Time division switching is done between traditional network ports (extensions, relays, etc.), and IP terminals (Dterm IP, IP soft phone) or IP-based CCIS connections with traditional time division ports (extensions) can be connected through various methods, such as CCIS-based connections. Based on H.323 protocol connection method.
