39、ork (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 the network against indefinite looping.The Q reference point is defined in ISO/IEC 11579-1.Service specifications are produced in three stages and accor

ThisInternational Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified bythe stage 1 and stage 2 specifications in ISO/IEC 15055.The signalling protocol for ANF-TC operates in association wit
