where
<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>.
This command shows the line operating values of an ADSL port.
An example is shown next.

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 MSAP2000 AAMS, during negotiation/provisioning
message interchanges.
2. At the time of writing, the MSAP2000 AAMS always uses Trellis coding.
