Motorola V.3400 Modem

As a Data Modem, it is compliant with ITU-T V.34, the V.3400 incorporates advanced technology that enhance operation on less-than-ideal transmission lines. These include: echo canceling, automatic adaptive line equalizing, trellis coding techniques, adaptive baud rate selection, transmit pre-emphasis, automatic transmit power selection, constellation shaping, non-linear encoding and pre-coding. 

The Motorola V.3400 is a high performance V.34 data and fax modem that allows users to transmit critical applications at 28.8 Kbps in synchronous and asynchronous environments. Motorola's technology leadership continues to offer exceptional speed, features and versatility for all networking needs. 

As a Fax Modem, the V.3400 is fully CCITT Group III compatible to let you communicate with any other Group III compatible fax device. The V.3400 conforms to the EIA-578 standard interface between and fax modem and a computer with fax software. When used with an EIA class 1 software package, the V.3400 can send and receive a fax document at 14400, 9600, 7200, 4800, or 2400 bps. T.30 error correction ensures your fax will arrive to its destination without transmission errors. 

Motorola V.3400 Modem Features 

• Operates as high speed fax, allowing communication with any CCITT Group III compatible fax device anywhere. 
• Front panel and AT driven remote configuration allows option settings of a remote unattended modem to be changed over the phone line. 
• CCITT V.8 compliant auto-mode ensures connection at the highest common rate. 
• With Automatic Rate Adaptation (ARA) the modem dynamically adjusts its data backward or forward. 
• Multiple levels or security from password to password with callback to user programmed. 
• Dial backup allows the modem to switch to a dial line connection if the leased line fails and return to leased line operation automatically 
• With integrated V.23 bis , separate modem and auto-call units are not needed. Also, you need only one port on the host machine, eliminating additional hardware expense. 
• CCITT standard v.42 bis, for asynchronous error correction/data compression. 
• AT command set compatible 
• 2-wire and 4-wire leased line operation 
• Storage for nine phone numbers 
• Autodial and auto-answer 
• Call progress indication 
• Software volume control 
• Rack-mountable
