1 STATUS AND UPGRADATION PLAN OF RTH NEW DELHI AND TELECOMMUNICATION NETWORK OF IMD N.K.Pangasa Director RTH New Delhi

2 GTS Links with RTH New Delhi RTH NEW DELHI Tokyo IP-VPN Moscow IP-VPN Beijing IP-VPN Melbourne Soc(Int) Oman Soc(Int) Male Soc(Int) Jeddah 64Kbps Soc(IP) Karachi 64Kbps Soc(IP) Dhaka 64Kbps Soc(IP) Colombo Soc(Int) Cairo 100bauds Under testing for 64Kbps Tehran 75 bauds Ordered for 64Kbps Kathmandu 50 bauds Yangon 50 bauds Bangkok 200 bauds Ordered for 64Kbs

3 Recent Developments at RTH New Delhi Table Driven Code Form: RTH New Delhi is transmitting daily Synop (on test basis) and SATOB messages of Indian Region in BUFR Format (Developed by IMD) to Tokyo through GTS Digital Satellite Broadcast of IMD through Asia Star satellite has been changed to multicasting File naming server installed is providing data to users through TCP/IP Socket, , SMS and FTP in WMO File naming conventions. It has also feature of OCR (Optical Character Recognition) to extract information from imageries. GMDSS bulletin is also placed on IMD website in real time.

4 Proposed RTH Features High Availability (more than 99.9%) Cluster Mode Duplex Web, and FTP Conversion from CREX, BUFR, GRIB to ASCII and vice versa Audio visual Alarm for warning messages Message reception through PSTN/Dial- up and SMS Transmission of warnings through SMS to predefined numbers. File switching OCR base FAX transmission and reception Authentication server for Internet users Bilingual features (English and Hindi). Daily throughput of data GB. GUI base interface and web interface. Back

5 RTH, At New DelhiRTH AMSS At 6 locations (4 old +2 new)AMSS VSAT Network 64 kbps Terminal IVRS Data Terminal Data Terminal At 75 Observatories Interne t At 26 MCs Common People International Network Ongoing Modernization Projects of Telecom Division 64 kbps – 2 mbps Link PSTN/Dial-Up Link Mobile/SMS Link VSAT Link Internet Link for & FTP VPN Link Main Flow of Data ( At 26 Locations )

6 Data Terminal Features: The system will be PC (P-IV) based. The system can connect to Data Collecting Centres (64 kbps terminal) using PSTN/Dial-up link for submission and retrieval of data. It also supports transmission and reception of messages via GSM based GPRS or SMS. The system can transmit and receive messages via , FTP and FAX. The system has browser based GUI for data handling/manipulation, submit and retrieve meteorological messages. Back Data Terminal At Observatories Data Terminal Locations ( At 75 Observatories/Field Stations )

7 Proposed AMSS Features High Availability (more than 99.9%) Cluster Mode Duplex Web, and FTP Conversion from CREX, BUFR, GRIB to ASCII and vice versa WMO as well as AFTN switch Audio visual Alarm for warning messages Message reception through PSTN/Dial- up and SMS Transmission of warnings through SMS to predefined numbers. File switching OCR base FAX transmission and reception Authentication server for Internet users Bilingual features (English and Hindi) Daily throughput of data GB. GUI base interface and web interface. Back ( Existing 4 at Kolkata, Mumbal, Delhi and Chennai and 2 new at Guwahati and Nagpur )

9 64 Kbps Terminal Features: The system will be PC (P-IV) based. Standard TCP/IP based socket communication for transmission and reception of messages. Retrieval and submission of messages through PSTN/Dial-up network. Submission of messages through SMS. Transmission and reception of messages through in English and Hindi. Web Interface. GUI based module for submission and retrieval of data. Back 64 kbps terminal Locations ( At 27 Locations ) 64 kbps Terminal

