1. What is TELECOM？
•Telecom=(tele)-(communication)
•In short, Telecom delivers messages through an “electric” medium. So an "electric" medium is the subject of the Telecom test.
2. What telecom equipment needs to be approved the TELECOM certification?
The telecom equipment that connects to the PSTN/ISDN network must be approved the TELECOM certification.
•Telecom interface classification: FXS, FXO, XDSL, ISDN/T1/E1, Acoustic and HAC (e.g. Analog phone, IP phone) 。
■PSTN: Public Switched Telephone Network, it is also a telephone network commonly used in our daily lives.
■ISDN: Integrated Services Digital Network.
