Huawei announced a 1588v2-compliant DSL prototype with nanosecond-level time synchronization accuracy. This could support the Ethernet synchronization requirements in mobile backhaul applications for 3G/4G networks.
Huawei said its prototype leverages its proprietary high-accuracy time synchronization algorithm and complies with the IEEE 1588v2 standard.
1588v2, also known as Precision Time Protocol (PTP), is a packet-based time synchronization technology standardized by the IEEE. The 1588v2 time synchronization algorithm is originally designed on the basis of symmetric models, and asymmetric transmission technologies such as ADSL cannot effectively support the 1588v2 protocol.
“DSL remains the world’s most widely used broadband access technology. Technical breakthroughs such as this one will enable operators optimally utilize their abundant copper wire resources, as well as achieve quick provisioning of their 3G/4G services. The leading xDSL time synchronization prototype reflects Huawei’ s commitment to deliver a powerful and unique value proposition to its customer,” stated Yang Zhirong, president of Huawei’s Access Network Product Line.
