Question : Cisco 2801

I have a brand new out of the box 2800 series router.   I need some help building the frame-relay config.  I have 7 remote sites all with point-to-point T1's.  Now, I've worked with other routers before and the config is pretty stright forward but with this router I do not have "interface serial" command.  I have no options to setup any serial interfaces.  

I think maybe I don't know how to configure frame relay on this router.  Here is my config, version info and what options I have under the interface command.  If anyone can help with a sample config or point me in the right directoin that would be great.  Perhaps I need a different ios?

Answer : Cisco 2801

Continuing with what rage419 stated above:
  controller T1 0/1/0
    channel-group 1 timeslots 1-24

That command will then automagically create a new serial interface:
  interface serial 0/1/0:1  <== corresponds to controller 0/1/0: channel-group 1
   encap frame-relay

Now you can go ahead and create all the sub-interfaces you need

  interface serial 0/1/0:1.1 point-to-point
   ip address z.b.c.d 255.255.255.252
   frame-relay interface-dlci 16

 interface serial 0/1/0:1.2 point-to-point
   ip address z.b.c.f 255.255.255.252
   frame-relay interface-dlci 17
