Simulation of the embedded operations channel for ISDN basic access

摘要

A description is given of computer simulation and a mathematical model of the embedded operations channel (EOC) protocol which evaluates protocol performance. The simulated EOC acknowledgement times match the theoretical model to within 0.4% for bit error rates (BER) between 10/sup -8/ and 10/sup -3/. The simulation results show that the EOC performs with negligible degradation during valid digital subscriber line (DSL) service (BER>10/sup -3/). It falls within the 100 ms EOC maximum time target during DSL outages (BER approximately 10/sup -2/).
