Introduction
This best practice guide, provides Communications Providers (CPs) key information,
on how to efficiently manage Left In Jumpers (LIJs) and understand the LIJ warnings,
to help reduce avoidable charges during the ordering journey and reduce early life
failures by needless network intervention.
This guide also touches on the R2400 “Dummy” functionality, which gives CPs the
maximum opportunity to reduce potential LIJ charges (current pricing can be found on
the Openreach portal under LLU pricing)
The guide is aimed at CPs business analysts, IT designers, product and process
specialists.
When followed, this guide should help to reduce the avoidable LIJ charging.
This presentation aims to both raise awareness and give guidance on best practice
around inventory management and order processes for Flexi Cease, when allocating
tie pairs for their end user orders.
The scope of this document provides coverage of the provision process and includes
best practice for the Local Loop Unbundling (LLU) Metallic Path Facility (MPF) and
Shared Metallic Path Facility (SMPF) Product(s) and is correct as of EMP R2400.
Slide 5
What is Flexi Cease
Flexi Cease is a term applied to the Local Loop Unbundled (LLU) products (MPF) and
(SMPF). Although the services are ceased there is no actual removal of Main Distribution
Frame (MDF) jumpering, the line at this stage is in a status of ‘STOPPED’ and the tie
pairs are in the state of Left in Jumpers (LIJs)
A CP could submit a jumper removal order, after the cease is complete which would
remove the MDF jumpers completely, the tie pairs would no longer be LIJ.

Slide 8
Information
Terminology of LIJs and their locations
Left In Jumper (LIJs): Means that, on completion of the cease request, the jumpers on the MDF
will not be removed. The following terms will help you understand the terminologies associated
with LIJs:
• Spare Tie Pair: Means a tie pair that is spare and does not have LIJs
• LIJs at Target : Means that the tie pairs associated with the address where the new service
has been requested are in a LIJ state and owned by yourself. If this tie pair is not reused at its
current location on an order response code 1884 will be sent.
• LIJs at Donor : Means that the tie pairs you supply for the provision address are currently in a
LIJ state, routed to a different address. If this tie pair is used on an order to a different location
to the current one response code 1885 will be sent.
• LIJs at Donor and Target : Means that the tie pairs you supply are in a LIJ state to a different
address from the target address (LIJ at donor) and at the same time the tie pairs associated
with the address where the new service has been requested are in a LIJ state (LIJ at target). If
this tie pair is used on a order response code 1886 will be sent.
• Dummy (R2400): Used when you are uncertain of network against address routing if LIJs at
target, Openreach will confirm in KCI 1.6 if target ties exist and belong to you.

Slide 9
LIJ Response Code And Warnings
Information
These are the existing response codes that serve as a final warning to CPs that
they may incur charges for removal of LIJ ties.
Response Code
Response to CP text
1884
The target circuit already has LIJ tie pairs that belong to you. If this order continues, then
you will incur LIJ removal-Target charges to remove the LIJ ties.
1885
The donor circuit already has LIJ tie pairs that belong to you. If this order continues, then
you will incur LIJ removal-Donor charges to remove the LIJ ties.
1886
Both target and donor circuits already have LIJ tie pairs that belong to you. If this order
continues, then you will incur LIJ removal- Target and Donor charges to remove the LIJ
ties.
Response code XML templates can be found within the XML specification
documents on the Openreach Portal
Slide 10
Information
R2400 “DUMMY” Functionality
R2400 has delivered an enhanced ordering journey, that enables CPs to use
“DUMMY” within the order XML, resulting in Openreach completing the exchange
and LIJ validations at “Routing Completed” KCI 1.6 stage. When a CP provides tie
pairs on an order, it makes sense to return LIJ warnings after the routing step has
been performed.This functionality gives the CPs the opportunity to maximise their
re-use of their LIJs and minimise their exposure to LIJ charges.
On Release R2400 deployment (MPF/SMPF)
• MPF and SMPF KCIs will contain the exchange (MDFSiteId) tag
• New KCI 1.6 for Dummy tie pair orders
• New LineStatus of “Routing Completed” for KCI 1.6
• Amend tie pairs on Dummy orders to be placed after KCI 1.6
• New Response Code 517 for KCI 1.6
• LIJ warning Response Codes (1884/1885/1886) move from KCI 1 to KCI 2

Best Practice
Process for Avoiding LIJ Charges
The swim-lane process on the following slides outlines the best practice process for
managing all ordering scenarios with LIJs (without using R2400 functionality).
Slide 12
Best Practice
For MPF
Openreach FRAMES
Communications Provider
EMP
Runs Address Match & MLPA
Return NAD key & any stopped lines
N/A
Runs eMLC (on access line ID) to identify
Target LIJs
Return eMLC response with or without
Target LIJs
N/A
If eMLC has returned Target LIJs, CP
should use the same in the order. Failure
to use returned LIJs will create charges
No Target jumper recovery charges
applied
N/A
If there are no target LIJs, then run Tie
Pair Checker Dialogue Service against the
tie pairs you intend to use in your order
Return Tie Pair Checker response
indicating whether the ties in question are
Donor LIJs or not
N/A
If Tie Pair Checker indicates Donor LIJs,
then charges will be raised if these tie
pairs are used in CP order
N/A
N/A
If CP does not wish to incur LIJ charges
please ensure you re-use Target LIJs or
supply spare Donor LIJs
No Donor or Target jumper recovery
charges applied
N/A
Based on eMLC and Tie Pair Checker
response, CP is now ready to place the
order
KCI Messages relayed to CP in correct
sequence. Subject to correct usage of tie
pairs, LIJ recovery charges will not be
applied
Openreach engineer will jumper the tie
pairs (as indicated on the order by the CP)
and completes the FRAMES activity

Slide 14
Best Practice
Best Practice for Inventory Management
Below is a set of recommendations for our CPs to effectively manage their own
inventory.
Recommendation
Manage tie pair inventory by recording jumpers in use, spare, or left in by using KCI 3
messages from the orders associated with the jumpers.
Use Tie Pair Reconciliation Report (TPRR) to obtain Tie Pair details that you own. This is
available via the Openreach Portal.
Tie Pair Checker Dialogue Services and eMLC are also at hand to obtain the tie pair status
and also MLPA to look at stopped lines for potential re-use.
Check if you have any quarantine periods in place for reuse of your LIJs, consider any
removal benefit.

Tie Pair Reconciliation Report is made up of the following headers:
CP_ID: This is your Duns ID
MPF_SITE_ID: This is the exchange ID of the exchange the Tie Cable and Tie Pair terminate within
TIE_CABLE_ID: This is the Tie Cable ID that the Tie Pair terminates on
TIE_PAIR_NUMBER: This is the Tie Pair number
SERVICE _ID: This is your Service ID that is related to your active/live services e.g. there should be one record for an MPF service and two for an SMPF service.
LIJ_STATUS: This shows if the Tie Pair is in a left in status and will be set to either Y/N
TIE_PAIR_STATUS: This field provides the Tie Pair Status and can be set to either S=spare N=not spare F=faulty
COMMENTS: The comments provide basic information on the Tie Pair
