In data communication, data link is those parts of two data terminal equipments that are controlled by a protocol along with the(71) data circuit, which together enable data(72). So-called protocol means, in short, a set of rules that determines the behavior. of functional units in achieving communication.Data circuit, however, consists of a pair of(73) transmission channels that provides a means of two-way data transmission. Between data switching exchanges, the data circuit may or may not include data circuit-terminating equipment (DCE), depending on the type of(74) used at the data switching exchange. Between a data station and a data switching exchange or data concentrator, the data circuit includes the DCE at the data station end, and may include equipment(75) to a DCE at the data switching exchange or dam concentrator location.A．handshakingB．interconnectingC．linkageD．joining
