Systems and methods for multi-pair ATM over DSL
View Patent ↗At a transmitter, an ATM cell stream is received from the ATM layer and is distributed on a cell-by-cell bases across multiple DSL PHY's. At the receiver, the cells from each DSL PHY are re-combined in the appropriate order to recreate the original ATM cell stream, which is then passed to the ATM layer.
1. An apparatus comprising:
a first transceiver operable at a first data rate; and
a second transceiver operable at a second data rate that is different than the first data rate,
wherein the transceivers are operable as bonded transceivers, and
one or more of the first and the second transceivers are operable to one or more of determine and utilize at least one parameter associated with operation of at least one of the first and second transceivers to reduce a difference in latency between the first and second transceivers.
2. The apparatus of claim 1 , wherein the at least one parameter is a Reed Solomon Coding parameter, an interleaving parameter or a framing parameter.
3. The apparatus of claim 1 , wherein the apparatus is customer premises equipment that is capable of transporting cells or ATM cells.
4. The apparatus of claim 1 , wherein the apparatus is customer premises equipment that is capable of transporting packets, Ethernet packets or Internet Protocol packets.
5. The apparatus of claim 1 , wherein the transceivers include at least one digital signal processor.
6. The apparatus of claim 1 , wherein the transceivers include at least one ASIC.
7. The apparatus of claim 1 , further comprising:
operating a third transceiver in a customer premises at the first data rate; and
operating a fourth transceiver in the customer premises at the second data rate,
wherein at least one second parameter associated with operation of at least one of the third and fourth transceivers is configured to reduce a difference in latency between the third and fourth transceivers.
8. An apparatus comprising:
three or more transceivers, wherein:
a first one of the transceivers is operable at a first data rate,
a second one of transceivers is operable at a second data rate that is different than the first data rate,
the first one of the transceivers and the second one of the transceivers are operable as bonded transceivers, and
one or more of the first and the second transceivers are operable to one or more of determine and utilize at least one parameter associated with operation of at least one of the transceivers and the second one of transceivers to reduce a difference in latency between the first one of the transceivers and the second one of the transceivers.
9. The apparatus of claim 8 , wherein the at least one parameter is a Reed Solomon Coding parameter, an interleaving parameter or a framing parameter.
10. The apparatus of claim 8 , wherein the apparatus is one or more linecards that are capable of transporting cells or ATM cells.
11. The apparatus of claim 8 , wherein the apparatus is one or more linecards that are capable of transporting packets, Ethernet packets or IP packets.
12. The apparatus of claim 8 , wherein each of the first one of the transceivers and the second one of the transceivers includes at least one digital signal processor.
13. The apparatus of claim 8 , wherein each of the first one of the transceivers and the second one of the transceivers includes at least one ASIC.
14. A method of operating devices of a telecommunications network, the method comprising:
configuring a first transceiver and a second transceiver to operate as bonded transceivers;
operating the first transceiver at a first data rate; and
operating the second transceiver at a second data rate that is different than the first data rate, wherein one or more of the first and the second transceivers are operable to one or more of determine and utilize at least one first parameter associated with operation of at least one of the first and second transceivers to reduce a difference in latency between the first and second transceivers.
15. The method of claim 14 , wherein the telecommunications network is a DSL network.
16. The method of claim 14 , wherein the at least one parameter is a Reed Solomon Coding parameter, an interleaving parameter or a framing parameter.
17. The method of claim 14 , wherein the first and second transceivers are transporting cells or ATM cells.
18. The method of claim 14 , wherein the first and second transceivers are transporting packets, Ethernet packets or Internet Protocol packets.
19. The method of claim 14 , wherein the at least one second parameter is a Reed Solomon Coding parameter, an interleaving parameter or a framing parameter.
20. The method of claim 14 , wherein the first, second, third and fourth transceivers transport cells or ATM cells.
21. The method of claim 14 , wherein the first, second, third and fourth transceivers transport packets, Ethernet packets or IP packets.
22. The method of claim 14 , further comprising transporting the packets, Ethernet packets or IP packets from a service provider to a DSL subscriber over a plurality of twisted pair wires.
