I need to connect my 1750's WIC1T to a T1 that only provides 512K on slots 1-8.

Cisco 1750 router.  12.2(8)T code.
I need to connect my 1750's WIC1T to a T1 that only provides 512K on slots  1-8.
On my 2600 router, which I am replacing, I used the following command to accomplish this:  service-module t1 timeslots 1-8
That command is not available on the 1750!
Is it a limation of the WIC1T?
If not, what is the command I need to do this?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this from an example on Cisco.com (I'd post link but you need CCO login)

T1 Configuration Example (w/frame relay)

This section shows a T1 configuration example for Router A, a Cisco 1700 series router. (See Figure 5.)

card type t1 0
controller T1 1/0
  framing esf
  linecode b8zs
  channel-group 0 timeslots 1-24
interface Serial 1/0:0
  no ip address
  encapsulation frame-relay
  no keepalive

interface Serial 1/0:0.1 point-to-point
  ip address
  frame-relay interface-dlci 100


For the WIC-1T, that is only a serial interface that requires an external CSU/DSU
WIC-1DSU-T1 takes the service-module commands
VWIC-1T1MFT takes the controller/channel-group commands that Gary posted above, execpt
 channel-group 0 timeslots 1-8
