APSIMP

How do you clear this alarm whe the connecting node is a Fujitsu FLM150 setup up in terminal mode? I have a 1+1 port group setup on the Cisco OC3. The Fujitsu end is not in my control, but will switch traffic if a fiber is opened.

The APS Invalid Code alarm occurs if a 1+1 protection group is not properly configured at both nodes to send or receive the correct APS byte.A node that is either configured for no protection or is configured for UPSR or BLSR protection does not send

the right K2 APS byte anticipated by a system configured for 1+1 protection. The 1+1 protect port monitors the incoming K2 APS byte and raises this alarm if it does not receive the byte.It clears when the port receives a valid code for 10 ms.

I think this alarm can also be raised if working on one side is connected to protect on other side. you may want to check that.
