Routing customer calls is essential to your operations.  To ensure successful call completion, your routing information must be published according to the industry standards in the Telcordia® Routing Administration (TRA) LERG^TM Routing Guide to be disseminated to all other providers.  JSI is contracted with Telcordia as a designated TRA administrator for the Administrative Operating Company Number (AOCN) service.  As such, JSI has access to the Business Integrated Routing & Rating Database (BIRRDS).  In its administrator role, JSI enters all necessary information for the LERG, including the following:

• NPA-NXX
• NPA-NXX-X (block assignments)
• Rate center
• Switch CLLI codes
• Tandem homing arrangements
• Location routing numbers (LRN)

With more than a decade of AOCN experience, JSI offers the assurance of timely and accurate LERG database updates made on your behalf.  Network Services staff also assist with ordering NPA-NXX or NPA-NXX-X assignments in NANPA's Numbering Administration System and the NeuStar® Pooling Administration System, respectively.
