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.
The XMP1 product is multi-service access / transmission node equipment capable of PDH data rates of 8Kbps to 34Mbps and SDH STM-1 or STM-4. Originally manufactured by Marconi, the range was taken over in later years by Keymile and Bosch before being discontinued.
The system is still in service, customers include Utilities and Transport organisations, and typically deployed as a terminal multiplexer or as an ADM (Add-Drop-Mux). It can provide point to point or leased line in a corporate network for POTS, data, LAN, IDSN etc.
The building blocks of the system are the central unit which provides control and management, the SDH cards for STM-1 and STM-4 aggregation and the line units which provide uplink in the form of E1, E3 or SHDSL which can be copper or optical. 8 and 16 Slot versions were available as well as an SL (slimline) variant.
Spares and Repairs for continued long-term operation and maintenance
Whereas these products are no longer manufactured, @YellowsBestLtd is able to supply a limited amount of spare parts and/or offer repair services in order to aid customers in keeping their networks operational. There follows a non-exhaustive list of typical parts that can be supplied, we would be very pleased to receive specific requests for items that are needed.

The Sagem ADR product range was an SDH Add-drop Multiplexer (ADM) product family designed as a flexible platform for Metro Access and Metro Core, backhauling, microwave radio and Utilities infrastructure networks.
ADR155c
The family included ADR155c and ADR622, STM-1/STM-4 ADM, and ADR2500 ‘eXtra’ and ADR10000, STM-16/STM-64 multi-service NG SDH. This range was managed by the IONOS Network Management System (NMS) which also managed Sagem Primary Multiplexers, PDH and SDH microwave radio and DWDM systems.
ADR622
The ADR family was deployed worldwide with more than 60,000 units over 5 years.
Comprehensive Functionality
ADR2500 ‘eXtra’
The ADR platform offers a large variety of interfaces from E1 and E3, Fast Ethernet and Gigabit Ethernet, enabling the provision of a wide range of end Customer services. Transmission protection for guaranteed QoS is provided with SNCP, MSP, MS-SPRing as well as common unit and tributary protection.
The STM-16 network units can be used for multi STM-1 or STM-4 and local-cross connect functionality thanks to a fully non-blocking switch matrix.
The modular and flexible housing provided by the ADR155c (2U), ADR622 (6U) and ADR2500 ‘eXtra’ (14U) 19” and ETSI subracks provide a flexible mix of office, street cabinet and equipment room deployment.
ADR10000
Continuing to provide operational service
The ADR family of SDH products continues to provide operational service with various global Operator, Utilities and Transport companies.
@YellowsBestLtd supports requirements to maintain these networks by supplying various spare part items from refurbished and surplus stocks in perfect working order.
There follows a list of the main elements that are typically provided, though other items can be provided. Please let us know of any specific requirements you may have. We look forward to being of assistance.

