52.2.3 Lineinfo Command
Syntax:
ras> statistics adsl lineinfo <portlist>
where
This command shows the line operating values of a DSL port.
An example is shown next.
The service type in operation is the ADSL standard that the port is using: G.dmt, G.dmt Annex
B, G.lite, ANSI T1.413 issue 2, ADSL2, or ADSL2+.
Trellis coding helps to reduce the noise in DSL transmissions. Trellis may reduce throughput
but it makes the connection more stable.
3
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 DSL 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-612-51A “US”
refers to the power output of the subscriber’s DSL modem or router.
Information obtained prior to training to steady state transition will not be valid or will be old
information.
<portlist> =
You can specify a single DSL port <1>, all DSL ports <*>
or a list of DSL ports <1,3,5>. You can also include a range
of ports <1,5,6~10>.
