Mr. Brian Armstrong Dear Mr. Armstrong : Re: SaskTel Tariff Notice 88 - Competitor Digital Network (CDN) Services The company is requested to provide comprehensive answers, including any supporting information, to the attached questions with regard to the above referenced application by 28 September 2005 . Yours sincerely, 'Original signed by S. Bédard '
Suzanne Bédard Attachment With reference to SaskTel's 8 August 2005 reply to comments received from MTS Allstream Inc. with respect to SaskTel Tariff Notice 88, at paragraph 6, the company indicates it uses the following rate application approach when applying charges in its retail Digital Network Access (DNA) and Competitor Digital Network tariffs for both DS-1 and DS-3 intra-exchange channels: In exchanges with more than two wire centres, SaskTel designates one of these wire centres as a "main" wire centre. In situations where two accesses that are served by different wire centres must be interconnected to meet customer needs, one or two channel charges are applied. The number of channel charges applied depends upon the wire centres that serve each access. If one of the wire centres is the "main" wire centre, then only one channel charge is applied. However, if neither of the wire centres is the "main" wire centre, two channel charges are applied. SaskTel has incorporated this concept into its cost studies by determining the average cost of an intra-exchange channel running between two wire centres . 1. Explain whether SaskTel's current approach with regard to the application of rates and charges for DNA intra-exchange channels is specifically indicated in its tariffs. If so, provide the precise tariff reference(s). If not, explain why not. 2. Identify all exchanges in SaskTel's operating territory with more than two wire centres. For each of the exchanges identified, indicate the name and civic address of the wire centre designated by SaskTel as the "main" wire centre. 3. With regard to exchanges with more than two wire centres, provide schematics for all existing configurations of interoffice intra-exchange transmission facilities. The response should identify all major resource components (e.g., electronic/optical hardware, frames, multiplexers, patch panels, etc.) of the facility. 4. For each of the exchanges with more than two wire centres, provide an inventory of all in-service DNA DS-3 intra-exchange channels for every switching centre pair within that exchange. The response should identify specific wire centre names and civic addresses, the type of facility configuration involved (e.g., whether an intermediate wire centre is involved), and the quantity of DS-3s provisioned using each specific configuration. 5. For each of the exchanges with more than two wire centres, for both DNA DS-1 and DNA DS-3 intra-exchange channels:
6. With reference to Bell Canada's response to Bell(CRTC)11Oct02-315 CDNA, provide justification as to why SaskTel should or should not use the same approach for developing intra-exchange channel service costs (i.e., for each exchange with more than one switching centre, develop the cost of intra-exchange facilities for every switching centre pair within that exchange for each of the required transmission speeds, and determine the average cost for intra-exchange facilities for each speed by weighting the results for each exchange by the current demand for DNA accesses in each exchange). 7. Provide a cost study for SaskTel's DNA intra-exchange channel service, assuming SaskTel were to use the same approach as that of Bell Canada described in its response to Bell (CRTC)11Oct02-315 CDNA using the demand forecast provided in response to question 5. cc: Bob Martin, CRTC (819) 953-3361 Date Modified: 2005-09-29 |
