Introduction to Hotwire
DSL Routers
What is a Hotwire DSL Router?
The Hotwire
®
DSL (Digital Subscriber Line) Router operates as a bridge and IP
router connecting a DSL link to an Ethernet network. This system provides
high-speed access to the Internet or a corporate network over a traditional
twisted-pair copper telephone line to the end user.
DSL Technologies Supported
Paradyne’s Hotwire DSL network supports the following types of technologies:
Hotwire IDSL (ISDN DSL) products provide IDSL multirate symmetric packet
transport and can operate over a connection with an ISDN repeater or digital
facilities. Data rates of 64 Kbps, 128 Kbps, or 144 Kbps can be configured.
Hotwire SDSL (Symmetric DSL) packet-based products provide high-speed
symmetric DSL services with bandwidth for business applications. These
products are configurable from 144 Kbps up to 2.3 Mbps. This gives service
providers the opportunity to sell multiple services with a single product.
Hotwire ReachDSL™ packet-based products provide high-speed Internet or
corporate LAN access over traditional twisted-pair copper telephone wiring,
regardless of line conditions (poor quality loops, long loops, or bad wiring at
customer premises), for guaranteed service delivery up to 18,000 feet. These
products are configurable from 128 Kbps up to 960 Kbps and give service
providers the opportunity to sell multiple services using a single product.
Hotwire RADSL (Rate Adaptive DSL) products are applicable for both
asymmetric and symmetric applications. The 1 Mbps symmetric operation is
ideal for traditional business applications while the 7 Mbps downstream with
1.1 Mbps upstream asymmetric operation provides added bandwidth for
corporate Internet access. RADSL products can also save line costs by
optionally supporting simultaneous data and voice over the same line.
