Carrier grade, packet-based timing and synchronization

The TimeProvider® 5000 PTP Grandmaster offers a software option to add carrier grade NTP server capability, enabling communications service providers to simultaneously support both PTP and NTP elements in the network.

Product Information

Product Information

TimeProvider® 5000 Grandmaster is a Precision Time Protocol (PTP) timing source that enables communications service providers to build a more stable, robust and reliable network infrastructure. An NTP software option and expansion shelf capabilities that include Synchronous Ethernet and an advanced PTP profile make this timing and synchronization system capable of supporting network needs today and in the future. A carrier grade design with flexible capabilities is vital to enable circuit to packet network migration for high-speed data services and wireless backhaul, and to deliver 3G, 4G/LTE and advanced LTE wireless, as well as broadband multimedia to the network edge and customer premise.

High performance for carrier grade applications

TimeProvider 5000 combines the functionality of a highly-accurate IEEE 1588 grandmaster clock with E1 or T1 and 10MHz/1pps I/O ports in a high-performance, yet highly compact 1RU footprint. TimeProvider 5000 adheres to the latest IEEE 1588-2008 (PTP v2) standard including the provisioning of telecom profile extensions for telecommunications based applications.

Fully redundant equipment, high network availability


With dual Input/Output Clock cards in active and standby mode, TimeProvider 5000 ensures there is no impact on client performance when failover occurs. Redundant cards provide protection far superior to “network redundancy” models that must re-acquire synchronization from a different grandmaster somewhere else in the network. Modular construction yields a lower mean-time-to-repair than sealed, self-contained units.

High client capacity, high message rate

TimeProvider 5000, with hardware-based time stamping and packet processing, delivers high client capacity at full rates: up to 1000 clients at up to 128 messages per second. A performance level that does not degrade as the number of clients increases.

Improved QoS and packet-based network performance

The TimeProvider 5000 is designed from the ground up to handle the most stringent timing requirements of today’s emerging packet-based, next generation networks. The TimeProvider 5000 enables service providers to roll out feature-rich, lower-cost, packet-based services without sacrificing timing accuracy or quality of service.

Optional quartz and rubidium oscillators

TimeProvider 5000 is available with both quartz and rubidium oscillator options enabling service providers and network equipment manufacturers to choose the optimal level of holdover based on network performance, applications requirements and equipment cost targets.

NTP server option

The TimeProvider 5000 PTP Grandmaster offers a software option to add carrier grade, hardware-based NTP server capability, enabling network providers to simultaneously support both PTP and NTP elements in the network. The NTP server capability can support up to 20,000 transactions per second.

TimeProvider Expansion capabilities

TimeProvider 5000 Grandmaster serves as the initial unit in a “rack and stack” configuration with TimeProvider Expansion products. These 1 RU shelves greatly expand the capabilities of the TimeProvider portfolio, and up to ten expansion shelves can be deployed in any combination. With two high-precision DTI ports for inter-shelf connections and redundant power connections, the expansion units deliver the carrier grade protection needed to ensure service availability and network uptime.

TimeProvider Expansion 10

The TimeProvider Expansion10 shelf adds up to 16 Ethernet ports that simultaneously support PTP and SyncE. The PTP profile is aligned with the developing ITU standard for time and phase. With SyncE to frequency synchronize the transport network and PTP for time and phase to base stations, the TimeProvider Expansion 10 is a complete solution for mobile networks as they evolve to technologies such as LTE-TDD (time division duplex) and LTE-Advanced.

The TimeProvider Expansion10 uses hardware-based time stamping and packet processing to support up to 400,000 PTP multicast clients. The SyncE implementation includes support for the Ethernet Synchronization Message Channel (ESMC).

TimeProvider Expansion 30

Even as networks transition the requirement remains to synchronize elements using the frequency and interfaces of the traditional TDM network. The TimeProvider Expansion30 has 12 E1/2.048MHz output ports and 12 1PPS/TOD output ports—allowing carriers to provide synchronization for all of their equipment from one TimeProvider stacked configuration.
