About the Hotwire ATM Line Cards
Hotwire ATM Line Cards
The Hotwire
®
8335, 8355, 8365, and 8385 Asynchronous Transfer Mode (ATM)
Line Cards are circuit boards mounted in a Hotwire 8620 or 8820 GranDSLAM
(Digital Subscriber Line Access Multiplexer) and used to transport ATM cells at
high speeds over a single twisted-pair connection.
Model 8335 supports Symmetric Digital Subscriber Line (SDSL). It can be set
to AutoBaud to the highest rate the loop can support, or to use a fixed line rate
from 144 to 2320 kbps.
Model 8355 supports ReachDSL. It automatically adjusts to the highest rate
the loop can support, from 32 to 2176 kbps.
Model 8365 supports Asymmetric Digital Subscriber Line (ADSL). It can be
set to adapt to the line conditions at startup, or set to the following fixed rates
depending on line code:
— G.dmt and ANSI T1.413: 32 to 8000 kbps downstream and 32 to 832 kbps
upstream.
— G.lite: 64 to 3008 kbps downstream and 32 to 512 kbps upstream.
Model 8385 supports Single-pair High-speed Digital Subscriber Line
(SHDSL). It can be set to adapt to the line conditions at startup, or set to a
fixed line rate from 200 to 2312 kbps.
Part of Paradyne’s Hotwire Connected™ program, the cards interoperate with
third-party DSL endpoints providing end users with the ability to select the best
equipment to fit their application. The new line cards also integrate support for
multiple DSL services on a single card.
