N2 - This paper presents a telecom circuit-emulation system that uses the Precision Time Protocol (PTP) aka IEEE1588 v2 for frequency distribution. In particular, a differential clock recovery mechanism is described that uses PTP as its reference clock based at one time on OCXO and at the other time on TCXO. A performance comparison is demonstrated for various test scenarios and compared against the stability requirements for CES clock per ITU-T G.8261 and against the stricter requirements for TDM synchronization distribution per ITU-T G.823 and SDH Equipment Clock (SEC) requirements per ITU-T G.823. The new obtained test results may indicate whether a PTP slave clock based on TCXO can be used in a telecom circuit-emulation system and lead to a more cost effective solution compared with traditional adaptive clock recovery methods.
