What is the problem if the number of ADSL uplink frame errors is 100,000?

There is a problem with the line, there is a bad connection or aging place, the general line attenuation is too large, it will cause a serious phenomenon of wrong frames, 2m is the most common speed, even 6m should not be that situation. Line attenuation does not necessarily mean that there is a problem with the inlet line, but also the aging of the cable from the computer room to the transfer box or from the transfer box to the distribution box, resulting in increased line attenuation and line drop. You can just complain about this.

This is the total number of false frames recorded in the telecom equipment from the beginning of your Internet to the present, unless they clear it for you on the DSLAM device, otherwise the data will be higher and higher, and you can't handle it.

The general uplink behavior is 30 45, and the attenuation of your line is too large, and the reasons are generally:

1.If the line is too long, the longer the line, the greater the attenuation.

2.Poor wiring insulation.

3.The ring resistance between the lines is too large.

4.Line gas.

5.When the line is touched, a current is generated between the lines.

All of the above reasons require telecom personnel to check the line. Hit ** and let him check it.

In addition, what he means by reducing bandwidth generally refers to:

If the rate you apply for is 4m, but because the line is used for too long and the line is aging, the line will not run at all 4m, then Telecom will configure 4m on the template for you, then due to the line, the template configuration is high, and the wire will be often wired. I guess you have this reason, in this case, you have to replace the whole line, maybe the telecom side doesn't want to change it, so you want to reduce the rate.

If this has an impact on your internet speed, I suggest you go into your router and do a factory reset.

It can only be a problem of the entrance line or the direction of the office, generally speaking, this kind of problem, individual users can not solve.

Calculated by line rate.

At present, the ADSL we use is an asymmetric transmission method, that is, the uplink rate is not equal to the downlink rate; ADSL has an uplink rate of 640Kbps to 1Mbps and a downlink rate of 1Mbps to 8Mbps. The common is 2Mbps, note that the downlink rate is not equal to the ** rate, usually our ** software or air rush to tell the movie often can only reach 220kbps, not 2Mbps, in fact, 2M broadband is 2M bit (bit) instead of 2M byte (byte). According to the formula of 8 bits (bits) and 1 bytes, let's do the math:

2mbit 2048kbit 256kbyte, so theoretically, the maximum speed of 2m broadband should be 256k, and because of some other factors, the actual speed is normal around 200k. Judgment.

1. The Chinese name of ADSL is "asymmetric digital subscriber loop", which is a technology for broadband communication on ordinary ** lines. ADSL technology makes full use of the existing copper line resources to provide 640 kbps uplink and 8 Mbps downlink bandwidth on one twisted pair cable, thus overcoming the traditional user demand"The last mile"of"Bottlenecks", to achieve broadband access in the true sense. The transmission speed is 140 times faster than that of a normal modem.

ADSL adopts the connection mode of private line, and the ADSL modem is always connected to the network, eliminating the trouble of dial-up Internet access.

2. Therefore, in a practical sense, most of our users need mainly downlink, which is simply understood as the speed of browsing the web, etc., such as the speed of 2Mbps broadband at home The downlink rate is 200-240kb per silver old second per second, that is, the speed of ** to the machine;The uplink is the speed at which the upload speed is about 40-50kb per second, and the speed at which it is uploaded to other computers or servers. The front is rising.

3. The theoretical speed of this previous ** line is generally 4-5mbps. At present, it has tended to be eliminated, and it has become a trend of copper retreating, and the ADSL mode of the first line has been replaced by faster optical fibers. Dozens of optical fibers are set up with hundreds of mbps, which can be installed in ordinary homes.

The speed is very fast. Of course, the principle of asymmetry is still being implemented, that is, the bandwidth of 20 Mbps downlink is 2-3 Mbps in upload or uplink speed. But it's almost fast.

Broadband uplink and downlink refers to the uplink and downlink rates of general broadband or optical fiber Internet access, uplink is the speed of uploading from the computer, downlink is the speed of the host on the network, and the general downlink rate is relatively high!

