  • System for switching and safeguarding data in time-division multiplex switching networks
    Patent number: 3984641
    Abstract: A system is disclosed for safeguarding data against slip in signals occurring in interfaces between exchanges employing different exchange clock rates. Suitably connected storage arrangements cause the instants of slip compensation in both directions of transmission to coincide. In this way, omission of a signal in one direction of transmission results in a signal being inserted in the other direction and prevents the loss of data.
