It is mainly used for the interconnection between cluster communication system and conventional communication system. With the help of conventional communication, the coverage of the cluster system is extended effectively, and it is a cost-effective extension coverage solution for cluster base stations. It uses intelligent controller to connect the link machine of the cluster system with the conventional transposon, and realizes the inter-sound communication between the conventional terminal and the cluster terminal. Multiple HYT intelligent general transfer station (can be different frequency bands) through a cluster base station can achieve interconnection, these intelligent general transfer station cluster link machine into the same group, the cluster terminal through the call group number of this group can call these intelligent regular transfer station within the regular users. HYT intelligent conventional transfer station adopts the company's newly developed high-performance TM-800M cluster vehicle as a cluster link machine, and uses high-performance QHB-2920-BS channel machine as a regular channel machine, the performance is stable.
