ASMi-52: 2/4-Wire SHDSL Modem

Maker : RAD Data Communications, Ltd.

The ASMi-52 modem uses SHDSL technology, complying with the ITU and ETSI standards, to extend the range of digital interfaces. The ASMi-52 device offers extended distances and variable data rates from 64 kbps to 4 Mbps. It uses TC PAM-16 line coding, equalization, adaptive filtering and echo cancellation to compensate for line impairments, bridge taps and mixed cabling. This provides high immunity to background noise and enables transmission of multiple SHDSL lines on the same physical cable. Standards compliance enables the ASMi-52 to work opposite third-party vendor TDM equipment that supports the SHDSL standard. It also works opposite the LRS-52 SHDSL modem rack and the DXC SHDSL modules. Monitoring, control and diagnostics of local and remote units are available via a supervisory port. The ASMi-52 is available as a standalone unit, which can be mounted in a standard 19" rack using special hardware.
