The Aster 5 series uses the superior Telindus DSP technology to achieve data-transfer rates (uncompressed) of up to 33.6 Kbit/s on leased lines and PSTN dial-up circuits with automatic or user-controlled (e.g. by the network management system) fallback based on custom-defined line-quality thresholds.
 
The modem is designed for both 2-wire and 4-wire analogue lines.
