Bonded T1s on a Nortel 1002 router

I have a Nortel 1002 with two T1s running into it. The router was configured with two networks running out of each of the two Ethernet ports. Now I just need one network, is it possible to bond the T1 ports or the Ethernet ports so I can the full 3Megs on one network as the 10.1.3.0 network can go away at this point. Posted below if part of the config.
module  t1 1
    exit t1
module  t1 2
    exit t1
interface  ethernet 0
    ip  address 10.1.3.1 255.255.255.0
    qos
      enable mon inbound
      exit qos
    exit ethernet
interface  ethernet 1
    ip  address 192.168.71.1 255.255.255.0
    qos
      enable mon inbound
      exit qos
    exit ethernet

I believe this is the part of the config that would be altered.

thanks in advance.
