KBD … feedback from Customers
• Current diagnostic time averages 6 mins.
Takes Too Long!
No Non-Interactive
Option
Inefficient
No Non-Intrusive
Option
• Customers want to hit a button and get a diagnostic result. They don’t want
to answer many questions.
• Some tests currently performed serially.
• Some tests are executed when not necessary.
• There is no option to do non-intrusive testing on a line first. Hence Customer
needs to spend time calling end-users on alternate numbers when testing
the line.
Too Many Outcome
Codes
• Hundreds of KBD outcome codes.
• Simplified/rationalised/tightened up.
Diagnostic Accuracy
• Must be above 90%
• Consistent fault baseline.
From CustomerFeedback
ServicEdge Review 14/03/12
THE PROPOSAL
Existing KBD
Simplified KBD
A number of structured questions
adding to test execution time
Non-interactive model during test
execution. Fewer questions asked
upfront .
Large number of outcome codes (220)
Lesser number of outcome codes (90)
across WBC Copper, FTTC and FTTP
Large number of workflows (38)
Reduced number of workflows (13)
Outcome codes follow Test specific
notation
Outcome codes categorized in
domains like Home, Network, Access,
No Fault, Further Diagnostics which
aligns outcome codes with localized
domains
Complex and Heavy
Light weight and simpler
Copper Line Test called in 29 places in Copper Line Test called in only 3

1. Reduction in time, information available to Customers
2. Reducing the need for Customer contacts into BTW
1. Customer control of EU DSL profile to either optimise performance or stabilise service in a fault scenario.
2. Accommodates Customer own CPE/chipset given that the product is 'wires-only'
1. Allows Customers to throttle downstream speed to align with the Sync Speed of the EUs router.
2. Reduce First or Second cycle faults by managing throttling without having to report a fault into BTW
1. Customers will have the capability to test the network and confirm whether the End User is configured correctly where an IP connection issue
is being experienced.
2. Allow Customers to confirm the DSL, ATM, PPP and IP layers are functional between these points including QoS tests.
1. Discussion required with Supplier - Openreach
2. SoR
1. TRDB will assist Customers in normal first cycle or repeat type faults.
2. The database will provide records of test results to assist in repeat type faults
1. Customers able to do meaningful and accurate diagnostics for EU Home and Access domain issues.
2. RRT data over 28days with near real time data will provide greater confidence to progress CCSFI or Boost orders for Openreach
investigation
3. Offers Customers greater control and confidence to manage Home related problems with EUs
1. Customers can view data longer then 24Hrs (up to 48Hrs)
2. Including whether any IP (Internet Protocol) session connectivity has occurred or ‘Worked’ (not currently connected) or ‘Working’ and how
long that working session has been established.
3. The IP Connectivity Log data, however will be 10-15 minutes behind so is close to real time.
4. Show any attempts to connect, short sessions (potential intermittent IP connection issue) etc.
1. Reduction in cycle time – queried time to resolve. Following TOR how quickly is this passed back to CP when successful?
Provide Customers with greater visibility of BTW's EMU notifications
1. Quick and easy standalone check to confirm any account, network or connectivity issues that may be impacting the ADSL Broadband or
FTTx Broadband service.
2. Substitute for the standalone IP and Status Checks
3. Faster and more accurate identification of connectivity issues.
4. Optimises test performance by using logic to determine what checks are required and will run tests in parallel where applicable.

