If you want to configure an ATM IMA backhaul, use the
ima-group command to assign the interface to an IMA group.
For a T1 connection, use the no-scrambling-payload to disable
ATM-IMA cell payload scrambling; for an E1 connection, use
the scrambling-payload parameter to enable ATM-IMA cell
payload scrambling.
The example assigns the interface to IMA group 0 and enables
payload scrambling.
Exits configuration mode.
