| 摘要 | A network node of a synchronous network, wherein said network node comprises a timing circuit which recovers a reference clock from a reception signal received by said network node from an upstream network node of said synchronous network and uses the recovered reference clock for a transmission signal transmitted by said network node to a downstream network node of said synchronous network; and a clock stability monitoring circuit which monitors internal control parameters (CP) of said timing circuit to detect an instability of the reference clock distributed within said synchronous network. | ||

| 主权项 | 1. A network node of a synchronous network, comprising: a timing circuit, which recovers a reference clock from a reception signal received by said network node from an upstream network node of said synchronous network and uses the recovered reference clock for a transmission signal transmitted by said network node to a downstream network node of said synchronous network; and a clock stability monitoring circuit which monitors internal control parameters of said timing circuit to detect an instability of the reference clock distributed within said synchronous network, wherein the timing circuit comprises a register in which dummy data is written with a reception clock rate and from which said dummy data is read with a transmission clock rate to detect said instability of the distributed reference clock. | ||
