What is the Self Service Repair tool? The Self Service Repair tool has been introduced to improve the customer diagnostic journey by providing customer access to tests that were not directly available previously. It is available via the btwholesale.com portal, as well as the XML interface. The tool caters for both 20CN and 21CN assets, and places standalone tests together in a single place to make it easier for customers to access them. There is a limit on the number of tests that can be run per Communication Provider in a daily period and this is based on a percentage of the CP’s Working System Size (WSS). NB: KBD will automatically run a Port Flex and/or Port Reset when a fault is raised against specific KBD outcomes (see next slide). Functions available within the Self Service Repair tool: 

Kill Session: This function terminates the IP session between the (Broadband Remote Access Server) BRAS and the customer’s router/modem.



Port Flex: The virtual circuit details and parameters are removed (deactivated) and then automatically rebuilt (reactivated) on the same physical port and hardware. This function deactivates and reactivates the ASDL service by ceasing the configuration on the port of the MSAN or DSLAM and then configures the port within the same parameters (cTag/sTag on MSAN or ci/vpi on DSLAM). This process can be effective in soft repairing a line with an IP type issue, where no physical fault has been identified but a Port Flex may be effective in restarting services at an IP level.



Port Reset: On some MSANs this operation is at the physical port level to disable and re-enable the ADSL service at a hardware level. On others this operation will lead to a cease and reprovide of the customer service port configuration – similar to a Port Flex reset.



RRT Historic Data: This is RRT (Reactive Repair Tool) data that displays the RRT prognosis screen, options for a 14 or 28 day historic data view, graphs and colour coded ‘7 DAY VIEW’ screens. For full details on the RRT data options available refer to the Reactive Repair Tool Best Practice User Guide on BT wholesale. (See Documentation section).



DLM Setting: This allows the user to amend the DLM profile by changing the SNR margin up and/or downstream (depending on product), add or take off interleaving (depending on the interleave option selected by the CP when ordering the service), lock a profile against an asset, etc. A CBT package will be available in the Learning Academy to guide CP’s on the use of this new functionality.

Alternatively, go to btwholesale.com/register and follow the online instructions. You'll receive an email confirmation once your registration has completed successfully. To obtain access to eCo Plus, NewKBD and other applications, the Communication Provider must first set up a My Admin account on BT wholesale. This allows for an individual or multiple My Admin profiles to be set up as required. To apply for a My Admin profile complete the My Admin Application form which you can access by selecting the Administration tab, then the My Admin tab. Please send this completed form to [email protected] or via your Account Manager. The CUG ID details are mandatory as the application can't be processed without this detail. The lead-time for access to My Admin is 5 days.

Self Service Repair tool Access To obtain access to the Self Service repair tool:  





Select the My BT Wholesale > page and select the Faults & Diagnostics or Apps A-Z option, Locate the Self Service Repair tool option Click the Register for app > option and apply. Lead time is normally advised on the application screen. The applications will then be visible in the user’s My Apps menu when access is provided.

7

Entering the Security Pin Once you have access to the Self Service Repair tool in the My Apps menu click the Open app > button, enter your PIN number and click the READY button. If you already have access to Fault Diagnostics, this will be your existing PIN. The same PIN is used to access all diagnostic applications on the My Applications menu. If you've forgotten your PIN, click the Forgotten PIN link and answer the security question that you set up when first registering on BT wholesale. You will be sent a reminder of your PIN and when you next log in you will be prompted to change this.

8

Front screen From the front screen the user can view any previous test requests by clicking on the Actions link, or run a new test by selecting the Perform Actions link. There is also an option to view the My Jobs or My Company’s Jobs. My Jobs is the default for checking your own test results.

9

Perform Actions screen To run a new test select the Perform Actions link. From this screen the user can select one of the five functions. The default option is the DLM Setting function.

10

DLM Setting function The DLM Setting function allows the user to change the DLM profile of a 20C or 21C WBC asset. There are three new codes in NewKBD that indicate a DLM profile change may be required to stabilise a circuit and improve poor performance. These are NF37, NF38 and UD07. In addition to these codes, a circuit that is unstable or performing badly may benefit from a DLM profile change. This functionality also allows the user to ‘lock’ a profile against a circuit by selecting the DLM OFF option. NB: This will stop DLM automatically overriding the requested profile if any action is required to stabilise a line. To amend an assets profile enter the Service ID for the asset, select the required value(s) from the drop down options displayed and click the READY button.

