ABOUT DELHI METRO RAIL CORPORATION Planning for the metro started in 1984, when the Delhi Development Authority and the Urban Arts Commission came up with a proposal for developing a multi-modal transport system for the city. The Government of India and the Government of Delhi jointly set up the Delhi Metro Rail Corporation (DMRC) in 1995.Construction started in 1998, and     

The first section, on the Red Line, opened in 2002, Followed by the Yellow Line in 2004, The Blue Line in 2005, its branch line in 2009, The Green and Violet Lines in 2010 and The Delhi Airport Metro Express in 2011.

A company under the name DMRC was registered on 30.05.1995 under the companies act for construction and operation of the metro project.The Government of

India and the Government of Delhi jointly set up a company called the Delhi Metro Rail Corporation (DMRC) on March 5, 1995 with E. Sreedharan as the managing director. It started functioning in November, 1997. It appointed General consultant in August, 1998 to assist them for implementation of the project. It is having 142 stations in the Rail corridor and 35 stations in the Metro corridor (underground). It has a combination

of elevated, at-grade and underground lines and uses both broad gauge and standard gauge rolling stock. The Delhi Metro Rail Corporation has been certified by the United Nations as the first metro rail and rail-based system in the world to get “carbon credits for reducing greenhouse gas emissions” Delhi Metro brought a revolutionary change in the city transport. It has also reduced the travel time. Also the pollution level is reduced to about 50%. A large number of commuters are having a lot of convenience in reaching their desired destination in the required time.

Dr. E. Sreedharan handed over charge as MD, DMRC to Shri Mangu Singh on 31 December 2011.

TELECOMMUNICATION DEPARTMANT It is the department of DMRC, which deals with the protection, supervision and operation of the train. In short it the department that manages the metro traffic on the rails. Transmission of information is possible through co-axial cables, wireless media, fibre optics. Communication at a distance by electronics transmission of impulses, as by telegraph, cable, telephone, radio, or television constitutes telecommunication.

Telecommunication department consists of following systems

Fiber Optics Transmission system(FOTS) It is the transmission system that uses optical fiber as communication media. Thus optical fiber communication is the method of transmitting information through optical fibers. FOTS can be termed as the backbone of DMRC telecommunication network. Fiber optics eases up the data and voice communication or access to various systems at different stations. This network is based on fiber optical cables on both sides of the track. The number of fibers is determined in order to comply with redundancy. The fiber is redundant for security and protection. In case of fiber optic failure, communication can take place via spare fiber while the fiber that is down may be fixed. FOTS is further differently prescribed in following ways.

SDH

MUX NETWORKS Synchronous Digital Hierarchy(SDH) Synchronous Digital Hierarchy (SDH) are standardized multiplexing protocols that transfer multiple digital bit streams over optical fiber using lasers or highly coherent light from lightemitting diodes (LEDs). At low transmission rates data can also be transferred via an electrical interface. The method was developed to replace the Plesiochronous Digital Hierarchy (PDH) system for transporting large amounts of telephone calls and data traffic over the same fiber without synchronization problems The STM-1 (Synchronous Transport Module, level 1) frame is the basic transmission format for SDH—the first level of the synchronous digital hierarchy. The STM-1 frame is transmitted in exactly 125 µs, therefore, there are 8,000 frames per second on a 155.52 Mbit/s OC-3 fiber-optic circuit. The section overhead (SOH) of a STM-1 signal is divided into two parts: the regenerator section overhead (RSOH) and the multiplex section overhead (MSOH).

9



The overheads contain information from the transmission system itself, which is used for a wide range of management functions, such as monitoring transmission quality, detecting failures, managing alarms, data communication channels, service channels, etc.

10



11



In SDH, information is transferred through optical fiber. Through this technology we are able to transmit data in terabytes using wavelength 1310 nm. There is no need to demultiplex whole information coming from side by stations. Information to side by stations is passed using STM-4 (Synchronized Transport Module) at 622.08 Mbps. 4 STM1 multiplexed in TDM (Time Division Multiplexing) forms STM-4. In this technology repeaters are required at comparatively larger distances Formation of E1 channel 0

E1 is the tributary signal for SDH to work. 256 such data packets give 65536 bps, approx. 64 kbps. 32 time slots of 64 kbps give E1 signal transmitting @ 2.048Mbps. E1 is bi-directional signal Out of these 32 channels 30 are used as voice channel while 2 are used for control and signaling information.

