Data transmission is performed over a 100-m cable with two active interfering pairs with data retiming using recovered clock. The transmission system is based on modified duobinary modulation. A solution is presented to one of the problems which must be solved in order to send fiber distributed data interface (FDDI) signals over unshielded twisted pairs. The results indicate that FDDI may operate on this medium given a suitable mechanism for multiplexing the full data rate between two separate signal paths. The multiplexing circuitry represents an area where additional study is needed.<<ETX>>","PeriodicalId":122950,"journal":{"name":"[1990] Proceedings. 15th Conference on Local Computer Networks","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133542982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It uses low-level time-division multiple access (TDMA) that permits division of the bandwidth into bands of 25 or 50 Mb/s capacity. These operate independently and may carry either Ethernet/802.3 frames or transparent T1 traffic. The system is examined in the context of integrated services networks, since it provides both packet-based and fixed-bandwidth services over a ring circumference ranging up to 100 miles. As such it is a precursor to metropolitan area networks that are now emerging. Applications and lessons learned are presented.<<ETX>>","PeriodicalId":122950,"journal":{"name":"[1990] Proceedings. 15th Conference on Local Computer Networks","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131382305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This redundancy may be used to increase the reliability of the network. These network configurations include using dual attachment stations in the dual ring, invoking the hold policy, using concentrator trees and using dual homing in the concentrator tree. The reliability of these configurations is examined and compared with network configurations without redundancy. The results show that the dual ring is able to withstand single faults, but not multiple faults. Other configuration options must be used to withstand multiple faults. The hold policy does not significantly increase the fault tolerance of FDDI. There are a number of useful configuration options in FDDI that allow redundancy. Depending upon the required level of robustness, FDDI configurations are available to meet the requirements.<<ETX>>","PeriodicalId":122950,"journal":{"name":"[1990] Proceedings. 15th Conference on Local Computer Networks","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133571241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