The BACK TO HOME button returns to the front screen. RESET clears any data in the fields on this screen.

11

DLM Setting function – 20C and 21C WBC Parameters NB: The only options required for a 20C asset are: 1. Service Reference*: 2. Downstream SNR Margin: None (no change made to this parameter), 3dB, 6dB, 9dB, 12dB and 15dB. NB: If the user intends to apply a banded line rate to a 21C WBC product the user must always select 6dB in this field. Any other option will cause the profile request to be rejected.

3. Downstream Interleave Level: the options are None (no change made to this parameter), OFF or ON. (MEDIUM and HIGH are for 21C WBC assets only).

4. DLM Status: 

None (no change made to this parameter when new profile requested)



OFF means auto-DLM is disabled and the new profile cannot be overridden by auto-DLM.



ON means auto-DLM is functional and can change the DLM profile if the circuit requires further attention.

NB: The above options are also applicable to 20C and 21C WBC asset’s.

Interleaving options and timings: (ms = milliseconds) Interleaving Option Off

21C WBC Additional Parameters The additional 21C WBC options are displayed beneath the Below parameters only for 21CN ADSL (WBC End User Access) header. NB: The options below this line are for 21C WBC copper asset profile changes only. 5. Downstream Line Rate Kbits/s: 160-24384 is for the 24 Meg product only and 160-8128 is for the ADSL2+ up to 8 Meg product only. The additional options are banded profiles which when applied allow the asset to synch up and work between the selected parameters. (Only select 6dB downstream for a banded profile request). This can add stability to a service that is running at a high line rate and is unstable. NB: If selecting a banded profile for an up to 8 Meg ADSL2+ product the maximum band permissible is 3328-6656, as the next one up the list would exceed the 8 Meg limit on this service.

6. Upstream Line Rate Kbits/s: These options are specific to the product ordered. If the user selects an option that is not compatible with the product ordered then the profile request will be rejected. If uncertain of the product selecting None will mean the existing profile parameter will remain unchanged.

7. Upstream SNR Margin: The options are None (no change made to this parameter), 6dB and 9dB. 8. Upstream Interleave Level: The options are None (no change made to this parameter), OFF and ON.

When the required profile has been selected click on the READY button. An Acknowledgement screen will be displayed advising the change has been requested. To check the profile status and progress refer to the Work in Progress and Actions section.

If the user logs off before saving the test result it will be deleted. To hold the results for up to 48 hours from when the test was run the user needs to select the HOLD button. There is also an option to go BACK to the previous results screen, or to run the test again by selecting the RETEST button. After selecting the HOLD button the message changes to display the time left to hold the result. To undo the hold request the user needs to open the test result and select the UNHOLD option.

18

Port Flex, Port Reset and Session Kill Functions To run a Port Flex, Port Reset, or a Session Kill select the option required from the drop down menu displayed on the Perform Actions screen, enter the Service ID and click the READY button. The Acknowledgement screen, viewing and holding the test results is the same as described previously.

19

RRT Historic Data The RRT Historic Data functionality is a standalone RRT lookup that does not require a KBD test to be run before the RRT data can be viewed. The user can view 14 day or 28 day RRT data for a 20C or a 21C WBC asset via the RRT Historic Data function. The level of data in the RRT Historic Data functionality is higher than that via KBD and is equivalent to the view previously only visible to BT Wholesale agents. The user can also run a standalone RRT Lookup from the NewKBD test screen via the RRT Historic Data button for the selected 21C WBC copper asset. To run RRT Historic Data select the Perform Actions link, select RRT Historic Data from the drop down menu, enter the 20C or 21C Service ID and click on the READY button. An Acknowledgement screen will then be displayed. The DSL (Digital Subscriber Line) layer data is provided to the Reactive Repair Tool (RRT) database every 24 hours by DLM/BIP. It provides DSL layer information on the Upstream and Downstream line rate during this period, as well as SNR margins, Line Loss, Errors, Initialisations etc. Please note: If no RRT data is available in these fields then no graph or other detail will be available.

