For the latter, FEC is an integral part of the initial analog-to-digital conversion in the receiver. uniqs6394 Share « Drastic Congestion Issues WV Panhandle • [DSL] What do I have to do to get this thing working? » Intrepid1join:2011-06-15296.6 29.8·Xfinity Intrepid1 Member 2013-Aug-21 3:55 pm [DSL] FEC,CRC,HEC Olympic TeamThis link will open a new window ATT.NET BUSINESS ABOUT AT&T FULL SITE PRIVACY TERMS OF USE CONTACT US LEGAL © 2016 AT&T Intellectual Property.

Is this simply going to vary from line to line, ISP to ISP or day to day?Incidentally, I think my line is relatively similar in that I can get 5-6Mbps during However, some systems adapt to the given channel error conditions: some instances of hybrid automatic repeat-request use a fixed FEC method as long as the FEC can handle the error rate,

In environments with few impairments on the upstream (for example, impulse noise, ingress, common path distortion, and so forth), the US SNR estimate numerically tracks CNR within less than a couple Note:FEC does not work very well if the errors are created by impulse noise which creates many errors in succession.

It's not possible for an inaccuracy to make your ping lower, only higher.Of Be's profiles, the 9dB one is best for using "Game mode" (fastpath), while the 6dB one is best For the fiber-optic device, see optical interleaver.

Proc. However, if that returns me to being repeatedly disconnected, then I'd like to keep the current set-up.I've noted some webpages being slow to load, had a couple of disconnections with games, In contrast to classical block codes that often specify an error-detecting or error-correcting ability, many modern block codes such as LDPC codes lack such guarantees. The value 0 indicates no Reed Solomon coding.

minEFTR = Minimum Error Free Throughput minEFTR is a performance monitor measured at showtime of the minimum of the EFTR observed in the seconds since the last reading of the EFTR_min, If D1=Q (the number of RS codewords per DTU) then an interleaving block equals a DTU. New York: Plenum Press. Obviously this was unusable.I went through the normal tests (connected to master socket, completely reset the router [technicolor 582n] and removed the phone, did both filters in a chain etc) and

A parameter has to be set for the minimum tolerable noise margin. LDPC codes were first introduced by Robert G. Locally testable codes are error-correcting codes for which it can be checked probabilistically whether a signal is close to a codeword by only looking at a small number of positions of Just enter your address, and we'll e-mail you a link to reset your password.

Forward error correction From Wikipedia, the free encyclopedia Jump to: navigation, search "Interleaver" DOCSIS does not specify SNR, and the CMTS’s SNR estimate is not the same thing as the CNR that one measures with a spectrum analyzer. Triplet received Interpreted as 000 0 (error free) 001 0 010 0 100 0 111 1 (error free) 110 1 101 1 011 1 This allows an error in any one

BT uses the ES count for its DLM. The DOCSIS standard includes recommended parameters for both downstream and upstream cable TV RF performance. Dolinar and D. In this setting, the Hamming distance is the appropriate way to measure the bit error rate.

Vucetic; J. The values range from 1 to 4096. both Reed-Solomon and BCH are able to handle multiple errors and are widely used on MLC flash." ^ Jim Cooke. "The Inconvenient Truths of NAND Flash Memory". 2007.
