Smds - switched multimegabit data service, английский
A public network service that will enable customers to send packets between lans at either t-1 or t-3 rates. switched multimegabit data service is offered by public network providers and is a connectionless (i.e., datagram) service. it will enable customers to exchange packets between sites at t1, t3 at potentially higher rates. this lan-like service will be offered by local exchange carriers and will initially be available only within selected metropolitan areas. a typical smda customer will have a wide-area communications device - i.e., a router - connected to a campus lan or backbone, which interface through a subscriber line to the local telco central office. the communication between the customer premises device (e.g., the router) and the telco will adhere to a protocol called subscriber interface protocol (sip). this protocol has three levels, only two of which are standardized levels 1 and 2 are fashioned from the ieee 802.6 mac standard for metropolitan area networking, which is called the distributed queued dual bus (dqdb) protocol. the third layer was promulgated by bellcore in one of its technical advisories. the smds service will support both t1 and t3 access from the user`s router to the local exchange carrier`s central office. smds is considered by the regional bell operating companies (rbocs) to be their first broadband service, and it will eventually be incorporate as a service offering for broadband isdn (bisdn) family of services in the late 1990s.
