The Springwave’s IS2000 series is a grandmaster clock to build the precision time and frequency synchronization based on the IEEE 1588v2-2008 standard. Especially, it is designed for the economic deployment and precision synchronization in the 4G/LTE small cell networks which mobile data service traffic is growing at the present day. Also it supports Synchronous Ethernet clock master synchronized with the GNSS reference in the carrier ethernet networks. |
IS2000 Edge Master in the Small Cell Network
Currently the base stations in the 4G/LTE small cell networks are increasing caused by the tremendous mobile data traffic growth, like smartphone. Furthermore, these base stations are demanded on the precision time/frequency synchronization, and the equipment is increasing coming from their narrow RF coverage.
The IS2000 series is designed to solve these two issues in the small cell networks. The one is deployment price, and other is synchronization accuracy. |
Feature Highlights
Alternate Master for Protection | Hybrid operation | Mixed-mode PTP communication |
The carrier-grade networks may be needed protection clock for reliable network operation. The alternate Master based on BMCA (Best Master Clock Algorithm) specified in IEEE1588v2-2008 supports the master equipment protection and the network protection. The slaves selects the grandmaster on the basis of QL value first, then priority. IS2000 series following G.8275.1 and G.8265.1 profiles is completely designed for these protection. | Synchronous Ethernet is a physical layer–based technology, supports hop-by-hop frequency transfer, where all interfaces on the trail must support Synchronous Ethernet. In the hybrid mode, the frequency syntonization derives from physical layer of synchronous ethernet, and phase and time of day derives from PTP. These technic may resolve a large number of network hops and provide clock synchronization accuracy. IS2000 series supports this hybrid-mode operation by configuration. |
Basically ITU-T G.8265.1 recommends unicast PTP communication for telecom networks. Optionally, it can be operated mixed-mode PTP communication to reduce the network traffic load. This mixed-mode is multicast downstream(Sync, Announce), and unicast(Del_Req, Del_Res) traffic mixed. IS2000 series supports below operation modes. - Unicast mode |
