I'm in a position where I may be working with Nortel gear either directly or indirectly (I.E. supervising and/or just the system in the next office) and I'm wondering if there's any books or web resources that would be a good basic intro to Nortel terminology. What cards do, how the system is set up ins oftware, etc. I'm not expecting to be a wiz, but I was in the position of being the customer for some work on one of my company's systems for overnights on a move and it was frustrating not knowing what cards do, and I felt like I wasn't comfortable making decisions during that weekend because I didn't know the seriousness of things.

I normally run a Tadiran PBX and it seems I do a lot more hands-on work than our NYC PBX systems (that have a lot more work done by vendors due to union rules) but I'd feel better at least knowing which cards do what!
