PSTN with PBX advice please!

Just trying to help out a friend who has an old internal analogue PBX system hanging off a single analogue line...

They currently have ADSLMax on that line all working fine but BT say that fibre cannot be enabled....

All a bit vague - but should there any technical reason why not? BT Checker says Yes, and predicts a lovely full fat 80 for fibre, but BT humans say no...

Many thanks!

Are they saying FTTC can't be ordered because of the PBX?

It's looking that way - but there may be crossed wires (!) - I'm going to end up speaking to them myself methinks...as I think my friend gets baffled by BT each time they attempt to get further...

I presume, due to there already being ADSL Max on the line, that there is already an NTE with a faceplate ADSL filter fitted on the feed before the PABX switch ?

If so, then this is a doddle for anyone to fix.

No physical reason why the line cannot be used for FTTC, more than likely that some 'marker' on the line creates a 'computer says no' scenario.

That's what I was thinking

Yep - faceplate and filter before PABX ...

Thanks for the sanity check

No probs, now all you have to do is persuade, politely, a CP to order the service.

Good luck.

Would an earth calling PBX still work with FTTC or would the line length from the cab to exchange be too long? If so this could be the problem if the PBX is that old. That is the only thing I can think that would show on the BT side.

In all honesty, I don't know.

It must be ten plus years since I worked on an earth calling line !

Would ADSL function on an earth-calling line?

That's another 'pass' from me, technically I can't think why not, and maybe that's the answer for if FTTC would work also ???
