A dedicated line stays connected 24 hours a day, but they are expensive and in many cases data is passed only a fraction of that time. Virtually Dedicated connections take advantage of this idle time by releasing the line when data is not being transmitted so that the port can be shared, substantially reducing the cost. The connection will be reestablished, quickly and automatically when there is more data to transfer.
Simply stated, Virtually Dedicated connections deliver the same functionality as dedicated circuits, but at a reduced cost.

When there is Internet traffic destined to your site,
NetIn.com establishes a connection (originates or dials)
to you. When there is no more data to pass, the
connection will be dropped automatically.

NetIn.com offers several different tier based pricing options for two way dial on demand circuits, starting at $20 per month. |
| GTE or SWB (depending on your location) provide an ISDN phone line (normal ISDN BRI service). | |
An ISDN BRI cost about $125.00 to install, and then cost around $60.00 per month for non-metered usage. Your phone company will have to provide exact pricing. |
| When there is traffic from your site destined to the Internet, the ISDN terminal adapter automatically establishes a connection to NetIn.com, and drops the connection when there is no more data to pass. |
|
Ascend Pipeline series ISDN terminal adapters are currently costing around $600.00. |
Two Way Dial-On-Demand (abbreviated 2WDOD) is what NetIn.com calls our offering of Virtual Dedicated Circuits.
2WDOD circuits are a new and upcoming means of accessing the Internet, and are currently based on ISDN technologies. The basic premise is using an Internet port only when needed, allowing a single port to be shared by several users. This gives the same functionality as a dedicated circuit, but at substantially reduced costs.
The process of terminating and reestablishing a connection is what is called Dial-On-Demand, and is implemented in a protocol called MP+. It is necessary for both sides of the circuit (the customer's side and the ISP's side) to be able to establish the connection. In other words, both sides need to be able to dial the other. This is called Two Way Dial.
2WDOD is well suited for small businesses or home offices, and individual "power users". If you are just starting your business's Internet connection and your data transfer patterns are such that there is over 50% idle time, then 2WDOD may be your dream come true.
While it is very difficult to guess what an individual considers to be acceptable performance, we have included some rules of thumb for estimating the amount of bandwidth that is needed for a number of users.
| Monthly Cost | Number of Light Users |
Number of Medium Users |
Number of Heavy Users |
|
|---|---|---|---|---|
| 64k 2WDOD + 64k bandwidth on demand ISDN | $20 | 40 | 20 | 5 |
The following is a table to help explain the costs associated with building a WAN connection. The phone company charges are estimations based on information from our customers. Your costs could vary, so ask your phone company for a quote. Also, the equipment costs are our best estimations based on pricing information as of November 1, 1997.