10 IVRS Features: The system will receive WMO formatted messages and decode these messages to weather parameters for answering weather queries by public. The system shall interact with caller in English, Hindi and at least one Regional language of that place where it shall be installed. The system will work with all type of exchange used in DOT/MTNL/BSNL etc. including Mobiles. The system will operate round the clock with 99% uptime. The system shall have provision to transfer the call to the duty officer in case the caller query is not available in the database. No single point of failure. GUI based administration modules. Voice messages will be recorded by professionals. Back IVRS Locations ( At 26 Locations ) IVRS

11 Present Setup of IMD Communication * SINGLE PATH VIA GROUP OF NODES. * DELAY DUE TO MULTIPLE HOPS COVERAGE. * MODE OF COMMUNICATION: TP/TELEX/TELGRAMS/HFRT COSTLY. * OLD AND OBSOLETE TECHNOLOGY

12 Need for Modernization DEPT. OF TELECOM IS WITHDRAWING TP/TELEX LINKS AND HAS ALREADY WITHDRAWN FROM MANY PLACES. DATA THROUGH TELEGRAMS REACHING VERY LATE. HFRT (HIGH FREQUENCY RADIO TELEPHONY) IS OBSOLETE TECHNOLOGY AND WORLD WIDE BEING REPLACED WITH LATEST TECHNOLOGIES AVAILABLE LIKE SMS THROUGH MOBILE AND SERVICES. VPN IS LATEST TECHNOLOGY WITH ADVANTAGES OF CONNECTIVITY BETWEEN ANY TO ANY IN COMPARISON TO DEDICATED LINKS WHICH IS CONNECTIVITY BETWEEN ONLY TWO ASSIGNED LOCATIONS. VPN LINKS ARE SECURED AND COST EFFECTIVE LINKS. MOBILE DATA TERMINALS WITH ADDITIONAL DIAL UP MODEM IN BUILT UTILIZES DATA EXCHANGE THROUGH SMS, AND DIAL UP CONNECTION. SMS AND UTILIZES SIMULTANEOUS TRANSMISSION TO MULTI NODES THUS DATA AVAILABILITY AT AMSS AND RTH ARE VERY FAST. AT PRESENT IVRS SYSTEM IS AVAILABLE ONLY IN FOUR METROS. AS A PUBLIC WEATHER SERVICE IVRS SYSTEMS ARE REQUIRED TO BE AVAILABLE AT ALL MET CENTRES. AS PER WMO REQUIREMENTS RTH IS REQUIRED TO EXCHANGE BINARY DATA IN BINARY UNIVERSAL FORM (BUFR) FORMAT, IMAGERIES AND WEB PAGES WHICH ARE AT PRESENT NOT SUPPORTED BY OUR EXISTING SYSTEM. REQUIREMENT OF AMSS SYSTEM AT NAGPUR AND AMSS MODERNIZATION AT GUWAHATI.

13 1.SIMULTANEOUS EXCHANGE OF DATA WITH MULTIPLE NODES 2. REAL TIME DATA EXCHANGE. CATEGORY-I 85 OBSERVATORIES WITH MULTIPLE OBSERVATIONAL FACILITIES. CATEGORY-II 385 OBSERVATORIES WITH LIMITED OBSERVATIONAL FACILITIES. CATEGORY-III 26 REMOTE OBSERVATORIES IN MOUNTAIN, DESERT AND OTHER INACCESSIBLE AREAS.

14 Technology for modernization VPN (VIRTUAL PRIVATE NETWORK) LINKS. HIGH SPEED LINKS. SMS THROUGH MOBILE SERVICE. SERVICES. DIALUP CONNECTIVITY FOR DATA RETRIEVAL AND SUBMISSION VSAT LINKS AT COASTAL/DESERT AND MOUNTAIN AREAS. SATELLITE BASED DIGITAL DATA BROADCAST AND ITS RECEPTION. INTERACTIVE VOICE RESPONSE SYSTEM (IVRS) – A PUBLIC WEATHER SERVICE. DATA RECEPTION THROUGH WEB INGEST
