EINMESSUNG VON TDMA-SYSTEMEN MIT EINEM PASSIVEN OPTISCHEN NETZWERK

摘要

The calibration system uses an initial calibration time slot with a duration which is longer than that of the calibration time slots used during operation of the system. Before the initial calibration the data flow from the central unit (OLT) to the exchange is reduced with temporary storage of the untransmitted data, for transmission during the initial calibration. The data received at the peripheral for transmission to the central unit is stored during the initial calibration and transmitted at a slightly increased data rate after the latter. Pref. the initial calibration time slot has at least double the duration of the successive calibration time slots.
