PURPOSE:To reproduce various fault causes by supplying an optional bit pattern to an MODEM. CONSTITUTION:Even if malfunction occurs because a bit pattern[010,0001]= (61)16 is tranmitted to a center although a bit pattern[0110,0010]=(62)16 equivalent to an F is sent to an MODEM for, e.g., a failure in connection cord contact between a terminal equipment and the MODEM, a code which corresponds to the bit pattern[0110,0001]is undefined and the terminal equipment can not generate it, so that it can not be reproduced. For this purpose, a simulator capable of generating an optional hexadecimal number is connected to the MODEM to reproduce the undefined bit pattern optionally. |
