TIA-678-B FOREWORD (This Foreword is not part of the Standard) This Standard is based on the work of the Portable Computer and Communications Association, PCCA STD-101, including the provisionally approved Annex F and Annex I

21、. Annexes F and I are renumbered Annexes B and C respectively. Most of 5.2/STD-101, which is redundant with TIA/EIA-602-A or ITU-T V.250, has been removed. This Standard includes a new Annex D which defines PAD Control commands for Wireless DCE used in Packet Data Networks. The commands were added a

22、s Annex D in the Table of Contents, and are defined in the body of the Annex, which has been added to this revision. Appendix I has been modified to include summaries of the commands, and the Scope has been modified. Revision A of the Standard incorporates changes detailed in TIA/EIA-678-1 Addendum

23、1 to TIA/EIA-678. In addition, the references to ITU-T V.25ter have been replaced with references to ITU-T V.250. References to other standards have also been updated or replaced with the applicable reference. Revision B of the Standard changed all references to TIA/EIA-602-A to reference appropriat

24、e sections of ITU-T V.250. Many of the referenced sections of TIA/EIA-602-A no longer exist.

SCOPE This standard is applicable to the interconnection of data terminal equipment (DTE) and data circuit-terminating equipment (DCE) employing serial binary data

36、 operation via the 100-series interchange circuits or data operation over equivalent logical circuits. This standard specifies extensions to the protocol elements, procedures, and behaviors described in ITU-T V.250. These extensions are based on the “+” command prefix and adhere to the extended comm

37、and syntax conventions established by ITU-T V.250. This standard generalizes the protocol elements, procedures, and behaviors described in ITU-T V.250, making them applicable to DCE which operate over arbitrary data networks. This standard defines the commands that the DTE may issue to: (1) Interrog

38、ate the capabilities of the DCE, including determination of what data network types and associated network-specific AT command set extensions are supported by the DCE; (2) Select among supported data network types for subsequent DCE processing of automatic calling and automatic call answering functi

39、ons; and, (3) Select among supported DTE-DCE interface protocols. This standard defines the responses the DCE shall issue to those commands. Where possible, these commands and responses are taken from existing TIA standards. This standard establishes required mappings between manufacturer-specific d

40、ata network services and the DCE protocol elements, procedures, and behaviors referenced in ITU-T V.250 (e.g. ring, dial, answer, busy, on-line data state). This standard establishes conventions for interworking of network-specific AT command sets in DCE which support multiple data network types. Th

41、is standard establishes a minimal DCE Common AT Command Set consisting of: (1) Those commands defined in ITU-T V.250, and (2) Required extensions using the +W command prefix in accordance with ITU-T V.250. This standard establishes conventions for uniform extension of its own scope and content throu

42、gh Annexes. Annex D defines optional extensions to the protocol elements, procedures and behaviors defined in the original standard, based on +WS and +WC command prefixes reserved for standardized extensions. The parameters in Annex D only affect operation of the DCE in Transparent Character Stream

43、mode and in Reliable Transparent Character Stream mode, as selected by +WS45=0 or by +WS45=1. TIA-678-B 2 2.
