In the first WIC certain parts of the config go under the interface and service module-t1.  In the second WIC there is a totally seperate part of the config called controllers - why is that?

What is the WIC model number?
Looks like the T1 (1 port) WAN daughter card is a VWIC-1MFT-T1, it uses "controller t1 x"
WIC-1DSU-T1 just uses a serial interface with service-module commands.

you are exactly right about the WIC model #'s as far as I can tell, yes

What exactly is controller t1?  Why does the VWIC have this option while a standard WIC does not?  This isn't a matter of better or worse I know, I just want to fully understand what hardware I have  - I know this VWIC can carry voice as well, correct? Even though I am not using them for that.  They were just here when I got here.

Just different purposes. The controller card can be used as a voice gateway to a PBX, where the DSU can only be a data line. You can get a 2-port MFT card with "drop and Insert" capabilities that lets you crossconnect T1 channels to have both data and voice coming in on a single T1, and cross-connect the voice channels out the 2nd port to a PBX..

ah - i think the standard CSU/DSU WIC    WIC-1DSU-T1    will do for any purposes I have, any future WIC purposes - thanks for the info.