MULTIPLEXER(MUX) In telecommunications and computer networks, multiplexing (also known as muxing) is a method by which multiple analog message signals or digital data streams are combined into one signal over a shared medium. The multiplexed signal is transmitted over a communication channel, which may be a physical transmission medium. The multiplexing divides the capacity of the high-level communication channel into several low-level logical channels, one for each message signal or data stream to be transferred. A device that performs the multiplexing is called a multiplexer (MUX). In DMRC, the Time Division Multiplexing is used. The Time-division multiplexing (TDM) is a digital technology. TDM involves sequencing groups of a few bits or bytes from each individual input stream, one after the other, and in such a way that they can be associated with the appropriate receive. Consider an application requiring four terminals at an airport to reach a central computer. Each terminal communicated at 2400 bit/s, so rather than acquire four individual circuits to carry such a low-speed transmission; the airline has installed a pair of multiplexers. A pair of 9600 bit/s modems and one dedicated analog communications circuit from the airport ticket desk back to the airline data center are also installed . If done sufficiently quickly, the receiving devices will not detect that some of the circuit time was used to serve another logical communication path.

13



If data rate is less than 64 Mbps then, it is termed as sub-rate. If data rate is more than 64 Mbps then it is termed as super rate. Access-MUX is used for systems requiring transfer rate below 2.048 Mbps. It multiplex the data from the systems operating at the data rates lower than 2 Mbps into E1 lines. Since no single node will be able to use all the bandwidth therefore, all the data i.e. audio and video signals are multiplexed in order to make maximum use of available bandwidth.

14



Optical Distribution Frame (ODF) GSS and FPS together forms ODF (Optical Distribution Frame). At each node (or station), optical fiber cables are terminated in the GSS (Generic Splicing Self) and are distributed to the system through FPS (Fiber Patching Shelf). From the FPS patch cords, both ends have connectors for connection, are sent to the SDH where apart from being converted to electrical signal, the signals required at the particular node dropped (or extracted) and multiplexed into E1 lines at 2.048 Mbps which are terminated at DDF (Digital Distribution Frame). The DDF basically provides a flexible way of connecting equipment side to cable side. From the DDF the system working at 2 Mbps rate is directly provided the connections with required number of E1 lines. The systems working with lower rates than 2 Mbps access the network through FMX. The FMX demultiplexes the E1 lines coming from DDF to the lines at the lower rates for use of various systems. There are two GSS, one for up (in Depot direction) and other for down (opposite to Depot). There are 48 trays in each GSS. All fibers coming from and going to adjacent stations are passing through GSS. Fibers needed at particular station are connected to FPS in zero dB connector (0.3dB loss) through pigtail cords, connector at one end only. These fibers are then passed to SDH. And fibers not needed at particular station are spliced through. Splicing is a technique for joining together individual fiber or optical cable sections to forms continuous lines for these long distant links. Splicing can be done in two ways:  

Mechanical Splices: This aligns the axis of the two fibers to be joint and physically hold them together. Fusion Splices: This is accomplished by applying localized heating (i.e. by electric arc or flame) at the interface between two butted, pre-aligned fiber ends, causing them to soften and fuse together.

In DMRC fusion splicing is used. Splicing loss is around 0.1dB.

15



NETWORKING It consists of two or more computers that communicates and share their resources. Three types of network are:

1. LAN (Local Area Network): A LAN connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN. LAN are typically owned, controlled and managed by a single person or organization. They also use certain specific connectivity technologies, primarily Ethernet and Token ring.

2. WAN: As the term implies Wide Area Network spans a large physical distance. WAN is geographically dispersed collection of LANs. A network device is called a router connects LAN and WAN. In IP networking, router maintains both a LAN address and a WAN address. WAN differs from LAN in most of the ways. Like the Internet, most WAN are not owned by one organization but rather exist under collective or distributed ownership and management. WANs use technology like ATM (Asynchronous Transfer Mode), frame relay X.25 for connectivity.

