2. Related Art
AT&T's u-Verse and Verizon's FiOS installations require significant work by installation crews to reconfigure the home wiring in order to provide service. One installation crew will need to connect a drop to the customer residence, and install an optical network terminal (ONT) for fiber-based services or install filters in a network interface device (NID) for very high bit rate digital subscriber line (VDSL)-based services. A second installation crew will then need to work inside the customer residence establishing a high data rate pathway to the modem/gateway and reconfigure existing home cabling to provision service from the modem/gateway to the point-of-use. Although this methodology ultimately provide high quality service to the customer, it is labor-intensive and expensive for the service provider.
Additionally, this technical approach is service provider dependent. If a customer makes the decision to switch service, the home cabling will need to be configured from a new home network topology. This “rewiring” is even more time consuming and even more expensive for the service provider.
Therefore, there is a need for an universal modular modem gateway that may meet some of the following objectives: 1. Provide a common base platform for installer; 2. provide a common form factor for the access module (primary service provider/customer premise interface/media conversion); 3. provide a common form factor for the modem module; 4. provide a centralized point from which to distribute signals into the customer residence; 5. provide a clear/simple methodology for technology/platform upgrades; and 6. provide power for the modem and router/gateway from a centralized point.
Exemplary implementations of the present invention address at least the above problems and/or disadvantages and other disadvantages not described above. Also, the present invention is not required to overcome the disadvantages described above, and an exemplary implementation of the present invention may not overcome any of the problems listed above.
A first embodiment of the invention is a universal network interface device including: an enclosure; an access module in the enclosure; a modem module attached to the enclosure and electrically connected to the access module; a switching power supply in the enclosure providing power to the modem module; and a battery in the enclosure providing power to the modem module.
The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, apparatuses and/or systems described herein. Various changes, modifications, and equivalents of the systems, apparatuses and/or methods described herein will suggest themselves to those of ordinary skill in the art. Descriptions of well-known functions and structures are omitted to enhance clarity and conciseness.
Hereinafter, the exemplary embodiments will be described with reference to accompanying drawings. If the components are the same in different drawings, the same item numbers are used to the extent possible for ease of reference.
This invention is related to U.S. Provisional Patent Application Nos. 61/407,578, filed on Oct. 28, 2010, 61/506,783 filed Jul. 12, 2011 and 61/542,578 filed Oct. 3, 2011 and PCT Application No. PCT/US2011/058310 filed Oct. 28, 2011. The modem module in this application and U.S. Provisional Patent Application No. 61/407,578 are the same and the access PCB board is similar in function to the access module in U.S. Provisional Patent Application No. 61/407,578.
The inputs/outputs include: a power in connection 10, such as a 110 V AC 1-phase power connection; a power output 5, such as a 12 V DC 0.8 A (10 W) nominal power jack (for a router/gateway (not shown)); a telco input 8, such as a CAT 3 or CAT 5 cable bi-directionally carrying VDSL and POTS signals; a premise output 6, such as a CAT 3 cable directionally carrying POTS signals; a residential security services jack 7, such as a CAT 3 or CAT 5 connection for residential security; a router/gateway input/output 4, such as a CAT 5 cable connection bi-directionally carrying Ethernet signals (to/from a router/gateway).
The dimensions of this embodiment of the universal NID 1 are approximately 9 inches by 9 inches by 2.5 inches.
A 20 W 110 V AC to 12 V DC switching power supply 13, with an input of a 110 V AC 1-phase power supply and an output of 12 V DC. This node is connected to the battery pack 16 and two 12 V DC power cords. One 12 V DC power cord is connected to the modem module 2. The second 12 V DC power cord is connected to the 12 V DC power jack 5 which will power the router/gateway.
The access PCB 15, may include different configurations, such as a 1 line VDSL module and a 2 line VDSL module. The function of the access PCT 15 is to de-multiplex/multiplex POTS and VDSL signals. The input 8 is a CAT 3 cable from the telco connected to the telco input. The output 6 is a CAT 3 cable to premise for phone service. Regarding interconnect, the modem module PCB 18 is connected to the access module PCB 15 with a CAT 5 interconnect cable 11. Also, a residential security services jack and switch 7 are provided to connect to home security services.
A power management PCB 19 connects the output of 20 W 110 V AC to a 12 V DC switching power supply 13 and output of battery 16 to two 12 V DC cords.
A battery pack 16 provides back-up 5000 M-Ah stored power to the modem module and any other externally connected devices in event of power loss. It may be a Li-Ion or Ni-Cad typical cell type, among other types.
A LAN interface PCB 17, the function of which is to provide means to the distribute Ethernet output of the modem within the residence using a HPNA roG.Hn protocol. In this embodiment, a G.Hn configuration is shown.
Some benefits and advantages of the invention include, but are not limited to:
1. Common platform.
2. Modular construction—uses same modem PCB and access module PCB base PCB as a typical outdoor unit.
3. Uses off the shelf power supply.
4. The battery pack is integral to the NID, as opposed to being a separate unit.
5. Common platform—common field practice for installation.
6. The modem module can be removed and replaced by customer—no truck rolls.
7. The battery pack can be removed and replaced by customer—no truck rolls.
8. The architecture separates the modem and router/gateway. Thus, the modem stays permanently installed in residence and allows telco service providers to push updates easily to the system and measure QoS data.
Although a few exemplary embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
