Abstract

The present invention relates to a data distribution device comprising of a core electronics suite having at least two data ports where each port is in communication with its own network transport medium. At least two broadband transceivers, each in communication with its own broadband data port, enable sending and receiving of broadband data signals. At least two converters, each in communication with its own transceiver, enable the conversion of RF modulated data signals into data packets and the conversion of data packets into RF modulated data signals. The device includes a data switch, in communications with at least two converters and at least two broadband transceivers, for inspecting and routing data packets between data ports; a processor in communication with the data switch that controls the sending and receiving of data packets between at least two converters; and an exterior housing that is sealed and environmentally hardened to allow the data switch, the processor, and the converters with their transceivers, to operate in an outdoor environment.

Claims

1. An outdoor data distribution device, comprising:

a first exo-modular data module, including;

at least two data ports, each data port being externally accessible to allow manual connecting or disconnecting to one or more network transport mediums,

at least two transceivers for exchanging data with the two data ports,

at least two converters, each converter communicating with each transceiver respectively for converting the data to or from packet data,

a data switch, in communications with the at least two converters for inspecting and routing data packets between data ports,

a processor in communication with the data switch that controls the data switch,

an exterior housing that is sealed and environmentally hardened to protect at least one of the data switch, the processor, converters, and transceivers, from exposure to the outdoor environment.

2. The device of claim 1, further comprising a mid-plane connector for allowing modules to be inserted or removed from either side of a two-sided housing.

3. The device of claim 2, further comprising a first power module for extracting AC or DC power from an external power source, the power module supplying the other modules in the device through the mid-plane connector.

4. The device of claim 3, further comprising a power input connector in communication with independently power supplies of claim 3, allowing exo-modular power supplies to be inserted or removed from the device without disconnecting power supply cables.

5. The device of claim 1, further comprising a plurality of power modules, each for accepting power from a different external power source, the plurality of power modules substantially equally sharing the power consumption from the different external power sources.

6. The device of claim 1, further comprising at least two power modules, each module being connectable or removable while at least one other power module provides continuous power to the device.

7. The device of claim 1, further comprising means for allowing switch modules, transmission port modules, or power modules to be inserted or removed while input supply power is connected to the device.

8. The device of claim 1, further comprising a maintenance port with status indicators allowing installers to visually determine operational status of the device and any module in inserted in the device.

9. The device of claim 8, wherein the maintenance port is behind an environmentally sealed cover.

10. The device of claim 8, wherein the maintenance port is connected to a wireless transceiver that can transmit status of the device or any module and can receive maintenance commands to be interpreted by the processor.

11. The device of claim 1, further comprising at least one of a built-in or exo-modular Global Positioning System (GPS) that allows the device to be tracked, an exo-modular fiber optic transceiver port, and an exo-modular coaxial cable transceiver port.

12. The device of claim 1, further comprising at least one of an exo-modular ADSL, ADSL-2, VDSL, and VDSL-2 port.

13. The device of claim 1, further comprising at least one of an exo-modular wireless radio module with antenna connectors, an exo-modular Ethernet module, and an exo-modular Ethernet module supplying power-over-Ethernet (POE), an exo-modular layer 2 Ethernet switch module, an exo-modular layer 3 Ethernet switch module, and an exo-modular power supply module.

14. The device of claim 1, further comprising an exo-modular keying system for mechanically preventing modules from being inserted into improper module slots.

15. The device of claim 1, further comprising exo-modular modules that are physically connected to the device housing with positive-stop bolts that capture o-rings at a compression that seals each module to the housing, preventing environmental ingress or egress between the module and the housing.

16. The device of claim 1, further comprising exo-modular modules using a two-stage removal system, the first removal stage including a latch-stop requiring manual release of a latch to fully remove the module from the housing.

17. The device of claim 1, wherein the device communicates with a topology server through one or more of its transmission ports for auto-discovery and auto-configuration.

18. The device of claim 1, wherein the device communicates its status to a central management server, including information such as temperature, power levels, and data communications packet throughput and error rates.

19. The device of claim 1, wherein the device generates a removal alarm at a central monitoring server when the device or any of its exo-modular modules are removed.

20. The device of claim 1, wherein the device is placed in a maintenance state so that removal of the device or any of its exo-modular modules will not generate a removal alarm.

21. The device of claim 1, wherein the device uses an optional backplane connector system.

22. The device of claim 1, wherein the device is an exo-modular switch module that can support combinations of OSI layer 2, layer 3, and layer 4 protocols.

23. The device of claim 1, further comprising exo-modular option modules for optical transmission using gigabit interface connectors (GBIC), small form factor pluggable (SFP) connectors.

24. The device of claim 1, further comprising software that implements route redundancy to allow more than one medium, such as fiber or wireless, to provide connectivity to the exo-modular switch in the event that one of the bandwidth input sources experiences a failure such as a fiber cut.

25. The device of claim 1, further comprising an optional exo-modular TDM module supplying T1 services over copper wire.
