Release 20

The Nokia 7250 Interconnect Router R-series (IXR-R-series) density in compact, modular, extended-temperature form factors. Routers and mission-critical applications.

Automation

The 7250 IXR-R series uses the Nokia Service Router Operating System (SR OS) and is managed by the Nokia set of service management features that automates new service delivery and reduces operating cost. (SDN) interfaces enable best-path computation to

path computation by a path computation element (PCE) function in the SDN controller.

The modular architecture used by routers in the

7250 IXR-R series supports a variety of deployment

options. High-density 1GE/10GE/25GE/40GE/100GE media-dependent adapter (MDA) cards accommodate future growth. CFP2 DCO optics provide high bandwidth over extended distances, lowering the total cost of operations. Legacy interface cards support transport over existing TDM interfaces and allow for seamless migration to a next-generation IP/MPLS infrastructure. fans increases system lifetime and reduces maintenance with 300 mm ETSI-compliant cabinets. This capability is typically not available with front-to-back cooled systems. control-plane performance using a multi-tasking, multi-priority operating system to take full advantage of multi-core processors combined with symmetrical multiprocessing (SMP). Network and powerful operations, administration and maintenance (OAM) and security features.

The 7250 IXR-R series provides precise timing and

accurate synchronization to meet the stringent requirements of 4G/5G mobile base stations and other networks. It improves timing accuracy over packet networks by combining built-in architectural features with Global Navigation Satellite System (GNSS) capabilities, ITU-T Synchronous Ethernet (SyncE) and the Nokia Bell Labs IEEE 1588v2 algorithm. Powerful QoS mechanisms deliver best- in-class performance by minimizing the delay and delay variation experienced by packet synchronization technologies. Port-based timestamping delivers consistently accurate IEEE 1588v2 performance.

Granular, in-depth and scalable per-service

The 7250 IXR-R series provides comprehensive

reporting on key performance indicators such as packet discard and forward counters. These capabilities improve reliability and help service enterprise and public sector operators can ensure required treatment. The 7250 IXR-R series provides excellent protection against link or equipment failures through control and datapath redundancy options. It quickly a robust set of dynamic routing and recovery capabilities. Superior network resiliency reduces network downtime and improves the overall productivity of network operations. With a highly resilient network, network operators can reduce operating costs, improve end-user satisfaction

For harsh environments

The 7250 IXR-R series, with its extended

temperature range, mechanical hardening and robust design, meets the IEEE 1613,
