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

  • BOOK II Bell History and Strategies
    The Unauthorized Bio Of The Baby Bells 88 BOOK II Bell History and Strategies: Shareholders First, Customers Last What does the Star Wars' Evil Empire and Bell Atlantic Have in Common? James Earl Jones was the Voice of Darth Vadar and is the Voice Of Bell Atlantic— Are There Other Commonalties? The Unauthorized Bio Of The Baby Bells 89 "Food For Thought" Interlude— Conspiracy or Miscalculation? Book 1 leaves us with a serious dilemma, especially about the I-Way. First, we know straightforwardly that the plans were all scrapped and the announced services were never delivered. But we are left with wondering how both the telephone companies as well as their consultants, were so wrong. Let's look at the options: There were three massive errors in judgment: • Mistakes in the costs of rolling out the network • Mistakes in overestimating demand • Mistakes by the research/consulting suppliers Let's walk through each one: • Mistakes in the Costs of Rolling Out the Network: The original cost model for the I-Way was estimated at around $1,200 per household. However, Bell Atlantic stated that the cost of their trials came to $16,000 per line. This includes the cost of the various Info Highway components in the home, described earlier, as well as the cost of the fiber- optic networks. But, that's a difference per line of 1233%. Of course there are caveats. Most importantly, that the trickle of a rollout was only a "test" of advanced services, and with larger volumes of users, the costs would decline. In fact, Bell Atlantic's original plans may have actually called for a great deal less spending than $1,200 a line.
