Internal Eir MTU

Charlie-Bravo

Having broadband installed - do I need to have the White main eir broadband/phone internal connection box on the wall seeing as eir are doing VoIP now?

What I'd like to do is wire the incoming line to a patch panel and then patch to the router via RJ11 socket. Is there any filter/regulator in those eir MTU boxes normally found in your hall?

What service are you having installed Astrofluff?

ADSL + FTTC/VDSL - you will still have a main termination unit (copper with a socket on the wall). Those can come with filters installed for phone/broadband

You could take the copper pair (as its landed in your home) to your own patch panel, and to a RJ11 installing either a NTU/filter on the eventual end point etc. but don't bet on getting any support should there be a line issue and Mr/Miss OpenEir come to the house to test the line from the house back to the street

FTTH - service doesn't touch any existing copper or doesn't need a line installed into a new house. There will be a ODP/ONT installed.
Have Eir started to sell VoIP with their fiber services yet or is that a (near)future plan?

Sounds like he's getting xDSL. Its an NTU not MTU(Max transfer Unit) btw.


- Running your own internals voids support from OpenEir technicians while setup that way
- You dont want your DSL on a patch panel if possible, its a big bridge tap. DSL should be taken off before
- Old bell wire that works for phones will hammer your sync, you need to be up to spec (CAT3 UTP) if you want anything reasonable.

Thanks for the input - the lingo is little beyond my knowledge. It is FTTKerb, then 600m of copper to the house. Black BT cable to an external box (ETU) where it connects to a CAT6A cable. Then the CAT 6A runs to a patch panel - are you saying I should have this NTU before the CAT 6A (or even the patch panel)? Could I do damage to my internal network by have the DSL running to the patch.

The service I have is not PSTN, its the VoIP service. Just learnt today that I cannot have my old phone number (PSTN) on the new broadband. Feeling quite annoyed with eir for not giving me the heads-up on that.

Yeah, so its FTTC or VDSL2.

In your scenario your router acts like a "joiner" of sorts. It creates the phone signal in its ATA and outputs that out the phone port on the rear.

What I'd like to do is wire the incoming line to a patch panel and then patch to the router via RJ11 socket.

I read this as External - Internal - Patch - Router before but I think you had it correct and I misread it.

It should be External - Router - Patch. If you've got CAT6 it doesnt matter if the router sits in between the external and internal cable or between the internal cable and the patch. The NTU is kind of irrelevant as the router will be the only thing directly interfacing with the line.

cheers ED...to give you a trusty MS Paint diagram...

ED E

Yup. Just make sure theres not too much untwist at any point. GigE with Cat6 you get away with murder but VDSL is a little more sensitive.
