NBN FTTN question

[Exfso (Peter)]

I am expecting to be connected to FTTN in next week or so, my question:

I currently have ADSL2+ with a central splitter at the connection point. I am hearing conflicting opinions on whether this should be removed or not for the FTTN connection. As I believe this is essentially an ADSL filter, and with NBN the ADSL side will not be connected, so there is some confusion out there as to what is the best approach to take.
Any ideas on this much appreciated.

Your splitter will be removed. There​ is no more direct copper line, all voice is now VoIP.

Under NBN the old telephone wall sockets are no longer used....
You connect your phone to the new NBN router.
If you need additional phones then they need to be wireless with the master on the NBN router.

With FTTN your modem/router will be connected to your wall socket the same as the ASDL, but no splitter/ filter is needed or used with NBN and there is a phone socket on the modem which you plug your phone into. My modem has 2 phone sockets.

That's interesting. I have FTTN and my instructions were to continue using the old splitter/filter.

Paul,
As you can no longer connect your phone to the wall socket....... I don't know what benefit the splitter/filter would give.

[tlgerdes (Trevor)]

The splitter is used to restrict frequencies that your modem could use so that it did not interfere with your voice calls. As you are not using that spectrum for voice with FTTN you have effectively reduces your speed by about 10% by leaving the splitter in.

Peter, I am scheduled to cutover to FTTN this Friday, seven days after starting the process.

Will let you know.

Hi Ken,

On the face of it, I totally get what you're saying. I just went to look again at my setup and while the phone is connected to the VOIP outlet on the NBN router, the phone connection from the splitter/filter is connected to a PSTN connection on the router.

I'll have to read the manual again, but I might also have a play around with disconnecting that 'superfluous' connection and see what happens.

Noted Trevor. I'll remove mine this morning and check my speed. Initially speed was good, as promised, but as people have come across to NBN our speeds have dropped to approaching the old ADSL speeds while the few remaining ADSL users in the area who now have e torpedo to themselves are zooming along!

T'aint fair

Me to , I am expecting connection to NBN within a week .

I specifically asked as both my wife and me work and no one is home during the day and they ( Telstra ) said they do it all from outside .

My new Router is in transit as I type this , got confirmation via email a few days ago .

Thanks all. My splitter is hard wired, and to remove it I would need a new termination block to attach the NBN modem. My main reason for the question was to find out if it is going to have any derogatory effect by staying in place. I know that phone wise it will be from my modem which is of the voip variety.

If you're getting FTTN Brian, the nearest they'll come to your house is the torpedo tube down the road where they'll swap your wires from that to the new NBN box which will be somewhere near the old torpedo tube.

[PCH (Paul)]

For the record, I removed my splitter and just fed the wire from the DSL outlet on the router into the old wall socket.

It all fired up ok but no diff at all in terms of speed. No worries, I'm used to the crappy slowness now

Paul, how far are you from the node?

Ah, that's why the phone in our kitchen no longer works. It's connected straight to the wiring from outside.

I work in Telephony and my days are spent installing and troubleshooting PABX systems particularly with VOIP and FTTN & FTTP router installation and programming. There are a lot of misconceptions regarding NBN an VOIP, lots of urban myth and (inaccurate) hand me down statements from trained monkeys in carrier call centres.

Some older splitters are detrimental to higher speed Adsl signals and would be even more problematic with FTTN VDSL. There are specialty filters for VDSL but they have no application for FTTN.

Regardless, I would remove the filter, no great problem to do. I'd also disconnect all other wiring so that the VDSL connection to the FTTN router is as minimal as possible, i.e. no T junctions and or additional spurs past the router.

If you want to connect phones to the VOIP connection on the router then you can reconnect the disconnected house wiring to the VOIP port. (Ken's statement re additional phones having to be wireless is incorrect)

There are specialty VDSL filters available but as stated there is no reason to use one as there is no analog telephony signal or voltages on the line.

If your Modem/router is a self install be patient while waiting for sync, that can take in some cases up to 15 minutes, but most home grade routers will sync in a couple of minutes. Also some carriers have firmware in the routers that allows them to self configure, this can take additional time.

If you're porting your land line to VOIP there may be some downtime depending on the carrier.

Hi Phil, I am with IINet, so I get the router they send. As I said the central splitter was wired by a tech years ago when I got ADSL so to remove it, I would have to re terminate the cable to a suitable connector that I could connect my new Router to. Not sure of what to use and colour coding of plugs etc. Once the NBN is all connected, I will remove all my other phone connections in the house and use the phone connection on the back of the router, which is a voip I believe

About 300 metres give or take a bit Peter

Got notified by text early this arvo that nbn switch had occurred.
Connected successfully without splitter/filter
Gone from ADSL2+ at average 14Mb to 22Mb with NBN via Exetel, our original ISP.

Now just have to cancel PSTN and its goodbye big T for copper coms.
