Abstract
The Asynchronous Packet Manager is the interface for transferring data in a first format between a data terminal equipment and a combination data and telephone switching system in a properietary packet format. A microprocessor accepts data from a universal asynchronous receiver transmitter and forwards the data to a mini packet receiver transmitter, when it is formatted into mini packets and converted to an alternate mark inversion signal and sent to the switching network.
Claims1
In a telecommunication switching network for interconnecting data units arranged to transmit data in a first format to a switching unit arranged to switch data of a second format;
- a universal asynchronous receiver transmitter module (UART);
- an interface operated to convert incoming data to TTL levels and connected to said UART;
- a parallel data bus;
- said UART operated to convert received serial data into a parallel form and place it on said data bus;
- a microprocessor connected to said parallel data bus;
- a minipacket receiver transmitter connected to said microprocessor and to said parallel data bus;
- said microprocessor operated upon data presented on said parallel data bus to control said minipacket receiver transmitter to accept said data;
- said minipacket receiver transmitter operated upon receipt of said data to format said data into minipackets and convert said formatted data to an alternate mark inversion signal for connection to a switching network.