3. MAN: It implies Metropolitan Area Network. It is used to encompass larger areas, usually that of entire city.

OSI Layers (Open System Interconnection): OSI is the name for the set of standards for communicating among computers. The primary purpose of OSI standards is to serve the structural guideline for exchanging information between computers, workstations and networks.

TELEPHONE EXCHANGE/EPABX EPABX is stands for Electronics Private Automatic Branch Exchange. For purpose of planting communication link between different stations, DMRC has its self-sustained telephone exchange. This system works on -48 V DC from SMPS. Data is processed at a rate of 64k bps. EPABX System at OCC: Telephone system shall interface to the radio system to enable radio users to initiate and receive calls to/ from EPABX extension or to MTNL or TATA INDICOM telephones. Centralized Digital Recording System: The telephone system is equipped with a CDRS for recording of designed lines, emergency PAS announcements and designated conversion system. Network Management System: The telephone network including EPABX and DLTC system is monitored, supervised and controlled by a NMS. EPABX rack is divided in two shelves:  

Shelf 0 Shelf 1

These shelves can be extended according to requirements. Shelf 0 has CPU, which is comprised of following cards:  2 Power cards: This card distributes power to whole rack. One is active and another is redundant.  SF2X8 card: This card provides LAN ports for monitoring of EPABX at other stations.  2 DXCXL cards: These are CPU cards used for networking purposes. One card is active and other is not in use.  ADP: Administrative Data Processor.

RADIO/ EBTS EBTS stands for enhanced base transceiver system. EBTS is another important equipment of DMRC. This system enables the access to the radio services while roaming within the radio coverage. EBTS provides all the remote site functionality. EBTS has all features of mobile communication and broadcasting of any information which are not available with the telephone system. The radio communications system is designed for providing system-wide voice and data communication to support the operation and maintenance for Delhi Mass Rapid Transport System (DMRTS). It provides two-way voice and data radio communication throughout the operational areas of DMRTS, to provide efficient and effective train radio dispatching operation for Barakhambha OCC. One more plus point of this system is that it adds to the level of redundancy to the communication network of DMRC if FOTS (Fiber Optical Transmission system) breaks down as whole communication between the source and destination does not takes place through FOTS. This system transfers data at a rate of 128 kbps. DMRC uses MOTOROLA DIMETRA (Digital Motorola European Trunk Radio) which is sophisticated digital radio equipment having full benefit of TETRA (Terrestrial Trunked Radio) standards and range is 380-400MHz. Receiving range is 380-390 MHz and transmitting range is 390-400MHz. This system works on -48 V DC supply from SMPS. Dimetra IP is Motorola’s TETRA-compliant digital radio system. The system provides services to three groups of users: 

Radio Users – the mobile users in the system that can roam throughout the radio coverage area provided by the system. The radio users access the system services using Mobile Stations that communicate with the Base Stations in the infrastructure using the TETRA air-interface protocol.



Controllers – users at fixed locations that have access to advanced features and facilities provided by the system. These features enable Controllers to efficiently communicate with and manage fleets of mobile users.



Network Managers – responsible for managing and maintaining the Dimetra IP system. The system provides numerous applications that allow the network managers to efficiently manage the system.

Wireless transmission has the advantage of not having to install physical connections at every point, but is limited to Line of Sight (LOS). EBTS sites are place 25 to 75 miles apart. Thus, DMRC has total 15 EBTS sites out of which 9 EBTS sites are at line3. EBTS sites are similar to an antenna except for one thing i.e., it requires GPS synchronization signal through the GPS. Underground areas can not have EBTS sites hence, Leaky Co-axial Cables (LCX) are used, with Bidirectional Antenna (BDA). TETRA Trunking: A method of traffic channel organization where a traffic channel is allocated for each call transaction. Trunking facility provides a pooling of all radio channels which are then allocated on demand to individual users.

