Three years milestone

Three years completed; onward in our fourth year!

@YellowsBestLtd has now reached the significant milestone of completing three years of trading; something often useful to be able to state when qualifying for opportunities and registering with business customers.

Our aim continues to be “Keeping Customers Operational”; understanding requirements and fulfilling them by providing a range of management services and solutions, including:

  • consultancy, such as business development planning3_years_services
  • technical support, e.g. day-rate engineering, NMS assistance
  • systems supply, including legacy IT servers / workstations
  • spares for infrastructure, in particular telecoms and CCTV cameras
  • repairs at module and component level, e.g. LED displayboards
  • value recovery through reverse logistics, resale and recycling

As we move forward in year four, we’d very much like to discover what else to provide to our existing Customers, as well as what would be of interest to potential clients. We’re always keen to enhance our range of #business services, increase the #enterprise infrastructure we support and expand our mix of #sustainable solutions we offer for supply and maintenance of new and legacy #technologies and products.

Please get in touch to discuss your challenges; whether you’re implementing new systems or maintaining existing infrastructure to serve your operational business needs. We look forward to hearing from you.

Keeping Customers Operational – ‘telling’ not ‘selling’

@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.

“TESTERS” – Test Equipment to suit all deployed technologies

Customers who own infrastructure systems usually require some form of test equipment to assist with the build, operation and maintenance activities.

Given the mixture of old and new technologies now deployed, consequently the range of available test equipment options has grown considerably. And like the infrastructure systems themselves, new functionality demands and obsolescence issues also affect the associated test equipment needs and availability.

@YellowsBestLtd assists Customers by sourcing the required test equipment, supplying either modern or legacy units. Often refurbished ex-hire equipment in excellent condition and at commercially attractive prices makes sense over leasing. This ensures the continued availability of sets of the appropriate specification, which may become discontinued by the manufacturers over time.

If necessary, we can also arrange the repair of existing units, especially those that perform very specific functions that cannot easily be replicated with more recent equipment.

There follows a brief description of many of the types of test equipment available; we would be very keen to hear from you to understand your specific requirements, so please get in touch!

Calibration Checkboxes

Calibration checkboxes, or electrical checkboxes, are used for routine observations of test equipment and allow users to maintain accuracy in between official calibration procedures. Suitable for use with PAT testers and with other testers and instruments.

Calibration Checkbox

Component Analysers

These test the efficiency and status of components including transistors and capacitors. An essential instrument for development engineering when specific components are used in product design.

Component Analyser

Legacy and New Infrastructure Spares

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.

Alcatel AnyMedia Access System
Bosch MIC-400, -550 and -7130 Cameras
Dialogic I-Gate 4000 System
Huawei UMG8900 Node
Marconi ST68NB Matrix and 1HAT60558ADV
Meraki MS250 switch and MR52 access point
Motorola Terayon DM6400 Network CherryPicker
Nokia Dynanet PDH Subrack and 9500 MPR ODU
