SCOPE 1.1

25、GENERAL This Standard is applicable to the interconnection of data terminating equipment (DTE) and data circuit-terminating equipment (DCE) employing serial binary data interchange where a minimal number of control and information circuits are required. It defines: Section i - Scope Section 2 - Inte

26、rface Mechanical Characteristics Section 3 - Functional Description of the Interchange Circuits The electrical characteristics applicable to this interface can be found in AMERICAN NATIONAL STANDARD ANSI/EIA/TIA-562. 1.2 CONNECTION When used in conjunction with the above mentioned electrical charact

27、eristics standard, this Standard applies where equipment on one side of the DTE/DCE interface is intended for connection directly to the other side without additional technical considerations. 1.3 BIT SEQUENCES This Standard applies to data communication systems where data is bit serialized by the D

28、TE and the DCE and places no restrictions on the arrangement or the sequence of bits. 1.4 DATA SIGNALING RATES This Standard is applicable for use at data signaling rates at or below 38.4 kbit/s. Equipments complying with this Standard, however, need not operate over this entire signaling range. The

29、y may be designed to operate over a more narrow range as appropriate for the specific application. 1.5 NON-SYNCHRONOUS COMMUNICATION This Standard applies to non-synchronous serial binary data communication systems. 1.6 CLASSES OF SERVICE This Standard applies to duplex switched, non-switched, dedic

30、ated, leased or private line service, either tw+wire or four-wire.

The operation of this circuit shall not be disabled by an OFF condition on Circuit 108/2 (DTE Ready). The DTE may decline to answer a call by not placing an ON condition on Circuit 108/2 in resp

36、r of data on Circuit 104 (Received Data) when an intermediate function such as error control is being used in the DCE. The ON condition on Circuit 133 indicates that the DTE is capable of receiving data. The OFF condition indicates that the DTE is not capable of receiving data and causes the DCE, or

37、 the intermediate function, to retain the data. in some DCEs the OFF condition on Circuit 133 may also cause a signal to be transmitted to the distant DCE causing an OFF condition to be placed on Circuit 106 (Clear to Send) extending the flow control to the distant DTE.
