Ta ble 4. 1 Issues related link vendor selection Issue Consideration Multiple vendors in corresponding radius Description every vendor that already has a link running in nearby location should not be given priority. exertion to provide the link to another vendor which has no or less links running in that area. Introducing multiple vendors will ensure maximum uptime for that area. Redundant backbone for Intercity Links distribute vendors that have different backbone for intercity connectivity.This will increase uptime incase of intercity backbone fails. Shorter Last mile connectivity Try to select vendors that will be able to provide last mile connectivity with shorter cable distance. As long-dated cables suffer from higher down time and require more maintenance. Licensed Radio Frequency Tower Height for Radio Links This will ensure better service quality and uptime. Identify vendors that will be able to establish a radio link with shorter tower. One time installation lade increase s as tower height increases. Longer tower needs more maintenance cost. Service QualityVendors with poor service quality should not be considered even though they have met all other requirements. Support Personnel Select vendors that have dedicated support personnel for remote locations. Also count reply time for all previous downtime. Balance of Distribution In order to ensure maximum uptime it is all-important(a) that we balance the distribution among the vendors. This will decrease the overall downtime. Local Loop Avoid same type of media for Last mile connectivity. Avoid any Point-To-Point Radio equipments at Lat mile. 21 4. 3 Network maintenance Following process follows for the network maintenance for link troubleshoot.Fig- 4. 2 Network Maintenance flowchart 4. 4 Link monitoring & maintenance Link Monitoring and maintenance works in two different ways. 4. 4. 1 Branch Link monitoring & maintenance Fig- 4. 3 Branch Link monitoring & maintenance flowchart 4. 4. 2 ATM link monit oring & maintenance Fig- 4. 4 ATM Link monitoring & maintenance flowchart 22 4. 5 Link troubleshoot checklist 4. 5. 1 Radio Link Fig- 4. 5 Radio Link Troubleshooting Process 4. 5. 2 Fiber Link Fig- 4. 6 Fiber Link Troubleshooting Process 4. 6 Remote access policy Fig- 4. 7 Remote Access Policy Process CHAPTER atomic number 23 Wi-Fi AND INTERNET CONNECTIVITY 5.

SWIFT also markets software and services to financial institutions, much of it for use on the SWIFTNet Network, and ISO 9362 bank identifier codes (BICs) are popularly known as SWIFT codes.The majority of international interbank messages use the SWIFT network. As of September 2010, SWIFT linked more than 9,000 financial institutions in 209 countries and territories, who were exchanging an intermediate of over 15 million messages per day. SWIFT transports financial messages in a highly secure way, but does not hold accounts for its members and does not perform any form of clearing or settlement. SWIFT does not facilitate funds transfer, rather, it sends payment orders, which must be settled via correspondent accounts that the institutions have with each other.Each financi al institution, to exchange banking transactions, must have a banking relationship by either being a bank or affiliating itself with one (or more) so as to enjoy those particular business features. 66 8. 2. 1 BRAC Bank Swift Network Diagram Fig-8. 37 Swift Network Diagram 8. 2. 2 SWIFT Infrastructure Overview A typical SWIFT customer environment consists of a combination of individual components that interact with each other to provide communicate services.

Working with a leading business organization was a disused chance for me. I really appreciate the way I have been guided through this internship program with BRAC BANK LIMITED. Beginning from t he opportunity to take the time I needed to refresh and expand my knowledge in several issues concerning System Administration. Over a somehow protected period where I could discover and learn to value my new working environment, and in the long run earned the confidence to deal with assignments myself. It is through them that I did enjoy my work every day.Having a rare opportunity to use the knowledge and skills that I had acquired, I learned how to handle critical network problems and got the new ideas. It was a great experience to work with networking devices practically and to troubleshoot different problems.
