A method of managing a DSL connection by a DSL server modem, including receiving signals from a DSL client modem at a first rate, determining, by the DSL server modem, a data content of the received signals, and initiating, by the DSL server modem, negotiation of a change in the rate of the DSL connection, responsive to the determination of the data content, so as to receive signals at a second rate different from the first rate.

The invention claimed is: 1. A DSL modem pool, comprising: an array of one or more processors which have a total processing power sufficient to handle connections with a predetermined number of client DSL modems at maximal data rates promised to the client modems; an analog front end adapted to connect the array of processors to a number of client DSL modems larger than the predetermined number of client DSL modems; and a scheduler adapted to dynamically determine at least one of the client modems to be handled at a rate substantially lower than the respective maximal data rate promised to the at least one client modem, so that the processing power required by the client modems connected to the array of processors does not exceed the total processing power of the array. 2. A modem pool according to claim 1, wherein the analog front end is adapted to connect to at least twice the predetermined number of client DSL modems. 3. A modem pool according to claim 1, wherein the array of one or more processors is adapted to communicate with more than half the client modems connected to the analog front end, at a rate substantially lower than the respective maximal data rate promised to the client modems. 4. A modem pool according to claim 1, wherein the array of one or more processors is adapted to communicate with the at least one of the client modems, at a rate lower than 20% of the respective maximal data rate of the client modem. 5. A modem pool according to claim 1, wherein the array of one or more processors is adapted to communicate with the at least one of the client modems, at a rate lower than 0.1 Mbps. 6. A modem pool according to claim 1, wherein the analog front end substantially continuously transmits signals to each of the client modems connected to the array of processors. 7. A modem pool according to claim 1, wherein the at least one of the client modems to be handled at a rate substantially lower than the respective maximal data rate is selected responsive to the amount of information transmitted to the client modems. 8. A modem pool according to claim 1, wherein the at least one of the client modems to be handled at a rate substantially lower than the respective maximal data rate is selected responsive to quality of service values assigned to the client modem. 9. A modem pool according to claim 1, wherein the scheduler is adapted to change the transmission rate of a first connection responsive to a need to change the transmission rate of a second connection. 10. A modem pool according to claim 9, wherein the scheduler is adapted to select the first connection as a connection with a low quality of service. 11. A modem pool according to claim 9, wherein the scheduler is adapted to select the first connection as a connection on which information was not transmitted for a longest time. 12. A modem pool according to claim 1, wherein the scheduler is adapted to handle a transmission such that substantially always the signals transmitted to at least one dynamically chosen client modem are at a rate substantially lower than a maximal allowed rate. 13. A modem pool according to claim 1, wherein the scheduler is adapted to initiate changing the data rate at which the signals are transmitted to at least one client modem, responsive to a determination that the transmitted signals do not include information. 14. A modem pool according to claim 1, wherein the scheduler is adapted to transfer the handling of a client modem from a first processor to a second processor if the client modem requires an increase in the processing power, which increase is above the available processing power of the first processor. 15. A modem pool according to claim 1, comprising a common memory which includes a record for each of the DSL client modems serviced by the modem pool and which is accessible by all the processors of the modem pool. 16. A modem pool according to claim 1, wherein each of the DSL client modems handled by the modem pool has a maximal data rate at which it may operate and wherein the combined processing power of all the processors of the modem pool is substantially less than the processing power required to handle all the DSL client modems handled by the modem pool at their respective maximal data rates. 17. A modem pool according to claim 16, wherein the combined processing power of all the processors of the modem pool is less than a fifth of the processing power required to handle all the DSL client modems handled by the modem pool at their respective maximal data rates. 18. A modem pool according to claim 1, comprising at least one switch which dynamically connects each of the interfaces of the front end to one or more of the plurality of processors, under instructions of the scheduler. 19. A modem pool according to claim 1, comprising at least one multiplexer which connects the interfaces of the front end to an at least one switch.
