‘Legacy’ Infrastructure Ongoing Maintenance 

Continuing in Keeping Customers Operational

Over the last nine years, @YellowsBestLtd has sought out new, surplus and refurbished products and spare parts to assist with the aim of supporting Customers to maintain rather than replace their infrastructure networks, and as we enter our landmark tenth year, we continue to do so.

The alternative of wholesale replacements requires prohibitive investment costs and long project timescales to implement. And it can be the case that suggested replacements cannot provide equivalent operational lifetimes which therefore become obsolete faster than existing deployments.

Given the investment that has been made over many years, coupled with the fact may operational requirements have not changed, it makes sense to keep systems in place. By suppling spares, offering repair services and technical assistance, we are able to support these aims.  

Systems Replacement and ‘Value Recovery’

Eventually, it does become necessary or desirable to undertake network refreshes. Often, we can help evaluate, source and implement suitable systems.

As discussed recently at the Engineering Design Show, we are able to utilise the capabilities of a network of local manufacturers to replicate and if necessary reverse-engineer components and products to meet exacting performance requirements.  

When replacing existing networks, we are able to offer to Remove, Resell and/or Recycle existing equipment, generating revenue from the ‘Value Recovery’, and importantly ensure that items are disposed of in the most ethical and environmentally respectful way.

Equipment recently supplied and/or currently stocked

Certain product families continue to prove their excellent availability and reliability, and we are fortunate to continue to be able to provide stock of many of these items, either in new, surplus or refurbished condition.

Examples of  such products follow; should there be anything specific you require, please do not hesitate to get in touch; we look forward to hearing from you!

Keeping Customers Operational

@YellowsBestLtd continues with our aim of Keeping Customers Operational by seeking out new products and legacy equipment spares to maintain new and well-established networks. 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.

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!

‘Dynanet’ PDH Telecom Spares

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.

TETRA Equipment and Terminals for PMR Networks

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.

Hardware Repairs

Organisations that deploy, own and maintain infrastructure systems and networks make considerable investments in time and money, and it makes complete business sense to maximise the return on these investments. Even if it were desirable to make wholesale replacements, such projects take time to undertake. Ideally, if the equipment is performing satisfactorily and operational requirements have not changed, then is better to keep the existing equipment maintained for as long as possible.

Critical infrastructure systems are typically built to last, with high availability and reliable system components, and interchangeable spare parts. But sooner or later, repairs to elements are needed. During initial deployment and warranty periods, this is not normally an issue, but over time, these services become more specialised and difficult to obtain, as vendors advance their portfolios and discontinue older products.

@YellowsBestLtd specialises in ‘Keeping Customers Operational‘ by sourcing equipment spare parts and hardware repairs to modern and legacy systems. Should you have any requirements, please get in touch; we would be very pleased to hear from you, and look forward to being of assistance.

Professional CCTV Cameras

Many business operations depend on the security delivered by professional standard CCTV cameras, offering reliability, availability and a wide range of advanced features for mission-critical surveillance applications. One manufacturer that provides an extensive range of such products is Bosch; one of their latest models we feature here.

Bosch MIC IP Starlight 7100i Outdoor PTZ

This example of a robust PTZ IP camera is suitable for deployment in extreme outdoor locations that require reliable 24-hour security monitoring. It features a range of advanced imaging technologies as well as Bosch’s Intelligent Video Analytics.

Featuring a 1/2″ 2MP CMOS sensor and a 6.6-198mm motorized zoom lens, the camera captures video at resolutions up to 1920 x 1080 at 60 fps in a 58.3 to 2.1° field of view. The camera delivers color video in lighting conditions as low as 0.0047 lux and uses an automatic IR cut filter to switch from color to B&W for day/night functionality.

An integrated high-speed pan/tilt system with an anti-backlash drivetrain provides 360° continuous panning and 290° tilting at up to 120° and 90° per second, respectively. Housed in an IP68- and IK10-rated enclosure and equipped with a window defroster, the camera is suitable for use in vandal-prone outdoor locations. Audio input and output ports allow for two-way talk while an SD card slot enables onboard storage of footage. ONVIF compliance ensures compatibility with a wide range of surveillance devices.

GAIA – Earth Artwork by Luke Jerram

Fortunate to see the display of Gaia, the touring artwork by UK artist, Luke Jerram, hosted this month at the Beverley Minster.

Measuring seven metres in diameter and created from detailed NASA imagery of the Earth’s surface the artwork provides the opportunity to see our planet, floating in three dimensions. In Greek Mythology Gaia is the personification of the Earth.

Common features of the experience are a feeling of awe for the planet, a profound understanding of the interconnection of all life, and a renewed sense of responsibility for taking care of the environment.

@YellowsBestLtd helps Customers with their operational needs, and one aspect is to #Reduce the demand for avoidable whole-scale replacements through a combination of supply for #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. In this small way, we aim to make a difference in the impact we have on our planet through sustainable solutions.

Please get in touch should you wish to discuss your operational requirements and see how @YellowsBestLtd can be of assistance.
