T1 Over IP, T1 Over Ethernet, Data and Voice Over IP, IPTUBE

Applications

The PrimaStratum receives GPS satellite timing signals to control an onboard oscillator providing from one to 4 T1 or E1 Stratum 1 reference clocks. The PrimaStratum utilizes a mixed-signal phase lock loop GPS driven frequency module to generate extremely accurate 1.544MHz/T1 and/or 2.048MHz/E1 references clocks that are frequency locked to the Global Stratum 1 source. The Stratum 1 clock is the basis for all telecom voice and data interfaces, required to assure proper synchronization of signals and call quality.

Stratum 1 Timing for Cellular Backhaul

Base Station Conversion
As Base Stations are upgraded to 3G and 4G networks, the networks supporting such stations are also upgraded to IP based connections. The system incorporates both synchronous and asynchronous interfaces. The issues are seen at the remote base station, telcom timing is lost over the IP network and often a more reliable clocking source will be needed to maintain call quality and connections. The PrimaStratum can be added to the far-end base station to provide this clocking signal.

GPS Clocking

Mobile Service Drop-off
Mobile Carrier Service Drop-Off Mobile systems require extremely accurate clock sources at often very remote locations. Add to this fact that at these locations several carriers might be sharing base station equipment and separate TDM circuits need to be accessed per carrier. Without a local source of Stratum 1 timing, these circuit drop-offs can be a significant source of issues. The PrimaStratum provides a source of Stratum 1 timing at even these remote locations to assure that all carrier circuits are timed correctly and drop-off is with a minimum of problems.

Built-in Ethernet Switch
A four (4) port Ethernet switch is an option available on the PrimaStratum. The Ethernet switch functionality is a major plus to mobile operators as they move to upgrade their existing circuits to 3G and 4G services. A rate limiting capability built into the switch means that available bandwidth can be allocated to T1 or E1 circuits for voice backhaul or can be reserved as 3G and 4G data usage increases.
