Embodiment Construction

[0018] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] The purpose of the present invention is to solve the problem that the connection cannot be established due to the loss of synchronization between the wire pairs in the DSL multi-wire pair mode.

[0020] FIG. 1 is a block diagram of a multi-pair DSL equipment detection and processing apparatus according to an embodiment of the present invention. As shown in Figure 1, the multi-line pair DSL equipment detection and processing device of the present invention includes: a detection unit 102, which is used to detect the link status of each physical port of the multi-line pair DSL equipment; When the detection unit detects that one or more links of the physical ports of the multi-pair DSL device are faulty, it resets the corresponding physical ports of the multi-pair DSL device to re-establish the link.

[0021] In the multi-line...

Abstract

The method includes following steps: step S202 detects link state of each physical port in DSL device with multiple line pairs; when one or multiple links in physical port of DSL device with multiple line pairs occur fault, step 204 resets corresponding physical port of DSL device with multiple line pairs in order to restart link building. The invention effectively solves issue that under mode of DSL multiple line pairs, link cannot be built for long time caused by synchronization loss between line pairs.

Description

technical field [0001] The invention relates to the communication field, in particular to a device and method for detecting and processing multi-pair DSL equipment. Background technique [0002] DSL is a widely used access technology. Usually, the central office (CO) and the customer end (CPE) of the DSL are connected through a twisted pair. The most common is to use a 1-pair twisted-pair connection, such as the widely used ADSL. In addition, some DSL technologies support the use of multiple pairs of twisted-pair connections, such as SHDSL, which can work in 4-wire (2 pairs of twisted-pair) mode. [0003] In the multi-pair mode, the user ports on the DSL line card at the central office or the DSL modem at the user end are also bundled and used. At this time, this group of ports can be regarded as a logical user port. [0004] Taking the SHDSL4 wire mode as an example, two pairs of twisted-pair wires work together in normal operation to jointly undertake data transmission....
