  The DCE ASM-9256D - ASM-9234D and ASM9232D high-speed dial-line modems are designed and manufactured for rugged industrial applications over the Public Switched Telephone Network (PSTN). The ASM-9256D and ASM-9234D utilize industry’s latest V.92 and V.34 modem delivers outstanding features, performance, and reliability in one cost-effective solution

These modems incorporate the latest data-compression and error-correction standards for improved data reception over marginal
and poor-quality telephone lines. Multiple levels of security with password
verification and security call back keep your valuable data secure from intruders.

The ASM-9256D/9234D/9223D modems are powered by a wide range of AC and DC power supply voltages. Its low power consumption and low stand-by current technology design makes the ASM9234D/9223D ideal for battery-powered system as well as regular AC powered operations.
