適用范圍：1 Recommendation F.200 lays down the provisions for the operation of the automatic international Teletex service. On the technical side, Recommendation T.60 specifies the requirements for international compatibility between Teletex terminals and Recommendation T.61 defines the character repertoire and coded character sets for the international Teletex service.2 Recommendation F.161 defines the rules to be followed in the Group 4 facsimile service. On the technical side, Recommendation T.5 specifies the requirements for Group 4 facsimile apparatus and Recommendation T.6 defines the Group 4 facsimile coding scheme and facsimile control functions.3 Recommendation T.73 defines the document interchange protocol which may be used when services other than basic Teletex are utilized; e.g. Group 4 facsimile, mixed-mode operation, etc.4 Network-dependent communication procedures for call establishment and termination are defined in Recommendations T.60 and T.5 for the Teletex and Group 4 facsimile services, respectively.5 This Recommendation defines the end-to-end procedures to be used within the Teletex and Group 4 facsimile services.6 Specifically, this Recommendation concerns the end-to-end control procedures that are network-inde-pendent. The network-dependent procedures forming a network-independent transport service are specified in Recommendations T.70 and, as applicable, T.71.7 The procedure described in this Recommendation should also be used between a Teletex terminal and a Teletex/telex conversion facility (see Recommendations F.200, T.60 and T.90).8 Interworking between Teletex and services other than telex, and between Group 4 facsimile and other services is for further study.9 This Recommendation assumes that the terminal initiating a call is the terminal regarded as responsible for call charges and that it retains full control of the call.10 The provisions in this Recommendation are to be regarded as a first stage in the establishment of Teletex and Group 4 facsimile services in accordance with Recommendations F.200, T.60, T.61 and T.70 as defined in 1980 and Recommendations F.161, T.5, T.6 and T.73 as defined in 1984, respectively. Enhancements and additions to these Recommendations must ensure compatibility with established services.
