This IP address 22.214.171.124 has been blocked for unusual usage patterns Keen to hear from anyone who has got a VDSL connection successfully working from a distance of 900m or more (from the cabinet). You can use the equivalent formula d = rt which means distance equals rate times time. To understand why noise exists we need to look at how traditional telephones work. The (potential) new place is, however, around 2400m from another exchange. ... May be bulldust to you but currently the only option available to the public to calculate approx distance to the exchange. However, the frequency potential of these wires is much higher and this led to the discovery of ADSL technology (Asymmetric Digital Subscriber Line). Looking for a VoIP plan? It may be possible you have a RIM/Top Hat closer which is like a sub-exchange, so your distance is based on the distance from that. Top … It checks Telkom’s systems for whether or not your phone line and area support speeds higher than 4Mbps or 10Mbps… To solve for time use the formula for time, t = d/s which means time equals distance divided by speed. The average distance from the exchange is 8.81km, the furthest is 12.2km. In adsl this may be reported as "loop loss" and is the natural deterioration of the adsl signal over distance from the exchange. Signal loss is much greater at the higher frequency's that VDSL uses and is also affected by increased power on longer lines. Keen to see how they benchmark against similar connections. ADSL2+ offers the best line speed (20Mb/s) up to 1Km from the exchange. If that's true, I'll send number as well. ADSL2+ offers the best line speed (24Mb/s) up to 1Km from the exchange. Re: How to calculate VDSL2 speed from Line Stats [ re: Colin_London ] [ link to this post ] Apologies - after writing a long post I realised I was being stupid as of course existing line stats have no bearing on the new performance from the (closer) cab location. Cheap price, bad customer service: Reasonable price, good customer service: Higher price, outstanding customer service : Total Votes: 14049 : VDSL is full line speed both ways, and is around 5x faster than ADSL for downloads, and approximately 10 x faster for uploads than ADSL. Upgrade from ADSL to VDSL - how long until download speed improves? Telkom ADSL speed upgrade on the cards. Similarly, ADSL2 can work up to 6km but you need to be no further than 1.5km to get 12Mb/s. ASDL takes advantage of the higher frequencies on the copper wire which are not used by voice. The ADSL connection/feed is done directly within the Exchange, with no changes to the PCP wiring. Similarly, ADSL2 can work up to 5.5km but you need to be no further than 1.5km to get 12Mb/s. Often, the term ‘VDSL2’ is also used. In general, the longer the total distance between your modem and the … You will be familiar with this noise when you hear crackling and noises on the line when making phone calls. (uk.telecom.broadband) Discussion of broadband services, technology and equipment as provided in the UK. Please read our article "How to improve broadband speed" for information on how to get the best speed from your Internet connection. Further speed upgrades for full fibre to 1Gbps (1000Mbps) are expected to be on sale later in 2017. This is commonly referred to as 'noise' and is explained at the end of this article.

This tool will immediately let you know if you should get your hopes up for a faster line. Fortunately this can be done instantly, online, by using the ADSL Checkertool on the Telkom website. There are devices that improve broadband signal quality and reduce noise - such as the micro-filters that many consumers have fitted in their homes. This is because the data is transmitted over copper wires (the same wires that are used for your phone calls) and the strength and quality of the signal transmitted along the copper wires degrades with distance. Note that is based on what VDSL is technically capable of and the setup here in NZ may give slightly different results. distance = rate x time. Been trying to calculate it based on ADSL stats, and creating a path to the exchange that matches the distance. Chart of Fibre Broadband (FTTC) Speed Versus Distance From the Cabinet. These characteristics of the copper wire directly contribute to the noise on the line and their effect is greater the longer the line. Unlike cable, broadband connections using ADSL broadband technology is distance-sensitive: the further you are from the exchange the slower the connection. The average distance from the exchange is 8.81km, the furthest is 12.2km. The FTTP products offer the same speed options as on FTTC (at the same price) and also faster versions at 100meg down /15 meg up, 110/15meg, 100/30meg, 330/20meg, and 330/30meg. The biggest factor that affects ADSL speed is your distance from your local telephone exchange. More of these frequencies are used for downloading data than for uploading - that's why it is called 'Asymmetric' DSL. ADSL service has a maximum distance of 18,000 feet (5,460 m) between the DSL modem and the DSLAM, though for speed and quality of service reasons, many ADSL providers place an even lower limit on the distance. ADSL and ADSL2+ are delivered to your home over copper wires, and because of this, the speed of your connection to the network is impacted by the distance the information needs to travel between the exchange and your home. Essentially, the standard ADSL can work up to 5.5km from the exchange. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. ADSL technology covers a larger distance than VDSL, where ADSL can cover 18000 feet, and VDSL can reach up to 4500 feet. Read Disclaimer First: This is an unofficial best estimate on both NBN technology and estimated speeds to act only as a guide and overview of the network/tech only. I enquired once with Orcon about getting VDSL and they told me that the increase in speed would be negligible as I was too far from the exchange. Hi I'm on a line that's right at the limit of FTTC/VDSL service - 3km, 39dB attenuation. DSL speed and copper length graph More on Telkom ADSL and VDSL. On the other hand, VDSL provides 55 Mbps downstream bit rate and 2.5 upstream bit rate. NBN MTM Alpha: Unofficial Tech/Speed Estimates. You can expect a throughput on a speed test 85% that of your connect speed - that would equate to ~17,746kbps / 2,218kBps. This decision was made because most users receive more data than they send. The most common one is BT iPlate which has been developed by BT and it has been proven by many consumers to speed up your ADSL connection. Oz Broadband Speed Test; Looking for a broadband plan? The VDSL equipment is installed in the cabinet and then the data sent back to the exchange … Time Entry Formats hh:mm:ss Discussions of specific services based on ADSL, cable modems or other broadband technology are also on-topic. Expected Speeds Here is a calculator for expected VDSL speeds vs distance *1. Origin shows what speeds VDSL2 can achieve Saturday, April 7, 2012 10:21 AM; 68 comments; Digital Region broadband providers are ensuring they are not left behind in the speed competition, as Origin Broadband has announced the details of its faster than 40 Mbps service Origin Max. My question is: Does the distance from an exchange has a significant impact on the speed? The average distance from the exchange is 8.81km, the furthest is 12.2km.
