42、equired and optional for mobile stations and 4 BS/MSCs. 5 1.2 Terms 6 AT Command Set. Command set interface between data terminal equipment (DTE) and 7 data circuit terminating equipment (DCE). 8 Base Station. A station in the Domestic Public Cellular Radio Telecommunications 9 Service, other than a
43、 mobile station, used for communicating with mobile stations. 10 Depending upon the context, the term base station may refer to a cell, a sector within a 11 cell, an MSC, an IWF, or other part of the cellular system. 12 BS. See base station. 13 Data Circuit-Terminating Equipment (DCE). A DCE connect
44、s a TE2 to the PSTN. A 14 typical DCE would be a V-series modem. For Group-3 Fax Service, the DCE and its 15 associated TE2 are often combined into a single Group-3 fax machine. 16 Digital Facsimile. That form of facsimile in which densities of the original are sampled 17 and quantified as a digital
45、 signal for processing, transmission, or storage. 18 Error Correction Mode (ECM). A mode of operation for T.30 fax service providing end-to-19 end reliable data transport. 20 Facsimile. The process by which a document is scanned, converted into the electrical 21 signals, transmitted, and recorded or
46、 displayed as a copy of the original. 22 Fax. An abbreviation for facsimile. 23 Group-3. Digital Facsimile equipment per CCITT Recommendation T.4. 24 Interworking Function (IWF). An IWF provides the functions needed for terminal 25 equipment connected to a mobile termination to inter-work with termi
47、nal equipment 26 connected to the PSTN. A physical implementation may include a pool of modems. 27 Mobile Station. A station in the Domestic Public Cellular Radio Telecommunications 28 Service intended to be used while in motion or during halts at unspecified points. Mobile 29 stations include porta
48、ble units (e.g., hand-held personal units) and units installed in 30 vehicles. 31 Mobile Termination 2 (MT2). An MT2 provides a non-ISDN (Rm) user interface, e.g., 32 CCITT V series or CCITT X series. 33 Terminal Equipment 2 (TE2). A TE2 is a data terminal device that has a non-ISDN user-34 network
49、interface, e.g., CCITT V series or CCITT X series. 35 TIA-707.03-B 1-2 1.3 References 1 ANSI X3.4-1986 Coded Character Set 7-Bit American National Standard Code for 2 Information Interchange, 1992. 3 EIA/TIA-232-F Interface Between DTE and DCE Employing Serial Binary Data 4 Interchange. 5 EIA/TIA-592 Asynchronous Facsimile DCE control Standard - Service Class 2.0. 6 EIA/TIA-602 Serial Asynchronous Automatic Dialing and Control. 7 EIA/TIA-605 Facsimile DCE-DTE Packet Protocol Standard. 8 EIA/TIA-615 Extensions to Serial Asynchronous Automatic Dialing and Control. 9 T.4 Compression/deco
