R37.5 – Proxy Point Code
Network management and test messages sent to GMSC A (111) will have the PPC as OPC (222)
All Network management and network test (SI=0, 1, and 2) messages from the Adjacent Node of a Proxy Linkset, with a DPC of the Proxy Point Code shall be processed by the EAGLE 5 ISS as if the DPC was the EAGLE 5 ISS
All other messages from the Adjacent Node of a Proxy Linkset shall be handled as the STP normally processes MSUs (e.g.: routed to the DPC)
