Based on the precision time protocol (PTP) IEEE 1588 v2 standard, time and frequency solutions provider Symmetricom, Inc. has readied an access timing device, labeled TimeProvider 500. The TimeProvider 500 translator enables existing wireless base stations (GSM / UMTS) to use next generation IP based backhaul (such as Gigabit Ethernet), and not be tied to T1/E1 lines for their synchronization needs. It delivers cost-effective and reliable frequency synchronization. To help telecommunications service providers and mobile operators maximize their return on investment and minimize service disruptions when deploying packet-based mobile backhaul networks, Symmetricom has also released a comprehensive set of resource materials.

According to Symmetricom, the TimeProvider 500 is a PTP 'client in a box,' which allows operators to smoothly and simply transition to next generation Ethernet without disrupting network synchronization at the base station. It translates 1588 timing packets to a stable T1/E1 output for timing at the base station. With PTP IEEE 1588 v2, different end devices in an Ethernet network can be synchronized, allowing operators to distribute precise time and frequency throughout the network in order to maintain and assure service levels supported by traditional TDM networks. The TimeProvider 500 translator system has two T1/E1 outputs to synchronize equipment in wireless base stations, street cabinets and remote terminals.

Symmetricom said that the TimeProvider 500 is expected to be available in the third quarter. The company will be demonstrating the system at NXTcomm 2008, June 16-19 in Las Vegas, NV.
