Title: Pstn connecting apparatus capable of detecting cid signals through using a pstn channel
Inventor: CHOI KWANG JIN
IPC: H04M3/22
Filed: 2005-12-30
Abstract: A PSTN(Public Switched Telephone Network) connection device capable of sensing a CID(Caller ID) signal by using a PSTN speech path is provided to sense the CID signal by using one PSTN speech path for transceiving voice signals with a PSTN, and to deliver the sensed signal to an internal controller, thus there is no need to form a separate path and to use a high-priced dedicated chip. A CID receiver(600) senses a CID signal delivered together with a paging signal received from a PSTN. If the CID signal is received through the receiver while a subscriber terminal is in on-hook status, a voice signal and CID signal transceiver(700) sets a CID transmission path to deliver the CID signal to an internal controller. If the subscriber terminal becomes in off-hook status, the transceiver transceives a voice signal by setting voice speech paths among a polarity guard(200), a DC(Direct Current) holding and loop sensor(300), a transient time controller(400), and the internal controller.
