<p>Data flow control applied to a packet communication system including data terminal equipments (DTEs), a first MODEM connected to one of DTEs, a telephone switching network (TSN) connected to the first MODEM, a packet switching network (PSN) having an assembly and disassembly equipment (PAD) and a second MODEM connected to PAD and provided between PAD and TSN and carried out by using MODEM control signals, logic signal "1" and "0", and control characters, DC1 and DC3, is performed by: discriminating a designated response signal, /REL in CONNECT alpha beta gamma delta /REL, from a header of data transferred through the first and second MODEMs each having a buffer memory used for error correction of the data; making the MODEM control signals effective and the control characters ineffective to be controlled when the designated response signal is detected; and making the MODEM control signals ineffective and the control characters effective when no designated response signal is detected, at PAD.</p> |