22



The radio users access the systems services via the Mobile Stations. The Base Stations (BSs) provide the radio interface that allows the Mobile Stations to communicate with the system infrastructure when moving within the system’s radio coverage area. The TETRA radio system is a single zone system. All the BTS are controlled by two Zone Controllers in redundant configuration. During operation, only one Zone Controller is active. The other Zone Controller is in standby mode and not taking any load. There is also additional equipment associated with the Zone Controllers. Each BTS is connected to a Mobile Switching Office (MSO) and two Zone Controllers on a redundant configuration and associated equipment are located at the MSO. The Controllers access the system services via Communication Consoles that are located at the OCC and the Control Rooms in Stations and Depots, or at a remote control sites such as the Stations and Depots. Each remote control site also has some further equipment in addition to the Dispatch Consoles. Each base station consists of base radios. Each base radios are assigned a frequency which is the physical channel. This physical channel is divided into four logical channels using TDMA. The first BR would normally contain the control channel, a packet data channel and two traffic channels. The next BRs are normally assigned with four traffic channels each. The base station is linked to the MSO using E1 via FOTS. This E1 link transports all information coming from and going to the base station including alarm information, audio, data and control information

Types of Modes of Communication: There are two types of modes of communication in DMRC network: 

Trunked mode operation:

This operation consists of four operation modes: a) Group mode- It is a half duplex communication mode in which many user can communicate with each other by selecting a common talk group. The operation is as follows: i) Select a talk group to communicate. ii) Press PTT (Press to Talk) to speak. iii) Release PTT to listen. b) Private mode- It is a half duplex communication mode in which two users can communicate with each other privately without interfering a talk group. The operation is as follows:  Select a private mode by using mode key.  Dial private ID.  Press PTT and release. A ring will be heard.  Press PTT to speak.  Release PTT to listen. c) Phone mode- It is a full duplex communication in which radio user can talk to phone number used within DMRC or external network connected to DMRC. It can also communicate in reverse direction, i.e., from phone to radio. The operation is as follows:  Select the phone mode by using mode key.  Dial phone number.  Press call/cancel key.  Talk when call established.  Press call/cancel key to end call. d) Emergency mode-In emergency mode, TETRA in emergency mode has the highest priority and every TETRA belonging to that group can listen the information.

25



Base Station The base station equipment is often known as a Base Transceiver System (BTS). Each base station provides radio coverage in a specific geographic area known as a cell and as the radio users roam around the systems coverage area, they move from one cell to another. The radio users use MSs that communicate with the BTSs using the TETRA air-interface protocol. This protocol contains mechanisms to allow the MSs to select the most appropriate BS for communication at any location without any intervention from the radio user. MTS4 has two E1 interfaces for easy ring configuration to promote high redundancy. With ring configuration failure on one side of the ring will not affect the working of any base station. MTS4 will be link to MSO using ring configuration. Ring 1 Ring 2

The standard BTS will equip with 2 carriers (TX) Base station serving OCC and also for two (2) of the underground station will be 4 carrier (TX) The BTS will be installed in the TER room at the station to provide the area coverage throughout the DMRTS network. The basic configuration will consist of the following components:  Tetra Site Controller (TSC)  Base Radios (BR)  Radio Frequency Distribution System (RFDS)  Power Supply Unit Base Radio (BR) The Base Radio (BR) provides a high powered RF interface. It can provide up to 25 watts of RF power to the antenna system after RFDS losses. Each BR utilizes TDMA technology to provide 4 channels on a 25 kHz carrier. A single MTS 4 cabinet may hold up to four BRs. The BR also incorporates diversity reception for increased talk-back range, performance and reliability. A combined three-receiver board is provided with each BR to allow for 2 or 3 branch antenna diversity. Site Controller (SC) The Site Controller (SC) is a PowerPC based computer. It communicates with the MSO components over the E1 interface and controls the operation of the Base Radios. The SC also contains a time and frequency reference module. The module includes a high stability oscillator to provide the frequency reference and GPS receiver to provide the timing reference. Radio Frequency Distribution System (RFDS) The Radio Frequency Distribution System (RFDS) uses hybrid combiner to combine the outputs of the Base Radios into a one transmits antenna connection. The RFDS also uses a receiver multicoupler to distribute the signal from each of the receive antenna connections to each of the Base Radios. Power Supply Unit (PSU) The Power Supply Unit provides power to all of the units within the MTS 4. The PSU accepts 220 V AC or -48V DC inputs. In addition the PSU also provides the facility to charge an external battery supply and to revert to this power source in the event of input power failure.

