1003 Changes since June 6
  • Slide 22 - Provisioning warning response code
    meaning corrected
  • Slide 23 CP actions in response to new messages
    corrected
  • Slide 34 Jumper recovery warning response code
    meaning clarified

5
Introduction
  • This information is compiled with the view to
    helping CPs assess the impact of R900 Flexi Cease
    on their systems even if they are not upgrading
    their XML
  • It does not cover changes to business rules or
    commercial/product information
  • This information is based only on the incomplete
    solution designs for R900 Flexi Cease that are
    currently available.
  • Further functional and technical upgrade
    documentation will be provided prior to R900
    release to meet with the agreed industry
    milestones
  • This information is provided in good faith and
    whilst every effort is made to ensure the
    information is correct at the time of compilation
    Openreach does not accept any liability for any
    errors or omissions in the information

6
Background To Flexi Cease
  • Flexi Cease is about leaving jumpers in when an
    end user ceases a service
  • It means Openreach does not need to visit the
    exchange to remove jumpers
  • If a new end user takes over the service with the
    same CP, Openreach does not need to visit the
    exchange so long as the CP re-uses the Left In
    Jumpers (LIJs)
  • This saving to Openreach has already been passed
    on to CPs in the form of reduced cease charges
  • Where a CP forces a change in its jumpers,
    Openreach will now charge for this work.

7
Clarification on Left in Jumpers and Potential
Charging
  • To help clarify what Openreach will and will not
    charge for we have 6 examples
  • LIJ Re-use no additional charges
  • LIJ at Target additional charges
  • LIJ at Donor additional charges
  • LIJ at Target and Donor additional charges
  • LIJ for another CP no additional charges
  • LIJ for another CP and LIJ at Donor additional
    charges

Dialogue Services and Reports

15
1003 Enhanced Dialogue Services to Support
Flexible Cease
  • Scope MPF and SMPF
  • As long as CP is on Release 800 for Dialogue
    Services it can avoid the new jumper recovery
    charges that may be incurred during MPF and SMPF
    fulfilment.
  • There are 3 improvements
  • Enhanced MLC (Manage Line Characteristics)
    Dialogue Service Returns tie pair details if
    circuit is LIJ (Left In Jumper) for MPF as well
    as SMPF
  • Allows CP to check if it already has LIJs
  • MLC DS is available via B2B, the portal and the
    web services gateway.
  • Classification Partial CP only needs to be on
    R800, since all the schema changes were delivered
    then and there are no new response codes.

16
1003 Enhanced Dialogue Services to Support
Flexible Cease
  • Tie Pair Checker Dialogue Service
  • Returns Tie Pair Status (Spare, Not Spare,
    Faulty, Left In Jumper (Y/N)) for MPF as well as
    SMPF
  • This will enable CP to check if possible a tie
    pair is spare for use in an order where there are
    no LIJs
  • Tie Pair Checker DS is available via B2B, the
    portal and the web services gateway.
  • Classification Partial CP only needs to be on
    R800, since all the schema changes were delivered
    then and there are no new response codes.

17
1003 Enhanced Dialogue Services to Support
Flexible Cease
  • Enhanced Tie Pair Utilisation Report
  • Returns LIJ (Left in Jumper) status (Y/N) for MPF
    as well as SMPF
  • This information is included whatever version of
    schemas CP is on.
  • Report data may be up to a week old
  • Report is only available for download via the
    portal.
  • Note A change is being looked at to allow CP to
    specify exchange it wants report for, but
    currently CP gets all its tie pair data in one,
    potentially very large, report.
  • Classification Full Whatever schema version
    CP is on, report will include LIJ status.

18
Fulfilment

19
LLU R900 Flexi Cease Fulfilment Impact Summary
20
1003 Flexi Cease Dependencies
  • Completion of SMPF Tactical Asset Conversion
  • Tempo 542 was delivered in R800 and is currently
    due to complete conversion of SMPF assets in time
    for R900.

21
1003 Flexi Cease Provisioning
  • Scope MPF and SMPF Add and Amend Orders
  • Before a CP places a new MPF or SMPF order, it
    should use the MLC and TPC Dialogue Services to
    identify latest Left In Jumper (LIJ) status to
    avoid needless jumper removal charges. If not it
    may receive new warning messages, which, if not
    acted upon, will result in jumper recovery
    charges being applied.
  • If the CP forces the removal of their own LIJ
    ties at target and/or donor, a new warning will
    be sent in KCI1, to notify of the extra charge.
  • For SIM provide CP will only be charged for
    donor LIJ recovery with notification at KCI1.5
  • If the CP progress an order where it is forcing
    the removal of its own LIJ Ties, then the CP will
    be charged extra.
  • If charges are invoked, the CP will get tie
    details as part of bill.
  • Classification Full Response Codes will be
    sent regardless of which release the CP is on.

