TELUS Communications Company – Destandardization of Digital Channel Service

File numbers: TCBC Tariff Notices 4342 and 4342A
TCI Tariff Notices 630 and 630A

1.         The Commission received applications by TELUS Communications Company (TCC), dated 16 December 2010 and amended 20 December 2010, in which the company proposed revisions to item 665 of its General Tariff for Alberta and item 440 of its General Tariff for British Columbia. Specifically, TCC proposed to destandardize Digital Channel Service (DCS)[1] for all speeds below 56.0 kilobits per second (Kbps).

2.         TCC submitted that the equipment used to provide DCS at speeds below 56.0 Kbps is no longer being manufactured and that the demand for this service is very low. In addition, TCC indicated that the last two DCS circuits were installed in October 2008 and October 2009. TCC also submitted that the client base for this service had declined by 11 percent in Alberta and by 18 percent in British Columbia between May 2009 and May 2010.

3.         TCC proposed to allow its current DCS customers to keep their existing service following approval of its request for destandardization, but not to permit any service changes or moves. TCC submitted that it would offer DS-0 Digital Network Access service,[2] which provides the same functionalities as DCS, to new customers and to current customers who request moves or changes to their DCS service.

4.         The Commission received no comments regarding TCC’s applications. The public record of this proceeding, which closed on 2 February 2011, is available on the Commission’s website at under “Public Proceedings” or by using the file numbers provided above.

5.         The Commission notes that TCC has notified its DCS customers of its intention to destandardize the service and has identified a service alternative.

6.         The Commission considers that TCC has complied with the requirements set out in Mandatory customer contract renewal notification and requirements for service destandardization/withdrawal, Telecom Decision CRTC 2008-22, 6 March 2008, in which the Commission revised its procedures for dealing with applications to destandardize and/or withdraw tariffed services.

7.         Accordingly, the Commission considers that TCC’s proposal to destandardize its DCS is acceptable.

8.         In light of the above, the Commission approves TCC’s applications, effective the date of this order.
