Abstract
A method of discontinuous transmission data communication in a digital subscriber line (DSL) transceiver unit, the method comprising determining that a number of a plurality of bits available to transmit is enough to fill a data transfer unit (DTU), forming a DTU, by a DTU framer, comprising the plurality of bits, transferring the DTU to a retransmission queue, and determining the DTUs from the retransmission queue to be transmitted over a next time period used for transmitting over the DSL subscriber line by the DSL transceiver unit.
Claims20
A method of discontinuous transmission data communication in a digital subscriber line (DSL) transceiver unit, the method comprising:
- determining that a number of a plurality of bits available to transmit is enough to fill a data transfer unit (DTU);
- forming the DTU, by a DTU framer, comprising the plurality of bits;
- transferring the DTU to a retransmission queue, wherein the retransmission queue is directly connected to the DTU framer;
- and
- determining DTUs from the retransmission queue to be transmitted over a next time period used for transmitting over a DSL by the DSL transceiver unit.
A discontinuous transmission data communication digital subscriber line (DSL) transceiver unit comprising:
- a retransmission queue;
- at least one processor configured to determine that a number of a plurality of bits available to transmit is enough to fill a data transfer unit (DTU);
- a DTU framer coupled to the at least one processor and directly connected to the retransmission queue, wherein the DTU framer is configured to:
- form the DTU comprising the plurality of bits;
- and
- transfer the DTU to the retransmission queue,
- wherein the at least one processor is further configured to determine DTUs from the retransmission queue to be transmitted over a next time period used for transmitting over a DSL by the DSL transceiver unit.
A method of discontinuous transmission data communication in a digital subscriber line (DSL) transceiver unit, the method comprising:
- accumulating bits until there are a plurality of bits sufficient to fill a data transfer unit (DTU);
- forming, by a DTU framer, the DTU comprising the plurality of bits;
- storing the DTU in a retransmission queue, wherein the retransmission queue is directly connected to the DTU framer;
- repeating the accumulating, the forming, and the storing steps while there is sufficient space in the retransmission queue;
- determining a number of DTUs to be transmitted from the retransmission queue over a next transmission time opportunity;
- transmitting the DTUs;
- and
- discarding the DTUs in the retransmission queue that are acknowledged by a receiver or overstayed in the retransmission queue over a time limit.
