(A subscriber is responsible for thepayment of charges due to that service provider.)the common name for all the radio equipment atone and the same place serving one or more users.(See also “station”).A service which modifies or supplements a basictelecommunication service. Consequently, it can notbe offered to a customer as a standalone service,rather, it must be offered together with or inassociation with a basic telecommunication service.The same supplementary service may be common toa number of telecommunication services.The cell rate which could be sustained for a certainlength of time.Rec.

Specifically, UBRdoes not include thenotion of a per-connection negotiated bandwidth.No numerical commitmentsare made with respect to the cell loss ratioexperienced by a UBRconnection, or as to the cell transfer delayexperienced by cells on theconnection.-34-ATM ForumBased on ITU-T Rec.I.113Recs.
