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
