Spares

Support for new and legacy systems

Our mission is with “Keeping Customers Operational”. One of the ways we accomplish this aim is by supplying spare parts for infrastructure systems, which 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.

Sometimes new product spares can be sourced, either manufactured to order, or from surplus stocks. Often when product ranges have been discontinued, the items can still be supplied as refurbished, working and tested elements, having been extracted from decommissioned networks.

Requirements for spare parts vary across a wide range of technologies and are usually sourced to support ‘legacy’ networks, but we also receive requests for new products to supplement the scope and capacity of more recently deployed systems.

@Yellowsbestltd would be keen to hear from you should you have any spares requirements. We have various elements in stock, and anything we don’t have immediately available we can usually source very quickly. Please get in touch to let us know what you need.

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.

Starting to look a lot like Christmas …

Another unusual year has nearly gone; it was hoped that the disruptions and restrictions would be behind us by now, but it seems not to be the case for a while longer.

Despite the difficulties and uncertainties caused by the pandemic and Brexit, @YellowsBestLtd has been pleased to continue work with our suppliers and serve our Customers, providing Spares and Repairs Solutions and Consultancy and Support Services. Many thanks to all for assisting in our aim of “Keeping Customers Operational” throughout this year, and we hope to continue to work with you in the New Year.

We wish you and your family season’s greetings and most of all to keep well and safe. 

Best Wishes and kind regards.

Sagem ADR SDH family

‘Legacy’ telecoms history

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.
