Proprietary Information
Doc. No. 100394B
October 19, 1999
ADSL (Asymmetric Digital Subscriber Line) is a transmission
technology used to carry user data over a single twisted pair line
from the Central Office to the customer premises. The downstream
(Central Office to Customer Premises) direction typically supports
a much higher data rate than the upstream or return (Customer
Premises to Central Office) channel. This asymmetric nature lends
itself to applications like remote LAN access, Internet access, and
video delivery. The downstream data rates can go up to 8 Mbps.
The upstream data rates can go up to 1 Mbps. Actual data rates
depend on the transceiver implementation, loop length,
impairments, and transmitted power.
The Conexant ADSL Modem Device Set for PCI Applications is
based upon a scalable architecture. This architecture will enable
the device set to support an emerging set of ADSL specifications
called G.lite. G.lite is expected to make it possible for telcos to
deploy consumer-oriented, “always on” 1.5 Mbps Internet access
services without the need for splitter equipment or wiring changes
at the customer premises.
