Dear Mr. Bibic:

Re:   Bell Canada application regarding recovery of wireline costs to enable wireless number portability

On 12 May 2006 , the Commission received an application by Bell Canada ( Bell ) requesting that it be allowed to recover that portion of the costs incurred by the company to modify the wireline network to enable wireless number portability (WNP) through an exogenous adjustment.   In addition, Bell requested that certain associated wireline revenue losses which are solely attributable to the introduction of WNP be recovered from the company's deferral account.   On 16 August 2006 , the Commission posed interrogatories to Bell Canada .   Bell Canada submitted its interrogatory responses on 24 October 2006 .

Bell is requested to provide responses to the attached questions by 4 December 2006 .     The company is also requested to provide a copy of the questions for the public record, for posting on the CRTC web site, and provide a copy to interested parties, within two business days.

Yours sincerely,
