Mobile operators are deploying small cells to build out their LTE and 5G networks. This is occurring in a variety of locations such as in urban canyons and indoors, where GNSS signals are weak or intermittent. TesCom's Ts2, a multi-sync gateway addresses the challenges of providing reliable and precise synchronization everywhere through IEEE 1588-2008 (PTP) and leveraging multiple sync references.
Ts2 is designed for deployment in distributed clustered architectures. In such deployments, timing resources are deployed close to the edge of the network in order to meet the phase and frequency precision requirements at the small cell or remotedistributed or radio units (DU / RU). Deploying a centralized Grand Master with full onpath support to deliver high precision sync imposes a significantly higher cost. Next-generation networks require a more decentralized approach. The Assisted Partial Timing Support (APTS) architecture is designed for these networks to deliver precise phase and frequency to small cells in a scalable and cost-effective manner. Ts2 is highly field-scalable and designed for such edge oriented distributed architectures.
Ts2 provides IEEE 1588-2008 (PTP) Grand Master and Boundary Clock functionality at a low total cost of ownership. It leverages TesCom's unique industry-leading PTP algorithms to deliver stringent timing for LTE-A, LTE-TDD, CBRS (USA), SxGP (Japan), private LTE, and 5G architectures (both operator and private) and supports ITU-T G. 8265 and G.8275 frequency and phase profiles. The product features multiple oscillator options to deliver a range of holdover performance.
Ts2 utilizes GNSS (GPS, Beidou, GLONASS, QZSS, and Galileo), PTP, and Synchronous Ethernet as input references and generates PTP, SyncE, and timing signals (frequency, 1PPS, and ToD) as outputs. The Multi-Sync Gateway features dual 1 GbE ports for both copper RJ45 and optical connections. It provides all the relevant timing interfaces such as GNSS, 1 Pulse Per Second (1PPS), Time of Day (ToD) (input / output), and frequency (programmable output).
The true innovation in this product lies in its simplicity, high performance, scalability, and cost-effectiveness. The Ts2 has some unique features designed to make it easily manageable and provide resilient performance when reference sources are lost.
