Many operators and service providers continue to rely on proven legacy infrastructure to support critical services across their networks. While these platforms may no longer sit at the centre of vendor roadmaps, they still play an important role in delivering stable, cost-effective connectivity. The challenge is ensuring ongoing support, access to reliable spares, and technical expertise when original manufacturer support becomes limited, expensive or unavailable.

Carritech has expanded its legacy support portfolio to help meet that challenge. We now provide support for the Alcatel 1641 SX, Huawei CX600, Nokia GPON ISAM/ASAM, and Cisco ASR 900 Series, including the ASR 903 and ASR 920.

For organisations still operating this equipment, Carritech offers a practical and commercially sensible way to extend asset life, maintain network performance and reduce the operational risks associated with unsupported infrastructure.

Supporting Networks Beyond OEM End-of-Life

Legacy platforms do not stop being valuable simply because they are older. In many live environments, they continue to perform critical roles in transport, access and service delivery networks. Replacing them prematurely can create unnecessary cost, disruption and project complexity. In many cases, the better option is to maintain and support existing infrastructure strategically for as long as it remains fit for purpose.

Carritech works with operators, service providers and enterprise network owners to keep these platforms operational through a combination of:

• Spare part supply
• Repair services
• L3 remote technical support
• Asset management

This approach helps customers preserve uptime, improve resilience and make better commercial decisions around maintenance, replacement planning and stock holding.

Newly Supported Platforms

Alcatel 1641 SX Legacy Support

Il Alcatel 1641 SX remains a recognised platform in networks where stable transport infrastructure is still required. As these systems age, sourcing dependable parts and specialist support can become increasingly difficult.

Carritech provides support services for the Alcatel 1641 SX to help operators continue running installed equipment with greater confidence. From replacement hardware to repair and technical assistance, we help reduce downtime exposure and extend the useful life of deployed assets.

Huawei CX600 Legacy Support

Il Huawei CX600 is widely recognised as a metro services platform that continues to support important routing and service delivery functions in many networks. Where these systems remain deployed, access to ongoing support is essential for operational continuity.

Carritech now offers legacy support for Huawei CX600 platforms, helping customers secure spares, access repairs and obtain L3 remote technical assistance when issues arise. This allows operators to keep key infrastructure in service without relying solely on limited or costly traditional support routes.

Nokia GPON ISAM/ASAM Legacy Support

Il Nokia GPON ISAM/ASAM platform continues to be relevant for operators supporting access network infrastructure and installed broadband environments. As networks evolve, many organisations still need dependable support for these existing platforms while they manage long-term upgrade strategies.

Carritech helps bridge that gap with specialist legacy support services designed to keep Nokia GPON ISAM/ASAM equipment available, supportable and commercially viable. Whether the need is spare parts, repair turnaround or expert technical input, we help reduce the pressure of managing ageing access infrastructure.

Cisco ASR 900 Series Legacy Support

Il Cisco ASR 900 Series, including the ASR 903 and ASR 920, remains an important platform for many operators supporting aggregation, access and service edge requirements. As these units move further into legacy status, maintaining support coverage becomes increasingly important.

Carritech now supports Cisco ASR 900 Series platforms with services that help operators reduce the risks of unsupported hardware. With access to replacement parts, repair services, technical support and asset management expertise, customers can continue to operate these systems with improved confidence and control.

What Carritech’s Legacy Support Includes

Fornitura di ricambi

Access to quality spare parts is essential when supporting mature network infrastructure. Carritech helps customers source the hardware they need to maintain service continuity and respond quickly to failures, without the uncertainty that often comes with ageing platforms.

Repairs

Repair services provide a practical alternative to full replacement, especially where platforms remain operationally important but budgets are under pressure. Carritech supports customers with repair options that help lower costs, reduce waste and keep valuable equipment in service for longer.

Supporto Tecnico Remoto di Livello 3 (L3)

When technical issues affect legacy infrastructure, internal teams often need fast access to specialist knowledge. Carritech’s L3 remote technical support helps customers troubleshoot issues, stabilise services and reduce the impact of complex faults across older platforms.

Gestione degli Asset

Managing legacy infrastructure effectively is not just about fixing failures. It also means understanding what equipment is deployed, what spare stock is available, what should be repaired, and where value can still be recovered. Carritech’s asset management support helps customers take a more structured approach to lifecycle planning, resilience and cost control.

Why Legacy Support Still Matters

For many network operators, legacy equipment is not simply old hardware. It is infrastructure that still performs an important job. Replacing it too early can drive unnecessary capital expenditure, while leaving it unsupported can increase operational risk.

A structured legacy support strategy helps organisations:

• Extend equipment life
• Maintain network reliability
• Reduce support risk
• Avoid premature capital spend
• Improve value from installed assets
• Support circular economy and sustainability goals

By combining technical expertise with practical lifecycle services, Carritech helps operators keep critical legacy platforms working harder for longer.