Continued Supply of Spare Parts – Surplus and Refurbished Items
@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).
For the ‘Dynanet’ range, we should be able to continue to supply refurbished and surplus equipment for as long as required, but the effect of the discontinuation of production is squeezing the availability of remaining stocks, with a consequential impact on pricing.
Hence, for those customers continuing to maintain their networks, it is recommended to consider purchasing spare parts whilst there is still availability. Please get in touch to advise what you need!
From time-to-time, hardware elements within infrastructure systems fail, and repair services are required for a diverse range of parts procured over a considerable period of time, from a multitude of Original Equipment Manufacturers (O.E.M.s), some of which no longer exist.
YellowsBest is able to provide a comprehensive repairs management service for both new and old equipment items, all to a standard equivalent to the original working condition and with warranted operation.
Component Level Repairs Example: SES Displayboards
An example of the type of equipment that we are often asked to assist with is the MS1 Matrix LED ‘displayboards’ produced by SES and used for professional signage applications.
LED ‘displayboards’
Typical issues to deal with are Faulty LEDs, damaged capacitors and broken sockets, which have occurred in operational use over time. Adding to this are problems stemming from heat gun damage and resoldering caused by previous ‘user fixes’. But these issues are addressable and the boards restored to full working condition.
Other types of equipment for repair services include Telecommunications products, power supplies and CCTV cameras.
Typical Items for Repair Services
Reduce – Reuse – Recycle
@YellowsBestLtd helps Customers with their operational needs, and one aspect is to #Reduce the demand for avoidable whole-scale replacements through a combination of #Reuse of refurbished spares and repair of system elements. When removal and disposal of no-longer serviceable infrastructure parts is necessary, we can also assist with the resale and #Recycle for ‘value recovery’ of valuable materials.
Most customers have implemented their private network infrastructure systems over a number of years, and for many their operational requirements have not changed. Consequently, it makes more sense both financially and environmentally to maintain these systems rather than embark on complete change-outs. We can assist by supplying critical and hard-to-find spare parts and hardware repair services, even when the systems have been declared ‘obsolete’ (i.e. no longer in production) by the O.E.M. We look forward to hearing from you.
Phased Discontinuation of Production – 31st May 2019 – 31st January 2020
The production of the ‘Dynanet’ family of PDH Transmission telecoms products, first introduced by Nokia over 20 years ago, and continued in recent years by DNWP, is finally being ended.
This product range has 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.
Essentially almost all the old equipment items, with a very few exceptions such as the TPS64, are being completely discontinued in a phased way according to these milestones, which have already commended:
31st May 2019 – DM8 Multiplexers, DF2-8 Optical Terminals, RPSA
31st October 2019 – DM2 Multiplexers, Subs/Exch & VF Cards, DN2 IU2, Service Terminals, V.28/V.11 DIU
31stJanuary 2020 – DB2, DN2 CU & BPU, G.703 & V.110, DIU, Ethernet I/F, Ring Gen, NDM 19” Subrack, NDA
@YellowsBestLtd satisfies customer product sourcing requirements for current and ‘legacy’ equipment technologies.
Should you wish to read the full ‘ramp-down’ notice and know more about obtaining equipment before it is no longer available, then please get in touch.
The UMUX platform provides carrier-grade reliable multi-service multiplexing and aggregation functions over copper and fibre networks. A variety of voice (POTS, FSX, FSO, ISDN) and data (e.g. G.703, V.11, V,24, V,35) interfaces, SHDSL and Ethernet (including PoE+ and EoS) services are available.
UMUX module range
The modular and flexible housing provided by the UMUX 1500 (8U, 21-slot) and UMUX 1200 (4U, 8-slot) 19” subracks provide the perfect solution for all applications and locations, offering redundant controller and power supplies.
‘Legacy’ telecoms history
The UMUX SDH product portfolio was originally launched 1991 by Ascom, which subsequently became Keymile.
In 2003, by when 70,000 units had been deployed worldwide, the ‘enhanced’ UMUX multiservice access platform was introduced, offering the delivery of ATM, TDM and IP based services from the same platform, with support for IP/Ethernet, ADSL, VoDSL and G.SHDL.
Keymile was sold to ABB in 2017 when the UMUX range was discontinued, and then was acquired in 2019 by DZS.
Continuing to provide operational service
The UMUX, together with the UNEM network management system and ‘sister’ LINERUNNER and MILEGATE products, continues to provide operational service with various global Operator, Utilities and Transport companies.

Dynanet Subtrack
@YellowsBestLtd has supported requirements to maintain these networks by supplying various spare part items from refurbished and surplus stocks in perfectly working order.
However, demand has recently reduced and warehouse space is needed, so now the time has come to recycle / dispose of a large proportion of the remaining equipment. Consequently, there remains a short-term opportunity to obtain any items still required to maintain existing deployed infrastructure, before the products are gone.
Here is a stock list of the main items currently available, though there may be a few additional parts that can be supplied. Hence, please check and if you do have any requirements, please let us know – before it’s too late! We look forward to hearing from you.

@YellowsBestLtd our mission is to provide our Customers with Management Services and Solutions so their infrastructure networks continue to serve and perform – “Keeping Customers Operational”
Needs vary from the launch of the latest IT and Telecoms technologies through to the support of well-established legacy systems.
Given that each organisation is unique, both in its business practices and deployed infrastructure, then we find that its best to take a flexible approach and provide tailored services to suit exacting demands.
Our no-cost and no-obligation Customer consultation is all about finding out needs, regardless of technology or manufacturer, and then sourcing the required solution(s), which may mean seeking out difficult to obtain products or requiring the supply of specialist services. So in essence, it’s not about us ‘selling’ them something we have, but rather our clients ‘telling’ us what to provide. Making it easier and more convenient for busy procurement and operational teams, saving them effort, time and cost.
We’re always keen to see how we can enhance our range of #business services, increase the #enterprise infrastructure we support and expand our mix of #systems solutions to supply the required #technologies and products for our customers.
Please help us understand what services would be of interest to you to support your systems requirements, by getting in touch; we look forward to hearing from you.
Most Customers’ infrastructure systems now consist of a wide range of technologies from the very old to relatively recent, having been built to serve operational requirements for a number of years. In many cases, these requirements don’t significantly change, and it therefore makes sense to keep these systems in place to maximise the use of the investment and avoid whole-scale change-outs that would be costly, disruptive and unnecessary.
@YellowsBestLtd locates hard-to-find replacement spare parts to keep legacy infrastructure in operational service that has been deemed ‘obsolete’ by the manufacturers, as well as supplying additional spares for newer systems that can be used to increase capacity or provide alternative interfaces.
Typically we provide refurbished spares, tested and working, but often it is the case that unused products from surplus stocks can be supplied. Hence for both old and new systems, we are usually able to source parts at very commercially competitive rates and with short lead-times.
Here is a selection of items that we’ve recently been helping customers procure or obtain parts for. Keen to hear what requirements you may have, so please get in touch.
