Figs. 2 and 3) generally designates an improved field communication distribution box which embodies the present invention. The box 1 generally includes an access door or lid 2 hingedly connected thereto and a connector panel 3 positioned in the box 1 and having pairs 4 of insulation displacement connectors 5, test switches 6, and auxiliary connectors 7 mounted thereon. The box 1 has box connectors 8 mounted on sides thereof to enable connection of cables 9 to the connectors 5 and 7 thereof. Conversely, the connectors 5 and 7 enable connection of communication devices 10 to the cables 9 (Fig. 1) for communication with other devices 10 (Fig. 1) connected to the cables 9.
[00281 Referring to Fig. 1, the conventional field communication distribution box 14, with the military designation J-1077 NU or simply J-1077, has a plurality of spring post connectors 15 mounted on a panel 16. The box 14 has the capability of interconnecting a pair of the cables 9 and provides for the connection of communication devices 10, such as ..
telephone sets, to conductor pairs in the cables 9. Fig. 1 shows a cable reel 17 on which a cable 9 is stored and from which it is paid out from one box 14 to the next.
The illustrated cable 9 (designated as CX-4566 A/G) has 26 numbered pairs of conductors and terminates at each end in a multi-terminal cable connector 18 (designated as a U-185 BIG
connector).
The cable connectors 18 mate with one of the box connectors 8 (designated U-connectors) to interconnect two cables 9 and to enable connections of the devices 10 to the conductors of the cables 9.
[00291 The insulation displacement connector 5 generally has a movable top section 21 which comprises two wire insertion holes and pivotally connected to a lower fixed section 22 which houses a pair of terminal strips. The terminal strips (not shown) have a wire engaging portion at one end for engaging and making electrical contact with a wire.
The terminal strips are generally parallel to one another but offset to provide a sufficient dielectric strength between them. The top movable section 21 of the connector 5 pivots about a fixed axis located toward the back side of the connector. The top section 21 has a movable latch member to maintain the top section in its closed position. To open the top section, a user the top section to its raised or open position (Fig. 8). When the top section is open, the terminal strips do not intersect the wire insertion holes, and when the top section is closed (Fig. 7), the terminal strips intersect the wire insertion holes. In order to establish an electrical connection between the wires and the terminal strips a user first opens the top section, i.e., pivots the top section to its open position, inserts the pair of wires, and then closes the top section. Upon closing the top section of the connector, the wires are forced through the terminal strip engaging portion to make electrical and mechanical contact with the terminal strips. To remove the wires and/or break the electrical connection, the process is reversed. A preferred type of insulation displacement connector is manufactured by Channell Commercial Corporation of Temecula, CA
(www.channellcomm.com) and sold under the trademark Mini-Rocker. Such connectors are also sometimes referred to as Mil-Lok connectors.
[0030] Each set spring binding posts 15 on the connector panel of the conventional J-1077 distribution box 14 is replaced by a set 4 of insulation displacement connector units or connector devices 5. The pair of connector units 5 provides for redundancy should one of the receptacles malfunction or be damaged. The insulation displacement connectors 5 enable faster and more reliable connections since the wires to be inserted do not require stripping. The terminals 5' (Fig. 9) of each connector unit 5 are connected to associated pairs of conductors 8' in the box connectors 8. Referring to Fig. 9, the terminals of a first one of the pair 4 of connector units 5 are connected to the box connector 8 on one side of the box 1 while the terminals of the second of the pair 4 are connected to the box connector 8 on the opposite side of the box 1.
[0031] In order to facilitate troubleshooting to find which circuit may have a problem, it is a common practice with the older box 14 to remove a conductor from a binding post 15, one at a time, until the problem circuit is identified. Such disconnecting and reconnecting is laborious and can damage the stripped wire ends, requiring that the wire end be stripped before reconnecting. The present invention overcomes this problem by providing a test switch 6 to interconnect the sets of terminals of each pair 4 of connector units 5. A double pole, single throw switch configuration is preferred. When the switch contacts are closed, the terminals of each pair 4 are interconnected. However, when the switch contacts are opened, the conductors of cables 9 on both sides of the box 1 can be individually tested, without removing wires from the connector units 5.
[0032] The present invention provides a means of detecting the approximate location of a cut or break in one of a series of interconnected cables 9. Typically, the cables 9 are =
formed by 26 numbered pairs of conductors. Normally, only 25 pairs carry communication signals, while the No. 26 pair is used for testing and troubleshooting purposes.
