BT-Speeds75% of the lines in BT's trial are delivering > 300Mbps downstream and 30-50Mbps upstream, Trevor Linney told the Paris Summit. The majority of lines are less than 150 meters. 17% of the lines delivered between 200 & 300 megabits; 10% 100-200 megabits; 3%, 100 megabits.

38% of lines were < 100 meters; 35% 100-150 meters; 14% 150-200 meters. 8% 200-250 meters; 5% > 250 meters. Current systems are not delivering the goal of 300 megabits 300 meters but Trevor Linney is confident that improvements already on the way will bring BT close to the plan.



Hundreds of homes are connected, using DSLAMs from ADTRAN, Huawei, and Nokia. TalkTalk, EE, and other ISPs are participating. 

Linney notes that has changed considerably. 18 months ago, was only deployable at the DP. 96 port DSLAMs didn’t even feature on vendors roadmaps. We reported Huawei targets Q4 for 96 ports.


BT identified 5 key developments expected: 

  • Enable higher bits per tone (12>14)
  • Improve the receiver sensitivity (<-150dBm/Hz)
  • Increase the transmit power (4>8dBm)
  • Optimise the frequency usage with VDSL
  • Increased vectoring group sizes (>96)


212 GHz and cDTA are soon shipping from Adtran. True gigabit is here. Sales takeoff is almost in sight, probably Q1 2018.
Australia confirms 1M, AT&T is ready to ramp, DT finally is moving. Omantel and Telkom South Africa are now on the map. Almost all telcos are now choosing for large buildings when they don't go FTTH. MNet Cologne and Chunghwa Taiwan have changed from fiber all the way to in the basement.
