Routers 3600 - T1 question.

[hellboy101]

Hello all-

We have a Cisco 3600 router handling 3 current T1 connections but I need to add 2 additional T1 lines for the corporation. Can the 3600 handle a total of 5 T1's? physically don't know if it has enough T modules but if so, would I need to upgrade my IOS rev? or just setup the T's.. current ver on my router is Version 12.2(3)

thanks to everyone!

Can't see why not, we're running 6 of them on a 2691, using VWIC2-MFT-T1 cards.

 

[hellboy101]

thx, would you happen to know what the latest IOS ver is out there that would run on the 3640? we currently have 12.2

[artesian2000]

Unless you have to why upgrade the IOS?

 

[hellboy101]

Thanks again

Hi artesian..

I had a question. i did a sho ver on the 3640 router, it gave me all this great info and specifically that I have 5 channelized t1/PRI port(s)..

Now looking at the physical backside of this router, i have
on the upper left hand side of the router an FE-PRI 1 FE -1 CT1-CSU, now on the left bottom hand side I have 1FE-2W (Fasteth0) and on the right bottom hand side I have 2w vwic 2mft-t1).

My question is that I currently have 3 T1's running on this router.. based on what I mentioned above, could it sounds as though I need one more T1 port. Am i correct? Can I utilize the upper left hand 1FE-1CT1-CSU port for my fourth or fifth T1 connection? and can I use my one available bottom right port (out of the 4) in order to establish either my 4th or 5th T1?

Thanks for any help you can offer Artesian

Based on your config it looks like you have 2 controller not configured. So you have the abilty to hook up 2 more t-1's

Thanks Artesian! I appreciate it..

Hello Artesian-

Hope all is well. I had one additional question based on our T1 port chat previously.

Based on the T1 assessment below, by viewing this, is it telling me that I "physically" and "currently" have 5 T1 controller cards "placed" in the router as it stands "or" is it telling me that I have the ability to "add" two more T1 cards to the back of the router.. Would you also know why the number controller T1 3/0, is so much different from the others? they all start with T1 0/x
