N.Y. Eyes Strategy for Number Portability
The New York Public Service Commission (PSC) has endorsed location routing number (LRN) technology as the most viable long-term solution to telephone number portability, although it does not expect LRN to become generally available for installation on most major central-office switching equipment until the second quarter of 1997.
The PSC noted that LRN minimizes the impact on network architecture by preserving existing routing logic and hierarchy, thus minimizing switch modifications and changes to databases and operating systems.
