<p>With respect to an A-interface (26, 28) within a cellular network (10), the flow of operation and maintenance information between network layer end-points (108) of the network in connection with A-interface signaling transmissions (DS0 or AAL) over the A1 and A4 sub-interfaces is carried by an F6 OAM flow. Similarly, the flow of operation and maintenance information between network layer end-points of the network in connection with A-interface traffic transmissions (DS0 or AAL) over the A2 and A3 sub-interface is carried by an F7 OAM flow.</p> |
