ABSTRACT:
A multiple channel transit call control apparatus includes a transit message storage queue unit, a node message counter, a node transit trunk call opportunity message definition count memory, and a control unit. The transit message storage queue unit stores transit messages arriving at a storage and forward switching system according to destination node identity. The node message counter counts messages in the transit message storage queue unit according to destination node identity. The node transit trunk call opportunity message definition count memory defines the number of channels to be called for every predetermined count of the node message counter according to destination node identity. The control unit outputs a call request signal when the value of the node message counter exceeds a predetermined count stored in the node transit trunk: call opportunity message definition count memory.
