  • 8 Mbps is the Lebanese Maximum Cap for DSL

Dear Users & Members,

Greetings :)

I would like to share this subject with you all to Understand the infrastructure of our DSL lines and the maximum speed can be provided.



http://en.wikipedia.org/wiki/ANSI_T1.413_Issue_2
First of all Our DSL Infrastructure is an "ANSI T1.413 Issue 2" which is Capable to provide 15 Mbps. However, because the data is split up into packets (actually Reed–Solomon encoded codewords) of 255 bytes, the maximum achievable downstream data rate is 8.128 Mbit/s (including other overheads).

That Means The Maximum we can get now is 8 Mbps.

http://en.wikipedia.org/wiki/ITU_G.992.5
But if Ogero Decides to upgrade the multiplexers around the areas we will be able to Have ADSL2+ ITU G.992.5 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2+ or ADSL2Plus. Commercially it is notable for its maximum theoretical download speed of 24 Mbit/s.

The Maximum Speed that can be Achieved by a Normal Copper Cable is 20 Mbps with ADSL2+

So All I Can say now is be happy with the 8 Mbps till we hope and beg for a Higher Speeds :) when Our Grandchildren Playing around us.

Remember: If we Had better Infrastructure they would've provided Higher than 6-8 Mbps Speeds. :/
Hi WiCkEd,

Changing equipment is not the only factor to achieve higher bitrates, your distance from the DSLAM is also a major factor.
Before changing their infrastructure they need to properly plan a deployment of their exchange to be closer to consumers, otherwise the investment does not make sense.
DSL Type on my router is "G.992.5 annex A". What does that mean?
I checked my DSL type which is with IDM and it is : ITU G.992.3 Annex A, which is ADSL2
a bit better than Ogero butstill need improvement
my problem is with the attenuation which is (up/down) 53/75
Noise 14/6.5

The ISP network (routers, connections) must also be able to handle the extra traffic.
I'm not saying it can't... just saying this is yet another potential bottleneck.
So all this previous talk about fiber-optics cables being installed resulting in the delayed speed was a sham?

We could have had those speeds since 2009, right?

You are right in principle, but the main reason not to have higher speed is that the main cables feeding lebanon with the internet were not enough to boost the speed, now after implementing the IMEWE cable they can provide it
