64.4.3 ADSL Lineinfo Command Example
An example is shown next.
The service type in operation is the ADSL standard that the port is using: G.dmt or
ANSI T1.413 issue 2.
Trellis coding helps to reduce the noise in ADSL transmissions. Trellis may reduce
throughput but it makes the connection more stable.

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. “DS”
refers to the power output of the IES-1248-51V “US” refers to the power output of
the subscriber’s ADSL modem or router.
Information obtained prior to training to steady state transition will not be valid or
will be old information.
The atuc information fields show data acquired from the ATUC (ADSL
Termination Unit – Central), in this case IES-1248-51V, during negotiation/
provisioning message interchanges.