The uplink and downlink rates of telecom broadband follow the following conventions:

1. For LAN or FTTH access broadband users

1) If the downlink rate is less than or equal to 4 Mbit/s, the uplink rate is 512 kbps

2) For broadband with a downlink rate greater than 4Mbps but less than 20Mbps, the uplink rate is 1Mbps;

3) For broadband with a downlink rate greater than or equal to 20Mbps but less than 100Mbps, the uplink rate is 2Mbit/s;

4) Broadband with a downlink rate equal to 100Mbps and an uplink rate of 4Mbps.

5) The downlink rate is equal to 200 Mbps of bandwidth, and the uplink rate is 10 Mbit/s.

2. For the broadband accessed by ADSL ADSL2+ VDSL, the uplink rate is 512Kbps.

ADSL (Asymmetric Digital Subscriber Loop) technology is a technology that realizes broadband access to the Internet with asymmetric digital subscriber lines, ADSL as a transport layer technology, makes full use of the existing copper line resources, and provides a bandwidth of 640kbps uplink (1Mbps theoretical uplink) and 8Mbps downlink on a pair of twisted pair cables, thus overcoming the traditional user in"The last mile"of"Bottlenecks", to achieve broadband access in the true sense.

The uplink rate generally refers to the speed at which someone else communicates from your computer!

Generally, the uplink and downlink rates of ADSL Internet access are asymmetrical, and the downlink rate of key Li is generally higher! The upside is relatively low! Now the normal is uplink: 386kb, downlink: 512kb!

Note that there is a difference between the rate and the actual speed! Generally, it needs to be divided by 8, so the actual speed is only about 50k! Transport socks.

Landlord, your access is 19M bandwidth? Cattle.

Your margin is greater than the attenuation, it is a problem with the quality of the line, which should be the cause of the wrong frame, first of all, you mention ** to listen to whether there is noise, if there is noise, then the line joint is best to be welded (there is noise, indicating that the line is in poor contact, it will produce impedance, which will lead to drops and slow network speed, as well as the problem of wrong frames) If there is no at all, then the line should be in good contact with the line itself, the impedance of the line itself is too large (such as aluminum core wire), or the line is too long or there is interference (such as passing through the large transformer on the pole, etc.). As long as the margin is greater than the attenuation at least half, it is normal.

Also, you change the access mode to (i.e., try it out. (This is the protocol used in the past, which only supports a maximum of 8m downlink and a maximum of 1m uplink, but it is very stable).

Your attenuation is greater than the margin, it is a problem with the quality of the line, which should be the cause of many reasons for the wrong frame, first of all, you mention ** to listen to whether there is noise, if there is noise, then the line joint is best to be welded (there is a noise indicating that the poor contact of the line will produce impedance, which will lead to dropped lines and slow network speed, as well as the problem of wrong frames) If there is no at all, then the line should be in good contact with the line itself, the impedance of the line itself is too large (such as aluminum core wire), or the line is too long or there is interference (such as passing through the large transformer on the pole, etc.).

Generally speaking, it is the normal loss of the line.

The rate of ADSL and the quality of the line are related to the distribution bandwidth, and the distance of 4m is generally about 4m km and 8m 2km.

The higher the distance, the shorter it is, and the easier it is to drop the connection.

Generally, more than 50k of 1m is the limit... The downlink rate of ADSL will not affect the uplink. The main problem is the line, and there are certain factors in the distance from the end of the bureau.

ADSL theoretical upload is 1M, but basically China Telecom Unicom Tietong is limited to 512K, that is, no more than 60K

The uplink speed is generally only 512K The same is true for optical fiber, but the speed of the optical fiber is relatively large, and it may feel faster, unless it is in the IDC computer room, the uplink can reach 1MB s, and our company directly accesses from the IDC computer room, and the uplink reaches 1M s This speed can only be done in the IDC computer room, that is, to do server hosting. But now we will implement broadband speed, fiber to the home, maybe it will soon be able to meet your wishes! Hope it helps.
