Abstract: A method is provided for initializing an apparatus for transferring asymmetrical data, in which initializing time is reduced using a previously stored result. The method includes the steps of (a) determining whether data bit assignment tables assigning data based on the channel characteristics of the transfer line are effective and (b) transferring data based on stored characteristics of the transfer line without reanalyzing, when the data bit assignment tables are determined to be effective in step (a).

Abstract: A credit inquiry service system for inquiring about the credit standing of a check or credit card uses subscriber lines of a public communication network. The system includes credit inquiry terminals connected to the subscriber lines for generating and transmitting an inquiry request message requesting information regarding the credit standing of the check or credit card. The credit inquiry terminals also receive an inquiry result message corresponding to the inquiry request message via the subscriber lines. The system further includes a line multiplex device for one by one serially selecting the subscriber lines connected to the credit inquiry terminals, receiving the inquiry request message from one of the credit inquiry terminals connected to a selected subscriber line, and transmitting the inquiry result message corresponding to the inquiry request message to the corresponding credit inquiry terminal.