[0033] Referring to Fig. 10, the present invention provides at least one resistor 28 per cable, connected across the No. 26 conductor pair. The value of the resistor is standardized and may range from about 1000 ohms (1 ki(ohm) to several hundred kilohms.
A number of cables 9 are normally strung together end-to-end using boxes 10 or other kinds of appropriate connectors. Normally, a technician will be aware of the exact number of cables 9 present in a given communication network. Each cable 9 added, in the present invention, connects an additional resistor 28 in parallel, thereby further dividing the equivalent resistance of all the interconnected resistors 28. Additionally, the resistance of a given length of the conductor pair is known. The unbroken length of the composite cable is related to the equivalent resistance measured across the No. 26 conductor pair. If the value of the standard resistor is relatively high, the in-line resistance of the conductor pair is less significant in proportion to the standard resistors, such that the equivalent resistance of the cable is effectively the parallel combination of the standard resistors.
Thus, the equivalent resistance of the cable is inversely proportional to the length of the composite cable.
[0034] For example, if the composite cable is formed by ten cable sections, each with a standard resistor connected across the No. 26 pair, then the equivalent resistance measured is one tenth of the value of the standard resistor. However, if ten cable sections should be present and the resistance measured by an ohm meter 30 from one end is, for example, one seventh the value of the standard resistor, then the technician knows that there is a break in the eighth section. By this means, the broken cable section can be replaced or repaired quickly and directly without the need to inspect each section.
Alternatively, resistor 28 may be connected across each end of the No. 26 pair of each =
cable section 9. By this means, the integrity of a single cable section 9 can be determined by measuring the resistance across the No. 26 conductor pair.
[00351 The present invention also contemplates connecting a cable monitor circuit to the No. 26 cable pair which monitors the equivalent resistance of the composite cable.
Such a cable monitor would preferably be based on a programmable digital computer or at least a programmable microprocessor to provide for a variety of desirable features. The number of sections and the value of the standard resistor are entered into the monitor circuit. If the monitored resistance varies by greater than a selected tolerance, an alarm is activated. The change in resistance could be a consequence of the cable being damaged or being disconnected by an enemy to insert listening equipment into the line.
In either case, once the occurrence to line interruption has been alerted, the approximate location of the break can be located by the procedures described previously.
[0036] In some applications, it may be desirable to provide in-line electrical fuses (not shown) to the conductors of the cable to protect circuits and equipment connected thereto. Such fuses may be rated at relatively low levels of current, such as milliamperes, because of the relatively low power levels of signals intended to be carried by the conductors of the system. The fuses protect the circuits connected thereto from damage due to short circuits, current surges, and the like. The fuses are preferably provided in such a manner that they can be easily replaced if blown.
[0037] In order to provide for digital communications between computers and computerized equipment, the improved type distribution box 1 of the present invention may have various types of auxiliary connectors 7 having auxiliary connector terminals 7' interconnected to the terminals 5' of the insulation displacement connector units 5. Such connectors can include, but are not limited to, RJ-45, RJ-11, and RJ-12 modular type connectors; BNC type connectors; F-type connectors, fiber optic adapters, and other *
connectors commonly employed for interconnections between computers, computer networks, modems, and the like. Conductors of the cables 9 interconnecting the boxes 1 and carrying data between computers may be shielded separately from the other conductor pairs to minimize possible interference to and from other signals on other conductor pairs.
Data connectors and associated cable conductors would provide some limited computer networking capabilities in addition to more conventional analog voice communications in systems employing conventional J-1077 type distribution boxes.

[00391 Fig. 11 diagrammatically illustrates an embodiment of the distribution box 44 incorporating media converter circuitry 45 for converting data formats between an electrical data format and an optical data format. The box 44 includes auxiliary connectors 47 and 48, of which connector 47 is an electrical data connector such as an RJ-45 Ethernet type connector and connector 48 is an optical connector such as an ST type optical connector.
In general, the media converter bilaterally or bidirectionally converts between an electrical data signal format carried by the electrical connector 47 and an optical data signal format carried by the optical connector 48. The media converter circuit 45 may, for example, be a Signamax Connectivity Systems 065-1195 unit from AESP, Inc.
