correctly, the LED of the four ports will be red clearly; If the BRI line is connected correctly, and
it synchronizes to the other end successfully, then the LED will be green clearly.
Convert Cable: when users need to connect the ISDN phone to the ISDN card, the card should be
provided with extra power supply by C3 component and the power supply of server. At this
