NXX (NXD-A) Records

As a reminder, when codes are assigned for LRN purposes, pool replenishment purposes
or for a Dedicated Customer (if applicable), please create the NXX Record (NXD-A) in the
Telcordia™ Business Integrated Rating and Routing Database System (BIRRDS), so the
PA can proceed with creating the Block Code Record (BCD) for the assigned thousands-block(s).
