Abstract

A gateway for communicating telecommunication information between a telecommunication network and customer premises equipment includes a telecommunication interface and a packetization module. The telecommunication interface receives first telecommunication information for a first subscriber and second telecommunication information for a second subscriber. The packetization module generates first ATM cells for communicating the first telecommunication information using a first ATM adaptation layer associated with the first subscriber and generates second ATM cells for communicating the second telecommunication information using a second ATM adaptation layer associated with the second subscriber

Claims

1. A gateway for communicating telecommunication information between a telecommunication network and customer premises equipment, the gateway comprising:

a telecommunication interface operable to receive first telecommunication information for a first subscriber and second telecommunication information for a second subscriber; and

a packetization module operable to generate first ATM cells for communicating the first telecommunication information using a first ATM adaptation layer associated with the first subscriber and to generate second ATM cells for communicating the second telecommunication information using a second ATM adaptation layer associated with the second subscriber, wherein the first ATM adaptation layer is AAL2 and the second ATM adaptation layer is a hybrid AAL2/5.

2. The gateway of claim 1, further comprising a management module operable to associate the first subscriber with AAL2 in response to determining that a first broadband distribution platform between the gateway and the first subscriber'"'"'s customer premises equipment supports AAL2 and to associate the second subscriber with AAL2/5 in response to determining that a second broadband distribution platform between the gateway and the second subscriber'"'"'s customer premises equipment does not support AAL2.

3. The gateway of claim 1, further comprising a management module operable to associate the first subscriber with the first ATM adaptation layer in response to determining that a first broadband distribution platform between the gateway and the first subscriber'"'"'s customer premises equipment supports the first ATM adaptation layer.

4. The gateway of claim 1, further comprising a management module operable to associate the first subscriber with the first ATM adaptation layer according to a type, content, priority, or other criteria of the first telecommunication information.

5. A gateway for communicating telecommunication information between a telecommunication network and customer premises equipment, the gateway comprising:

a telecommunication interface operable to receive first telecommunication information for a first subscriber and second telecommunication information for a second subscriber; and

a packetization module operable to generate first ATM cells for communicating the first telecommunication information using a first ATM adaptation layer associated with the first subscriber and to generate second ATM cells for communicating the second telecommunication information using a second ATM adaptation layer associated with the second subscriber, wherein;

the first ATM adaptation layer is a hybrid AAL2/5; and

the packetization module generates the first ATM cells for communicating the first telecommunication information by generating AAL2 information encapsulating the first telecommunication information, generating the first ATM cells encapsulating the AAL2 information, and setting a field in each first ATM cell to indicate that each cell includes an end of a data unit.

6. The gateway of claim 5, wherein the packetization module sets a payload type field in each first ATM cell to “

1”

to indicate that each cell includes an end of a data unit.

7. A method of communicating telecommunication information between a telecommunication network and customer premises equipment, the method comprising:

receiving first telecommunication information for a first subscriber;

generating first ATM cells for communicating the first telecommunication information using a first ATM adaptation layer associated with the first subscriber;

receiving second telecommunication information for a second subscriber; and

generating second ATM cells for communicating the second telecommunication information using a second ATM adaptation layer associated with the second subscriber, wherein the first ATM adaptation layer is AAL2 and the second ATM adaptation layer is a hybrid AAL2/5.

8. The method of claim 7, further comprising:

associating the first subscriber with AAL2 in response to determining that a first broadband distribution platform between the gateway and the first subscriber'"'"'s customer premises equipment supports AAL2; and

associating the second subscriber with AAL2/5 in response to determining that a second broadband distribution platform between the gateway and the second subscriber'"'"'s customer premises equipment does not support AAL2.

9. The method of claim 7, further comprising:

determining that a first broadband distribution platform between the gateway and the first subscriber'"'"'s customer premises equipment supports the first ATM adaptation layer; and

associating the first subscriber with the first ATM adaptation layer in response to determining that the first broadband distribution platform support the first ATM adaptation layer.

10. The method of claim 7, further comprising associating the first subscriber with the first ATM adaptation layer according to a type, content, priority, or other criteria of the first telecommunication information.

11. A method of communicating telecommunication information between a telecommunication network and customer premises equipment, the method comprising:

receiving first telecommunication information for a first subscriber;

generating first ATM cells for communicating the first telecommunication information using a first ATM adaptation layer associated with the first subscriber;

receiving second telecommunication information for a second subscriber; and

generating second ATM cells for communicating the second telecommunication information using a second ATM adaptation layer associated with the second subscriber, wherein;

the first ATM adaptation layer is a hybrid AAL2/5; and

generating the first ATM cells for communicating the first telecommunication information further comprises;

generating AAL2 information encapsulating the first telecommunication information;

generating the first ATM cells encapsulating the AAL2 information; and

setting a field in each first ATM cell to indicate that each cell includes an end of a data unit.

12. The method of claim 11, wherein setting the field in each first ATM cell to indicate that each cell includes an end of a data unit further comprises setting a payload type field in each first ATM cell to “

1”

.

13. A gateway for communicating telecommunication information between a telecommunication network and customer premises equipment, the gateway operable to receive telecommunication information from the telecommunication network for communication to the customer premises equipment, the gateway further operable to generate AAL2 information encapsulating the telecommunication information, to generate ATM cells encapsulating the AAL2 information, to set a field in each ATM cell to indicate that each cell includes an end of a data unit, and to communicate the ATM cells to the customer premises equipment.

14. The gateway of claim 13, wherein the gateway sets a payload type field in each ATM cell to “

1”

to indicate that each cell includes an end of a data unit.

15. The gateway of claim 13, wherein the gateway is further operable to communicate the ATM cells to the customer premises equipment using DSL, cable, wireless, or other broadband distribution platforms.

16. A method of communicating telecommunication information between a telecommunication network and customer premises equipment, the method comprising:

receiving telecommunication information from the telecommunication network for communication to the customer premises equipment;

generating AAL2 information encapsulating the telecommunication information;

generating ATM cells encapsulating the AAL2 information;

setting a field in each ATM cell to indicate that each cell includes an end of a data unit; and

communicating the ATM to the customer premises equipment.

17. The method of claim 16, wherein setting the field in each ATM cell to indicate that each cell includes an end of a data unit further comprises setting a payload type field in each first ATM cell to “