Real-Time QoS – Summary of Features
Benefits
Features
Network Performance
Availability
Key Considerations
• Allows important time/quality critical traffic to be prioritised
• Minimises packet loss, jitter and delay
• Enables customers to provide assurances against applications like VoIP and Video
Conferencing
• Utilises the industry standard ‘Expedited Forwarding’ (EF) DSCP marking
• ‘Traffic is strictly prioritised in the downstream direction within the WBC network
• WBC network congestion is heavily asymmetric in the SVLANs, thus upstream is not
congested and does not require strict prioritisation
• BT Wholesale monitor network performance using independent third party robots
(Epitiro). Packet Loss no greater than 0.1%
• Round Trip Delay (latency) no greater than 30milliseconds
• Jitter no greater than 15milliseconds
• Available on WBC ADSL2+, FTTC and FTTP
• £3.50 for 1Mb per end (at launch) user plus £53.55 per Mb contracted bandwidth
(WBMC Shared)
• Recommended ADSL Annex M is consumed to optimise upstream bandwidth
• Recommend Super Stable or Custom Dynamic Line Management profiles are used
• CPs need to ensure their End User’s CPE supports Real Time prioritisation in both
upstream and downstream directions.
Dynamic Line Management (DLM)
ADSL1
ADSL2+
Benefits
Upstream problems managed
through downstream DLM
changes
Separate upstream and
downstream DLM changes
No loss in downstream
speeds for upstream problems
Limited set of profiles
available
Increased set of profiles both
fully rate adaptive and banded
Allows DLM to better manage
more severe line issues
Limited level of interleaving
available
Multiple interleaving levels
and much higher protection
Improved impulse noise
performance
Interleaving cannot be
removed by DLM when noise
improves
Where “Auto” is selected &
interleaving is applied, can be
auto-removed if noise
improves
Improved rates when
interleaving not required
Limited control over DLM
More custom control over
DLM
Allows customer to tune DLM
for specific service
Slow to react to problems and
improvement
(2 days and 14 days)
Faster to react to problems
and improvements
(2 days)
More reactive to changes of
line conditions
ServicEdge Review 14/03/12
Annex M– Summary of Features
• Optional feature of standard WBC end user lines
• Permits higher upstream rates
Benefits
• Extends theoritical upstream speed to 2.5Mb
• 1Mb on Annex A
Features
•
Network Performance
Availability
Key Considerations
This is achieved by allocating a small part of the bandwidth that would normally be
used for the downstream channel to the upstream
• Results in a slight decrease in downstream rate
• Available on WBC ADSL2
• £7 per end user per month
• Can be used in conjunction with Real Time QoS
• Annex M can only be used on loops which are 38dB or shorter in length
• Due to regulatory restrictions
Back-Up
How RTQoS Works
WBC Network Prioritisation:
1.
Real-Time QoS marked traffic (‘Expedite Forwarding’ – Industry standard DSCP mark EF) arriving
from the CP’s network in the downstream direction will take priority at the Aggregation Point over all
other traffic as it flows to the BRAS.
2.
Traffic marked as real-time will have first access to the SVLAN during the queuing process, with the
BRAS ensuring that all RTQoS queues are emptied before the best-efforts class is served.
3.
Each SVLAN will have a maximum RTQoS partition. This partition will ensure that bandwidth is
reserved for real-time traffic when required.
4.
Traffic that exceeds RTQoS Contracted Bandwidth at the AP will be treated as RTQoS Burst
Bandwidth. Customers are responsible for determining the level of traffic being prioritised and
appropriate capacity.
5.
Traffic that exceeds the End User Contracted Bandwidth will be discarded.
RTQoS – Host Link/AP Bandwidth Utilisation Benefits
Network without RTQoS
• CPs wanting to ensure all of their End Users
critical data is transmitted during the busiest
periods would have to purchase significantly
more bandwidth in-order to provide
generous planning rules against peak
utilisations.
Network with RTQoS enabled
• CPs can ensure that during the busiest
periods their end users critical data is
prioritised and transmitted without delay or
loss.
• CPs would not need to provide generous
planning rules to protect business data, thus
reducing the overall best efforts bandwidth
required.

