Subject: Use of the Local Exchange Routing Guide (LERG) for network notification
The Local Exchange Routing Guide (LERG)1 is currently the only common North America-wide vehicle available to telecommunications service providers for exchanging network change notification information. To ensure that calls are routed and rated in the most efficient and transparent way possible, it is critical that all required fields of data be accurately populated, in the appropriate database(s), in a timely fashion. It is equally important that service providers utilize the LERG to effect the network changes required to maintain the integrity of the North American telecommunications system.
Commission staff has received a number of complaints from both Canadian and U.S. entities with regard to the following:
As the entire North American telecommunications system makes use of the LERG to ensure network changes are implemented, errors or omissions may cause serious routing problems, blocked calls, billing errors and the loss of revenue.
This letter is to remind all Canadian telecommunications service providers that, as established in the Canadian Central Office Code Administrative Guidelines, the LERG is the vehicle which should be utilized to exchange network change information. Data which is input to RDBS and BRIDs must be complete, accurate and submitted in a timely fashion, and network changes identified via the LERG should be implemented in all networks by the effective date.
Service providers are requested to review their processes and take the necessary action to correct errors and eliminate omissions in the RDBS and/or the BRIDS. Service providers are to confirm with the Commission, no later than 1 December 2000, that all necessary action has been completed.
