Is there any way to verify that all 24 of my T1 DS0s are "active" when using the Fractional T1 CSU/DSU module on a 26xx ? The "show controllers" command doesn appear to provide this information, and "show interface" says "BW 1544 Kbit" but I'm wondering if that is just cosmetic.
Also, If I do have a full T1 from my provider, do I need to specify this with the "service-module t1 timeslots 1-24" command or is no config neccessary ?
Not sure. No, if you have a full T1, no service-module command is req'd.

There's no programatic way to test this with the cisco. If you configure all 24 timeslots, and bring up your data circuit and have layer-3 come up, then you have all 24 timeslots. Ie. data transmission uses all channels configured, and if you don't have them, you won't get data transmission through end-to-end. Of course, you could configure 12 timeslots on each side even if you have 24 and still work fine.
Thats the default on the WIC-1DSU-T1 (or -V2) card (which I'm assuming you have instead of some of the other T1 cards). So, you don't need to specify it, because thats already configured.
