Abstract
A method for synchronizing code machines, operated within a block network, provides that a connection completion block be transmitted and a connection confirmation block be received and stored by a code machine, after which the code machines are phased in. The transmitting code machine then causes transmission of the connection confirmation block to its own data terminal equipment. After transmission of the last data block, a connection release block is recognized by the code machine and the machines are phased out.
Claims4
In a method of synchronizing first and second code machines which are operated in a packet switching network, in which a set up block is transmitted to set up a connection between a first data terminal equipment and a second data terminal equipment, a connection confirmation block is transmitted between the second data terminal equipment and the first data terminal equipment, and then the data terminal equipments then transmit data blocks to one another, the improvement therein comprising the steps of:
- storing the connection confirmation block in the first code machine of the first data terminal equipment;
- after receiving the connection confirmation block, transmitting a code machine synchronization block from one code machine to the other to synchronize code computers in the code machines;
- and
- after synchronization of the code computers, relaying the connection confirmation block to the first data terminal equipment.
