[off] Bezeq NGN - good or bad?

2009-10-14 Thread Ira Abramov
my fellow sysadmins - Nezeq just called one of my client offering an
upgrade from 5000/500 to NGN 1/800. They say it only takes a sec as
their router is compatible. Is it stable and safe by now? should one
make the switch?

Offlist replies appreciated, though I thought it may be of interested to
others, based on past experience :-)

If it only takes a second, they already have it. Sometime in the past,  
when they were not looking, BEZEQ changed their connection to NGN, but  
left the old speed settings. Unless there is some hidden instability  
in the router, it should be exactly the same, except occasionaly faster.


What I have found having two lines, one aDSL, one HOT with two  
different ISP's is that the download/upload speeds outside of Israel  
are influeneced by more factors than just connection speed. With a few  
exceptions, they both seem to connect to the same sites at the same  
throughput. What is limited by the line speed is the agregate speed. I  
may be able to get 150k bytes per second from one site at a particular  
time of day, but I can get two connections to two diffferent sites on  
the 2.5m line and four on  the 5m.

AFAIK, once you're upgradable by a click to NGN, technically you already
sit on an NGN fiber, i.e. the other end of your DSL line is the NGN box
which now provides DSL/POTS over Bezeq's IP network [this is based on
official press releases].

Hence, you're already using NGN (did you notice a prolonged loss of DSL line
a while back? that was the conversion) - it's merely a bandwidth upgrade.
Assuming the SnR between you and the new box is OK, higher bandwidth should
not be a problem. Can your ISP supply the demand, especially to traffic
outside the borders of Israel? Good question.

HTH,

hi Ira,

We recently switched from 2mb/0.5mb to 2mb/2mb everything was promised to run 
smoothly, but in effect after the upgrade they found out that there was noise 
on the line and they had to connnect an additional two wires to get it to 
work

After 3 hours I asked to stop the upgrade and put us back on the old hardware, 
they said it was too late as they already upgraded us, and were now fixing 
the issue.

It took them an additional 7 hours to get everything to work

So my experince is that they want it to go smoothly, but expect it to not, as 
it didn't with us.

We recently upgraded from 5000/500 to 8000/800.  I don't know if we're 
using this NGN thing, but the line did have to go down for a little while 
while they made the change.  Is there any way I can tell whether or not 
we're using NGN, short of calling them to ask?


In the case that we are using it, it's been just as solid as the 5000/500 
connection we ad previously (i.e. pretty solid).


The change was a couple of months ago.

Not sure how often we get the full down, but it's definitely made a 
difference in the outgoing trafic throughput.


Geoff.

NGN as I understand is mainly for Symetric non-ADSL type solutions - i.e.
fiber and SDSL

Meaning that 8000/800 is probably still in the ADSL area.. but I might be
wrong

 NGN as I understand is mainly for Symetric non-ADSL type solutions - i.e.
 fiber and SDSL


Not only they have no Symmetric packages offered on their website for the
NGN world, all their Asymmetric packages still have ridiculous upstream
bandwidth as ever. For example 30Mbit/s down with... 1Mbit/s up. Sometimes I
even wonder if this upstream is fast enough to sustain all the TCP ACKs for
a 30Mbit/s download :(

Of course, I doubt this is an NGN limitation. If we would have a FiOS[1]
equivalent bandwidth, like 50Mbit/s down and 20Mbit/s up... how could they
sell a lousy 2Mbit/s up/down E1 for thousands of shekels every month?

Hi,

The NGN site is promotional information and has no relevance to the
hardware/equipment

so I would take any information written there as promotional and nothing
more

I don't know about whether or not 3/1000 will even work, but if someone
gets that and tries to use that for uploading he will be shocked to find
out you can't get both at the same time

NGN is simply FTTC (Fiber to the Curb).  At the curb, they put in a DSLAM that 
converts the fiber to ADSL2+ or VDSL.  ADSL2+ is already active on 8mb 
connections; most of the modems they have been passing out in the last few 
years are ADSL2+ compatible.  ADSL2+ has a maximum of 24mb down / 1.4mb up 
(theoretically in ideal line conditions). Since they can't guarantee perfect 
line conditions (and upload is more sensitive to attenuation), they cap it at 
800mb up.  Eventually, when they want to go above these limits to their up to 
50mb download speeds they are advertising, you will have to change out your 
modem for VDSL or VDSL2. VDSL modems can handle up to 100mb upstream as well, 
so that will be when you see better upload performance.

BTW In Australia ADSL2+ is pretty standard in the urban areas (the
bush is a completely different story), with large caveats about
distance from exchange.
Annex M is claimed to increase ADSL2+ upload speed to 2Mb/sec,
becoming more and more wide-spread.

For a symmetrical link at our office we use SHDSL, have 3M/3M now, can
upgrade to 4M/4M at a small extra cost.
