Heya guys

I recently upgraded my 4meg ADSL line to a 20meg VDSL line.

On the day of 'cut-over', my router stopped syncing to the ADSL2+ network (DSLAM0, and this sparked the first step at ripping out my ADSL router, and replacing it with a shiny new PACE router (yes I know its shyte, only found out about it after I purchased it).

So for the next couple of hours I could not get my PACE router to sync with the new VDSL network (I think it's called ISAM). Contacted the help desk, did line tests, and I was at the point (very disappointing point), of logging a line fault with telkom, when out of desperation, I replaced my ADSL filter, with the one in the PACE modem's box, and viola, it worked.

Just thought I share this with some of you guys, as I was under the impression that a filter is a filter. Boy was I wrong. So I guess the new VDSL network uses higher / lower frequencies to ADSL, and the filter filters all, except those frequencies?

Anyways, hope this helps the next guy.

I just upgraded to 20meg VDSL and what a pleasure. At first they just upped the line to 20meg ADSL2+. Phoned them and got it converted to VDSL. There is a huge difference in speed on both 20meg profiles. VDSL 2meg faster download. Of course less overhead.
 
Just so everyone knows:
You can use a VDSL filter on an ADSL line as well, been doing it for a couple of months, so if you need to replace the filter, look for a VDSL one so you won't have to get a new one if Telkom finally upgrades you.
 
hey i have a zyxel and no filter was provided in box...i did the same upgrade....and still having problems switching to vdsl line
 
Am I missing something, a filter is only needed if you plugging in a phone or fax machine. It doesn't do anything to the DSL port. You can plug your modem directly into the wall socket without a filter and it will work.
 
The only reason you install a filter is to cut out the interference/noise on your phone line . The VDSL/ADSL Connection can be plugged straight into your wall socket. The line normally will not sink with ADSL LINE if you plug the line into the wrong connection on the phone line filter.
 
Adsl 2+ can give you the 20mbs download speed but your upload speed is capped.
 
Is there any reliable way to check if it is better to use VDSL vs ADSL on 20mbps or can Telkom just switch the profiles relatively easy? i.e. in most cases it seems that ADSL on 20mbps seems to be more stable and since I already have a ADSL modem, why go through the expense of buying a VDSL modem and then possibly running into more issues (or always left wondering while on ADSL 20mbps if VDSL would be much faster).

VDSL is definitely worth it, If upload matters somewhat to you, that extra 1mbps will come in handy especially in your line of work connecting to vpns etc.

Also your SNR margins should improve on VDSL if they are low on ADSL2+

Awesome - thanks so much for the quick help from all. I will certainly get this done then. Hoping that this will be a seamless exercise.

I would recommend getting the Telkom Pace or the VDSL Zyxel router - Don't get the Netgear it's CR@P.

The pace you can return in 7 days if you aren't able to get onto a VDSL profile, once you've plugged in the Pace or Zyxel, it will sync at ADSL2+, Phone 10210, tell them you are on ADSL2+ and ask them to move you to VDSL profile. They should know what you mean and they'll ask you to reboot and it should be done.

oh, and don't use Afrihost if you sync higher than 10mbps, you are asking for trouble :D

Thanks. I was looking at the Asus DSL-N66U - anyone got feedback? I am would need to replace my Netgear N600 (Gigabit ports) so going back to 100mb LAN would not be fun (and I also don't want to stack up more kit).

Heard some reports about that Asus N66U malfunctioning quite often.

Got the N66U and configured it last night while still on ADSL/10mbps - with the latest firmware this modem router is awesome (compared to the Netgear DGNDv3700 I had) and has a ton of features (granted, some are meaningless such as downloader or media server). I was surprised to find that it also has WAN failover to 3G-USB stick which was not specifically mentioned.

Supposedly I am already switched to VDSL but still stuck in the office (sitting out loadshedding, sounds like a zombie-apocalypse outside) and will probably not be able to test out the router on VDSL tonight (unless Eskom gets the lights back by 9pm).
 
I have a question. I see you mentioned that ADSL and VDSL run on different frequencies. Does that mean if my ADSL exchange/DSLAM is currently congested, going to VDSL could solve that issue?

Thanks!

Frequencies won't matter on the backhaul side (in this case)...

Most of the older DSLAMs (ADSL) use the older ATM backhaul links.

All MSANs (VDSL) use metro-ethernet links.

So, in theory, it should solve your congestion issues.
