Watson 5 Ethernet
Operating Manual
W5-Ethernet-Manual.doc
Version 2.0-01
3-8 Revision: 2006-04-27
Attenuation
The link attenuation is calculated by the modem assuming 0.4mm PE cable without bridged taps
and measured at 150 kHz (for linerates of 200 kbit/s up to 1'992 kbit/s) or 200 kHz (for linerates of
2'056 kbit/s and above). This calculated attenuation may differ from the attenuation measured by
other equipment for other cable configurations (other cable diameter, splices, bridged taps).
Both Signal Quality and Attenuation are effective maintenance tools for determining inadequate or
bad cable pairs. They are available with the DIAGNOSTIC Monitor command.
3.1.6 Wetting Current
The Watson 5 Ethernet plugin can source or sink wetting current over the DSL line. Wetting current
is configured per wire pair by jumpers located on the lower left corner of the plugin:
