Abstract
A method for transmitting and receiving leased line data, an apparatus for transmitting leased line data, and an apparatus for receiving leased line data are provided. The method includes storing received leased line data in a FIFO; packing the leased line date stored in the FIFO into the payload of a DSL frame; and transmitting the packed DSL frame. According to the method, leased line data can be transparently transmitted by adding minimum function blocks to the DSL modem, and with the simple circuit structure, the blocks can be integrated into one chip such that no additional external circuits are needed and a low-priced DSL modem chip that can transmit leased line data can be implemented.
Claims18
A method for transmitting leased line data comprising:
- storing received leased line data in a FIFO;
- packing the leased line date stored in the FIFO into the payload of a DSL frame;
- and
- transmitting the packed DSL frame.
A method for receiving leased line data comprising:
- receiving a DSL frame in which leased line data is packed;
- unpacking the leased line data from the received DSL frame payload;
- and
- sending the unpacked leased line data to a FIFO.
An apparatus for transmitting leased line data comprising:
- a FIFO which stores received leased line data;
- and
- a packing unit which packs leased line data stored in the FIFO into the payload of a DSL frame.
An apparatus for receiving leased line data comprising:
- an unpacking unit which receives a DSL frame in which leased line data is packed and unpacks leased line data from the payload of the DSL frame;
- and
- a FIFO which stores the leased line data unpacked in the unpacking unit.
An apparatus for transmitting/receiving leased line data comprising:
- a FIFO which stored leased line data;
- and
- a DSL frame generating unit which comprises a packing unit which packs leased line data stored in the FIFO into a DSL frame payload, and an unpacking unit which unpacks leased line data from the DSL frame payload.
