Nam đọc trong tài liệu BCRAN trang 293 of 552 section Common DSL Systom and Problems:
Symptom:
DSL trains okay, and then retrains once the
telephone handset is picked up
Problem:
Excessive noise on the line when the phone is in use.
This is typically a telco splitter issue and should be
resolved by the carrier.
Symptom:
DSL functions properly, but there is static in
the phone handset
Problem:
Most likely the filter was either omitted or placed
between the wall jack and the DSL modem rather than
between the wall jack and phone. DSL and voice can
work together, but the filters must be in place for any
phone/fax on the shared line.
Symptom:
DSL not training to advertised speeds for
upstream/downstream transmission
Problem:
Typically, this is one of two issues. The most common is
that the circuit on the telco end has been misprovisioned.
Contact the telco to remedy the issue. The second
possibility is that the customer premises is outside the
distance limitations of DSL. Service will be inconsistent
at best in this case.
