Information technology. Telecommunications and information exchange between systems. Broadband private integrated services network. Inter-exchange signalling protocol. Transit counter additional network feature Ingestion-build-63436 f) Methods for mitigating operational1 Scope This International Standard specifies the signalling protocol for the support of the Transit Counter additional network feature (ANF TC) at the Q reference point between Private Integrated Services Network Exchanges (PINXs) connected together within a Broadband Private Integrated Services Network (B PISN). ANF TC is a feature that limits the number of Transit PINXs that a call connection setup request may be routed through e. g., to protect
