PROBLEM TO BE SOLVED: To enable working anywhere, by using mobile phones, since the conventionally-wired cable pair identification device cannot be used, without wire line (order line by means of telephone line). SOLUTION: The mobile phone (A) is used at a building side, while a mobile phone (B) is used at a workplace side. Cable pair collation is executed, while discussing via the mobile phones. Since a cable pair collating adaptor is used by adding it to the mobile phone, the current telephone line is not required within the operable area of the mobile phones, so that working efficiency is enhanced. The present invention is small in size and in weight, and earphones and each lead line, which tend to be disordered, can be contained in a case so that the mobile phone becomes very convenient for portability, and is accommodated in a pocket.
