Re: Number Pooling


Siemens Stromberg-Carlson (SSC) supports the ‘Pre-Porting’ option as the long term solution for number conservation using the NPA-NXX-X/LRN method. With this position, SSC would support the following:



Because this capability is a departure from the established LNP requirements for call handling, there would be switch impacts to accomplish this. SSC can have this implementation available for the January 1, 1998 date.


As it is likely that the solution established from this committee will be adopted as the defacto standard for other number conservation efforts. SSC would like to encourage the committee to pursue ‘Pre-Porting’ using the NXXX/LRN method as the number pooling solution.


If there are any questions or concerns regarding SSC’s position please contact Tom Bainbridge at 561-955-8305 or e-mail:
