Synchronization solution for the aggregation of LTE services in ETECSA's network

Abstract

The present investigation deals with the current evolution of the aggregation systems based on Ethernet Switch and how this should evolve into systems with synchronous support. This work does not try specifcally on the technologies LTE, is about adaptations required in the network of an Operator for the support of services that require synchronous functions. Although the synchronous functions is a topic highly treated in literature, it is considered of great importance due to the fact that its domain for engineers and specialists is closely bundle to the transmission nets supported with SDH technologies.
