Abstract
The method includes the following steps: a detecting unit is set at central office used for detecting the state of ADSL port, if the ADSL port is at the state of HANDSHAKE, the detecting unit sends the information about ADSL port to the control chip, the control chip sends out the instruction of restarting the ADSL port; after the ADSL port receives the instruction of restarting, the ADSL port is restarted.
Description
Technical field:
The present invention relates to a kind of method of evading adsl port can't be synchronous.
Background technology:
ADSL (Asymmetrical Digital Subscriber Loop, asymmetric DSL) is used on the copper twisted-pair feeder transferring voice and data simultaneously, is based on a physical transfer layer protocol of unshielded twisted pair medium.ADSL is applicable on a pair of common multiple twin local loop, and plain old telephone service (POTS) and a series of digital channels are provided simultaneously.Wherein digital channel is asymmetric speed: the network local side to the user side to, high down high speed channel and duplexing low rate channel to 6-9Mbps can be provided, and the data uplink speed of 800Kbps and the speech bandwidth of 4KHz in the opposite direction only are provided.Because ADSL has many characteristics such as asymmetric, that transmission range is long, antijamming capability is strong, become the mainstream technology of broadband access at present gradually.
Adsl port is a Transmit-Receive Unit minimum in the broadband network equipment, and each port can provide one road ADSL broadband to insert for the user.The local side adsl port corresponding with the user has IDLE, HANDSHAKE, four kinds of states of TRAINING, DATA.When closing, adsl port is in the IDLE state; Can be in the HANDSHAKE state after opening adsl port, be connected with ADSLMODEM, can enter the TRAINING state and shake hands up to successfully entering the DATA state, just this moment can the normal transmission data as far-end.
Because the ADSL technology is quite ripe, it has in the industry cycle had standard, and is accordingly, also many according to ADSL MODEM brand, the kind of this standard design.But, because local side chip some differences on agreement is understood that the MODEM of some brands and broadband network equipment are specific, in the practical application, the local side port is with after the MODEM of some brands cooperates operation for a long time, the local side port status can occur and rest on the HANDSHAKE state always, not to TRAINING state transition, thus the problem that generation local side and user can not be synchronous.
Summary of the invention:
At the existing problem and shortage of above-mentioned existing adsl communication method, the purpose of this invention is to provide a kind of method of evading adsl port can't be synchronous.
The present invention is achieved in that a kind of method of evading adsl port can't be synchronous, may further comprise the steps:
At local side detecting unit is set, is used to detect the state of described adsl port;
If described adsl port is in the HANDSHAKE state, described detecting unit sends to control chip with this adsl port information, and described control chip sends the instruction of restarting this adsl port according to described adsl port information;
After described adsl port receives the instruction of restarting of described control chip, restart this adsl port.
Further, described detection adsl port is specially the repeating query detection in batches of all adsl ports of local side.
Further, described adsl port information comprises the ID and the state information of ports having.
The present invention is used for regularly detecting the operating state of local side port by increasing special detecting unit, if be in the HANDSHAKE state, just periodically carry out close, open operation, can evade falling the purpose that adsl port can't be synchronous thereby reach.Because the synchronous port status of local side port and far-end MODEM is DATA,, can not have influence on the port that the user uses, transmitting data certainly so detection of the present invention can not have influence on the port that is in synchronous regime yet.And local side apparatus especially rack-mount unit have a lot of ports, for fear of concentrating operation in enormous quantities to cause that the conflict of resource aspect, the present invention adopted the small lot time segment mechanism handled of monitoring in turn.
Description of drawings:
Below in conjunction with accompanying drawing, the present invention is made detailed description.
Fig. 1 is an application state schematic diagram of the present invention.
Embodiment:
As shown in Figure 1, when the present invention uses, between broadband access switch and user, directly couple together and get final product by ADSLMODEM.The present invention is used for the access interface on the broadband access switch is monitored by increase detecting unit on the broadband access switch, has also promptly increased the operating state that special task is used for regularly detecting the local side port in software systems.Be in the HANDSHAKE state if detect certain port, not to TRAINING state transition cause can not be synchronous problem, if, can normally use it to this port is restarted.Therefore the present invention is by being in HANDSHAKE in case detect certain port, immediately to control chip report testing result, control chip is according to the ID address of this port, send reset command to this port, port restarts and enters HANDSHAKE, TRAINING, DATA state successively, recovers the normal use of port.This process is fast rapid.
Broadband access switch especially rack access switch generally has a lot of ports, for fear of concentrating operation in enormous quantities to cause the conflict of resource aspect, the present invention adopts the small lot time segment mechanism of monitoring processing in turn, promptly only detect the fraction port at every turn, and detect other ports successively, the whole detection deadline is its minimum period, regularly port is detected.
Use for convenient, but the present invention also is provided with the switch of On/Off measuring ability, the present invention also can set up on their own sense cycle.
The present invention's application process on certain broadband access switch is as follows:
Config detect on|off On/Off monitoring function;
Config detect period＜1～720〉monitoring periods (unit for minute) is set.
For convenient testing result is got information about, the present invention also can export testing result by display:
Show detect information shows monitoring state and relevant information.
Claims (3)
1. method of evading adsl port can't be synchronous is characterized in that this method may further comprise the steps:
At local side detecting unit is set, is used to detect the state of described adsl port;
If described adsl port is in the HANDSHAKE state, described detecting unit sends to control chip with this adsl port information, and described control chip sends the instruction of restarting this adsl port according to described adsl port information;
After described adsl port receives the instruction of restarting of described control chip, restart this adsl port.
2. the method for evading adsl port can't be synchronous as claimed in claim 1 is characterized in that, described detection adsl port is specially the repeating query detection in batches of all adsl ports of local side.
