It Support today 4G and ready for 2G and 3G backhaul. Assuring consistent level of service across the network requires monitoring of both the end-to-end and segment QoS with notification of any degradation in circuit quality (delay, jitter) to the cellular operator. Ethernet OAM (according to IEEE 802.3ah/IEEE 802.1ag/ITU-T Y.1731) helps monitor each service in terms of availability, frame loss and delay. In addition for each service thresholds can be defined alarming when the service deviates the SLA.
