Sec.  52.27   Deployment of transitional measures for number portability.

   (a) All LECs shall provide transitional number portability measures, as
   defined in section 52.21(q) of this chapter, 47 CFR 52.21(q), as soon as
   reasonably  possible  upon  receipt of a specific request from another
   telecommunications  carrier,  until  such time as the LEC implements a
   long-term database method for number portability in that area.

   (b)  A LEC must provide the particular transitional number portability
   measure requested by a telecommunications carrier, except as set forth in
   paragraph (c) of this section.

   (c) A LEC that does not provide a requested transitional number portability
   measure must demonstrate that provision of the requested transitional number
   portability measure either is not technically feasible or if technically
   feasible, is unduly burdensome.

   (1)  Previous successful provision of a particular transitional number
   portability measure by any LEC constitutes substantial evidence that the
   particular method is technically feasible.

   (2) In determining whether provision of a transitional number portability
   measure is unduly burdensome, relevant factors to consider are the extent of
   network upgrades needed to provide that particular method, the cost of such
   upgrades, the business needs of the requesting carrier, and the timetable
   for deployment of a long-term number portability method in that particular
   geographic location.

   (d) LECs must discontinue using transitional number portability measures in
   areas where a long-term number portability method has been implemented.
