Not quite - there are a bunch of CS2K retirements listed there, which was the soft switch evolution of the DMS100. I'm personally a little sad about those retirements as my first professional job was on the small team at Nortel developing the prototype of a DMS100 call server controlling a packet switch fabric. We started with ATM but moved to Ethernet when it became clear that was going to be the packet fabric of choice. Still, it's had a good innings and they were fun times.
I hadn't heard the name Nortel in a long time - I used to work for a company that had a lot of Nortel phone switches. Wikipedia says that they're now defunct, which makes me a little sad.
The dot-com bubble, mismanagement, and accounting shenanigans took it from being ~1/3 of the entire value of the Toronto Stock Exchange and an employer of almost 100K employees to bankruptcy within the span of a decade.
