Transit Counter, QSIG-TC (ISO/IEC 15055/15056)
Scope
This Standard specifies the signaling protocol for the support of the Transit Counter additional network feature (ANF-TC) at the Q reference point between Private Integrated Services Network Exchanges (PINXes) connected together within a Private Integrated Services Network (PISN).
ANF-TC is a feature that limits the number of Transit PINXs that a call setup request may be routed through e.g., to protect the network against indefinite looping.