Basic Overview
DLM is an active line management process that monitors performance
and automatically re-configures a line when needed
Detailed line performance information is captured on a daily basis
DLM categorises each line daily based on this information
Primarily uses errors and re-trains in this categorisation
Limits (thresholds) are set on these metrics to determine good and bad
performance
A line is re-profiled if needed
Upstream and downstream are categorised and re-profiled
independently
DLM learns from the changes it has made based on a historical view of
how the line has performed

Broadband retirements – Migrations Surgery
How to migrate from 20C to 21C
30
Migrations Context
-
-
BT Wholesale is looking to close down the 20C network
- Datastream will be retired
- IPStream will be retired in the WBC footprint
WBC is the suggested replacement product for most 20C users
Aside from the retirement of the 20C products, there are other good reasons
to move users to WBC
- WBC is faster than the 20C products
- WBC is cheaper than the equivalent 20C product
-
We are looking at ways to improve the migration journey
31
Migrations to WBC
Two processes available:
- Singleton process:
- £11 per order
- 5 day lead time on orders
- Customer determines the exact date of migration
-
32
Bulk migration process
- Free
- 12 day lead time on orders
- Requires forecast into BT Wholesale 8-12 weeks before migrations start
- Openreach determines the date on which the migration at a given
exchange will take place
- Only offered where BT Wholesales demand for migrations at an exchange

Ensures CP forecasts fit within Openreach resource
constraints
Recognises minimum 10 requirement and coordinates across multiple CP forecasts to achieve
33
-
Simplifies bulk migration process further for
customers
Further process enhancements
Left-in Jumper top-up process
- Currently being trialled with Openreach for where BT Wholesale forecast 10 or more
migrations but <10 orders are placed
- Proposal is to top-up the migration orders with orders to remove Left-in jumpers
- Prevents the need to cancel the migration orders
- If trial successful may look to extend to allow mop-up of end users prior to IPStream
retirement at a specific exchange
Openreach project services
- Engagement with Openreach project services teams to support more bespoke or
tailored migration options (e.g. engineer rings CP before then rings CP after migration)
Out of hours migrations
- Investigating whether a short term solution can be put in place to enable migrations out
of hours
6 month notification countdown
- BTW seeking to produce a notification to send to customers of all active end users on
exchanges due to be retired 6 months before the exchange retirement date

Version 2 – 14/02/2012
But some tough challenges ahead as a result of the weather…
Latest position:
•
Over a ten week period up to mid-September, fault intake to Openreach was 23% above typical
industry levels, placing an additional strain on overall recovery
•
Further bad weather and flooding led to the fault repair stack increasing to 25,500 as at 27th
September vs. c16,000 the weekend prior (within OR’s standard operating range).
•
As a result, lead times for repair and provision could increase with additional risks to missed
appointments – the effect of this will be additional contacts and escalations and this may continue
through into December.
Actions taken in Openreach to improve the situation (expected to impact in Q3):
•
Resource reallocation: Over 600 people in training to be deployed Q3
•
Recruiting permanent Resource: recruited 400 with another 440 joining shortly
•
Recruiting temporary resource: recruited 400 with a further 600 joining shortly
•
Improved productivity: Reduced all non-essential training to maximise effectiveness
•
Enacted contractual overtime
•
Expected recovery within Q3
•
Additional detailed communications will continue to be issued as MBORC or general service
updates from Openreach.
37
There are several ways that we can help to improve things…
BT Wholesale are helping by focussing on:
• Dwell time (how long jobs sit in our queues) & turnaround times are as short as they have ever
been to help with on time repair and to jeopardy manage against provision failure – this focus
will be maintained throughout Q3
• Deploying software upgrades across our exchanges to improve line card performance and
deliver significant reduction in faults
• Improved accuracy of the KBD tool (we hit 90% in August)
• Minimising need to contact Openreach and book engineering visits (unless needed).
How you can help:
• Always check the fault and order tracker for updates before contacting BT Wholesale and only
where it has passed its committed date
• Ensure there is an open fault prior to making contact
• Where a fault fails a retest it will automatically route through to Wholesale diagnostic teams so
there is no need to chat in
• Complete a satisfaction survey on e-chats so we know where to improve
• Encourage agents to be as direct and specific on the question that needs to be answered via
eChat
• Always follow the escalations process as per the CSP
• Let us know your ideas for how we could work smarter at busier times
