However, to get 8Mbit you would need to be located no further than 2km 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. Note that is based on what VDSL is technically capable of and the setup here in NZ may give slightly different results. Even with noise on the line that causes you to miss some of the words you can still understand the conversation. 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. First thing’s first: check what Telkom says your maximum supported line speed is. 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. My question is: Does the distance from an exchange has a significant impact on the speed? Discussions of specific services based on ADSL, cable modems or other broadband technology are also on-topic. Distance from the exchange plays a big role in potential VDSL speeds. ADSL2+ offers the best line speed (20Mb/s) up to 1Km from the exchange. If your home is within 750 to 900 meters of the VDSL enabled local roadside cabinet then VDSL should work for you. Where you can get Telkom 40Mbps VDSL, 100Mbps FTTH However, to get 8Mbit you would need to be located no further than 2km from the exchange. Fiber optic cable is being built around the country and the old rural ADSL DSLAM stations are turned into VDSL2 if possible (within reasonable distance from the telephone exchange). Further speed upgrades for full fibre to 1Gbps (1000Mbps) are expected to be on sale later in 2017. The biggest factor that affects ADSL speed is your distance from your local telephone exchange. 17 May 2020 by Dr Mark Heath ‘Fibre broadband’, or Fibre-to-the-Cabinet (FTTC) as it is more formally known, is the technology that delivers the vast majority of superfast broadband connections in the UK currently. Cheap price, bad customer service: Reasonable price, good customer service: Higher price, outstanding customer service : Total Votes: 14049 : Hi I'm on a line that's right at the limit of FTTC/VDSL service - 3km, 39dB attenuation. Some users have maximum of 40/10 as of 2016, due to EstWin project. Expected Speeds Here is a calculator for expected VDSL speeds vs distance *1. Copper wires are used to transmit voice calls using the frequencies up to 3400 Hertz. ... May be bulldust to you but currently the only option available to the public to calculate approx distance to the exchange. The £35.50 per month service will run VDSL2 at the fastest possible speeds, so while some will … I would gladly pay for 50mbit even if my line only ever sync'd at ~45. In general, the longer the total distance between your modem and the … Been trying to calculate it based on ADSL stats, and creating a path to the exchange that matches the distance. speed = distance/time. Similarly, ADSL2 can work up to 6km but you need to be no further than 1.5km to get 12Mb/s. Even if your local cabinet is VDSL capable, distance is still a factor. The VDSL equipment is installed in the cabinet and then the data sent back to the exchange … To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. This tool will immediately let you know if you should get your hopes up for a faster line. The average distance from the exchange is 8.81km, the furthest is 12.2km. To understand why noise exists we need to look at how traditional telephones work. In relation to broadband, what is of highest priority to you? Upgrade from ADSL to VDSL - how long until download speed improves? Calix customers leverage our intelligent software platforms and cloud analytics to transform and optimize their business models, rapidly deploy new services at DevOps speed, and make the promise and opportunity of the smart home and business a reality. The average distance from the exchange is 8.81km, the furthest is 12.2km. 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. So still straight-through the PCP.-----For most VDSL connections, the equivalent to the ADSL Exchange equipment is provided in the (new) FTTC, with Fibre from the Exchange (or even another Exchange) providing a multi-path, high speed link to the Web. Advertising is not allowed. This IP address 52.191.163.105 has been blocked for unusual usage patterns From May 1, 2013, VDSL2 is also offered to private customers with speed 30/10. That sounds like a pretty accurate description from Slingshot. This decision was made because most users receive more data than they send. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed. Similarly, ADSL2 can work up to 5.5km but you need to be no further than 1.5km to get 12Mb/s. ADSL technology covers a larger distance than VDSL, where ADSL can cover 18000 feet, and VDSL can reach up to 4500 feet. 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 graph above shows how distance from the exchange affects line speed for ADSL (max 8 Mb/s), ADSL2 (12 Mb/s) and the latest ADSL2+ (24Mb/s). Whilst attenuation is normally directly linked to the length of your line, there are a few other important factors to bear in mind as to why the above calculator can only be used as a guide. Distance from the exchange isn't the only reason your broadband speed may be slow - the quality of wiring in your house, number of people sharing the broadband infrastructure on your street, and interference from electrical equipment will also contribute. I'm thinking the copper might loop around the street, if so I'm pretty screwed in terms of distance, even if the pillar is only around 70m from the house. It checks Telkom’s systems for whether or not your phone