Multiple SAPs may be defined on the same physical port and may be used for different services.
Multiple Service Access Points (SAPs) can indeed be defined on the same physical port and used for different services. This is because a single physical port can handle various types of data streams and service definitions, each corresponding to a different SAP.
"Depending on the encapsulation, a physical port or channel can have more than one SAP associated with it. SAPs can only be created on ports or channels designated as “access” in the physical port configuration. SAPs cannot be created on ports designated as core-facing “network” ports as these ports have a different set of features enabled in software." https://documentation.nokia.com/html/0_add-h-f/93-0076-10-01/7750_SR_OS_Services_Guide/services.html
