determining compatibility between cisco parts?
Posted on 2011-03-22
I'm trying to learn a more general concept here, but I'll use a specific example.
We have a location that needs four T1's coming into it. And there'll probably be a need for more over the next two years.
Cisco makes a card VWIC3-4MFT-T1/E1 that has 4 T1's on it. How do I determine:
1. Whether this card will work with:
a. a Cisco 1841 router (which we have, on hand, right now)
b. a Cisco 2811 router (which we are familiar with, but would have to order)
2. Assuming the 4 T1 card can be used, how do I determine what limitations on expansion are? For example, the 2811 has 4 slots in it. Could I use 4 of the 4-T1 cards for a total of 16 T1's? (I understand this is not a realworld solution, I'm simply using it as an example).
Please note that I am not asking for the answers to the specific questions. I'm asking how would - I- determine the answers to the questions.
Is this something I would open a TAC case on?
