Thanks guys for finding the additional info, a quick scan suggests that the MA5603T were using VDMF lincards and the MA5616 was using VDSH linecards. Yet BS's post implies VCMM line cards already in the network, so Im a bit confused about a swap out and which way. Have I misunderstood something or are they saying that all cards will now be VCMMs.
Whatever way it appears that they have found an issue that causes significant reduction in upstream rates and loss of syncs on long lines.
---------------------
BTW... That document also references EMP2750 which looks like the ISPs may be able to get better monitoring tools and diagnostics. It would be nice if they would have added the facility for the ISP to reset the DLM in there too, but sadly not. Anyhows......
It seems to imply EMP(R)2750 due for delivery 24th Jan 2015 and references back to the
Industry Forums secure login pages for ISPs, that Andy has been harping on about recently.
I did find a
public document though
GEA -FTTC Brandenburg NGA
Brandenburg NGA is an enhancement to the NGA Test & Diagnostic systems to improve the current method of determining if a GEA - FTTC circuit is experiencing performance problems and if that issue is due to a network or home environment problem.
This will be achieved through advanced diagnosis of network data to improve the location and diagnosis of faults causing poor SFBB performance and making additional test result information available to CPs .
Improvements will be made to the way of determining;
a) The cause of a drop in speed on a circuit.
b) The location and impact of interference problems.
CPs will have more information about the performance of their customer’s circuit which will enable their advisors to have a more valuable and insightful conversation with them about their problem, improved pre-qualification of any fault conditions and undertake better decision making regarding choosing the appropriate T2R products from Openreach.
In order to fully benefit from these changes CPs will need to consume the new information sent by Dialogue Services when a test result is returned.
