MultiModemUSB User Guide
Introduction
The MultiModemUSB, model MT4X56USB, is a Universal Serial Bus (USB) Concentrator that contains four full-featured V.90 modems and a USB port which allows additional MultiModemUSBs to be daisy-chained together. These features allow any system running Windows 95/98, Windows NT 4.0, or Windows 2000 and equipped with a USB port to quickly and easily add modems four at a time, using MultiModemUSBs, without opening the case. The modems can be used for virtually any existing datacomm application including Remote Access Service, dial-out, Internet proxy services, business Internet services, or multiple-modem client communications.
Using Microsoft or other third-party software, users on the same network as the USB host can share modems, gain Internet access, and double or even triple bandwidth by using more than one modem simultaneously with Multi-Link PPP bonding. The MT4X56USB includes a complete set of Internet business applications. The four dual-mode 56 Kbps modems support the new ITU V.90 standard and offer backward compatibility with K56flex. They support Class 1 and Class 2 fax, MNP 3 or 4 and V.42 error correction, along with MNP 5 and V.42bis data compression. Complete data and fax softwar e plus a large compilation of Internet applications are included on a CD ROM from TUCOWS. The CD includes client/server software for email, web hosting, FTP servers, news servers/clients, and web browsers.
The MT4X56USB modem concentrator is designed to operate efficiently in V.90 communication links, address the needs of newer datacomm applications and preserve the investment users have in legacy systems. Each modem is equipped with remote configuration to configure modems anywhere in the network, flash memory for firmware upgrades, DTMF tone detection, and three-number storage for automatic dialing.
