    100 Mbps Speed - DSDN provides symmetrical, full-duplex
    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
    loads.
    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
    service.
    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
    possible.
