ECO PLUS WBC (FTTX) FAULT REPORTING TRAINING GUIDE

The WBC ADSL2+ 8Mbps EUA Transit product was introduced to enableCommunication Providers (CPs) to have a means to check whether it was likely that anend user‟s line would be able to consistently achieve higher level speeds before the CPcommitted to purchasing the ADSL 2+ (up to 24 Mbit/s) WBC EUA option i.e. the8MbpsTransit option is a transition product for the 24Mbps product. The followingprocess applies to such variant:The CP will order the 8MbpsTransit option for the applicable End User Access.The End User Access profile will be set at8Mbpsdownstream speed (as statedabove, even though the MSAN can sync up to 24Mbit/s, the speed is capped to8Mbpson the BRAS).Post stabilization of the applicable End User Access, the CP will be able to seethe actual speed which can be achieved on that lineIf higher speeds can be achieved on the line, the CP can go back to the end userand sell the end user this opportunity to move to a higher speed WBC EUAoption with accurate speed prediction.Customers can opt to stay with 8Mbps or upgrade to a higher speed. In the latter case,the CP will need to raise a modify order to upgrade to the ADSL2+ (up to 24Mbpsproduct) and the speed/billing of the upgraded EUA will be adjusted accordingly.Following installation of the WBC EUA service, the line will be allowed to stabilise duringthe first 10 days after provision and a Fault Threshold Rate (FTR) will be set at 15Mbps. A „slow speed fault‟ will be accepted if the line is operating below the FTR.Annex M (ADSL2)Annex M technology allows CPs to opt for more upstream bandwidth when placing anorder. This product variant allows WBC ADSL2+ circuits to achieve higherupstream speeds on the line of up to 2.5 Mbps. There is an added option to select theAnnex M product from the order screens, and customers will need to agree to specificcriterion, for example, loss of downstream speed is approximately 10%-15%.Please note that Annex M is not compatible with the ADSL2+ 8M transit product or the“FTRmodifiedCalc‟ option or on lines that return an Access Network Frequency Plan(ANFP) response of “LONG‟. As a result of this, there have been minor system changesto eCo Plus.Annex M details will be displayed during the Line Qualification check on the Pre-Order/Availability page if Annex M can be supported on the line specified. Details ofAnnex M are noted in the Annex M appendix in the WBC Product handbook.Issue 2 : 2011© British Telecommunications plcThis guide is for training purposes only and is subject to change by BTPage 8 of 111
