It’s a good time for watching sport, not least the arrival of the Women’s Football (Soccer) World Cup.
@Yellowsbestltd we will be following the competition with interest, and naturally following our home side! Whoever you’re supporting, good luck and best wishes for an entertaining and enjoyable event.
Wen you have time between work commitments and leisure time, we would be keen to hear from you should you have any views or news, or indeed any consultancy, solutions or support services requirements. Please get in touch to let us know how things are with you and if we can help.
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.
@YellowsBestLtd seeks out new products and legacy equipment spares, ensuring the continued long-term maintenance of infrastructure system.
Equally as important can be the necessary cables to connect data and voice circuits. Often, these are items that can be damaged and disposed of, since repair is difficult or impossible. And original supply is no longer available. Fortunately, we are able to get these bespoke items newly manufactured, specifically made to order.
Here are a few recent examples:

Although the installation of fibre broadband services have been rolling out across the UK for some time now, there still seems much confusion relating to the various services on offer.
@YellowsBestLtd has been receiving ‘Fibre To The Premises’ (FTTP – sometimes referred to as ‘Fibre To The Home’ FTTH) from @Gigaclear since our formation in 2015. We are therefore able to provide this brief summary of our experiences and comparison of the types possible and their capabilities:
Full Fibre (FTTP) – fibre runs directly to the office or house, giving the fastest and most reliable speeds. This is what we had installed by Gigaclear; a dedicated fibre line into a fibre modem which can be directly connected to using ethernet cable or via a wifi router.
Part Fibre or ‘Fibre to the Cabinet’ (FTTC) – fibre runs to the neighbourhood cabinet, and then data runs over copper lines into the building. The transmission speed and bandwidth is therefore reduced in comparison to Full Fibre. This is the type of on offer to many consumers where the local telephony provider is not able to rollout fibre replacement for the ‘last mile’ of copper connection.
Copper or non-fibre – the traditional, existing telephone lines are used to provide the broadband service. This naturally provides the slowest speed and least data bandwidth. Many communities still rely on this as the only means of internet connection, since no fibre broadband deployment has been made.
The net result is that with Full Fibre, it is possible to receive previously unheard of speeds. Indeed the maximum service on offer is so fast, it outstrips the requirements of most homes and businesses. It is therefore typical that a reduced service is selected purely for cost-saving purposes.
Our own experiences have found that the Ultrafast 300 service from Gigaclear to be more than adequate for our needs. This is a screen shot of an actual speed test of the service we are being provided with:
In many cases the ‘full fibre’ service we have chosen, approximately a third the speed of the maximum possible, is still at least 10x faster than part or no fibre services. Not only is it faster, it provides a very stable connection less prone to interference and service outages. Thought due to network backhauling connections, is not unknown for interruptions to be possible; fortunately these are relatively rare.
The main difficulty for most businesses and homes remains the lack of universal provision. Whereas we have no reservations in recommending Gigaclear’s full-fibre service, we recognise this is not available everywhere. It is just fortunate for us that rural communities like ours was prioritised in their initial service rollout.
@YellowsBestLtd our mission is in “Keeping Customers Operational”.

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.
It was hoped to be a year of ‘getting back to normal’, but unexpected world events seem to keep coming. Consequently, we have had much to deal with this year, but as it draws to an end, it is once again a time for reflection, hopefully celebrating with friends and family.
Thanks for your continued interest and support in @YellowsBestLtd, we look forward to being in touch again in the forthcoming New Year.
Here is a recent problem which would appear to be quite common. The end of the connector on a lightning cable was stuck inside the charging / accessory port. This worryingly appears to be a frequent occurrence resulting from the use of cheap, unbranded cables where the tip of the connector can break off, forming a staple-shaped piece, jamming itself into the iPhone or iPad. The result is that it is impossible to charge the device, unless the broken connector lead is retained, as it is the only one now small enough to fit into the accessory port.
This problem can render the expensive phone or tablet useless. For older out-of-warranty products it is potentially not worth a repair investigation and even with newer devices this may be classified as ‘accidental damage’, requiring extended insurance cover to avoid a significant resolution cost.
Happily, it may be possible to address the problem using the following simple technique:
Use a ultra-small, precision screwdriver. It needs to be small enough to easily fit inside the accessory port and be able to be levered across it’s width, whilst being sturdy enough not to bend or break.
Insert into the device’s accessory port, and position sideways across the width of the opening, such that the end of the tool is pressing on the inside of the port about half-way in / up.
Then, with an outwards ‘levering’ action, pull the broken connector piece out of the port.
If fortunate, this will remove the obstruction and return the device to an operational state. Naturally, success is not certain and there is the risk of causing further damage. Hence, particularly with newer devices, if you are not confident in your abilities then best to consult an electronics specialist or seek professional assistance from an approved repair centre.
The lesson from this experience is to purchase good quality, branded accessory leads and dispose of any cables where the connector shows signs of wear.
Maintenance of new and legacy systems
@Yellowsbestltd our mission is “Keeping Customers Operational”, by assisting with with the repair of parts for infrastructure systems. These are typically established, long-standing and therefore proven and fit-for-purpose. It makes sense to maintain and extend the life of these systems, as wholesale replacements will be costly and disruptive. This is particularly applicable when the service requirements have not changed, so functionality upgrades are not necessary.
Wewould be keen to hear from you should you have any repairs requirements. Please get in touch to let us know how we can help. By example, there follows a list of a few recent requests we have been able to assist with. We look forward to hearing from you with any feedback you may have.
When providing a spare parts for a Customer’s project requirements, one of the transmission cards to be used was missing its 5-way pluggable terminal block, without which, it is impossible to wire up and install.