(www.sionamax.com). It is foreseen that other types of media converter units could alternatively be employed. The illustrated media converter converts from a 1000Base-T format, a gigabit Ethernet format for a twisted pair of electrical conductors, to an 1000Base-SX format, a gigabit optical Ethernet format for carriage by an optical fiber. The illustrated media converter 45 is powered by a DC power source 50 which may be a transformer and rectifier unit plugged into a power strip or generator, a battery of the appropriate voltage, or the like. The media converter 45 allows optical equipment 52 with a fiber optic interface to communicate data with electrical equipment 54 having an electrical Ethernet interface and vice versa. The electrical equipment 54 can be local to the distribution box 44 or can be remote from the box 44 and connected by a cable similar to the cable 9 described above and connected to a local box connector 56, similar to the box connector 8. The DC power source 50 may be connected to a panel indicator, such as an LED 58 to indicate activation of the media converter 45. The power source 50 may also be connected to the box connector 56 to provide DC power through a cable connected to the box connector 56 remote from the distribution box 44.
[0040] It is to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.

Detailed Description of the Invention [00261 As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.
[00271 Referring to the drawing in more detail, the reference numeral 1 (Figs. 2 and 3) generally designates an improved field communication distribution box which embodies the present invention. The box 1 generally includes an access door or lid 2 hingedly connected thereto and a connector panel 3 positioned in the box 1 and having pairs 4 of insulation displacement connectors 5, test switches 6, and auxiliary connectors 7 mounted thereon. The box 1 has box connectors 8 mounted on sides thereof to enable connection of cables 9 to the connectors 5 and 7 thereof. Conversely, the connectors 5 and 7 enable connection of communication devices 10 to the cables 9 (Fig. 1) for communication with other devices 10 (Fig. 1) connected to the cables 9.
[00281 Referring to Fig. 1, the conventional field communication distribution box 14, with the military designation J-1077 NU or simply J-1077, has a plurality of spring post connectors 15 mounted on a panel 16. The box 14 has the capability of interconnecting a pair of the cables 9 and provides for the connection of communication devices 10, such as ..
telephone sets, to conductor pairs in the cables 9. Fig. 1 shows a cable reel 17 on which a cable 9 is stored and from which it is paid out from one box 14 to the next.
The illustrated cable 9 (designated as CX-4566 A/G) has 26 numbered pairs of conductors and terminates at each end in a multi-terminal cable connector 18 (designated as a U-185 BIG
connector).
The cable connectors 18 mate with one of the box connectors 8 (designated U-connectors) to interconnect two cables 9 and to enable connections of the devices 10 to the conductors of the cables 9.
[00291 The insulation displacement connector 5 generally has a movable top section 21 which comprises two wire insertion holes and pivotally connected to a lower fixed section 22 which houses a pair of terminal strips. The terminal strips (not shown) have a wire engaging portion at one end for engaging and making electrical contact with a wire.
The terminal strips are generally parallel to one another but offset to provide a sufficient dielectric strength between them. The top movable section 21 of the connector 5 pivots about a fixed axis located toward the back side of the connector. The top section 21 has a movable latch member to maintain the top section in its closed position. To open the top section, a user the top section to its raised or open position (Fig. 8). When the top section is open, the terminal strips do not intersect the wire insertion holes, and when the top section is closed (Fig. 7), the terminal strips intersect the wire insertion holes. In order to establish an electrical connection between the wires and the terminal strips a user first opens the top section, i.e., pivots the top section to its open position, inserts the pair of wires, and then closes the top section. Upon closing the top section of the connector, the wires are forced through the terminal strip engaging portion to make electrical and mechanical contact with the terminal strips. To remove the wires and/or break the electrical connection, the process is reversed. A preferred type of insulation displacement connector is manufactured by Channell Commercial Corporation of Temecula, CA
(www.channellcomm.com) and sold under the trademark Mini-Rocker. Such connectors are also sometimes referred to as Mil-Lok connectors.
[0030] Each set spring binding posts 15 on the connector panel of the conventional J-1077 distribution box 14 is replaced by a set 4 of insulation displacement connector units or connector devices 5. The pair of connector units 5 provides for redundancy should one of the receptacles malfunction or be damaged. The insulation displacement connectors 5 enable faster and more reliable connections since the wires to be inserted do not require stripping. The terminals 5' (Fig. 9) of each connector unit 5 are connected to associated pairs of conductors 8' in the box connectors 8. Referring to Fig. 9, the terminals of a first one of the pair 4 of connector units 5 are connected to the box connector 8 on one side of the box 1 while the terminals of the second of the pair 4 are connected to the box connector 8 on the opposite side of the box 1.
