TimeProvider 4100 is a 1588 grandmaster that includes support for the latest ITU-T G.8275.1 and G.8275.2 1588 phase profiles, complemented by extensive port deployment for PTP, Network Time Protocol (NTP), SyncE, and E1/T1. Software version 2.1 builds upon previous versions by adding key software enhancements that provide a virtual primary reference time clock (vPRTC). The virtual PRTC enables the design of a precise and redundant time distribution architecture for phase protection in an optical network.
Until recently, the primary source of accurate time has been the Global Positioning System (GPS) and the regional constellations comprising GNSS. However, GNSS deployment can be costly for service providers given the expenses associated with upgrading to GNSS-capable receivers and antennas, as well as the increased density of endpoints. As a result, telecom, cable, and utility operators implementing vPRTC benefit from solutions that reduce or eliminate reliance on GNSS.
The following are key features of the new vPRTC functionality:
• Leverages the existing optical network, avoiding high-cost dark fiber.
• Uses a dedicated lambda signal to accurately and securely transport time.
• Provides a high-performance redundant time source via enhanced PRTC (ITU-T G.8272.1).
• Enables accurate, bidirectional (east and west) time streams.
• Chains together high-precision, multi-domain, high-performance boundary clocks that comply with current standards (T-BC Class D, as defined in ITU-T G.8273.2).
Microchip's vPRTC multidomain architecture is a cost-effective solution that provides redundant, high-performance, sub-5 nanosecond time-accurate distribution across regional and national networks.
Furthermore, version 2.1 introduces the Network Time Protocol Daemon (NTPd) with the Message Digest (MD5) security algorithm.
TimeProvider4100 2.1 meets PRTC-B performance standards (according to ITU-T G.8272) and supports 1G and 10G, NTP and PTP in a single form factor system. TimeProvider 4100 2.1 is now available for both new and existing systems.
