1 Meeting name UMSUG Date of meeting 25 May 2010 Paper title Alcatel Lucent Cabinets Purpose of paper For Decision UMSUG MAY/06 Summary Alcatel Lucent would like to apply for Charge Codes for their telecommunication cabinets. However, there are a number of issues relating to the specified testing requirements and coding approach. John Ryves of Alcatel Lucent will present to the UMSUG on the operation of cabinets and answer any issues that the UMSUG have raised. 1 What Decisions are we seeking from you? 1.1 The UMSUG is invited to: Consider the equipment, issues and questions raised by Alcatel Lucent; and Recommend to SVG as to an appropriate approach for the treatment of these telecommunications cabinets under the BSC. 2 Why are we asking this? 2.1 There are a number of issues relating to the testing of the Alcatel Lucent cabinets including the use of Direct Current (DC) within the cabinets. Alcatel Lucent is also proposing an approach for to calculation the power used by this equipment for consideration by the UMSUG. 2.2 The UMSUG are requested to consider these issues and agree an approach for their treatment under the BSC. 3 More detail and justification for the recommendations 3.1 More information can be found in: MAY_06_Attachment_1_JDL UMSUG Presentation ppt MAY_06_Attachment_2_JDL NRTS Cabinet Power Consumption.doc 4 More information 4.1 Kevin Spencer wrote this paper.

10 Reason for Charge Code request Transmission stations only have NRTS equipment so all will be metered; Active Traffic Management (ATM) cabinets & 600 cabinets include equipment from NRTS and from other HA schemes; All equipment that is installed in cabinets where the HA is the supply landlord has been identified; If Charge Codes allocated, correct billing can be generated based upon each individual installation. 19/05/2010 JDL NRTS Unmetered Supplies 9

11 Methodology Procedure to accurately predict and report power consumption: The UMSUG allocate new charge codes and watt ratings to Alcatel-Lucent; The HA's TPMS team add new Category/Type/Variants linked to the charge codes in TPMS (HA's Comms inventory database); As soon as practicable, following installation of the new equipment, NRTS update their inventory; NRTS upload into TPMS, their inventory of assets where the HA are designated as the "supply landlord"; The TPMS database copies the NRTS "owned" assets onto a new sheet. The EPS team download the Comms inventory from TPMS; The EPS team carry out an EAC calculation for the NRTS assets on a new sheet on the HA's Comms Inventory Spreadsheet; The EAC for the NRTS assets is added to the existing HA Comms EAC and submitted to the DNO's at the next Comms inventory update. 19/05/2010 JDL NRTS Unmetered Supplies 10

The network connects roadside devices to a number of regional control centres. These devices include: Emergency Roadside Telephones; Traffic flow-rate detectors; Information displays & matrix signs; Traffic cameras. Each device is cabled physically to a nearby telecommunications node or transmission station (TS), where the electronic signal is digitally multiplexed on to an optical fibre or high speed digital cable connection for transmission around the system to the appropriate control centre. All cables are buried underground, normally within a purple tube or cable duct, which can often be seen on motorway roadwork sites. Most of the transmission stations deployed in the NRTS system are brick buildings, located every 10 to 15 miles or so, where signals are received and boosted to the next node. Some of these nodes are self-contained roadside Document Number Version Version Date Ref / Project No: Page. JDL /05/2010 NRTS - UMS 3 of 8

The electronic equipment is a series of separate units, plugged together as black boxes to code and decode the signals coming from or going to the roadside devices and to clean-up and amplify data passing through. Figure 1: NRTS Block Diagram 3.2 CONTROL OF THE NETWORK The whole of the NRTS is controlled from a series of regional control centres, which themselves are linked to a central hub in the West Midlands. The system is operated and monitored using bespoke computer software applications running on large capacity servers. Within the central hub there is a Network Operations Centre (NOC), which has access to a number of powerful server based applications, including asset management, i.e. the ability to interrogate the network to find out exactly what is installed at each transmission station or node. The NOC can remotely operate the telecommunications equipment, matrix signs, traffic cameras, collect data, monitor fault & security alarms and a number of other operational activities. 3.3 TRANSMISSION CABINET CONTENTS The actual equipment in each cabinet will depend upon the type and number of roadside services connected to it, and although there is a generic list, each cabinet can have an individual configuration. These cabinets are known as Transmission Cabinets (TC), T-cabs or Integrated Active Traffic Management cabinets (IATMg). IATMg cabinets are used where schemes exists for the controlled use of the hard shoulder. Document Number Version Version Date Ref / Project No: Page. JDL /05/2010 NRTS - UMS 4 of 8

Typical equipment includes video modems, not dissimilar to home broadband routers, remote alarm units to monitor equipment and report faults to the NOC (like domestic burglar alarms), and telecommunications multiplexers to connect everything together and drive the data around the network. Telecom multiplexers are specialist small rack-mounted data transmission computers. All equipment is of a constant and predictable electrical load, consume low energy levels and can be considered similar to home broadband routers, alarms or PCs. All telecommunications equipment selected for deployment on the NRTS network has been designed by recognised development and test houses; is available to purchase internationally and has been approved by the Highways Agency in Alcatel-Lucent s reference network. At Section 2 of this document, a series of WebLinks have been identified leading to the designers and suppliers of all equipment deployed in NRTS roadside cabinets. 3.4 HOW THE EQUIPMENT IS POWERED It is a convention throughout the telecom industry that equipment is capable of being supplied by a safe DC voltage (normally 48V). This also allows the use of battery backup systems and Uninterruptible Power Supplies (UPS), for continuation of service in case of AC power failure (mains and/or generator). The very nature of considering battery backup means that the selection and use of low power consumption equipment has obvious advantages. The for IATM-g cabinets, the only piece of telecommunications equipment connected to the single phase AC supply is the AC to DC rectifier. This rectifier supplies all active telecommunications equipment in the cabinet. This is a switched-mode power supply which converts the incoming AC supply into a stable 48V DC output. Switched-mode power supplies have a high efficiency rating of around 85 to 91%. This means that when the unit supplies the connected equipment, approximately 10% to 16% of the total power consumed, is within the rectifier itself. The rectifiers contain electronic circuitry to provide a stable DC output (within an AC input tolerance) and to compensate for either capacitive or inductive loads to ensure that the Power Factor value remains resistive, i.e. within 0.01 of Unity (Power Factor of 0.99 to 1.0).

However, some items are located within shared ownership cabinets and may be unmetered. The equipment concerned is located in either Active Traffic Management cabinets or roadside 600-cabs. 4.1 POWER CONSUMPTION MEASUREMENTS Alcatel-Lucent has established power consumption figures for all items of equipment within the network, submitted checklists and manufacturer s data to Elexon, however further evidence is required by the UMSUG committee. So, physical test result documentation is being sought (as opposed to technical handbooks and declared data specification sheets), along with further copies of ISO9001 certification for each design house. 4.2 UNMETERED SUPPLY CALCULATION In order to give an accurate estimate of electrical power consumed by an individual transmission node, the method proposed is to add the absolute values for all individual items within any node, then add 25% to the cumulative total (for worse-case rectifier inefficiency). Diagrams explaining the buildingblock approach have been included. There are 11 different active equipment types in the network, from 7 designers, so by applying for a Charge Code for each item, the total figure for any Transmission Cabinet, anywhere in the country can be quickly and simply identified.
