Satish,
I do not know about the ericcson line
variant however i know the lucent family.I think from experience i will
advise that you let a Ericcson AXE TDMA do exactly what it is meant for.Let a switch be a switch and let a router be a router.Unless the the OEM has that option available by integration or hardware/systems growth.This way you will be sure that the generic will not have issues,
the peripherals will not have issues,
all processes execute as normal. when the OEM goes to his next customer you are left to
manage what you built.
