Hello Cisco-Community,
we use a Cisco 3660 Router with NM-2W module to get a total of 16 E1 G.703 interfaces (8xVWIC-2MFT-G703). Now we want to replace this router with a new one. As the NM-2W are not on sale anymore and ISR2 are not compatible I need a suggestion how to handle this problem. Is there a single router avaiable which can take a total of 16 E1 interfaces? We know about the VWIC3-4port E1 Module, but G.703 support is missing here.

Check that if you configure 31 timeslots on the remote router also, that will it will work fine at 1984 Kbps over unframed circuit.
Other than that you can use any ISR G2 router.

I am talking about 16 physical E1 G.703 connections. I have 16 E1 cables arriving at this router.

Correct. And if you read and understand my post above, you will learn how you cna use a regular E1 interface instead of the more expensive G.703 version, that in most cases is not necessary.
