DS3 TO 28 VT1.5 SONET INTERFACE CIRCUIT

摘要

Title of the Invention: DS-3 to 28 VTl.5 SONET INTERFACE CIRCUIT Inventors: THOMAS E. MOORE A DS-3 to 28 VTl.5 SONET Interface Circuit is shown, without using standard intermediate DS-2 and DS-1 Synchronizer Phase Lock Loops. The elimination of DS-2 and DS-1 Synchronizer Phase Lock Loops results in a significant reduction in cost and complexity of SONET interface circuits for the existing asynchronous digital multiplex hierarchy.
