Continuing in Operation, Still Available for Supply
The ‘Dynanet’ product family is a range of PDH telecommunications products first launched by Nokia over 20 years ago. This equipment has proven to be incredibly reliable and dependable, extensively deployed by Operators, Utilities and Transport companies to provide resilient and highly available transmission networks.
A continuing challenge for public and private network owners is the ongoing maintenance of infrastructure systems to support their business needs. In many cases, it makes sense to continue to operate legacy systems which are still fulfilling unchanged requirements, rather than contemplate costly and time-consuming change-outs and replacements.
Keeping Customers Operational
@YellowsBestLtd seeks out new products and legacy equipment spares to assist with these aims. Recent enquiries have been fulfilled supplying refurbished and surplus stocks of equipment cards, as well as built-to-order cables and connectors to suit exact requirements.
There follows a few examples of items we have recently supplied. Also, our more extensive Definitive ‘Dynanet’ spares list here provides details of many items still available from surplus and refurbished stock. We would welcome any enquiries for the supply of similar or alternative parts, or support services to provide hardware repairs. Please get in touch; we look forward to hearing from you!
Public Safety, Utility and Transport organisations over many years have deployed Private Mobile Radio (PMR) infrastructure equipment with high availability and reliability to provide to provide dedicated, secure communications networks.
Modern implementations of PMR utilise the digital TETRA standard, which provides interoperability between systems and terminals from a range of manufacturers.
@YellowsBestLtd our mission is “Keeping Customers Operational”, by continuing to provided spares solutions, hardware repairs and support services to ensure continued long-term operations and maintenance.

Repairs to elements such as modules and cards of infrastructure hardware is one way we achieve our mission of “Keeping Customers Operational”. A good and recent example is Motherboards for display systems. These are from established, long-standing and therefore proven and fit-for-purpose systems. It therefore makes sense to maintain and extend the life of these parts.
Typical with such ‘legacy’ elements is that the level of complexity of the items is not excessive, meaning that repairs using discreet components is perfectly feasible, unlike more modern integrated systems which use specialised parts that cannot be freely or cheaply obtained or impossible to disassemble resulting in them being classed as ‘BER’ (Beyond Economic Repair). This is ultimately costly and disruptive, requiring wholesale replacements.
@Yellowsbestltd would be keen to hear from you should you have any repairs requirements. We would welcome receiving any defective items you have in order to perform a no-cost assessment to establish the feasibility and likely cost of restoration. Please get in touch to let us know how we can help.
Call out for any requirements for Network Management Systems cables
In addition to satisfying world-wide customer product sourcing requirements for current and ‘legacy’ equipment technologies, @YellowsBestLtd also seeks out peripheral items such as Network Management System (NMS) cables.
These items may be minor in nature and originally low-cost, but they are vital for continued use and configuration of transmission nodes via management systems which evolved way before modern wireless technologies and smart phone ‘app’ based tools. Such specialist cables are becoming increasingly hard to find, since once used and damaged, they are likely to be disposed of rather than refurbished, and no new replacements are being produced.
However, in the absence of surplus stocks, it is possible for us to arrange for the manufacture of specialist cabling products including those for NMS. Due to the particular nature of the connectors utilised, these have to be specially sourced, but the cable materials themselves can be specified and applied accordingly. However, it is the orginal design information that is most critical to obtain the right functionality and compatibility.
Whatever your requirements, if you are seeking equipment or cabling for new or legacy systems, then please let us know as we can usually assist. We look forward to hearing from you.
Call out for any stocks of Keymile’s Dual Power Input Modules (DUPI4)
@YellowsBestLtd we satisfy 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 have stocks of surplus and refurbished products from the Keymile UMUX range which we are able to supply to assist customers in maintaining their operational networks.
However, one item not in our stocks that is of immediate interest to several of our clients is the Dual Power Input Modules (DUPI4).
We are urgently seeking supply; if you can assist, please get in touch!
