Abstract

A system and method for coupling a communications device to a primary communications network having a first communications format and to a secondary communications network having a second communications format. The system and method can comprise a first port configured for connecting to the communications device, a second port configured for connecting to the primary communications network and facilitating the communication of the data between the primary communications network and the communications device through the first port.

Claims

1. A two port adapter configured as power sourcing equipment (PSE) for coupling an inline powered communications device to a communications network via the two ports of the adapter, the communications device configured for sending and receiving first data in a first communications format, the adapter comprising:

a first port of the two ports having a device connector having both inline power and first data connections for connecting to the communications device to facilitate the communication of the first data in the first communications format and the inline power between the adapter and the communications device, the inline power for use in operating the communications device;

a second port of the two ports having a network connector having both inline power and second data connections for connecting to a network cable for coupling to the communications network, the second port to facilitate communication of second data in a second communications format and the inline power between the network connector and the network cable, the second port coupled to the first port facilitating conduction of the inline power there-between, the network connector configured for connecting to a pair of conductors of the network cable for receiving both the inline power and the second data formatted in the second communications format, the first communications format different from the second communications format;

a translation module positioned between the first and second ports and connected thereto, the translation module configured for processing format transformation between the first data in the first communications format and the second data in the second communications format;

a power discovery module on board the adapter configured for implementing discovery logic by applying a power initialization process to the inline powered communications device upon connection to the first port by directly implementing a series of power checks in controlling the first port to determine whether the connected inline powered communications device is configured to receive the inline power; and

an onboard power regulator coupled to the inline power and configured for supplying operating power to the translation module and the power discovery module by stepping down incoming voltage of the inline power to one or more levels of the operating power;

Wherein said inline power and first data connections of the device connector are configured as two pairs of power pins for conducting the inline power and two pairs of data pins for conducting the first data.

2. The adapter of claim 1, wherein the device connector is configured as an RJ 45 connector.

3. The adapter of claim 1, wherein said inline power and second data connections are tip and ring connections coupled to the pair of conductors of the network cable.

4. The adapter of claim 1, wherein the network connector is configured as an RJ 21 connector.

5. The adapter of claim 1, wherein the second communications format is a dial-up communication protocol and the first communications format is a packet-based communication protocol.

6. The adapter of claim 1, wherein the second communications format is a two-wire communication protocol and the first communications format is an Ethernet communication protocol, such that both communication protocols are packet-based communication protocols.

7. The adapter of claim 4, wherein the second communications format is a two-wire communication protocol functioning as an Ethernet extender for transmitting the second data as Ethernet packets over the pair of conductors of the network cable.

8. The adapter of claim 3, wherein the network connector has extra connections unused for conducting the inline power and the second data.

9. A method for coupling an inline powered communications device to a communications network via a pair of ports of a power sourcing equipment (PSE) configured as a two port adapter, the communications device configured for sending and receiving first data in a first communications format, the method comprising:

communicating the first data to a first port of the two ports having a device connector having both inline power and first data connections for connecting to the communications device to facilitate the communication of the first data in the first communications format and the inline power between the adapter and the communications device, the inline power for use in operating the communications device;

translating the first data using a translation module positioned between the first port and a second port of the two ports, the translation module configured for processing format transformation between the first data in the first communications format and second data in a second communications format, such that the second port has a network connector having both inline power and second data connections for connecting to a network cable for coupling to the communications network, the second port facilitating communication of the second data in the second communications format and the inline power between the network connector and the network cable, the network connector configured for connecting to a pair of conductors of the network cable for receiving both the inline power and the second data formatted in the second communications format, the first communications format different from the second communications format, the second port coupled to the first port to facilitate conduction of the inline power there-between;

applying a power initialization process using a power discovery module on board the adapter to the inline powered communications device upon connection to the first port for implementing discovery logic by applying a series of power checks in controlling the first port to determine whether the connected inline powered communications device is configured to receive the inline power; and

supplying operating power to the translation module and the power discovery module through a onboard power regulator coupled to the inline power by stepping down incoming voltage of the inline power to one or more levels of the operating power;

Wherein said inline power and first data connections of the device connector are configured as two pairs of power pins for conducting the inline power and two pairs of data pins for conducting the first data.

11. The method of claim 9, wherein said inline power and second data connections are tip and ring connections coupled to the pair of conductors of the network cable.

12. The method of claim 9, wherein the network connector is configured as an RJ 21 connector.

13. The method of claim 9, wherein the second communications format is a dial-up communication protocol and the first communications format is a packet-based communication protocol.

14. The method of claim 9, wherein the second communications format is a two-wire communication protocol and the first communications format is an Ethernet communication protocol, such that both communication protocols are packet-based communication protocols.

15. The method of claim 12, wherein the second communications format is a two-wire communication protocol functioning as an Ethernet extender for transmitting the second data as Ethernet packets over the pair of conductors of the network cable.
