broadband access of at least 100 Mbps. This is at least 2,000 times faster than
a 56 Kbps dial-up modem, 14 times faster than the maximum speed of DSL, and ten
times faster than today's maximum speed of a cable modem.
•Low Cost - Deployment costs for DSDN are comparable to less
robust second-generation alternatives and significantly less expensive than
comparable FTTH solutions. DSDN technology delivers the performance of FTTH
without the high cost of installing fiber optic cable to the subscriber's
premises. While FTTH deployments can cost in excess of $3,000 per home, DSDN can
be deployed for under $1,000 per home passed.
•Proven - The SwitchPoint DSDN solution has been in commercial
operation more than two years and has provided broadband services to thousands
of customers. SwitchPoint deployed DSDN to more than 10,000 homes and 2,000+
customers in two test markets in Utah and is now marketing DSDN to network
builders and operators.
•Upgradeable - DSDN is engineered for upgrades to 1 Gbps with a
simple DSDN switch replacement; no new cable or construction is required. DSDN
can cost effectively scale to deliver multi-gigabit bandwidth performance that
matches FTTH, at a fraction of the cost.
•Scalable - DSDN networks will scale to support any number of
homes covering a market of any size and are compatible with Metropolitan Area
Networks (MAN) for their backbone traffic.
•Flexible - The SwitchPoint DSDN solution is extremely flexible
and can be deployed as a stand-alone 100 Mbps data network or as an overlay to
new or existing HFC cable networks or power grids.
•Deterministic - Each user in the DSDN network is connected to
an individual 100 Mbps port on the closest DSDN switch and do not share their
ports with other users on the network. The fully switched nature of DSDN
architecture maximizes available bandwidth and guarantees performance for users.
Flat, non-switched architectures such as cable modem networks share bandwidth
with all users on the network, causing effective throughput to diminish at peak
•Symmetrical - DSDN provides symmetrical, full-duplex
bandwidth, which means that users simultaneously can send and receive up to 100
Mbps of data. In contrast, upload speeds of cable modem and DSL are
significantly lower than their maximum download speeds preventing effective
deployment of premium services that require symmetrical bandwidth such as
videoconferencing, VPN and interactive gaming.
•Standards-Based - DSDN is fully compatible with standard
Ethernet and IP protocols; works with standard networking equipment and does not
require specialized customer premise equipment, such as a modem.
•Reliable - Neighboring DSDN nodes can be connected to each
other through redundant Cat6 links. Even if a cable is cut, DSDN's multi-path
routing capabilities easily work around the affected area to deliver continuous
•Secure - The DSDN network is an all-switched network. Security
is enhanced in an all-switched network because all users on the network do not
receive all packets. In flat network architectures such as cable modem, fixed
wireless and some FTTH broadband platforms, this level of security is not
