SUMMARY
Layer Function
Defines the physical and electrical
MTP-1
characteristics of the signaling link
Provide reliability transfer of signaling
messages (CCS) between source
MTP-2
and the destination signaling node via
a signaling link
Provide functionalities for routing of
signaling messages between signaling
MTP-3
nodes. The routing was performed by
the STP signal nodes.
Performs basic telephone call connect
