The definitive ‘Dynanet’ spares list

Nokia ‘Dynanet’ PDH Transmission products

For many years, the ‘Dynanet’ family of PDH Transmission telecoms products have well served Public Operator and Private Network Customers across the Telecoms, Utilities, Transport and Public Safety markets with high availability mission critical infrastructure, and indeed some networks are continuing to provide good operational service.

They were first introduced by Nokia over 20 years ago, and were continued in recent years by DNWP. Production of the majority of the product range was ceased in 2019. 

Spare parts for continued operational service

@YellowsBestLtd satisfies world-wide customer product sourcing requirements for current and ‘legacy’ equipment technologies from a wide range of Original Equipment Manufacturers (O.E.M.s).

In particular, we are able to supply products from the ‘Dynanet’ range, given that we have a significant amount of refurbished and surplus equipment items in stock for immediate delivery. Hence there continues to be spares support for current and even increased deployed networks.

Comprehensive Stocklist of ‘Dynanet’ Spares

Whereas the ‘Dynanet’ family contained a wide range of products produced and supplied over many years, some of which are relatively obscure and unlikely to be needed, there are a number of core items that have proved to be always in demand by Customers. Consequently, we have endeavoured to create a comprehensive stock list, containing part numbers, product codes and descriptions and images which is presented here, and would welcome any enquiries you have for spares requirements that we can fulfil. If however, you are seeking something more unusual, then please let us know as we can usually assist. We look forward to hearing from you.
