18、iation, PCCA STD-101, including the provisionally approved Annex F and Annex I. 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 com

19、mands for Wireless DCE used in Packet Data Networks. The commands were added as Annex D in the Table of Contents, and are defined in the body of the Annex, which has been added to this revision.

35、-TIA-678-A 1 1. SCOPE This standard is applicable to the interconnection of data terminal equipment (DTE) and data circuit-terminating equipment (DCE) employing serial binary data operation via the 100-series interchange circuits or data operation over equivalent logical circuits. This standard spec

36、ifies extensions to the protocol elements, procedures, and behaviors described in ANSI/TIA/EIA-602-1992 (TIA/EIA-602-A). These extensions are based on the “+” command prefix that is reserved by TIA/EIA-602-A for standardized extensions, and adhere to the extended command syntax conventions establish

37、ed by ITU-T V.250. This standard generalizes the protocol elements, procedures, and behaviors described in TIA/EIA-602-A, making them applicable to DCE which operate over arbitrary data networks. This standard defines the commands that the DTE may issue to: (2) Interrogate the capabilities of the DC

38、E, including determination of what data network types and associated network-specific AT command set extensions are supported by the DCE; (3) Select among supported data network types for subsequent DCE processing of automatic calling and automatic call answering functions; and, (4) Select among sup

39、ported 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 data network services and the D

40、CE protocol elements, procedures, and behaviors referenced in TIA/EIA-602-A (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. This standard establishes a mi

41、nimal DCE Common AT Command Set consisting of: (1) Those commands defined in TIA/EIA-602-A and 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 through Annexes

42、. 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 mode and i

43、n Reliable Transparent Character Stream mode, as selected by +WS45=0 or by +WS45=1.
