Abstract

The invention discloses a switching device for mobile phone TTY testing, including: a decoding unit, used to decode the signal input from the TTY device; a code conversion unit, connected to the decoding unit, used to receive the decoded signal from the decoding unit signal, and convert the decoded signal into a code that can be recognized by the PC; the level conversion unit, connected to the code conversion unit, is used to send the code that the PC can recognize to the PC; and the matching unit is used to perform impedance on the signal to match and enter it into the phone. The invention has simple structure and low cost.

Description

technical field [0001] The invention relates to mobile phone testing, in particular to automatic testing of mobile phone TTY (Teletypewriter, teletypewriter) performance. Background technique [0002] TTY equipment is mainly a device for people who are deaf, hard of hearing or language barriers to exchange information by typing or typing on the keyboard instead of listening and speaking. The TTY function of the mobile phone is a function required by the FCC (Federal Communications Commission, US Federal Communications Commission) mandatory certification and the third phase of the CDG (CDMA Development Group, CDMA Development Group) test. Through this function, the user of the TTY device can use the TTY device Access to mobile phones to achieve mutual communication between them and between them and ordinary mobile phone users. [0003] The automatic test of the TTY performance of the mobile phone in the current technology is mainly the test of the bit error rate. This kind ...
