PulsePkt3bPulse packet register signaling using R1 frequencies with 50msec on/off periods. The packet that contains call category (signal number 13), called number and packet terminator (signal number 11) is sent in one package, after the request from the upper exchange. The correct reception of the packet is confirmed by the upper exchange. Since the called number is sent in a package with predefined timing periods, to route out a call from Pulse Pkt3b E1, accumulation of digits before routing is required. |