[0031] In order to facilitate troubleshooting to find which circuit may have a problem, it is a common practice with the older box 14 to remove a conductor from a binding post 15, one at a time, until the problem circuit is identified. Such disconnecting and reconnecting is laborious and can damage the stripped wire ends, requiring that the wire end be stripped before reconnecting. The present invention overcomes this problem by providing a test switch 6 to interconnect the sets of terminals of each pair 4 of connector units 5. A double pole, single throw switch configuration is preferred. When the switch contacts are closed, the terminals of each pair 4 are interconnected. However, when the switch contacts are opened, the conductors of cables 9 on both sides of the box 1 can be individually tested, without removing wires from the connector units 5.
[0032] The present invention provides a means of detecting the approximate location of a cut or break in one of a series of interconnected cables 9. Typically, the cables 9 are =
formed by 26 numbered pairs of conductors. Normally, only 25 pairs carry communication signals, while the No. 26 pair is used for testing and troubleshooting purposes.
[0033] Referring to Fig. 10, the present invention provides at least one resistor 28 per cable, connected across the No. 26 conductor pair. The value of the resistor is standardized and may range from about 1000 ohms (1 ki(ohm) to several hundred kilohms.
A number of cables 9 are normally strung together end-to-end using boxes 10 or other kinds of appropriate connectors. Normally, a technician will be aware of the exact number of cables 9 present in a given communication network. Each cable 9 added, in the present invention, connects an additional resistor 28 in parallel, thereby further dividing the equivalent resistance of all the interconnected resistors 28. Additionally, the resistance of a given length of the conductor pair is known. The unbroken length of the composite cable is related to the equivalent resistance measured across the No. 26 conductor pair. If the value of the standard resistor is relatively high, the in-line resistance of the conductor pair is less significant in proportion to the standard resistors, such that the equivalent resistance of the cable is effectively the parallel combination of the standard resistors.
Thus, the equivalent resistance of the cable is inversely proportional to the length of the composite cable.
[0034] For example, if the composite cable is formed by ten cable sections, each with a standard resistor connected across the No. 26 pair, then the equivalent resistance measured is one tenth of the value of the standard resistor. However, if ten cable sections should be present and the resistance measured by an ohm meter 30 from one end is, for example, one seventh the value of the standard resistor, then the technician knows that there is a break in the eighth section. By this means, the broken cable section can be replaced or repaired quickly and directly without the need to inspect each section.
Alternatively, resistor 28 may be connected across each end of the No. 26 pair of each =
cable section 9. By this means, the integrity of a single cable section 9 can be determined by measuring the resistance across the No. 26 conductor pair.
[00351 The present invention also contemplates connecting a cable monitor circuit to the No. 26 cable pair which monitors the equivalent resistance of the composite cable.
Such a cable monitor would preferably be based on a programmable digital computer or at least a programmable microprocessor to provide for a variety of desirable features. The number of sections and the value of the standard resistor are entered into the monitor circuit. If the monitored resistance varies by greater than a selected tolerance, an alarm is activated. The change in resistance could be a consequence of the cable being damaged or being disconnected by an enemy to insert listening equipment into the line.
In either case, once the occurrence to line interruption has been alerted, the approximate location of the break can be located by the procedures described previously.
[0036] In some applications, it may be desirable to provide in-line electrical fuses (not shown) to the conductors of the cable to protect circuits and equipment connected thereto. Such fuses may be rated at relatively low levels of current, such as milliamperes, because of the relatively low power levels of signals intended to be carried by the conductors of the system. The fuses protect the circuits connected thereto from damage due to short circuits, current surges, and the like. The fuses are preferably provided in such a manner that they can be easily replaced if blown.
[0037] In order to provide for digital communications between computers and computerized equipment, the improved type distribution box 1 of the present invention may have various types of auxiliary connectors 7 having auxiliary connector terminals 7' interconnected to the terminals 5' of the insulation displacement connector units 5. Such connectors can include, but are not limited to, RJ-45, RJ-11, and RJ-12 modular type connectors; BNC type connectors; F-type connectors, fiber optic adapters, and other *
connectors commonly employed for interconnections between computers, computer networks, modems, and the like. Conductors of the cables 9 interconnecting the boxes 1 and carrying data between computers may be shielded separately from the other conductor pairs to minimize possible interference to and from other signals on other conductor pairs.
Data connectors and associated cable conductors would provide some limited computer networking capabilities in addition to more conventional analog voice communications in systems employing conventional J-1077 type distribution boxes.