Redundancy The operation of a Megaplex system depends on three critical modules: the power supply, the main link module, and the CL module. A failure in any one of these modules could disable the whole system, whereas a failure in an I/O module affects only a small part of the system, and can be generally overcome by using alternate routes, putting unused capacity into service, etc. The Megaplex system is designed to automatically put a redundant module in service in case the corresponding module fails, thereby ensuring continuous system operation in the event of any single module failure.

GATES Equipment which controls the access of patrons from free area to paid area & vice versa according to business rules that device, which demarcates the paid & unpaid area, is known as a Gate. There are two types of gates:  ENTRY ONLY  EXIT ONLY  BIDIRECTIONAL/ HYBRID ENTRY ONLY This gate is only used for the entry. From this gate passenger can’t exit or leave the concourse EXIT ONLY This gate is only used for the Exit. From this gate passenger can’t take entry. HYBRID/BIDIRECTINAL This type of gate is used for physically challenged people. It is wider than the simple gate and is appropriate for any standard wheel chair to pass through.

34



TOKENS These are the advanced tickets used in DMRC. It is used for Travelling or Entry in the Metro Stations. There are two types of tickets by which we can do our journey:  Contact less smart card  Contact less smart token Contact less smart token: It is a coin like device, which has a chip in which read & write operation can be performed. It also consists of a coil, which is charged through electromagnetic induction on interaction with the gate. A special machine known as R/W module is used for the R/W operation in token.

Contact less smart card: The external structure of CSC is like an ATM card or a credit card, in which R/W & processing operation take place. It has an electromagnetic coil at its edges, which is used for taking power through radio waves, which is in micro volts.

Passenger Information Display System (PIDS) The aim of the system is to display and announce traffic information and other convenient information along the station and various platform areas .The PIDS allows the data input, transmission and diffusion of information concerning the movements of trains in real time to all station users and the same for the application in main center using Ultra Bright LED Display Panels .The system has capability to control virtually unlimited no. of stations which can be done by the configuration of the network design . The PIDS designed for the DMRC’s network has several functions such as displaying train scheduling information and data related to train circulation like arrival and departure time. The system is divided into two main parts: The Operational Control Center: this refers to all the equipments installed in the OCC. the details are :  Server  Assistant to Chief Controller PIDS /PAS workstation  PIDS Backup Control Panel The Station System: this refers to all the equipments installed in the terminal stations. the details are :  WorkStation



Ultra Bright LED Panels

Central Passenger Information System: it is located at OCC and includes the system server and the Assistant Chief Controller Workstation. The Remote Passenger Information System: It is located at each station and includes the station server, the station MMI (Man Machine Interface) position and Ultra Bright LED Panels. The station server located in each station receives periodic data at location information from the OCC server. In this manner it manages and controls the local Ultra Bright LED Panels.

38



Passenger Address System (PAS) It is one of the systems that create a user friendly ambience in the DMRC computer services and it plays a very important role as well. As of date this system receives information from the TIMS (management software) which is something similar to train timetable as per the present time it sends information to this system and the address is made. This is one of the reasons that a universal clock is required and that is the reason the network is incorporated with a master clock server. The scheme is such that the train driver has information about the timings and he has to see that the train reaches a particular station as per the time frame it has been allotted, which is similar to normal railways. The thing that is making it a little bit different from the railway is that this timetable is a static one and so fixed and is totally computerized while that in the railways is a dynamic one and it is user controlled.

PASSENGER INFORMATION DISPLAY SYSTEM/ PUBLIC ADDRESS SYSTEM(PIDS/PAS)

The main purpose of the PAS and PIDS is to transfer information to the passengers at concourses and platforms for notification of scheduled train arrivals and departures and some special messages such as emergency or evacuation messages. This system takes 3 phase AC power supply from ACDB (AC Distribution Box). Each station has two PIDS at each platform and 2 PIDS in concourse zone, so a total of 6 PIDS used.