These items provide the ultimate power protection upgrade:
Unit centralises alarm functionality and power input control
Delivers built-in redundancy
Power protection for both sub rack and fan unit
Increased the VDC availability
The DUPI4 acts as a dual input power decoupler that selects between two independent VDC power feeds and delivers them directly to the sub rack’s power input. Thus, the DUPI4 ensures uninterrupted service delivery since the power feed change over is instantaneous.
‘Legacy’ telecoms history
The UMUX SDH product portfolio was originally launched 1991 by Ascom, which subsequently became Keymile. Keymile was sold to ABB in 2017 when the UMUX range was discontinued, and then was acquired in 2019 by DZS.
Comprehensive Functionality
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.
Spares for 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.
@YellowsBestLtd supports requirements to maintain these networks by supplying various spare part items from refurbished and surplus stocks in perfect working order.
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 original Nokia 8110 ‘slide’ mobile phone was immortalised in the film ‘The Matrix’ in 1999.
Back then, people used mobiles for mostly … calling people, and the occasional text message. Ok, and a few plays of the game ‘snake’!
It was affectionately referred to as the ‘banana phone’ due to its unusual curved shape, though the only colour you could get it in was black.
Since then, we have had a revolution in data networking and an explosion of app-based touch-screen smartphone slates. So much so that people are finding themselves addicted to looking at these personal pocket computers ‘all the time’.
Consequently, there is now a growing trend of wanting a ‘digital detox’ and to get back to basics with a simple, cheap device that keeps you in touch without taking over your life.
The updated Nokia 8110 4G ‘Banana’ phone
In 2016, HMD Global Oy took over the licence to produce Nokia branded phones, and have since been revisiting and refreshing classic designs including their take on the ‘slide-phone’ with the 8110 4G.
Nokia 8110 4G – Ready for ‘unboxing’
As well as traditional black it’s available in bright YELLOW, making it this time the true ‘banana phone’.
Nokia 8110 4G – The True ‘Banana Phone’
With a design that harks back to those simpler days, it never-the-less comes with a number of advanced features.
What’s Good: Simple ‘Real’ number and calling keys for phoning and familiar ‘Nokia’ menu structure providing Call log, Contacts, SMS. Twin SIM cards for 4G calling flexibility at home and away. WiFi. Removable micro SD-card for expandable storage. Replaceable battery. Music Player, FM Radio and headphone jack. Camera, gallery and video player. Internet Browser and e-mail. Flashlight, Notes, Recorder, Calculator and Unit Converter. Clock and Calendar. Google Maps and directions.
What’s not-so-great: No touch-screen! Small display. Minimal App support. Fiddly ‘old school’ text-entry. Slow and limited internet capabilities. Low-resolution imaging and video, and no front-facing 2nd camera. Cursor keys surprising small and tight to bottom of display making scrolling more awkward than it ought to be. Having to take the battery out to insert / remove the memory card.
What’s Fun: Answering calls with a slide (and end them again by closing. Freedom from ‘smartphone’ addiction, though if you really must, WhatsApp, Twitter, Facebook and Youtube can just about be used. And ‘snake’ (though a strange ‘modern’ version), plus some other games and more can be downloaded.
Nokia 8110 4G: Apps and Maps
In summary, this is a feature-packed but ‘basic’ mobile which brings an iconic design up-to-date, is fun to have, does the basics and a bit more.
Keeping connected with a digital detox
This Nokia ‘featurephone’ doesn’t pretend to rival ‘smartphones’ in capabilities. But useful as a supplementary device in case of a flat battery, and good for just keeping connected while getting on with life. Handy too when wanting to avoid carrying a very expensive piece of hardware when active or travelling.
There has been a trend to have just one device with as many functions as possible packaged in, with inevitable strain on battery life. It can however be sometimes preferable to use a Hi-Res player for music, a quality camera for photography, a tablet for internet browsing and a phone for – phoning!
So not a complete digital ‘detox’, rather just providing another alternative option to keep ‘plugged in’ to today’s ‘Matrix’ world of communications.
