other end into the internal ADSL port on the splitter.
Step 2: Connect the telephone to the phone port on the splitter with another telephone
cable.

4.15.1 Introduction
Router 1-Port ADSL FIC/Router 2-Port ADSL FIC, the 1-/2-port ADSL over ISDN
interface card, uses the RJ-11 connector for the WAN interface. It allows a LAN
subscriber to connect to the DSLAM at the central office over a regular analog
subscriber line or telephone line. Thus, the subscriber can access the ATM/IP
backbone or the Internet to enjoy services such as high-speed data communication
and video on demand (VoD).
The card transmits data in the high frequency band above 138 kHz. Therefore, it can
provide services on the same line without interfering with the ISDN service being
