AT&T Southwest -- -- A planning tool designed to help carriers identify the most efficient AT&T Southwest tandem to assign their codes in the Telcordia LERG, based on the Rate Center being served. This file includes the geographic map by state. Download the data file by region Rate Center specific information AT&T Southwest has developed a "" (Plan) to optimize interconnection in its network and minimize capacity bottlenecks at constrained tandems. The Plan is intended to ensure Competitive Local Exchange Carriers and Wireless Service Providers adequate sizing of trunks and available capacity for additional growth at all AT&T Southwest tandems. The is a recommendation for carriers to use when designing their network to identify the most efficient AT&T Southwest tandem in which to assign their codes in the LERG based on the Rate Areas being served. The AT&T Southwest identifies every AT&T rate center in a LATA in which AT&T is the Local Exchange Carrier providing service. The Plan principally identifies the AT&T Southwest Tandem Homing Arrangement by Rate Area, thereby allowing Carrier's homing architectures to resemble AT&T's homing architecture. AT&T Southwest is recommending Carriers utilize the tandem associated with the rate center, as identified in the Plan when entering the tandem in Telcordia's Routing Database (LERG) for each NXX allocated to the Carrier.
