I may be missing the point, but I thought a DDF was just where you wired
up the E1's too ..
Is there any active box in between the 2 x routers, providing clock ?
Have you tried with BOTH ENDS set to internal clocking ?

Both interface using same config as follow :
ce1-2/0/0 {
description "*** RouterA ***";
clocking external;
e1-options {
framing unframed;

no-partition interface-type e1;
}
e1-2/0/0 {
description RouterA;
mtu 4500;
clocking external;
encapsulation cisco-hdlc;
unit 0 {
family inet {
address xxx.xxx.xxx.xxx/30;
}
family iso;
family mpls;
}
}
And the other :
e1-1/0/1 {
description RouterB;
mtu 4500;
clocking external;
encapsulation cisco-hdlc;
e1-options {
framing unframed;
}
unit 0 {
family inet {
address xxx.xxx.xxx.xxx/30;
}
family iso;
family mpls;
}
}
Transmission using DDF

And on the other end ?
What is providing the clock ?
What is the box on the other side ?
If they are directly connected, i.e. no SDH or so in the middle ... try
clocking BOTH ends as internal.

But if we ignore the restarted router, why should i have to unplug/plug E1
cable facing to peer router to make it work again.
I believe that keepalive is kind of setting to make interface know while it
is up or down. But after several times, link cannot revert back to normal
until unplug/plug ritual.
That should not happen IMO ... there must be something else up .. timing
?
However are you clocking the circuit ?
