摘要： A dial unit is detachably mounted on a public telephone for equal access and includes a keypad section, a registration table section, a determination processing section, and a transmitting section. The keypad section key-inputs a dial signal. In the registration table section, area codes corresponding to specific destinations to be handled as a long-distance call and a carrier code corresponding to a specific carrier line having a right of a carrier to the specific destinations are registered in advance. The determination processing section includes a dial signal determination section for determining whether or not the first digit of a dial signal to be handled for a long-distance call coincides with either a "1" or a "0", a dial signal storage section, an equal access determining section, and a carrier code adding section. The transmitting section converts the dial signal, which is temporarily stored in the dial signal storage section when a non-coincidence is determined by the equal access determining section, or the dial signal, to which the carrier code is added by the carrier code adding section when a coincidence is determined, into corresponding DTMF signals and sequentially transmits the DTMF signals after key input by the keypad section is completed.
