Abstract
A communication content recording apparatus supporting a digital communication such as ISDN is provided. A communication content recording apparatus includes receivers for receiving data transmitted/received between communication terminal units through ISDN, protocol processors for processing a frame on a signal channel received by the receiver according to a protocol, an information channel processor for converting the data on the information channel received by the receivers to data whose format is compatible with being recorded in a recording medium, and a protocol controller for controlling start and stop of the processing of the information channel processor according to messages which are obtained on the basis of a processing result in the protocol processors.
