Hi,
When a MTP3 restart is over, SCCP sends a N-PCSTATE, N-STATE primitives
informing "signaling point accessible", "remote SCCP accessible" and
"users in service for subsystem". SUA at SG receives these primitives
via NIF(nodal interworking function) and sends DAVA/DRST messages to
concerned ASPs.
What happens at SUA, when a SG discovers SS7 network isolation, when a
MTP3 restart begins? Does SUA receive a N-PCSTATE(pointcode
inaccessible), N-STATE(UOS) primitive. How does SUA know when to send a
DUNA message.
What primitives are exchanged between MTP3, SCCP, NIF and SUA when MTP3
restart begins.
