Alcatel-Lucent and Symmetricom have closely collaborated to perform detailed interoperability testing with the scope of validating the transport of 1588 frames over microwave networks leveraging Symmetricom's carrier-class TimeProvider® 5000 1588 Grandmaster and TimeProvider® 500 IEEE1588 Translator.
Tests were intended to validate the tunneling transport of 1588v2 frames across a microwave network as guaranteed traffic for frequency recovery. This way 1588v2 performance is guaranteed and respects the typical synchronization mask of 16 ppb. In all cases the recovered clock has a Fractional Frequency Offset in the range of ±2ppb. This value meets the frequency accuracy of 16ppb required by mobile access applications for frequency synchronization purposes.
Tunneling is a feature of the Alcatel-Lucent 9500 Microwave Packet Radio (MPR), the first packet microware platform launched on the market. The tunneling is based on the established and patented fragmentation and interleaving techniques used by 9500 MPR over the microwave links. These mechanisms provide a deterministic delay and, most important for the handling of 1588v2 packets, packet delay variation even in heavy congestion conditions. This is extremely important with 1588v2 slaves that need to have consistent network delay of 1588v2 frames to derive their synchronization.
