Hybrid type telephony system
First Claim
1. A hybrid type telephony system capable of establishing a connection between conventional type telephone sets contained in an exchange unit and LAN type telephone sets contained in an IP network, the system comprising:
- a gateway circuit connected between the exchange unit and the IP network and performing voice data format conversion,a central control unit connected to a LAN of the IP network for establishing a communication path to the exchange unit via a control bus, controlling switching of IP packets of the IP network, managing IP address information of the LAN type telephone sets and the gateway circuit via the LAN, and controlling connection between the LAN type telephone sets and connection between the LAN type telephone sets and the gateway circuit, andwherein the control bus forms a communications path for enabling the central control unit to control a time-division switch for the conventional type telephone sets and an IP switch for the LAN type telephone sets.
