Speed equals productivity. The new V.90 standard announced
March 1998, replaces two previously incompatible modem protocols--x2 and
K56flex. Using the best of the two previous standards, V.90 technology
allows modems to receive data at up to 56Kbps over regular phone
lines. This new speed is ideal for individuals and businesses
that want faster access without having to upgrade to more expensive
telephone connections such as ISDN.
| How Does it Work? |
Dial-up 56Kbps (V.90) access is possible using the new V.90 Standard. The V.90
technology is based on a new transmission technique which bypasses the analog-to-digital
conversion in the downstream path so that nearly all of the available 64Kbps network
bandwidth is used. Upstream data, which is typically
less speed sensitive, travels at the standard V.34 rate.

| Why Allstream? |
In order for Dial-up 56Kbps (V.90) to work, the V.90 communications technology
must be in place on both ends of the connection.
Allstream has standardized on USR network modems, which has enabled us to make
this speed available to our entire customer
base.

| Do You Always Connect at 56Kbps? |
Note that current Department
of Communications regulations restrict transmissions to a maximum of 53Kbps. In addition, there are a couple of other factors that
can affect the connection speed. Firstly, the speed of connection will vary with the quality of the individual customers' telephone
line (this has always been the case with 28.8Kbps or 33.6Kbps modems as well). The V.90 modems will automatically adjust transmission
speed as required. Secondly, there can only be one analog-to-digital conversion in the phone network along the path of the call.
This means that users connecting through a PBX (e.g. at a hotel) may not achieve 56Kbps (V.90) speeds, because there is typically an
extra analog-to-digital conversion for calls through a PBX.

| What do I need?
|
All you need is a modem which supports 56Kbps (V.90) transmission.
