Backstory:
So I been dealing with a developing fault on an ADSL1 Plusnet ( 20CN / Market1 exchange hence OpenReach ) for the last few weeks and finally got PN to the point of recognising the increasing local loop errors that I been monitoring from Broadcom chipset CPE for weeks.

Since I already spent the effort to understand this stuff, I thought I would contribute a 'breadcrumb trail' that may be of some aid to other forum searchers in future.

Summary
Customer advsing seeing more drops
Brat showing fec errors and Severe REIN
SFI required

Searching the forums for 'BRAT' only found 4 references, each of which is more of a 'mentioning in passing' than an explanation.

So naturally I searched a bit further to see what I could find.

Customer Introduction

https://www.btwholesale.com/assets/documents/knowledge_based_diagnostics/BRAT_Introduction_for_CP's_v2.0.pdf

Searching 'SFI required' found these two snippets which will be old news to those of you for whom $DAYJOB is CP / xDSL related, but news to me, since I only am compelled to deal with BT/OR whenever I have issues to resolve. 

Service Harmonisation
'We’ve simplified our service maintenance structure – from nine options down
to just four options – and renamed them Maintenance Options  1 to 4. We’ve
also introduced the four new enhanced service offerings you asked for – Missed
appointments, flexible appointments, Expedite Repair and Special Fault
Investigation 2 (SFI2).

Service Maintenance Levels
There are four Service Maintenance Levels – Missed Appointments, Flexible
Appointments, Expedite Repair and Special Fault Investigation 2 (SFI2).

I also found two other BTWholesale public documents that others may find interesting.

That's a URL to a .pdf I don't have to post, 'cause they already did.

Thank you for sharing.   I'm not even going to attempt to read those tonight, but shall bookmark for later

[burakkucat]

Thank you. 

I, too, have added certain documents to my electronic library. I eventually created separate sections under a "BT Group" heading --

• BT_Cables
• CPEs
• ISDN2e
• Kilostream
• Openreach
• SINs
• Wholesale

I just need to remember to read those new additions.
