TimeProvider 2x00

TimeProvider 2×00 – Symmetricom's Edge Master Clocks are advanced IEEE 1588 Precision Time Protocol (PTP) products that are scaled and optimized for deployment at or near the mobile network edge—solutions that evolve the synchronization distribution architecture without retrofit of existing backhaul equipment or reengineering the network.

TimeProvider 500

The TimeProvider 500 is a standalone Precision Time Protocol (PTP) client that enables network service providers to accelerate the upgrade of their existing network infrastructure to accommodate the next-generation, packet-based timing and synchronization solutions. As a standalone device, TP 500 enables seemless migration of wireless base stations, DSLAM's, LTE equipment and other end-point network devices to PTP, providing immediate cost savings and a quick return on investment.

TimeSource 3x00

TimeSource 3×00 provides your network Stratum 1 performance when locked to GPS or up to 72 hours if GPS signals are interrupted.

TimeSource 3×00 is a standalone office Primary Reference Source (PRS) with an integrated GPS receiver that allows your network to meet GR2830 requirements.


The DCD-LPR is a front-end primary reference source used in conjunction with the DCD bits clock platform for synchronizing digital telecommunications networks. The entire DCD timing platform is still a very widely utilized system and due to tight current-day budgets many of these clocks are expected to serve into the foreseeable future. Syncworks has the legacy clocking experience and surplus of parts needed to keep your system running as long as possible.

DCD-523 / DCD-400

Originally produced by Telecom Solutions, the DCD line of BITS clocks is one of the most widely used and recognizable clocks in North America. The DCD clocks serve as a common source for the frequency and phase sync necessary in any digital network element, tramission or switching. The DCD line of clocks is also known for its reliability. The DCD clock provides the necessary bridge in timing (holdover) and allows the network to continue to operate slip-free for several hours or days depending on the clock.

The DCD clocks were also designed to facilitate modular growth. DCD systems can be as simple as one master shelf. Up to three expansion shelves can be added to the master shelf, and output slots may be equipped as needed.


Originally produced by Austron, which then became Datum. the PRR-10 was and continues to be a widely deployed Primary Reference Source for digital switches. The Datun Sync Equipment PRR-10 is designed to provide highly reliable Stratum 1 synchronization signals.


The TSG-3800 family of Timing Signal Generators was originally manufactured by DATUM and is made up of a 3800 master shelf and accompanying expansion shelf. They are timing signal generators that generate and distribute network synchronization signals. Input signals can be DS1, E1, 2048 kHZ, sinsoids, or square waves.

Symmetricom’s high-performance SyncServer S200 is an enterprise class GPS Network Time Server that supports the expanding technological requirements of large enterprises It protects the integrity of IT network accuracy, billing systems, electronic transactions, database integrity, VoIP quality, and other essential applications.

SyncServer S250

Next Generation ready, the SyncServer S250 is a GPS Network Time Server with multiple and versatile timing configurations. It provides ultra precise time and frequency outputs and redundant back-up, essential for Next Generation IT networks that require network time servers that are versatile in their ability to provide precise time.

SyncServer S300

Faster, more accurate, more secure, increased redundancy, and maximum reliability – these features all contribute to higher levels of performance and assure optimal integrity within the Next Generation IT network.

SyncServer S350

Versatile network time servers are often needed to meet the requirements for demanding, high performance network time synchronization as well as supply traditional time and frequency technology. The SyncServer S350 provides unsurpassed NTP performance for the IT network while being the most versatile time server in the world for traditional time and frequency applications.

SSU 2000 PTP and NTP Blades Upgrade Kits

The Symmetricom IEEE 1588 Blades are fully integrated into the SSU 2000 system. These Cards can be installed as single servers or redundant pairs in any available master or expansion shelf output slot. PTP capacity scales up at a rate of up to 400 full rate clients per card. Front-access IEEE 1588 traffic ports utilize Small Form-factor Pluggable (SFP) modules for flexibility to support 100 Base-T electrical or 1000Base-X optical or electrical interfaces. All configuration and management is consolidated through SSU 2000 system management ports to maintain security and isolation from IEEE 1588 ports.

TimeHub 5500 NTP Upgrade Kit

Symmetricom’s NTP blades for the TimeHub 5500 allow your networks to meet modern critical requirements for the delivery of advanced services such as IPTV Content and Delivery, Billing Record Management, IP SLA Monitoring, and QoS Measurement Systems/Probes. With the introduction of high performance NTP servers on a card, the BITS platform can now deliver carrier-class NTP to meet demanding NGN Packetime requirements. The product also features additional security in the form of dual NTP ports found on the Timehub blades. Timehub’s NTP Server cards provide the performance, scale, availability and security to assure high QoS delivery of advanced services such as IPTV.
