Desi Cartman Posted June 23, 2011 Posted June 23, 2011 What Sree is saying a common excuse given by ISPs in Aus for slow internet speed
IKnowU Posted June 23, 2011 Posted June 23, 2011 What Sree is saying a common excuse given by ISPs in Aus for slow internet speed It is true though. Australia has such a vast coverage area with piss poor demand for it. Hence the exchanges are usually only located around the high density areas. And most of all people are more then happy to get ripped off by the bs prices for the internet and other services. :headshake:
mishra Posted June 23, 2011 Posted June 23, 2011 Dont you question peoples imaginations. Thats my boss
ganeshran Posted June 23, 2011 Posted June 23, 2011 My ISP told me the same thing - that for a 4Mbps connection, my house should be within 2 kms of the DSLAM . Was it a lie? :mad:

Was it a lie? :mad: http://en.wikipedia.org/wiki/Digital_Subscriber_Line_Access_Multiplexer is a decent article... Copper wire length do matter. Unless they are using one copper wire from your home all the way to exchange i seriously doubt its copper wire... But vc,pvc and vp are independent.. Just my guess, ...I suspect them guys at exchange dont want to fiddle with configuration.So every within 2KM are effectively on one set of slots in DSLAM. All the rest are being accommodated on others... Also they are probably configuring too many vcs per slot/port

Just my guess, ...I suspect them guys at exchange dont want to fiddle with configuration.So every within 2KM are effectively on one set of slots in DSLAM. All the rest are being accommodated on others... Also they are probably configuring too many vcs per slot/port I saw this on wikipedia. It says the same thing my ISP told me - that the bandwidth offered depends on the distance between my home and DSLAM. Balanced pair cable has higher attenuation at higher frequencies, hence the longer the wire between DSLAM and subscriber, the slower the maximum possible data rate. The following is a rough guide to the relation between wire distance (based on 0.40 mm copper) and maximum data rate. Local conditions may vary, especially beyond 2 km, often necessitating a closer DSLAM to bring acceptable bandwidths: 25 Mbit/s at 1,000 feet (~300 m) 24 Mbit/s at 2,000 feet (~600 m) 23 Mbit/s at 3,000 feet (~900 m) 22 Mbit/s at 4,000 feet (~1.2 km) 21 Mbit/s at 5,000 feet (~1.5 km) 19 Mbit/s at 6,000 feet (~1.8 km) 16 Mbit/s at 7,000 feet (~2.1 km) 8 Mbit/s at 3 km 1.5 Mbit/s at 15,000 feet (4.5 km) 800 kbit/s at 17,000 feet (~5.2 km)
EnterTheVoid Posted June 23, 2011 Posted June 23, 2011 Mishragreat, did you catch that bit about Internet speed vs distance you knob or are you busy overdosing on smileys again?
Holysmoke Posted June 23, 2011 Posted June 23, 2011 You guys are talking about copper. Most places use fiber now.

ganeshran Posted June 23, 2011 Posted June 23, 2011 You guys are talking about copper. Most places use fiber now. Maybe Airtel still uses copper in my area. :dontknow: Also areas in madiwala which have a closer DSLAM get the 4mbps plans but I dont. :wall:
DomainK Posted June 23, 2011 Posted June 23, 2011 My ISP told me the same thing - that for a 4Mbps connection, my house should be within 2 kms of the DSLAM . Was it a lie? :mad: Thank God I was never fed such BS.
EnterTheVoid Posted June 23, 2011 Posted June 23, 2011 Fibre optic? Naaaaa I am still on copper. The only place I know that uses fibre optic are my work place.
ganeshran Posted June 23, 2011 Posted June 23, 2011 Thank God I was never fed such BS. Is that wikipedia article wrong which I posted few posts back? Also there is no need for Airtel to lie about it to me. the 4mbps plan costs more than what I am paying now. What would be their incentive to deny me a higher end plan?
EnterTheVoid Posted June 23, 2011 Posted June 23, 2011 Ganesh, the further you are from the exchange, the slower you speed. That's just the general rule.
