where
This command shows the line operating values of an ADSL port.
An example is shown next.
Figure 162 Lineinfo Command Example
The service type in operation is the ADSL standard that the port is using.
Trellis coding helps to reduce the noise in ADSL transmissions. Trellis may reduce throughput
but it makes the connection more stable.
2
The numbers of milliseconds of interleave delay for downstream and upstream transmissions
are listed. The total output power of the transceiver varies with the length and line quality. The
farther away the subscriber’s ADSL modem or router is or the more interference there is on
the line, the higher the power will be.
Information obtained prior to training to steady state transition will not be valid or will be old
information. Annex A refers to POTS.
The
atuc information
fields show data acquired from the ATUC (ADSL Termination
Unit – Central), in this case AAM, during negotiation/provisioning message interchanges.
<portlist>
= You can specify a single ADSL port <1>, all ADSL ports <*> or
a list of ADSL ports <1,3,5>. You can also include a range of
ports <1,5,6~10>.

2. At the time of writing, the AAM always uses Trellis coding.