22
1003 Flexi Cease Provisioning
  • New Warning Response Codes

23
1003 Flexi Cease Provisioning
  • CP Action in response to new warning message
  • Where LIJ ties at target CP can only cancel order
    and resubmit with correct target LIJ tie pair or
    pay LIJ removal charges. (Tie Pair Amendment not
    allowed where tie pair specified in order is
    spare or LIJ in another circuit)
  • Where CP specified tie pair in order that is LIJ
    in another circuit and it has no LIJ at target,
    again it can only cancel order and resubmit with
    a spare tie pair or pay LIJ removal charges.

24
1003 Flexi Cease Provisioning
  • Recommend Upgrade to R900
  • But as a Minimum Suggest.
  • Use Release 800 versions of MLC and TPS dialogue
    services prior to placing any provide order
    (Portal will automatically show latest versions
    of dialogue services)
  • Just in case, at least make sure your systems can
    cope with unrecognised response codes.
  • Amend your systems to recognise new codes 1884,
    1885 and 1886
  • Review Tempo 735 (Product Based Versioning) to
    see how it may help you

25
1003 Flexi Cease Jumper Recovery
  • Scope MPF and SMPF Left in Jumper (LIJ)
    processing
  • Description
  • There will times when either Openreach or the
    CP needs to recover Left In Jumpers due to
    operational issues or equipment renewal /
    upgrade.
  • MPF and SMPF Jumper Recovery orders can be
    raised by Openreach or the owning CP.
  • Receipt of KCI3 for a jumper recovery order
    implies the tie pair(s) is (are) now spare.
  • Classification Upgrade - New XML and Response
    Codes

26
1003 Flexi Cease Jumper Recovery
  • Openreach initiated Jumper Recovery (Unforced)
  • Openreach will recover jumpers with a status of
    LIJ when the Main Distribution Frame (MDF) or
    Handover Distribution Frame (HDF) is under stress
  • The CP will not be charged
  • CP will receive KCIs advising it of progress, if
    it has upgraded to at least R900
  • Openreach raised jumper recovery orders can be
    recognised by Managed Provide in OrderSubType
    in the KCI XML for Left in Jumper Recovery
  • CP will not be able to Cancel or Amend Openreach
    raised Jumper Recovery orders
  • If CP believes there is a live service on the
    jumper, it will need to contact the SMC directly.

27
1003 Flexi Cease Jumper Recovery
  • Forced Jumper Recovery
  • There will be times Openreach is forced to
    recover jumpers
  • CP forces recovery of its own target jumpers on a
    new provide
  • SMPF CP induced narrowband fault on flexi ceased
    SMPF circuit still supporting a narrowband
    service
  • CP provision forces jumper recovery of another
    CPs jumpers at target.
  • In all these cases Openreach will send affected
    CP jumper recovery KCIs so CP can keep its
    inventory up to date
  • Other than case 3 above, KCI will also have a new
    warning response code notifying CP of additional
    charges.

28
1003 Flexi Cease Jumper Recovery
  • CP initiated Jumper Recovery
  • CP can raise Jumper Recovery Orders for its own
    LIJs once it has upgraded to R900
  • CP will receive KCIs advising it of progress
  • CP raised jumper recovery orders can be
    recognised by New Provide in OrderSubType in
    the KCI XML for Left in Jumper Recovery
  • CP can Amend the CRD on Jumper Recovery orders it
    has raised
  • CP can Cancel Jumper Recovery orders it has
    raised
  • The CP will be charged for its own orders and
    amendments
  • Charge details will include Tie details and
    Service ID

29
1003 Flexi Cease Jumper Recovery
  • Singleton and Bulk Jumper Recovery Orders
  • Two types of Jumper Recovery order bulk and
    singleton
  • Singleton will have three day lead time
  • Bulk (new Bulk tag in XML set to Y) will have
    10 day lead time. No decision yet on charges.
  • Bulk to be used where a number of jumper
    recoveries at an exchange need to be carried out.

Assurance

36
LLU R900 Flexi Cease Assurance Impact Summary
37
1003 Flexi Cease Related One Off Fault Charges
Scope SMPF charges for fault investigation into
a loss of narrowband service and resulting jumper
recovery resulting Where an SMPF LLU circuit has
Left In Jumpers (LIJs) and the owning CPs
equipment is removed, changed or develops a
condition that results in a loss of narrowband
service to an end user, an Openreach engineer
will investigate the matter and remove the LLU
CPs jumpers if necessary. In this instance
charges will be raised against the LLU CP for the
investigation by Openreach and the recovery of
the CPs jumpers. The jumper recovery charges
will also show details of the tie pair on the
bill. Investigation charges will show details of
the service on the bill. Classification Full
CP will be charged whatever release they are on.
It is planned to switch charging on at the same
time the Flexi Cease Fulfilment functionality is
switched on. CP will only receive unsolicited
KCIs for the jumper recovery if it is on at least
R900 though.
