Net Insight’s new Zyntai TimeNode Access is a compact, 5G enabled PTP Grandmaster that brings resilient timing to distributed edge sites over existing packet infrastructure.
Net Insight’s new Zyntai TimeNode Access is a compact, access-optimised PTP Grandmaster designed to bring resilient timing to distributed edge sites over existing packet infrastructure. Built for 5G, media, power and other critical networks, it combines local GNSS (global navigation satellite system) with secure, network-delivered timing without requiring the underlying access network to be PTP-aware.
For many mobile and critical infrastructure operators, distributed sites are connected over leased, third-party or non-PTP-aware transport, making conventional network-based backup to GNSS costly or impractical. Zyntai TimeNode Access removes that barrier by carrying secure, precise time across existing packet infrastructure and establishing standards-based PTP locally at the edge site. This gives operators the ability to strengthen GNSS resilience without redesigning the access network.
Zyntai TimeNode Access complements Net Insight's existing Zyntai portfolio with an access-optimised platform for much denser distributed deployment. By making resilient timing practical across large numbers of edge sites, it broadens where the Resilient Time Platform can be deployed and expands the commercial opportunity across mobile, media, power and other key infrastructure networks.
"The challenge is not getting precise time to one site, but doing it reliably and economically across thousands of distributed locations," said Per Lindgren, Head of Sync at Net Insight. "Operators should be able to add an independent timing source without turning resilience into a network-wide transport upgrade. Zyntai TimeNode Access makes that practical at the access edge."
Zyntai Director
Resilient, Centralised and Standards-based
Resilient time transfer can be established through four Time Transfer sessions, with regional routing, multilink synchronization and TLS/AES encryption and authentication. GNSS resilience options are also available due to multi-constellation satellite system support across the product family. The TN2020M model (see more about models below) adds L1/L5 multiband reception, OSNMA authentication, jamming detection and advanced spoofing detection and mitigation.
Standards-based PTP delivery means that up to 512 PTP clients can be deliverd at full message rate, with support for multiple profiles simultaneously. Broad standards support covers ITU-T telecom PTP profiles alongside SMPTE ST 2059-2, AES67, IEEE C37.238 and IEC 61850-9-3 for telecom, media and power applications. 10G/GbE connectivity together with SyncE, PPS, 10 MHz and NTP, allows flexible synchronization
Timing visibility and SLA monitoring are centralised by integrating the system with Zyntai Director, which brings together control and orchestration across the synchronisation network. By continuously collecting and analyzing timing and network telemetry in real time, Director helps operators monitor performance, optimize synchronisation and make quicker decisions, supporting SLA-based operations.
The system is built into a compact 40 × 219 × 181 mm enclosure for optimised Access with passive cooling, dual DC input and PoE Type 3.
Large-scale Deployments
Zyntai TimeNode Access can scale to tens of thousands of devices managed through a single orchestration system, reducing manual configuration and enabling operators to manage timing as a network-wide service rather than site by site.
Zyntai TimeNode Access will be available in two models for different deployment types. TN2020 is optimized for broad, cost-efficient access deployment, while TN2020M is designed for sites where stronger local GNSS robustness and assurance are required. Both use the same Zyntai network-based timing architecture, allowing operators to choose the level of GNSS capability and assurance required at each site.
Together, the two models extend Net Insight's Resilient Time Platform to the access edge, allowing operators to match network-delivered timing and local GNSS capability to the resilience requirements of each service and site. netinsight.net
