Nokia ISAM Repair and Support Services
Keeping large access networks operational is becoming increasingly challenging as hardware ages, spares run low, and OEM support windows close. Many operators are under pressure to maintain service continuity, improve availability, and reduce costs while extending the life of existing infrastructure.
At Comtek Network Systems (UK) Ltd, we provide specialist Nokia ISAM repair services that help operators protect their networks, reduce operational risk, and extend the lifespan of their assets far beyond OEM end of life.
Supporting the Full Nokia ISAM Range
Comtek provides repair and refurbishment support across the entire Nokia ISAM product family used in copper and fibre access networks.
ISAM 7302 and 7330
Widely deployed in Fibre to the Cabinet networks. We repair VDSL2 line cards, vectoring modules, control boards, and uplink units. All modules are tested within operational ISAM chassis.
ISAM FX platforms including FX 4, FX 8, and FX 16
High capacity systems supporting GPON, XGS PON, and G.fast. We restore optical line cards, controller modules, power assemblies, and fan units to full working condition.
ISAM MX platforms
Multi service systems combining copper and fibre access. We support a wide range of mixed technology modules to help operators maintain stability through long migration programmes.
These chassis act as key aggregation points in access networks. Our understanding of ISAM switching, Ethernet behaviour, and IP integration ensures every repaired module reintegrates smoothly into live environments.
Operators maintaining ISAM platforms also rely on our Cisco ASR 9000 repair services to support their wider network estate.
Why Long Term ISAM Support Matters
Many operators will run ISAM platforms for ten to fifteen years beyond the OEM end of life date. Replacing thousands of cabinets and exchange based chassis is costly, complex, and often not aligned with operator upgrade strategies.
Comtek helps close the gap left when OEM support ends. Our services allow operators to:
- Avoid costly and disruptive platform replacements
- Maintain service availability on ageing infrastructure
- Protect investment in existing access networks
- Operate confidently even when OEM spares are no longer available
- Extend asset life in line with regulatory and commercial pressures
Our repair services support operator sustainability and circular economy goals, as outlined in our sustainability and circular economy initiatives.
This long term continuity is becoming a strategic necessity for many access network teams.
Broad Module Coverage
We repair and refurbish a wide range of ISAM modules, including:
- GPON and XGS PON optical line cards
- VDSL2 and vectoring access modules
- Control processors and switching units
- Optical transceiver assemblies
- Power supplies and power distribution modules
- Fan trays and airflow assemblies
This breadth of capability helps operators reduce reliance on large, ageing spare pools and stabilises long term maintenance plans.
Operational Testing and Quality Assurance
Every repaired module is validated using fully operational ISAM chassis and production like configurations. This includes:
- Full functional and load testing
- Signal integrity and optical performance checks
- Power stability verification
- Extended soak testing
- Preventive replacement of high risk components
We use the same carrier grade test environments applied in our optical transmission repair services for operators maintaining high bandwidth transport networks.
The result is carrier grade performance and confidence that every unit is redeployment ready.
Familiarity with Nokia Management Systems
Our engineers understand Nokia’s Access Management System and Network Services Platform. This ensures repaired modules reintegrate cleanly into provisioning, monitoring, and automation workflows with minimal disruption.
Typical Faults and Real World Challenges
Operators often come to us with:
- Port instability on ageing VDSL2 or GPON line cards
- Optical budget problems caused by transceiver degradation
- Repeated failures in power assemblies
- Shortages of key FX or 7330 modules
- Performance instability in older cabinets
- Increased fault rates during peak traffic periods
For operators also running edge routing platforms, our Juniper MX repair services offer similar lifecycle and reliability benefits.
Comtek’s repair service helps reduce operational risk, improve stability, and avoid the high cost of sourcing new or rare modules.
Logistics, Scale, and Continuity
We provide:
- Repair services for one off failures or high volume batches
- Advance replacement options
- Secure logistics and tracking
- Sustainable spare pool management
- Long term support for the entire ISAM lifecycle
Comtek will continue supporting ISAM hardware for as long as operators keep these platforms in service.
