Re:   Competitor Digital Network Services

T he Commission is in receipt of Tariff Notice (TN) 7091 from Bell Canada and TN 146 from Bell Aliant Regional Communications, Limited Partnership (Bell Aliant),(collectively, the Companies).   These applications relate to changes to Competitor Digital Network (CDN) services and are supported by a cost study provided by Bell Canada.   Bell Aliant submitted that the proposed changes to its CDN services tariffs in TN 146 correspond to those proposed by Bell Canada.

To assist the Commission in disposing of these applications, the Companies are requested to provide responses to the interrogatories set out in Attachment 1 by 28 February 2008.

The above material is to be filed by the date set out above, and must be received, not merely sent, by that date.

Yours sincerely,

Original signed by

Yvan Davidson
