enhance operation and provide cost and traffic reporting developed to suit the individual needs of the savings. The communication interfaces are based on T.4 and T.30 user. (Figure 60.8.) One main area of concern for facsimile users is the onward recommendations and follow standard facsimile protocols. Where these units are provided by suppliers different from the machine distribution of documents received at central machines maybe lo- suppliers, the NSF proprietary operation is often precluded. This cated in the mail room. Onward distribution is often delayed waiting can result in a loss of facilities and an increase in transmission time. for the next mail round, and onward transmission by facsimile to the It may also mean that because of simple interfaces used, MR, ECM, department in question is sometimes not felt desirable. 14.4kbit/s CCITT options are not implemented and transmission One solution being considered is that the facsimile switch can efficiency is limited. have a soft copy display of the facsimile message on a VDU. An operator would then display and readdress the document for onward 60.6.1 Managed network use transmission from memory. Clearly, for efficient operations, a suit- able compromise must be made between the switch capital cost and the time required by the operator, to re-route the document. By the provision of store and forward units with multiline PSTN access, a network operator or value added supplier can relieve the user of major distribution tasks and free the user's machine for other 60.6.3 Facsimile gateways work. With multiline access it is realistic to consider a regular broadcast transmission to 10000 recipients from a single originator The transmission of facsimile documents and of electronic mail or transmission to the store. To some extent the network operator can computer generated text are usually kept separate. However the schedule the traffic to suit network loading and therefore offer wide population of G3 machines has encouraged users on electronic practical tariffs whi
