| Abstract: | The solution method for the signaling link by using the technologies of channel associated signaling for ultra-short wave radio is proposed.We study the transmission of signaling signal with the compelled method of multi-frequency,and study the switching control of DTMF signaling with exchange in wireless in details.The software for the signaling calling processing in the exchange side and telephone side under the connecting way of channel associated signaling is designed,and also the hardware interface circuit for the exchange and telephone set.The concrete resolving method is given in this paper at the same time. |
