Nokia DNT2Mi sp/mp user manual STU-C 6,3,3,1

Using Q1 menus

•STU-C (6,3,3,1)

This option defines the unit as a SHDSL Termination Unit (STU) Central office. It also sets the bit rate in the line as Fixed. STU-C determines line rate to the value given with the menu command Give line rate (6,3,3,1,2,1).

•STU-R (6,3,3,2)

This option defines the unit as a SHDSL Termination Unit (STU) Remote. It also sets the bit rate in the line as Rate adaptive. If the line conditions (attenuation/noise) allow, STU-R adapts to the line rate set on the STU-C side.

•Two-wire (6,3,3,1,2)

In the 2-wireoption, only Line 1 is enabled. Line 2 is idle. See Figure 8 for line connector pins.

•Four-wire (6,3,3,1,4)

In the 4-wireoption, both lines (Line 1 and Line 2) are enabled. See Figure 8 for line connector pins.

•PSD mask: Symmetric

Symmetric PSD mask defines the spectral shape of the signal transmitted to the line. The symmetric PSD is in use for both 2- and 4-wire modes (G.991.2 Annex B).
