External Speakerphone Video Ready Modem
|
This External 56K high performance video ready modem has all the features you would expect in today's world of speed. Utilizing Texas Instruments chipset.
High Speed
The modem incorporates both V.90 & X2 transmission protocol. The main difference between these standards and previous ones, such as V.34 is the assumptions. Earlier standards made the simple mistake that both sides of the communication channel were analogue. V.90 & X2, don't make this mistake. They know that the other side of the connection is Digital: the Internet. Hence they are able to push the transmission speed to the maximum. So with V.90 you will get up to 56,0 kbps and with X2 you will get up to 28000 bps X2 = 56000 bps or 33600 X2 = 67200 bps.
V.90
The ITU (International telecommunications Union) introduced the standard V.90 in September 98 to solve the problem of the rivalry between X2 and K56flex. This will soon be the standard that all 56K transmissions will use, so make sure you can use it. All 56K modem support this as standard, and don't need have the firmware updated to accept it. We do not support K56 flex or winmodem, upgrade your firmware to X2 or V.90

For the Internet
These new modems were designed to be 100% Internet Compatible which means not only fast downloading through V.90, but also error free and quick (see Data Compression and Error Correction later). This modem has been tested in various Internet conditions and has been proven to work where other fear to go.
Full-Duplex Speakerphone
Many cheaper modems cut costs by missing this feature out. Todays modems includes this facility where a microphone, and speaker (internal speaker already built-in) can be connected directly in to the modem. So that even if you don't have a soundcard, you can still operate all the modem's voice features.
Video Ready V.80
Today's world of high speed communications has created a need for not only raw data to be sent, but also full-duplex (both directions at the same time) video data. The ITU introduced a standard H.324, and V.80 to accommodate this need.
Fax Modem:
If you need to just use fax technology, this modem with its controlling software will turn your computer in to a high performance fax machine. Just what you need when you are working from home.
Data Compression and Error Correction
Data compression allows the modem to send or receive more information in a shorter amount of time. Error correction helps correct for "line noise" from bad telephone lines. There are seven official protocols which are inter-connected within these modems. ITU V.42bis and MNP-5 are used for data compression.V.42, & MNP 4, 3, & 2, are used for error correction. This means that the modem can connect with any other modem and utilize any combination of these data compression and error correction protocols. MNP 4 & 5 work together as do V.42bis & V.42.MNP 5 can achieve a maximum 2:1 ratio of compression where V.42bis can achieve a maximum compression ration of 4:1.Your modem will automatically connect with the best settings the other modem can handle. The error correction protocols watch the data that is being sent and if it detects a difference in the piece of information being sent, it sends it again. So instead of the file or fax or web page or image being ruined, your modem just re-sends the parts it needs to and creates an exact copy at the other end.
