Introduction
The 1-port ADSL over PSTN interface module (SIC-1ADSL) provides an RJ-11 interface that can
work as a WAN interface. It allows a LAN subscriber to connect to the digital subscriber's loop
access multiplexer (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).
ADSL transmits data in the high frequency band above 26 kHz. Therefore, it can provide services
without interfering with the voice service being provided in the low frequency band (0 to 4 kHz) on the
same line. It provides downlink rates in the range 32 kbps to 8 Mbps and uplink rates in the range 32
kbps to 1 Mbps.
The SIC-1ADSL delivers these features:
•
Manual ADSL line activation and deactivation, providing a convenient fault location means.
•
Interface standards of G. DMT, G. Lite, and T1.413, autosensing.
•
Trellis coding (except for G. Lite) on ADSL interfaces, enhancing the stability of ADSL
connection.
