TECHNICAL REQUIREMENTS TO BE MET WHEN PROVIDING REAL-TIME BOTHWAY COMMUNICATIONS BETWEEN TERMINALS OF THE INTERNATIONAL TELEX SERVICE AND DATA TERMINAL EQUIPMENTS ON A PSPDN OR VIA THE PSTN
The procedures defined in this Recommendation enable telex subscribers to communicate with both packet-mode and character-mode data terminal equipments (DTEs) connected to a packet-switched public data network (PSPDN). Conversely, users of packet-mode and character-mode DTEs as well as character-mode DTEs accessing a PSPDN via the Public-Switched Telephone Network (PSTN), may communicate with telex subscribers.
