Ok first timer here.... I am trying to setup a Cisco 3745 with a T3/E3 module for a new T3 line.
The line is being activated today. BRN lines are all setup T3/E3 module installed in Cisco 3745. It recognizes the module and have done the interface and controller # throught the command line interface.
the ISP has provided me with my IP Configurations for the new line. The Cisco is being used as the DSU/CSU then running into a Watchguard firebox X series 750e firewall. So my question is more of proper configuration. Where or what interface do I assign the IP configurations provided to me by the ISP?  Are they assigned to an interface in the Cisco or the WAN interface on the Firebox?

Typically you put the IP configurations on the T3 port (Serial 1/0 or whatever your port is).  Then use one of the other interfaces on the router to uplink your firewall to.  We use a /30 private network to put these uplink ports on.

I was thinking I should be able to assign the Public IP configurations to the T3 interface
cisco3745>enable
password: xxxx
cisco3745# configure terminal
cisco3745(config)# controller T3 1/0
cisco3745(config-controller)# ?

The command option I am given for the T3 controller are:  BERT, Cable Length, Clock, Default, Description, Exit, Framing, Help, Loopback, MDL, No, and Shutdown

I can not find anywhere for an IP configuration.

I sat down and figured it out myself.
I was in ( config-controller )  for the T3 module not in the  ( config-if ) for the T3 module
