FIGURE 3-2 ADSL Port Log Examples
3.2.7 Loop Length and Data Rates (Rate vs. Reach) for ADSL Modes
In release 7.0, Annex M is available, which provides a higher downstream data rate for Annex A tpe interfaces.
The following figure compares the rate vs. reach for the various modes.

Log Message Meaning Action / Reference
Port Quality
Retrain
The Errored Seconds is too high, so the ADSL port is disabled and
enabled to retrain the link.
Audit will try to retrain the port
to an acceptable level
Port Stuck
Handshake
Retrain
The physical layer connection failed, so the ADSL port is disabled
and enabled to retrain the link
Audit will try to retrain the port
to an acceptable level
Port Min
Down Rate
Retrain
The connect rate is below the provisioned minimum downstream
rate, so the ADSL port will be disabled and enabled to retrain the

ADSL018 2003-07-30 15:26:42 4217 OTHER
Forced retrain of the port (Slot.Port:15.8) due to degradation of loop quality
("excessive" ES) above acceptable thresholds.
ADSL019 2003-07-30 15:26:42 4216 OTHER
Force retrain of the port (Slot.Port:15.8) due to the port's inability to connect
(attain SHOWTIME) after X handshake attempts.
ADSL020 2003-07-30 15:26:42 4215 OTHER
Forced retrain of the port (Slot.Port:15.8) due to its connection below the
configured minimum downstream rate.
