On the Telus page, there are two packages.
Optik High Speed and the other is High Speed Turbo. I have High Speed, which is the 15Mb package.

At the time of my subscription, the Optik TV @ 15Mb package was extra. They probably realized that 5Mb (or whatever it was) wasn't sufficient for TV and Internet.
