## Summary

This tender presents substantial business growth opportunities, particularly for companies specialising in telecommunications maintenance and support. The scope includes long-term support arrangements, technical and helpdesk support, as well as repair and return services for specific network equipment. Businesses experienced in managing End of Life/End of Support equipment and offering high-level technical assistance would be well-suited to compete. A successful bid could secure significant revenue over a contract period starting from January 2026 to December 2029, with an estimated contract value exceeding £5 million.

## Notice

Network Rail have their own National SDH Network, managed by their Network Management Centre (NMC). The network allows Network Rail to carry and transmit voice, data, signalling and radio services to the operational railway for the support of safe train movements. There are plans for a renewal and replacement of this network. However, this will take many years to complete. The SDH equipment is End of Life (EoL) / End of Support (EoS). As a result, standard Original Equipment Manufacturer (OEM) support and extended support is no longer available or has limited availability. Network Rail is seeking information from qualified suppliers who can provide a comprehensive long term support arrangement for the National SDH Network. This includes Repair & Return of Alcatel SDH Transmission Equipment and equipment forming the Data Communication Network (DCN) for the SDH network, Remote Technical Support and Helpdesk Support (Level 3/Tier3).
