I am trying to install an nm-16am module in a 2621 router using version 12.1(3r)T2 of the release software. The sho interfaces summary is not seeing the physical module and is not giving me an interface option in the config. But when I do sho version, it does see 16 terminal lines. Do I need an updated version of the IOS to support this module? If not, how do I get to a point where I can configure the interface?

Your IOS is fine and it sure is recognizing
this NM as you can see 16 terminal lines showing up in show ver output. However you
will not see any corresponding interfaces showing up yet in the config. Thats the way
its supposed to be. Instead, you will be seeing something line "line 1 16" or
"line 33 48" towards the end of your config.
Now corresponding to these tty/modem lines,
you will have to create async interfaces by
yourself if you want to do inbound PPP dialup. You can either configure indvidual
async interfaces, like int async 1 , int async 2 etc etc or a group-async interface with the group-range command to bundle all under one common configuration.

NM-16AM will not show up by default as the "Async interfaces" in the running config. But you should see "line 33 48" in the running config for that.
You need to create the "interface async 33" to 48 for those modems manually.
Or you can group all the async interfaces togather with following config
interface group-async 1
group-range 33 48
Once async interfaces are greated, you will see in "sh int summ"
