Hybrid type telephony system
First Claim
1. A hybrid telephony system comprising:
- a first switch to perform time division switching of signals;
a second switch to switch packets from a source to a destination;
a gateway to convert signals to packets and forward the packets to the second switch, and convert packets from the second switch to signals and forward the signals to the first switch; and
a control unit to control the first switch, the second switch, and the gateway via a control bus, the control unit connecting directly to the first switch, the second switch, and the gateway via the control bus.