SYSTEM RACK Public announcement system consists of several modules which can be joined individually and provide the opportunity to integrate external sources. It is expandable and upgradeable. It consists of:  DOM (Digital Output Module)  MSU (MAIN SWITCHING UNIT)  UIM (UNIVERSAL INTERFACE MODULE)  PA (POWER AMPLIFIER)  RMU (Remote Monitoring Unit)

DOM (Digital Output Module) This system converts digital to analog signals. The VARIODYN® D1 modules DOM4-8 and DOM4-24 are equipped with four independent audio channels, each one able to drive one 100V power amplifier and to provide two (DOM4-8) or six (DOM4-24) switched 100V loudspeaker lines. So PIDS/PAS has a total of 12 channels, four from every DOM. All power amplifiers are permanently supervised. In case of an error one or more backup amplifier (optional) can replace defective power amplifier units. Used loudspeaker lines are permanently supervised for short circuits, ground leakage, or circuit interruption. Faulty lines are disconnected if necessary. The built-in automatic volume control (AVC) feature permits permanent automatic volume adaptation of broadcasted sound to environmental sound levels for each of the four audio channels in real-time.

MSU (MAIN SWITCHING UNIT) It converts 3-phase AC supply to 110V DC. MSU unit distributes the mains power to all the components mounted in the rack. In addition the unit offers a socket for the connection of a laptop for local/network wide maintenance purposes. Each of the 3 phases can be loaded with up to 18A. The operating state is indicated with a green indicator. A front side 230V standard equipment socket and a RJ45 socket are available for the connection of a laptop PC to the VARIODYN® D1-Network; this connection enables the possibility to check PIDS/PAS system at other stations.

PA (POWER AMPLIFIER) Power Amplifier modules are equipped with two separate channels and 100V output transformers and are controlled and monitored by VARIODYN® D1 System modules DOM4-8 or DOM4-24. Features like electronic protection against thermal overload and short circuit as far as temperature controlled fans are integrated. Three types of amplifiers with different output power are available (2x200W, 2x300W or 2x500W).

2x500W Front

2x500W Back

RMU (Remote Monitoring Unit) This unit is used to monitor 10 channels remotely whether they are working properly or not. It also shows dB level of announcement. Servers: Each station has two servers, one in HOT mode (perform normal operation) and other in STANDBY mode. Both servers send status signal via RS-232 to watchdog/relay switch. If trigger signal is missing, the Switchover unit will switch to the other server within 15 seconds. STANDBY mode is more reliable than HOT mode because there is a high risk that both Servers may crash in some environmental conditions as both are performing the same task. There is a manual switch at the unit, watchdog changeover, so the Relays can be switched either to position 1 (normal closed contacts) or position 2 (normal open contacts) or to “AUTO” (Watchdog controlled). Switchover unit is USB powered from servers and the Display boards are controlled via RS485/RS422 serial lines, in case of failure it switches to other workstation. Whenever changeover occurs an alarm indication (alarm pop-up window and audio signal) is shown on the active MMI. Server 1 is provided with PAS card but in server 2 it has PAS card only in underground stations not at elevated stations.

43



Operation of PIDS/PAS Information about the train arrival is passed to OCC from interlocking station through track circuits having sync loop. Every information from OCC server is sent with address bit, so that, particular station for which information is sent, picks it up. Information sent will be in code form, about announcement or display should take place in zone specified. Display information goes directly to PIDS through bus-bar, but announcements from server goes to universal interface module (UIM) through DVA (Digital Voice Announcements) channel. UIM converts analog information to digital for use in amplifiers. DOM converts the analog signal back to digital. After amplification information goes through defined channels.

SCR (Station Control Room): DMRC has one SCR at each station. Two MMI workstations with digital call stations placed in SCR and controller in SCR manages the local PIDS/PAS system of that station.

MMI Application: MMI have remote access to the servers in TER. The Operator at SCR can initiate prerecorded messages or make live announcements from these MMI. The Operator at each platform can also make announcements from a digital call station provided per each PSB. The MMI is running on MMI PC workstation. First line contains DMRC name, Station name, Username, name of the function, time and date. The second line contains pull down menus for File, View and Help. The rest of the screen can be divided into 5 parts:  Function selection line: Selection of display and functions.  Station display: Different forms of station display with PIDS Display Board Content.  Function window: Different windows for different PAS/PIDS system function.  PA Input Status: Shows the in use status of PA sources.  Error Status: Shows the most recent Error/Alarm of PA/PIDS system / allows LIVE PA messages to selected PA zones.
