I'm an auditor trying to figure out EOE/EOL IOS releases. I think I have issues with some of the releases we have. But before I make that comment on an audit I want to be certain.
I have a number of 2610XM's with 12.2.(13)T16. I think that version has reached it's EOE based on Product release lifecyle. Would this release be part of the 12.2T family? Any help would be fantastic.
Early in Ciscos history, the need for at least two trains for releasing Cisco IOS Software emerged:
1) A train for bug fixesmainline
2) A train for bug fixes and new featuresT train
With two trains, Cisco could introduce new features in a Cisco IOS release from one train without affecting the code base of the other train.
Mainline trains, such as 12.2, are built from previous generation T trains, such as 12.1T. Mainline trains, such as 12.2, are parents of other trains, such as 12.2T
Additional information regarding IOS can be found in the following white paper:

Hope this answers your question.

You are correct. According to the last link I posted, it says 12.2T train EOE was Nov 2004. T stands for the T train.
