CHAPTER 1 : THE TAINET NETWORK SERIES MODEM
1.1 Description
• The TAINET Network Series Modem included T-288C, T-1496terbo, T-1496,
and ITM-3296bis, is a high performance, synchronous and asynchronous, full
duplex multi-standard modem. It is designed for use on 2-wire dial circuits and 2/4wire leased lines.
The TAINET Network Series Modem fully comply with ITU-T V.34
recommendation (up to 33.6kbps) as well as being compatible with ITU-T
Recommendations V.32bis/V.32, V.33, V.29, V.27bis, V.26, V.22bis, V.22, V.23
and V.21 international standards, operating at speeds of 14400, 12000, 9600, 7200,
4800, 2400, 1200, 600 and 300bits per second (depend on each model).
In V.34 and V.32bis/ V.32 modes, echo concellation provides 2-wire full duplex
operation over all PSTN circuits including those with satellite sections.
Compatibility is also provided with Bell 212A and Bell 103 operating standard.
• V.34 mode providing full duplex operation at up to 28.8 kbps (33.6/31.2kbps at
proprietary mode) with line probing, symbol rate and carrier frequency selection
(for T-288C only).
• A range of performance enhancing techniques are available for V.34 mode,
including Adaptive Precoding, Non-Linear Encoding (Warping), Constellation
Expansion, Multidimensional Trellis coding and Shell Mapping (for T-288C only).
• A 2 by 16 characters LCD display with back lighted control for configuration setup and monitoring conveniently.
• There are 10 factory default profiles and 10 user's profiles of your easiest
configuration setting.
• Line status monitoring including transmitted/received signal level, S/N ratio, signal
quality, frequency shift, delay, echo, retrain count, Tx/Rx baud rate, Tx/Rx
frequency, ..., etc.
