Synchronization clocks for GSM mobile networks
In 2G/GSM networks, just as in most other network types, interconnected network elements interwork correctly only if the signals they exchange comply with given synchronization quality requirements. The synchronization quality of the signals is determined by the network elements’ equipment clocks.
Equipment clocks control some of the important signal processing functions within the network element (e.g. multiplexing, switching), as well as the data rate (accuracy, stability) of outgoing traffic signals. There are different clock frequency accuracy and stability requirements for different network element types.
In most cases frequency accuracy specifications are much tighter than what the equipment clock could deliver if it were free running. This means that most equipment clocks need to be synchronized or “locked” to an external and possibly remote high accuracy frequency reference clock.
OSA 5420 Series
Our OSA 5420 series is a family of cost-effective, mid-scale synchronization distribution and assurance devices that bring the power of Syncjack™ to any network. Following a toolbox approach, the family members of the OSA 5420 series can be utilized in a variety of network synchronization applications, including IEEE 1588v2 Grandmaster, Boundary Clock, Slave Clock and Assisted Partial Timing Support (APTS).
OSA 5335 PTP Grandmaster
Our OSA 5335 Modular PTP Grandmaster is a scalable and high-performance IEEE 1588v2 standard compliant Grandmaster Clock for the distribution of frequency, phase and time synchronization over packet-based network infrastructure including IP/MPLS, Carrier Ethernet, PON and DSL networks.
OSA 5548C SSU
Our OSA 5548C Synchronization Supply Unit is a scalable synchronization solution rangingfrom 20 unprotected outputs up to 1,000 protected outputs by adding up to four expansion shelves to the core unit. Its ultra-compact footprint makes it ideal for telecom operators to provide scalable network synchronization in over-crowded exchanges.
OSA 3230B Cesium Clock
The Oscilloquartz’s OSA 3230B Cesium Clock is specifically designed and produced with the latest technology to serve complex applications where an extremely accurate reference signal is needed in a minimum size.
SyncView™Plus is a comprehensive synchronization Management System that allows telecom operators to manage all Oscilloquartz synchronization elements from a single local RS-232 serial connection to one shelf up to hundreds of units from a single point via remote Ethernet connection.
