Table 26: Configuring Line Spectrum Profiles
Choose from the available Profile AIDs.
Assign the profile an identifiable Description (i.e. ADSL2 Plus...)
Do one of the following: either upload values from an existing file and modify them

Downstream PBO Profiles
DPBO is required to minimize the cross-talk to adjacent services in case that the CO unit is
not installed at the exchange (e.g. at outdoor cabinets). DPBO affects the transmission PSD
from CO unit in order to guarantee spectral compatibility. DPBO is supported only in
ADSL2plus and VDSL2 transmission modes. In this profile, the line configuration
parameters must be set to generate a modified downstream PSD mask for Downstream Power
Back-off.
To generate a DPBO Profile
1. In the Network Element tree, under Modem Profiles and under Spectral Profiles,
select Downstream PBO. The defined profiles are listed in the pane according to their
user assigned description and characteristics.
NOTE: Use the Add/View/Delete Profile buttons to define and manage the profiles.
2. In the displayed pane, click Add Profile. The Downstream PBO profile definition dialog
appears.
