Migration from NetVIEWplus to WCR (Wholesale
Customer Reporting)
WCR is the new reporting tool to replace the
Netview Plus system and will include 21CN product
measures. You will shortly receive more details
about this, including an invitation to attend a

any questions you may have. We look forward to
your attendance on the forthcoming Web Cast and
to speaking to you all. In the meantime, if you
have any questions you would like to ask
beforehand, please do not hesitate to contact us
by e-mailing the WCR Team at btw.wcr_at_bt.com

Partial private circuits update TDM trial of
the initial stages of the agreed 2Mbit/s and
above strategyBill du CannTDM industry

21CN Deployment Strategy Plan (DSP) product
overview updates

• BTW Partial Private Circuits (PPCs)
• Sub 2Mbit/s PPCs
• Sub-2Mbit/s TDM portfolio infrastructure
  strategy is being evaluated as part of a separate
  feasibility study.
• We are investigating two main options
• 1) Extending the life of the current 20C DPCN
  beyond the current stated closure date of 2014
• 2) 21CN delivered options requiring the use of a
  sub 2Mbit/s NTE in conjunction with a 2Mbit/s
  circuit.
• 2Mbit/s (and above)
• BT Wholesales strategy for 2Mbit/s (and above)
  Partial Private Circuits is to retain the
  majority of its existing 2Mbit/s (and above) 20C
  PPC products and incorporate 21CN components over
  time to replace obsolete 20C network components.
• PPC portfolio retains its existing framework
  i.e. Points of Handover (POH) and will continue
  to use native TDM (SDH) technology.
• Initial technical trial towards the end of BTs
  financial year 2009/10.

13
Trial description
VC4 phase 2 FOA (Internal BT) is planned to
complete 11/12. Network embargo from 14/12 /09
to 8/1/10 TDM demonstration is planned for Q4.
Dates to be finalised along with scope. The TDM
demonstration is being considered in two
parts 1. basic VC4 highway as below with testers
at each end 2. once 1 is proven, extend to CP
and route their circuits as below and test
performance
14
TDM trial details

• The current proposed trial area is in Scotland
  (route between Edinburgh and Inverness)
• A briefing has been issued asking CPs to register
  interest and to indicate the following
• Preferred geographic area (with reasons)
• Confirmation of existing services and access
  infrastructure
• Preferred circuit types to test (speed,
  resilience, etc)
• An update will be provided in due course
  however if you wish to participate please let us
  know

• - Cardiff, G, L, E, F, Bridgend, Cardiff B,
  Pontypridd
• Will complete the migration of up to 350K voice
  lines
• Will provide key learning following migration of
  a complete DLE in a night
• Switched-on communications will be issued
• Project plan being revised in line with customer
  input
• MSAN upgrades in Pathfinder area will take place
  prior to Pathfinder Volume POTS
• First Call Server upgrades have already been
  successfully completed in readiness
• Second Call Server software drop being planned

CMSAN upgrades required

• The upgrade schedule for the CMSANs is being
  developed
• There will be short voice line outages for end
  users 2 impacts
• Upgrades will be performed in the early hours of
  the morning to minimise the impact
• 25 of non-live sites will be upgraded before
  the first live site
• Nelson will be the first CMSAN to be upgraded,
  followed by one weeks stability period

Cause Timing Experience Scale
MSAN upgrade-first impact. Between midnight 6am (10 mins elapsed time) Between 3am-5am, 5 minutes incoming outgoing call outage for all customers simultaneously non-critical calls in progress will be cut off. No Star Services freeze Only one MSAN Site will be completed per night.
MSAN upgrade -second impact On the same night between 1 and 30 mins after MSAN upgrade- first impact 2 minutes incoming outgoing call outage for all customers in batches of 5 linecards, successively, until all linecards have been upgraded. Non-critical calls in progress as a linecard is upgraded will be cut off. No Star Services freeze Impacts all end users on an MSAN site, in batches (max 320 at a time)

Migrations after Pathfinder Volume POTS

• Voice line migrations will be done on an entire
  Digital Local Exchange (DLE) basis.
• The pace and order of these will be determined by
  continuous review of the condition and capability
  of the current voice network and the pattern of
  demand for new voice services.
• BT intends to start additional DLE migrations
  when the subsequent pilot Pathfinder phases
  involving Belfast, Thamesmead and Redditch have
  also been concluded.
• This ensure the comprehensive proving of
  migration techniques
• BT intends to provide a minimum of two years
  notice of DLE migration.
• This means that voice line migrations to 21CN
  (beyond the DLEs listed for the pilot phases)
  will now occur no earlier than October 2011.
• Migrations post Pathfinder Volume POTS will be
  available via the Datasets

19
Migrations after Pathfinder Volume POTS

• Candidate list objective
• To provide a view of probable customer migrations
  beyond Pathfinder Volume Pots.
• Enable you to identify future migrations and
  impact on customers
• Selection criteria
• The criteria by which the sites have been
  selected ..
• 20C obsolescence capacity performance
• Where DLE Interconnect migration has been
  completed or underway
• Maximise use of proven 21CN core network.
• Confirmation of dates
• At this stage, planned dates are not available.
• As we confirm our plans and determine dates these
  will be announced
• We maintain our commitment to provide a 2 year
  window for notification when customer migrations
  will take place at these candidate sites

these sites complete the Pathfinder proving
capability with dates yet to be confirmed, we
have included with Candidate list for
completeness.

ISDN

• ISDN Strategy
• BT is developing an ISDN like-for-like service
  to be deployed in line with the roll out of WLR
  services on 21CN
• Huawei ISDN equipment will be tested in Northern
  Ireland - the trial will involve migration of all
  voice products (POTS, ISDN2 and ISDN30) on one
  DLE (Belfast East Unit B
• Fujitsu ISDN equipment in the Pathfinder area in
  South Wales - the trial will involve the
  migration of ISDN services onto all nine DLEs in
  the Pathfinder area in South Wales that have
  already had their POTS services migrated
• Two BT own-use ISDN trials as well as initially
  preparing Swansea for CP testing
• CPs will be able to make use of the Swansea test
  facility from October 2009 and/or, if suitably
  located, one of the BT own-use sites for the
  voluntary trialling at an appropriate date
• Delivery plans are currently under review
