Searching for Keymile DUP14

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. 

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.  

The definitive ‘Dynanet’ spares list

Nokia ‘Dynanet’ PDH Transmission products

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.

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.

Optical Teleprotection Signalling (TPSO) Equipment (C37.94)

Electrical power systems protection

Teleprotection for power systems protection has been deployed by utility companies for many years. It’s purpose is to monitor the condition of the Electricity Grid, isolate faults, disconnecting faulty parts from the rest of the network and thereby prevent damage to critical parts of the power infrastructure.

Teleprotection is a physical interface between the telecommunications equipment and the electrical grid protection relays. When a fault occurs, the protection system switches on circuit breakers or reclosers to avoid a fault rippling through the network. Also, in the event of an outage, teleprotection helps restart power to a part of the grid.

Early teleprotection systems used voice-frequency signalling technologies. These were replaced by digital electrical Tele-Protection Signalling (TPS) equipment using 4 or 8 command channels encoded into a 64kbit/s standard digital data channel, in accordance with the ITU-T G.703 recommendations. This brought dependability and interoperability of systems, meaning that dedicated channels were no longer required as any standard digital transmission network could be used, separate from the power system.

This was later enhanced by the development of Tele-Protection Systems with Optical (TPSO) interfaces, which allowed the direct fibre connection between the teleprotection device and the primary multiplexer. 

The IEEE C37.94 standard for TPSO interfaces

The IEEE C37.94 standard defines an optical fibre interface for use between teleprotection systems and digital multiplexer equipment, operating at a data rate of nx64kbit/s. 

This allows the interconnection of different vendors teleprotection equipment with different vendors multiplexer equipment, without any restriction on the content of the nx64kbps data, using up to 2km of 50μm or 62.5μm multimode (or up to 20 km of 9μm single-mode) optical fibre.

Critical Systems deployment 

Teleprotection systems are typically installed in high-voltage transmission grids where distances are usually greater than in distribution grids and play a critical role in preventing instability in the grid and damage to expensive substation equipment.

Teleprotection systems monitor conditions on transmission lines and coordinate tripping of the transmission lines to quickly isolate faults. 

A teleprotection system usually has two components: a protection relay, which executes the actual switching; and the teleprotection equipment itself, which is the interface to the mission-critical communications network. 

Typical Teleprotection Systems Network

To ensure that the power systems are properly protected, real-time exchange of status information messages and commands between teleprotection equipment must be reliably transferred with tightly-controlled latency over a deterministic mission-critical communications network, traditionally composed of TDM multiplexers and optical PDH or SDH equipment. 

Nokia ‘Dynanet’ TPSO 24204

An example of a vendor’s multiplexer is the Nokia ‘Dynanet’ equipment family. This utilises the TPSO 24204 interface unit for connecting the teleprotection devices directly to the primary multiplexer. This provides four IEEE C37.94 standard interfaces, with nx64kbit/s optical data channels (where n is 1 to 12).

TPSO – 24204

Because of the direct connection, there is no need for a separate converter to change the optical connection to electrical. This eliminates electrical interference and data corruption caused by disturbances from the high voltage power line.

Maintenance of Legacy networks – Spares, Connectors and Cables

Continued use of Legacy Telecoms  – Nokia PDH ‘Dynanet’

Public Operator and Private Network Customers across the Telecoms, Utilities, Transport and Public Safety markets maintain ‘legacy’ infrastructure for mission critical applications, which continue to deliver good operational service with high availability. 

Typical products utilised are those from the ‘Dynanet’ family of PDH Transmission telecoms products, which 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. 

In order to maintain these systems and networks, it’s still possible to supply spares from surplus stocks and refurbished items to keep networks operational. 

Don’t forget the Connectors and Cables!

One challenge for the continued use of existing infrastructure, particularly when installing replacement parts, is sourcing the appropriate specialised and often propriety connectors for cabling of interfaces and management connections.  

Regarding ‘Dynanet’, fortunately some products can still be produced, notably the Euro / SMB connectors, along with the DCN Adapter C4.0, related management software products and other items such as the TPS64 and NDUE. Listed here are a few of those currently available new:
