According to next document:

http://www.cisco.com/en/US/products/hw/routers/ps274/products_data_sheet09186a0080091b8b.html

the NM-4T module is not supported at 2600 series (except 2691 model, see Table 7 Supported Platforms).

I'm having the same problem with NM-4T with a 2610 xm router . I would like to know what is the correct card to use.

Hi Andrea

I think the best choice (and perhaps the only one) is to use a Network Module NM-2W with two WAN Interface Cards WIC-2T, so your router will have 4 serial ports.

Here you are some info about this cards:

The Serial NM-4T physically fits perfectly in my router 2621. I bought them because the seller assured me they work with any 2621 IOS. I noticed on cisco's website, under platform support for the NM-4T, that it is not supported.

However, is there a workaround, or a 16MB IOS that will allow me to use the NM-4T? I need to practice with it in a non-production environment.
