Can I add a 3rd T1 connection on Cisco 2651XM router? If yes, how?

Unanswered Question
Jul 16th, 2007

I have a 2651 with one T1 card. Both slots on this T1 are occupied as I have 2 T1's coming in already. Now I want to add more bandwidth to my internet connection and purchased a 3rd T1. How do I add this 3rd T1 to my network?

I am not sure if I can add a second T1 card to 2651XM? If anyone knows, plz let me know.


Do I need to add another router in parallel to 2651?


Do I need to purchase a saprate router that can support 3 x T1's and get rid of 2651?

Your help is much appreciated.

I have this problem too.

you can use the WIC-2T or the VWIC-2MFT-T1.

The 2651Xm has two WIC slot so you can support up to four serial links using the cards above.

I would recommend the second because you can connect the circuit directly without external CSU/DSU, hence monitoring the circuit much better.

There is really no need to replace the router just to have it support 3 T1s.

Hope this helps, please rate post if it does!
