Abstract

Purpose of the present document Many types of equipment in the telecommunication network need a synchronization reference signal with a certain degree of quality in order to operate satisfactorily. The purpose of the synchronization network is to deliver to each of these equipment such a synchronization signal in a reliable and efficient manner. The present document gives guidance on the manner in which the involved rules, specifications and principles, as laid out in various ETSI and ITU documents, can be applied to practical networks, both new and existing: it provides guidelines in planning, implementing and maintaining the Synchronization Network in an efficient manner. Relationship with other Documents Today, there are no standardization documents describing the architecture of the synchronization network other than a number of documents describing the need of certain traffic networks for synchronization. There are also a large number of documents describing the individual network element requirements on synchronization. As examples: Synchronization Interface Networks limits are described in EN 300 462-3 [3], Synchronization requirements of network clocks are described in EN 300 462-4-1 [4], 5-1 and 6-1. Jitter and Wander requirements of traffic interfaces including those carrying synchronization are described in EN 302 082 [11].
