using E1s spanned over long(1000km) distance with IMA makes problem i.e. causing drops in packets in this case maximum differential delay being used is 25ms i have also tested the same thing over greater max. differential delay(100ms).
But using the same E1s without IMA causes no problem but this is not a solution & causes lots of overhead, i've to exploit IMA.....
One more thing using E1s in IMA spanned over short distances are working perfect.
Any comments would be helpful
