Telecom Primary Reference Sources
The highest level of time and frequency accuracy throughout the network
All clocks in a synchronization network must be referenced, or traceable, to a Primary Reference Source. Symmetricom’s GPS Primary Reference Sources (PRSs), also known as "master clocks," provide the highest level of time and/or frequency accuracy for telecom networking as required by international standards. Our wide variety of PRSs are categorized by the source that is used to derive their timing outputs: GPS (Global Positioning System), Cesium (atomic clock), or Packet PRS (IEEE 1588 PTP). Advances in IEEE 1588 Precision Time Protocol, GPS and atomic clock technologies have made providing precision time and frequency within the network more widely available, which assures the highest level of time and frequency accuracy throughout the network.
TimeSource 3500 is a stand alone Primary Reference Source (PRS) that meets GR 2830 network PRS performance requirements by using a GPS antenna mounted inside a window or on an outside wall. It provides Stratum 1 performance in GPS hostile environments, such as through windows, walls or roofs.
Like the TimeSource 3500, the TimeSource® 3600 is a standalone Primary Reference Source (PRS) which provides Stratum 1 performance in GPS hostile environments, such as through windows, walls or roofs. It meets ITU-T G-811 network PRS performance requirements inside a building using an antenna mounted inside a window or on an outside wall.
TimeProvider 1000 meets the need for high quality synchronization beyond the network core and into metro and access offices. Its innovative architecture combines the tasks of tracking incoming timing references, qualifying the signals, filtering and distributing precise synchronization onto a single universal Input, Output and Clock card (IOC).
TimeProvider® 1500 is a carrier-class Packet PRS system that enables easy migration to packet-based networks. Powered by a Symmetricom Rubidium Miniature Atomic clock, TimeProvider 1500 has the ability to synchronize to another non co-located grandmaster clock over packet-based networks.
