The product speed is listed as the maximum download speed. The actual download speed may vary due to network traffic.
*
The reason the guaranteed speed for the 1Mbps product is left blank (--) is because there is no guaranteed speed for the 1Mbps product.
*
The maximum speed and even the entire service may not be available due to numerous factors, including the distance from the closest NTT base station, the condition of the NTT base station equipment and interference from other lines. In addition, some locations may be determined to be unsuitable for this service during installation.

No guarantee regarding bandwidth: The Type S option does not control data traffic, nor does it carry a guarantee of minimum bandwidth. Depending on the volume of data sent/received by other users at the same time, the data transmission speed may become inadequate for sending and receiving certain types of data, such as voice and streaming audio/video.
*
Transmission traffic restrictions: In order to prevent other users of the same hub from being inconvenienced by constant large volume transmission traffic by a single user, any user who averages a transmission traffic of 2Mbps or above for a continuous two-hour period may be asked to switch to the Type G option or may be suspended from further use of the Type S option.
