The meaning:

LINE-STATE

The state of the DSL line:

  • DOWN - The port is DOWN.

  • SYNCHRONISING - The port tries to synchronise with the remote side.

  • UP - The port is synchronised with the remote counterpart. The data transmission is possible.

LINE-MODE

Current line mode for the DSL line.:

  • ADSL - ADSL mode is used.

  • VDSL - VDSL mode is used.

ADSL-ANNEX

Indicates the current RX/TX SN margin detected by the device.

INTERLEAVE

Indicates the current RX/TX INTERLEAVE delay detected by the device.

VPI

VPI part of the VPI/VCI identifier. Only when LINE-MODE is ADSL.

VCI

VCI part of the VPI/VCI identifier. Only when LINE-MODE is ADSL.

State

The overall state of ATM VC:

  • DOWN - The VC is DOWN. Typically this occurs when DSL LINE-STATE is NOT UP.

  • UP - The VC can be UP only if the DSL line state is UP too.

Bw-In

Current downstream bandwidth available to AALs.

Bw-Out

Current upstream bandwidth available to AALs.

5sec-Thr-In

Last 5 seconds downstream throughput.

5sec-Thr-Out

Last 5 seconds upstream throughput.

5min-Thr-In

Last 5 minutes downstream throughput.

5min-Thr-Out

Last 5 minutes upstream throughput.

16.3.2. DSL-X resource statistics

This command can help to understand what is happening, in case of troubles:

d s dsl-x / d se dsl-x

Shows statistics information, such as the number of ADSL down/start, the number of modem disconnection/connection, the number of errors on the ADSL/VDSL line, etc.

The statistics of the DSL-x resource in ADSL mode:

[18:06:40] ABILIS_CPX:d s dsl-1
