The ONPATH 2900 is a family of highly scalable physical layer switching systems with universal module slots, designed to accommodate a variety of high-performance connectivity and monitoring applications. The systems include a fully redundant architecture with hot-swappable, field replaceable parts for the industry’s highest availability and help network managers conserve time, increase utilization, and save money compared to manual patching or complex mesh switching architectures.
The ONPATH 2900 platform solves connectivity and monitoring challenges for a variety of high-performance applications:
ONPATH’s patented 3-stage switching technology is the heart of the UCS 2900 platform, providing the industry’s most scalable and reliable switching system of up to 4,096 non-blocking and over 100,000 meshed ports. The HorizONTM management and monitoring software offers the highest security and integrated diagnostics to simplify connectivity management with point-and-click provisioning and full remote control of the UCS 2900 system.
The modular architecture of the 2900 Series enables a “pay-as-you-grow” model for the ultimate in flexibility and scalability. Each of the four 2900 systems is designed to support the capacity needed per application or site.

Mesh networking of multiple 2900 systems provides scalability over 100,000 ports
The protocol independence of the ONPATH 2900 family enables any and all protocols to be supported across a wide range of data rates from <1Mbps to 10Gbps. The universal blades or port interface modules (PIMs) provide any-to-any connectivity, while the integrated test access ports and broadcast functions allow for non-intrusive monitoring and one-to-many connectivity.

The UCS 2900 is fully compatible with the legacy interfaces associated with CCUs installed in the TELENEX 2700 switching systems. Interfaces such as RS-232, v.35, EIA 530, and T-1 can connect directly to a 422 PIM using existing DC64 cables and C3U chassis. The ONPATH 2900 offers legacy infrastructure investment protection and provides a clear path to current and future high-speed copper and optical connectivity requirements.
