Issue 1 Chapter 1 General The TruOps Telecom Routing Administration (TRA) LERG™ Routing Guide (LERG) provides routing data obtained from the iconectiv Business Integrated Routing and Rating Database System (BIRRDS) into which data is entered by Service Providers (SPs) and/or their agents. The LERG is a snapshot of information contained in BIRRDS at the point in time a given LERG is produced. Close of business on the last working day of each month is the cutoff for the data in the LERG that is dated the first of the following month. The LERG reflects the current state of active network data and as well as future activity within the North American Numbering Plan (NANP), as reported by SPs. The basis of the LERG is a requirement set by the 1984 MFJ (Modified Final Judgment) for the then Regional Bell Operating Companies (RBOCs) and GTE, to provide points in their networks (e.g. tandems and switches), to where specific calls (based on NPA NXX data) could be routed by interexchange carriers, and especially as a means to notify others when changes in that routing data are scheduled to occur. Independent Local Exchange Carriers had their data maintained by the RBOCs, and have evolved to maintain their own data or have arranged for their data to be maintained in the TRA database by third party companies that provide various services to ILECs. Future activity should be reported in line with industry notification timeline guidelines, but ultimately is the responsibility of each SP. Most data value changes encompass activity that is to occur within the next 6 months, although data can be reported as far in the future as a SP may deem reasonable and necessary. The current state of active network data appears in the LERG with a blank STATUS code and
