ITU-T V.8 BIS FRENCH-2000 公共交换电话网络和租用点对点电话型电路上的数据电路终接设备(DTEs)之间以及数据终端设备(DCEs)之间的共同操作模式选择和识别程序
Procedures for the identification and selection of common modes of operation between data circuit-terminating equipments (DCEs) and between data terminal equipments (DTEs) over the public switched telephone network and on leased point-to-point teleph
This Recommendation defines signals, messages and procedures for exchanging these over the PSTN and on leased point-to-point telephone-type circuits, when the modes of operation of DCEs and DTEs communicating over the connection need to be automatically established and selected, but before signals are exchanged which are specific to a particular Recommendation. Considerations are included for the standard analogue telephony mode of operation.
