Problems solved by technology

[0004] It is not difficult to see that the bandwidth of interface 1 of the DSL subscriber board using the above technology is limited, which limits the user bandwidth and user density of the subscriber board, which is not conducive to reducing costs and developing new services with greater bandwidth requirements in the future
At the same time, only one interface 2 in working state results in limited bandwidth of the uplink interface on the DSL user board, which also limits the improvement of user bandwidth; Except for backup and protection functions, there is no improvement in interface bandwidth, so user density and bandwidth still cannot be improved

Embodiment Construction

[0019] The core idea of ​​the present invention is: because the bandwidth of the interface between each chip in the DSL user board directly affects the processing bandwidth of the user board. Therefore, the present invention realizes the improvement of the processing bandwidth of the DSL user board by increasing the bandwidth of the interface between each chip of the DSL user board. The bandwidth promotion can increase the number of users of the DSL user board, thereby effectively reducing the cost, and the increase of the bandwidth can also increase the bandwidth of the DSL user board. bandwidth to adapt to the future development of DSL high-bandwidth technology.

[0020] The DSL user board includes the interface between the DSL physical interface chip and the protocol processing chip, and the interface between the protocol processing chip and the uplink physical interface chip. Therefore, the present invention improves the broadband of these two interfaces respectively accord...

Abstract

The invention discloses an improving DSL user board bandwidth method, which raises interface bandwidth between DSL user board chips to the scheduled bandwidth according to the bandwidth value which needs to improve, when the DSL user board bandwidth needs to improve. The invention comprises the following modes: increasing interface quantity; improving interface broad band rate; or improving interface clock frequency. The invention can improve processing bandwidth of DSL user board, which reduces the cost.

Description

technical field [0001] The invention relates to DSL (Digital Subscriber Line) technology, in particular to a method for increasing the bandwidth of a DSL subscriber board and a DSL subscriber board using the method. Background technique [0002] At present, DSL technology is widely used, and the requirements for DSL subscriber boards are getting higher and higher. The port density of subscriber boards ranges from 8, 16, 32 to 64, or even higher, and the bandwidth of DSL lines varies from 512K, 2M, 8M, 24M To even higher 100M, in order to comply with the above-mentioned development trend, the processing bandwidth of the DSL user board must also be rapidly improved. [0003] At present, the structure of most DSL user boards is as follows: figure 1 As shown, there is only one interface (interface 1) between the DSL physical interface chip and the protocol processing chip, with UTOPIA (asynchronous transmission universal test and operation physical interface) Level1 (first type...
