Common use of Denial/Restoral OSS Charge Clause in Contracts

Denial/Restoral OSS Charge. In the event CLEC-1 provides a list of customers to be denied and restored, rather than an LSR, each location on the list will require a separate PON and, therefore will be billed as one LSR per location. Cancellation OSS Charge CLEC-1 will incur an OSS charge for an accepted LSR that is later canceled by CLEC-1. Note: Supplements or clarifications to a previously billed LSR will not incur another OSS charge. Threshold Billing Plan The Parties agree that CLEC-1 will incur the mechanized rate for all LSRs, both mechanized and manual, if the percentage of mechanized LSRs to total LSRs meets or exceeds the threshold percentages shown below: Year Ratio: Mechanized/Total LSRs 1999 70% 2000 80% 2001 90% The threshold plan will be discontinued in 2002. BellSouth will track the total LSR volume for each CLEC for each quarter. At the end of that time period, a Percent Electronic LSR calculation will be made for that quarter based on the LSR data tracked in the LCSC. If this percentage exceeds the threshold volume, all of that CLECs’ future manual LSRs will be billed at the mechanized LSR rate. To allow time for obtaining and analyzing the data and updating the billing system, this billing change will take place on the first day of the second month following the end of the quarter (e.g. May 1 for 1Q, Aug 1 for 2Q, etc.). There will be no adjustments to the amount billed for previously billed LSRs. EXCLUSIONS AND LIMITATIONS ON SERVICES AVAILABLE FOR RESALE Exhibit B Page 1 of 2 Type of Service AL FL GA KY LA Resale?
