[c-nsp] T1 w/ integrated CSU/DSU module - high density NM - does it exist?

[Joel M Snyder]

I've noticed that our T1 business is dropping off in favor of Ethernet business 
and I'm trying to do some device consolidation.  I'm looking for some NM for 
36xx/37xx/38xx routers that can handle more than 2 T1s with integrated 
CSU/DSU---and I'm beginning to think that they don't exist.

I have a 4-port ATM IMA card, but that doesn't present the controller as a 
separate device so you can't go 'around' the ATM SAR the way you could with, for 
example, an MFT port on a MC3810.

So: is there something I'm missing?  Can I run standard T1s (non-ATM) into a 
4-port or 8-port ATM card?

If not... is there anything other than buying 2W NMs and stuffing them full of 
T1 ports?

I already have enormous numbers of 4-port serial cards, but I'm trying to get 
rid of our external CSU/DSU boxes and just run the T1 straight into the router.

Am I nuts or does Cisco not handle this case?
