The New In Door Unit (IDU) DW7000

On September 1

2005 Direcway announced, and started selling, the replacement for the

DW6000. The new unit is the Direcway DW7000 network termination interface (NTI).

For all intents and purposes the two products are virtually the same. They look the same

from the outside. They behave the same in the residential and commercial local area

network. The biggest difference is in internal clock speed of the DW7000 over the

DW6000. For single PC users not much performance enhancement will be gained. For

users with multiple hosts and any single user doing a large download while others are

browsing; then, upgrading to a DW7000 may be of interest. Also, with the new price

plans a residential user paying $59.99/month can upgrade to a DW7000 and a

professional service without a static IP address for $69.99/month. This pricing structure

may be the most valid reason for an upgrade.

September 1

also saw changes in Direcway’s service offerings and pricing structures

based on upload/download speeds. Direcway’s price and throughput plans now mirrors

WildBlue’s pricing structure.

In the remainder of this document if a statement refers to the DW6000 and DW7000 as

being the same then the unit will be referred to as a DWx0000.
