RE: 2620XM vs. 1721 Routers [7:74727]
Hi John, You will definitely lose certain IOS functionality with the 1721. Newer code has more features and needs more memory. The 2620XM that you speak of has support for 128MB ram and 48MB flash while the 1721 is much much lower. Also note that as you start getting into 12.2 and 12.3 advanced features your memory requirements go to 96MB and even 128MB for DRAM. Depends on your needs for the various features. Your best bet is to decide what features you need (routing protocols and then other features). Then go to cisco.com/go/fn and find a router that supports those features. While there are many features you may not get with the 1721 - you also may not need them so why spend the extra money on the 2620XM for a simple serial connection.

Hi John, What I've found is that you can't run an Enterprise IOS on the 1721. No IS-IS protocol.

RE: 2620XM vs. 1721 Routers [7:74727]
In addition to the performance differences, I know there are some functionality differences with the IOS images. Don't know them off the top of my head, but there are some things you can do on 2600 that you can't do on 1700.

2620XM vs. 1721 Routers [7:74727]
I'm not very familiar with the 1721 routers and while I'm researching them I wanted to get some opinions. Isn't the 1721 really just a baby 2600 with a slighly smaller processor and no network module slot? Are there any other significant differences between them? We've been using 2600, and later the 2620XM, but we've recently got rid of the need for a network module, leaving us with a current need of one WIC. It seems like a waste of money to buy a 2620XM if we're only going to pop a WIC-2T into it. :-) I'm sure there's a performance hit, but it's not like I'm trying to drive a DS-3 with this thing. I'll need a T-1 connection, a low-speed serial connection, and fast ethernet. Nothing too fancy. Any thoughts?
