Here are the two methods on how to bond T1s. There may be more methods to do so, but these two are probably the most commonly used in most environments.

Below is how to bond two T1s. You can definitely add more if needed.

Router (config) # interface s0/0/0
 service-module t1 timeslots 1-24
 encapsulation ppp
 ppp multilink
 ppp multilink group 1
!
interface s0/1/0
 service-module t1 timeslots 1-24
 encapsulation ppp
 ppp multilink
 ppp multilink group 1
!
interface multlink1
 ip address x.x.x.x y.y.y.y
 ppp multilink
 ppp multilink group 1

Second method is how to bond three T1s using Frame Relay encapsulation. You can definitely add more T1s if needed.

interface MFR1
 frame-relay lmi-type cisco
!
interface MFR1.XXX point-to-point
 ip address x.x.x.x y.y.y.y
 frame-relay interface-dlci XXX
!
interface Serial0/0/0
 encapsulation frame-relay MFR1
 service-module t1 timeslots 1-24
 no arp frame-relay
 frame-relay multilink lid first-link
!
interface Serial0/1/0
 encapsulation frame-relay MFR1
 service-module t1 timeslots 1-24
 no arp frame-relay
 frame-relay multilink lid second-link
!
interface Serial0/2/0
 encapsulation frame-relay MFR1
 ip route-cache flow
 service-module t1 timeslots 1-24
 no arp frame-relay
 frame-relay multilink lid third-link
!

I hope this has been helpful and I thank you for reading!