line and area support speeds higher than 4Mbps or 10Mbps… Oz Broadband Speed Test; Looking for a broadband plan? Top … Unfortunately, digital communication does not tolerate missing data and any missing information has to be re-sent and these delays reduce your download speed. Got a customer who is beyond the 900m mark but their line noise is in the 9-10 range. Essentially, the standard ADSL can work up to 5.5km from the exchange. The BroadbandExposed telephone exchange search tool quickly maps the location of your nearest telephone exchange. On the other hand, VDSL provides 55 Mbps downstream bit rate and 2.5 upstream bit rate. (uk.telecom.broadband) Discussion of broadband services, technology and equipment as provided in the UK. DSL is a distance-sensitive technology: As the connection's length increases, the signal quality and connection speed decrease. More of these frequencies are used for downloading data than for uploading - that's why it is called 'Asymmetric' DSL. Keen to see how they benchmark against similar connections. VDSL can support asymmetric as well as symmetric data and POT services while ADSL supports only asymmetric data and POT services. Chart of Fibre Broadband (FTTC) Speed Versus Distance From the Cabinet. time = distance/speed. In adsl this may be reported as "loop loss" and is the natural deterioration of the adsl signal over distance from the exchange. ADSL2+ offers the best line speed (24Mb/s) up to 1Km from the exchange. If you are 8KM from the main exchange it is almost certain that their is one between you and the main exchange however a closer one may have been installed but there is the chance that no nothing has changed. If that's true, I'll send number as well. Looking for a VoIP plan? Poll. You can expect a throughput on a speed test 85% that of your connect speed - that would equate to ~17,746kbps / 2,218kBps. I guess you need to be 300m or closer to safely get 50mbit. The ADSL connection/feed is done directly within the Exchange, with no changes to the PCP wiring. 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 hear from anyone who has got a VDSL connection successfully working from a distance of 900m or more (from the cabinet). Ceasing VDSL and providing ADSL instead - what's involved by BT?

You can use the equivalent formula d = rt which means distance equals rate times time. NBN MTM Alpha: Unofficial Tech/Speed Estimates. About the SG DSL Speed Calculator The SG DSL Speed Calculator is a tool for quick estimation of the maximum attainable ADSL/ADSL2+/VDSL sync speed based on signal attenuation. Unlike cable, broadband connections using ADSL broadband technology is distance-sensitive: the further you are from the exchange the slower the connection. FAQ: Unusual access. Distance to the cabinet from your home. However, the frequency potential of these wires is much higher and this led to the discovery of ADSL technology (Asymmetric Digital Subscriber Line). I also can't believe how quickly VDSL drops over distance. 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. All online ADSL checkers I've seen give either rather vague estimates of 1Mbps speed for all the properties, or no result at all, whereas in reality the best speed I've heard of is 2.5Mbps, while most seem to get less than 1Mbps, and the furthest houses cannot get This is commonly referred to as 'noise' and is explained at the end of this article. Currently Active Users Viewing This Thread: 1. To use the calculator simply fill in the downstream attenuation number (dB) from your DSL modem, and all other values will be calculated automatically. Telkom 20Mbps ADSL2+ service launched. BT HomeHub won't sync at all, but my Vigor 2860 just manages. 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. You will be familiar with this noise when you hear crackling and noises on the line when making phone calls. Often, the term ‘VDSL2’ is also used. These characteristics of the copper wire directly contribute to the noise on the line and their effect is greater the longer the line. 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.

User #395957 2772 posts. There’s method to the madness here. All online ADSL checkers I've seen give either rather vague estimates of 1Mbps speed for all the properties, or no result at all, whereas in reality the best speed I've heard of is 2.5Mbps, while most seem to get less than 1Mbps, and the furthest houses cannot get Telkom ADSL speed upgrade on the cards. 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. How fast is VDSL? ASDL takes advantage of the higher frequencies on the copper wire which are not used by voice. The (potential) new place is, however, around 2400m from another exchange. DSL speed and copper length graph More on Telkom ADSL and VDSL. Time Entry Formats hh:mm:ss Fortunately this can be done instantly, online, by using the ADSL Checkertool on the Telkom website. The impact of distance from exchange on the ADLS2+ speed Hi all, I am considering moving out of my current home, which is around 935m from the Telstra exchange. 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. There are devices that improve broadband signal quality and reduce noise - such as the micro-filters that many consumers have fitted in their homes. The average distance from the exchange is 8.81km, the furthest is 12.2km. There is no affiliation with NBNCo, and is only an enthusiast site trying to bring visibility to what's being deployed.
