Bellcore is planning a release a second issue of TA-909. The two primary drivers for the planned re-issue of TA-909 are to improve existing requirements that may permit more cost-effective delivery of existing services and to provide initial requirements that enable upgrade of TR-909 systems for the transport of higher bandwidth services. The pending additions and changes that are currently being socialized within the industry, Bellcore and BCCs are outlined. Some of the key technical areas discussed include a more cost-effective platform for the delivery of existing telecommunications services, powering, the interrelationship between SONET (synchronous optical network), IDLC and FITL technologies, the changing transmission and operations environment impacting FITL system deployment, and higher bandwidth service capabilities and performance. The requirements evolution for existing telecommunications services is also discussed.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129692169","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}

There are different evolutionary routes which could be pursued to evolve current networks to this goal. One option is to use dedicated fiber feeders to active nodes, each serving a few hundred customers on a shared tree and branch coaxial network. The alternative is to puruse a more fiber intensive approach. The fiber intensive approach is compared to the fiber-coax approach within a telco environment, and the way in which the fiber approach could evolve is examined.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125480905","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}
