SHDSL modem for high speed on twisted pairs

Edited by the Electronicstalk editorial team Jul 25, 2002

The Microtel Crocus SHDSL modem uses single-pair high-bitrate digital subscriber line technology to provide full-duplex transmission at up to 2.3Mbit/s.

The Microtel Crocus SHDSL modem uses single-pair high-bitrate digital subscriber line technology to provide full duplex transmission at up to 2.3Mbit/s over a single two-wire unconditioned, unshielded twisted-pair cable.

Operation is based on the new G.SHDSL standard for higher speeds and longer loop ranges, and the variable line transmission rate can be increased to 4.6Mbit/s using a two-pair version of the modem.

The use of TC-PAM (trellis-coded pulse-amplitude modulation) guarantees spectral compatibility with other transmissions in the same bundle, so that the risks of crosstalk and intermodulation effects are minimised.

The system is designed for ease of installation and fast rollout.

It is manageable under HP OpenView, and is supplied with advanced free maintenance software.

For central site applications, it is possible to mount up to 30 modems in a high-density card nest, with modular plug-in DTE interfaces providing maximum flexibility and aiding efficient stock management.