NB: RRT Historic Data is only available on 20C and 21C WBC assets and is not available on fibre assets (FFTC/FTTP).

20

RRT Historic Data: Actions & Results screen To view the RRT Historic Data select the Work in Progress link, then select Actions:

At the Results screen click on the Action ID reference for the required RRT Historic Data result:

22

RRT Historic Data: Default 14 Day Prognosis Screen After selecting the LAUNCH RRT option the default 14 day Prognosis screen is displayed. NB: For full details on the RRT data options available refer to the Reactive Repair Tool Best Practice User Guide on BT wholesale. (See Documentation page). There are several options for viewing RRT data from this screen: 

The default 14 day Prognosis screen provides a simplistic Prognosis statement, a description of how specific parameters are performing, min/avg/max values for each parameter; etc.



To view the 28 day Prognosis screen select the Further History link;



To display a 14 day graph select the View Graph link next to the relevant parameter. Similar to the KBD graphical view this will open a graph where up to two parameters can be displayed at the same time. All One Day views are now in 15 minute bins;



The Diagnose further with RRT.. button provides a grid view displaying a list of days, broken down into colour coded hourly blocks. A key to the colour codes is displayed on this screen also, as well as additional graph & detail options;



To display the BRAT graph select the BRAT (Brandenburg Rapid Analysis Tool)-in Trial link;

23

RRT Historic Data: Further History (28 Day View) Prognosis screen To access the 28 day Prognosis screen click on the Further History link. The Prognosis statement now indicates the 28 day period in the ‘from’ and ‘to’ statement. Clicking on any of the View Graph links will display the 28 day view for the selected parameter and allow the user to select other parameters; up to a maximum of two parameters on the graph at the same time.

24

RRT Historic Data: 28 Day View Graph screen For 21C WBC assets there are 14 parameters displayed in the RRT Historic Data 14, 28 and single day view. (For 20C assets there are 10 parameters displayed in the 14, 28 and single day view). There are also Profile Change (*) and Intrusive Test (~) markers. When data is available these will be visible against the relevant date on the graph. In this example the Downstream Actual Line Rate and Downstream MTBE(ES) parameters are selected. The parameters can be selected and deselected as required to display any two parameters at the same time. To view the one day graph, enter the required date in the View 1 day 24 hour view field. The date must be entered in the same format it appears on the graph (E.g. 01-Jan-2015) and click on the Display Graph button.

25

RRT Historic Data: One Day View Graph screen To view the one day graph enter the required date in the View 1 day 24 hour view field of the 14 or 28 graph view. The date must be entered in the same format it appears on the graph (E.g. 01-Jan-2015) and then click on the Display Graph button. The single day graph view will then be displayed (see below). The RRT Historic Data 1 day view is displayed in 15 minute bins. For the RRT Historic Data view the MTBE parameters are displayed on the single day view. So the same amount of parameters as the 14 and 28 day views are displayed in the daily view. The day can be moved forward or back within the 14 day period by selecting the < or > buttons. To return to the 14 or 28 day view, select the ^ button. To close the graph view click on the Close button.

26

RRT Historic Data: Diagnose further with RRT.. The Diagnose further with RRT.. button provides a list of days broken down into colour coded hourly blocks. A key to the colour codes is displayed on this screen also, plus additional graph and other detail options. To access this screen click on the Diagnose further with RRT.. in the 14 or 28 day Prognosis screens. There are several options on this default 7 DAY VIEW grid screen:         

There is a Key denoting what the different colours indicate in the hourly blocks. Also, if the user hovers over an hourly block a description is displayed. The colour coded hourly blocks will also contain a > symbol if there has been a profile change and hovering over that block will display the DLM profile that was applied. To display a 14 DAY VIEW click on the Expand button; Report Summary takes the user back to the previous Prognosis screen; The > is enabled when the is enabled when the < option is selected. Clicking on any hour in the Hour Of Day field displays a LAYER 3 VIEW – 3 hr view across 14 day period screen where the user can display a 3 hour view over 14 day in a graphical and tabular format. Clicking on any of the day links (e.g. 13-Jan) displays a LAYER 3 VIEW – 4 hr view over 3 days screen where the user can also display a 3 day graph view and access 3 days view of hourly detail in a table. The Feedback link is not functional. Please do not use this option.
