Channels: 12
LMI: Ansi
Encaspulation: Frame relay
DLCI: 16

Frame Relay does not use username/password or CHAP.
interface Ethernet 0/0
  ip address  <== whatever your internal LAN is
  description Local LAN
  no shutdown
  ip nat inside
interface serial 0/0
  description T1 to ISP
  no shutdown
  no cdp enable
  encapsulation frame-relay
  service-module t1 timeslots 1-12
  frame-relay lmi-type ansi
interface serial 0/0.1 point-to-point
  description T1 frame-relay sub-interface
  ip address  <== whatever the ISP assigned you for IP
  frame-relay interface-dlci 16
  ip nat outside
ip route  <== whatever the ISP gave you as a default gateway
ip nat inside source list 1 interface serial0/0.1 overload
access-list 1 permit

At least the basics are done and you should be able to communicate.

  router# show frame-relay pvc  -- look for: DLCI 16  ACTIVE  Serial 0/0.1
  router# show interface serial 0/0  -- look for Serial 0/0 is up, line protocol is up
  router# show interface serial 0/0.1 -- look for line up, protocol up condition

Thanks for the config - I was able to get the router in an up/up state however my ISP does not allow any unauthenticated traffic through their network.  I had to use a virtual template interface to allow chap auth.  Thank you very much though
