ADSL Configuration
Configuration for an ADSLx user port is provisioned by the parameter set, which is a group of
attributes that determine the user port behaviors; and we call it as profile. The UniPhyer
LB-UA2348 provides a profile-based provisioning per the definition of ITUT G997.1 and RFC
2662 for ADSL line configuration data and a mechanism to associate the ADSL port to these
profiles. One or more ADSL lines may be configured to share parameters of a single profile.
The ADSL profiles of UniPhyer LB-UA2348 include:
Service Profile
The parameters include Rate adaptive mode selection, Min/max/planned bit rate, Interleaving
Max delay, and Minimum impulse noise protection.
Spectrum Profile
The parameters include the Power management setting, Min/max/target noise margin, allowed
ADSL modes of operation, Carrier mask, RFI band data, Maximum nominal aggregate transmit
power, Maximum PSD level, PSD shape (for ADSL2+), Power back off initiation, and
Maximum aggregate receive power.
TCA Profile
The parameters include ESs, SESs, UASs for interval and day PM, and LOS, LOF, LOPWR,
LOL, Error Frame for interval PM only.
The system provides up to 120 Service profiles and Spectrum profiles respectively, and provides up
to 64 TCA profiles. One of the profiles is a fix default that cannot be modified; users are allowed to
create, delete, and edit the other profiles. Each profile contains a parameter set for downstream and
upstream direction respectively. Users can also observe the actual values of these parameters
through CLI, Web-GUI, or EMS.
The ADSL configuration also includes the function for user to query the line status, the physical
layer status, and the channel interface status for ATU-C and ATU-R. The status information includes
the attenuation rate, actual net data rate, the line attenuation, SNR margin, transmission power,
actual interleaving delay, channel characteristics per subcarrier, quiet line noise PSD, …etc.
