Maximum Tx Power
ATU-C/ATU-R
The maximum transmission power settings for the ADSL
Transmission Unit
– Central Office (ATU-C) and ADSL
Transmission Unit – Remote Site (ATU-R). The range may
be limited according to local guidelines when Spectrum
Management is set to Enable on the Spectrum
Management screen (menu selection
A-A-G
):
+12dB
to
–14dB
in 1 dB increments (Default = +12dB)
Line Profile
The name of the general line configuration profile (up to
32 alphanumeric characters). Press Ctrl-v to display a list of
all available line profiles configured on the card. Either
select an existing profile to change, or select New Profile to
create a new line configuration profile. An asterisk (*)
indicates the profile is referenced by other ports.
Each profile name must be unique. Up to 30 profiles can be
configured. Profiles can be used by multiple ports and can
be changed at any time. All ports share a single default line
configuration profile as part of the factory defaults.
Maximum Tx Rate, Minimum Tx Rate, and Target SNR
Margin are part of the general line configuration profile.
Maximum Tx Rate
ATU-C/ATU-R
The maximum transmission rate for the ATU-C and ATU-R.
The range may be limited according to local guidelines
when Spectrum Management is set to Enable on the
Spectrum Management screen (menu selection
A-A-G
):

Minimum Tx Rate
ATU-C/ATU-R
The minimum transmission rate acceptable for the ATU-C
and ATU-R. Any rate below this, sustained for at least
3 seconds, generates a Loss of Signal (LOS) status.
