I have an ericsson RNC with two TMs of STM configured for ATM ports(in IMA mode) towards SGSN .
i can see the port status as enabled for both the atm ports.. the person at SGSN says that one of my TM/ATM port is down,and i cannot see it here.
How can I be certain that the ATM ports are working or not ? I am new to RNC , will anyone help please..
thanks in advance
