Bonding T1's on Dual port WIC

This is probably an easy question for anyone who constantly programs routers, but I am having an issue. I currently have a Cisco 2621 with two single port WIC's installed. These are bonded together using the config below (I have changed the IP addresses)

interface MFR1
 mtu 4470
 no ip address
 no ip redirects
 no ip proxy-arp
 encapsulation frame-relay IETF
 no ip route-cache cef
 no ip mroute-cache
 load-interval 30
 no arp frame-relay
 frame-relay multilink bid to gw
 frame-relay lmi-type ansi
!
interface MFR1.500 point-to-point
 ip address 1.1.1.1 255.255.255.224
 no ip redirects
 no ip proxy-arp
 no arp frame-relay
 no cdp enable
 frame-relay interface-dlci 500 IETF  
!
interface FastEthernet0/0
 ip address 1.1.1.1 255.255.255.240
 duplex auto
 speed auto
!
interface Serial0/0
 description To UUNET (u162377)
 mtu 4470
 bandwidth 1536
 no ip address
 encapsulation frame-relay MFR1
 service-module t1 timeslots 1-24
 no arp frame-relay
!
interface FastEthernet0/1
 no ip address
 shutdown
 duplex auto
 speed auto
!
interface Serial0/1
 mtu 4470
 bandwidth 1536
 no ip address
 no ip redirects
 no ip proxy-arp
 encapsulation frame-relay MFR1
 load-interval 30
 no arp frame-relay
!
no ip http server
ip classless
ip route 0.0.0.0 0.0.0.0 MFR1.500

I am replacing this with a Cicso 2811 and bonding them using a dual port WIC. Since we are eventually going to 4 bonded T1's. I have read where I need to configure the controller to use each port, and have attempted to do that several ways including using the ? after each word with the following results:

Cisco(config)#controller ?
  T1  T1 controller

Config(config)#controller T1 ?
  <0-0>  Controller slot number

Cisco(config)#controller T1 0?
/  

Cisco(config)#controller T1 0/?
  <0-1>  Controller subslot or port number

Cisco(config)#controller T1 0/0
                                ^
% Invalid input detected at '^' marker.

cisco(config)#controller T1 0/0
                                ^
% Invalid input detected at '^' marker.

Cisco(config)#

This router is running version 12.4.
Also, when configuring this for bonded T1's would the timeslots be evenly split like:
Channel-group 0 timeslots 0-12 speed 64
Channel-group 0 timeslots 13-24 speed 64
or are there different settings that would provide better support?

thank you,

What WIC is it?  The controller commands are likely only necessary for channelized-capable WICs; the others should simply appear as serial interfaces, and you should simply use the configuration you have now (with different port numbers as needed).

You do NOT want timeslots 1-12 and/or 13-24.  You want timeslots 1-24 on each.  Unless you're doing other stuff that you haven't told us about.

Well the reseller I purchased the router from mentioned I would need to do the controller settings, and sent me this link:
http://www.cisco.com/warp/public/116/t1_wic4.html
Now I did a sho config and this it what it showed about the controllers. Can you tell if this means I can just use the serial commands.

controller T1 0/0/0
 framing esf
 linecode b8zs
!
controller T1 0/0/1
 framing esf
 linecode b8zs
!
controller T1 0/1/0
 framing esf
 linecode b8zs
!
controller T1 0/1/1
 framing esf
 linecode b8zs
That link also was where I got the questions about the timeslots, which it looks like there are none configured right now on each controller and I need to do that. Is that correct?

In that case, the controller is used to define the physical layer attributes, but the corresponding serial interfaces are used to define the layer 2 and higher parameters.

Most likely, the controllers default to using all 24 timeslots, so you wouldn't need to define them.  No pain involved if you do though.

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Yes, the controller command had to be used to create the serial interfaces. I did not have any until I did that, and then I was able to enter my current config, minus the "service-module t1 timeslots 1-24" which was on the original Serial0/0 interface. From what I can tell this is used mainly on a single port T1 WIC. Here is what my config looks like now. Can you verify that this should work?

OK, why on earth do you have CEF turned off?

Otherwise, the config looks OK to me.

An error on my part, thanks for pointing that out. I was just concerned about getting the WIC's configured for bonding. Thanks for all of you help.
