During the ML700 HSL Calibration (on page 4-21) process, the HSL is
calibrated according to user selected, predefined profile templates. A number of
factory configured templates are available, where the user can choose from these
templates during the HSL calibration. The user selects the templates according
to the site conditions and used technology. However, the advanced user may
want to further customize the default templates or create new templates. This
chapter provides detailed descriptions of these procedures for the advanced user.
DMT based systems, such as ML700, use customized Modem Profiles as
specified in BBF TR-165 and TR-252, to set all modem operation parameters as
specified in ITU-T G.997.1 standards. These include setting the range of data
rates according to required SLAs, optimizing modem operation by for the
specific infrastructure by adjusting and varying the SNR over specific
frequencies to counter the effect of specific types of interference signals.
ML700 supports ADSL2, ADSL2 Plus and VDSL2 technologies. The modem
profile customization criteria considers the DSL technology relevant for the site
and standards for the region in which the site is located.
