A rescue programme for former Nortel Networks customers has been launched by IT infrastructure repair firm Comtek.
Radware, which acquired Nortel's Alteon switch business, has undertaken to support existing customers for five years, but other former Nortel customer face uncertainty.
"We are already seeing an increase in the number of enquiries from former Nortel customers from a far away as Taiwan," said Phil Mackay, sales director at Comtek.
The firm has invested in additional equipment and skills to meet the expected growth in demand for repairs to Nortel-based infrastructure.
Global and other carriers of voice and data traffic want to continue using Nortel equipment to avoid unnecessary upgrades in the economic downturn, said Mackay.
"There is a growing recognition that repairing rather than replacing IT and telecoms infrastructure can greatly extend the life of legacy systems," he said.
Comtek is headquartered in Deeside in Wales and has other repair sites at Reading in England, Frankfurt in Germany and Amsterdam in the Netherlands.
The firm's rescue programme is aimed at providing a repair service for any legacy and end-of-life Nortel equipment.
"Comtek's warranties on many of it repairs exceed those on new products without forcing companies into support contracts," said Mackay.
