ABSTRACT:
A communication interface unit of a facsimile and a transformer for preventing a power source noise. The communication interface unit includes the transformer between a line unit and a MODEM for electrically separating the circuit boards of the line unit and the MODEM for preventing the power source noise causing data transmission error from flowing into the line unit. Also, a method for bonding the ferrite core and the housing in order to prevent damage to the transformer caused by an external force and minimizing generation of capacitance component by bonding. The bonding method can be more effectively implemented when an integrated circuit type data access arrangement circuit is used for accessing the PSTN. The present invention can prevent distortion of data generated by power source noise such as EFT and also prevent the ferrite core slipping off from the housing.
