Re: fttp 300/30 delivering 160/30


[re: shortshrift27] [link to this post]
 
This was resolved this morning with the following note: "BT Complex fault team has updated that there was issue with VLAN associated with the circuit from supplier end and they have moved the VLAN from their side for given circuit and hence request you to please retest the circuit speed..."

After 2 1/2 weeks, the 160 Mbps cap has lifted!

(And I can see from my TBB BQM that my ping improved slightly at the same time.

What - for the benefit of the uninitiated - does that explanation mean? smile

The VLAN is a sort of virtual interconnect between Openreach and your provider (or your provider's backhaul provider, e.g. BT Wholesale).

In practice, what they really mean is that they reprovisioned your service, and provisioned it correctly this time.

It means there was an issue with the BT Wholesale virtual path (SVLAN) at your exchange, you appear to have been moved onto a different SVLAN which has fixed the issue.

Not quite.

A customer VLAN (CVLAN) is what was tweaked here.

Multiple CVLANs can be placed inside a single SVLAN (or no SVLAN).

Incorrect profile = Usually VLAN (CVLAN)
Poor varying speeds = usually a busy (hot) SVLAN.

This was correctly communicated as a VLAN issue.

Fair enough, I stand corrected.

@candlerb, @Highland76, @j0hn83 - Read with interest. Many thanks.

I found the BT reply to my provider in the case notes, though I'm not sure whether it adds anything very significant:

Hi
We have investigated the circuit and identified that there was an issue with the VLAN. A migration order was placed and that completed during the early hours of this morning, tests show the circuit is up.
Please retest this with your user, thanks

But this 2+ week saga (with engineers coming repeatedly to my house and sitting all afternoon banging away at their laptops and phoning base - to no point, it seems, as it didn't need a site visit and was only resolved when my provider escalated to the Complex Fault Team!) was likely incorrect provisioning rather than an actual fault in exchange hardware/circuit?

Had a similar 2+ week issue getting an FTTP speed re-grade actioned (or not as it turned out) during lockdown Mk 1 (is that how we should refer to it now?).

The issue was with the BTW system. These sorts of issues on FTTP that relate to VLAN provisioning / speed regrades are effectively ‘soft’ change that doesn’t require engineers to physically visit your property as all the changes are in the exchange.

I understand your frustration but its the process the CPs have to follow. Usually, an Engineer visit is booked to check the equipment at the customer's premises in the first instance even though its obvious there's nothing wrong in the home. I went through a similar experience a few months ago: when i migrated from a 330/30 to 1000/115 service (both BT Wholesale based), the upload on the 1 Gig service was stuck at 30 Mbps. Had an Engineer come over to my home, checked everything was fine and then he got on the phone to Openreach or BT Wholesale (can't remember which), they rebuilt the circuit and 10 mins later it was fixed.

I personally feel like there is a culture of ‘blame’ .... everyone wants it to be someone else’s issue ...... if Joe Engineer is sent out it ‘looks’ like the CP has done something.. it seems not to bother anyone that in such instances there is sod all the engineer can do.
