The Master PTP 600 automatically controls the structure of the TDD Frame, optimizing
Burst Duration and Frame Duration for either maximum capacity or minimum latency
depending on the setting of Link Mode Optimization and Link Symmetry.
When TDD synchronization is enabled (see
TDD synchronization configuration
on page
), the user must configure the TDD Frame which includes configuration of Burst
Duration and Frame Duration.
Link mode optimization
Link mode optimization allows the PTP 600 link to be optimized according to the type
of traffic that will be bridged. The link supports two modes, IP Traffic and TDM Traffic.
IP traffic
IP Traffic mode is optimized to provide the maximum possible link capacity. IP Traffic
mode is an appropriate choice where applications in the bridged networks provide
some measure of reliable transmission, and where very low latency is not critical. IP
mode supports both fixed and adaptive link symmetry (see
