ITU-T S.10-1988 在标准的50Bd电报通路上降低字符传送速率的传输

The CCITT,considering(a) that there is a requirement for transmission at reduced character transfer rates on leased telegraph circuits;(b) that the cost of devices to subdivide a standardized 50-baud telegraph channel for simultaneous use by a number of users is relatively high;(c) that a number of Administrations meet the demand for transmission at reduced character transfer rates by providing a separate standardized 50-baud telegraph channel for each user and that the number of transmitted characters per minute is then limited by controlling the operation of the telegraph machine;(d) that,in the case of a pause in transmission for a period equal to or longer than 30 seconds,operators or subscribers are recommended to send a letter-shift (combination No.29 in International Telegraph Alphabet No.2) and to wait at least 2 seconds after the emission of this signal before recommencing transmission [Recommendation S.7,§(3)].

ITU-T M.880 SPANISH-1988 国际传真电报传输

Permanent circuits used between phototelegraph stations should be set up and lined up as 4-wire circuits between these stations. Circuits used normally (and preferentially) will be nominated international telephone circuits, the international line of which is normally extended to the phototelegraph station on a 4-wire basis, it being ensured that the terminal equipment (line relay sets, terminating sets, echo suppressors, etc.) is disconnected.

ITU-T M.850 FRENCH-1988 国际时分复用(TDM)电报系统

Figure 1/M.850 illustrates a basic international TDM telegraph system. The system operates via an international TDM telegraph link operated at 2400 bit/s and has a capacity of 46 telegraph channels at 50 bauds. Other modulation rates up to 300 bauds can be accommodated (with resulting reduction in channel capacity) as shown in Recommendation R.101, Table 1/R.101 [1].
