Interrogatories for Bell Aliant and Bell Canada
1 a) Provide a complete description of the provisioning process, including a circuit diagram, required to establish a CDN DS-1 access circuit, identifying the facilities and activities required to establish the circuit. Identify any additional facilities that are required to provide B8ZS line coding on the circuit, and identify the stage in the provisioning process where these facilities are added. Further identify the expenses associated with any additional activity that is required to provide B8ZS line coding on the circuit, and identify the stage in the provisioning process where each of these activities is undertaken.
b) Explain whether any of the additional facility costs or expenses required to provide B8ZS line coding were included as part of the CDN DS-1 access service in the cost studies filed in the proceeding that led to Telecom Decision CRTC 2005-6. If these costs were not included in those cost studies, explain why they were excluded.
2. Bell Aliant's Access Services Tariff Item 130 defines a Competitor Digital Network (CDN) DS-1 access circuit as a channel capable of digital transmission at a 1.544 Mbps rate (page 48.1, Tariff CRTC 21562). The current tariff for Bell Canada (Tariff CRTC 7516) provides no comparable definition for the bandwidth provided by a CDN DS-1 circuit for the same tariff item.
a) Confirm that Bell Canada has the same definition of a CDN DS-1 access circuit as Bell Aliant. If so, provide revised proposed tariff pages to reflect that definition. If not, explain the difference in the definition, with supporting rationale.
b) Explain whether the DS-1 bandwidth defined in the tariff refer to the usable bandwidth available to the customer. If not, explain what bandwidth the customer will receive with rationale.
3 a) For each of Bell Aliant and Bell Canada, provide the total number of new CDN DS-1 access circuits for which the Companies have applied the service charge identified in Special Facilities Tariff D21(b)(1) (Tariff CRTC 21563 for Bell Aliant and Tariff CRTC 7396 for Bell Canada) since the date of Telecom Decision CRTC 2005-6.
b) Identify the different circumstances under which the service charge has been applied or would apply.
4. Tariff Item D21 in Tariff CRTC 21563 and Tariff CRTC 7396 describes the service charge D21(b)(1) as a charge that applies to a DEA access facility or a standard Digital Private Line channel that is provisioned end-to-end on fibre optic or copper facilities added coincident with the installation of Digital Private Line circuit(s). Provide the rationale for the Companies' application of this tariff to a CDN DS-1 access circuit.
