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

UNKNOWN - Used when the modem is disconnected, and in any situation where a valid diagnostic wasn't loaded from the modem.
A - Annex-A.
B - Annex-B.

C - Annex-C.
I - Annex-I.

J - Annex-J.
L - Annex-L.

M - Annex-M
ANSI-T1.413 - ANSI T1.413.
N/A - Mode diagnostic isn't available on this modem.

	Note
	When `LINE-MODE` is is not ADSL the value is NULL and CP will not show it.

VDSL-PROFILE

VDSL profile currently in use:

8a - Profile 8a.
8b - Profile 8b.

8c - Profile 8c.

	When `LINE-MODE` is is not VDSL the value is NULL and CP will not show it.

MODEM-STATE

Indicates if modem is connected to USB:

DISCONNECTED - The modem is not connected to CPX.
CONNECTED - The modem is connected to CPX.
FAILED - The modem is connected to CPX but there is a critical error.

MODEM-FAILURE

The reason of the FAILED state of the MODEM-STATE:

NONE - Used when the MODE-STATE isn't FAILED.

DATA-INTF-ERR - Troubles during the DATA interface initialisation.
DWNL-INTF-ERR - Troubles during the FW DOWNLOAD interface initialisation.
USB-NO-BW - Troubles because of insufficient BW (typically when ISO bandwidth is insufficient). The RTU_BANDWIDTH was detected on the USB device.
USB-SYSTEM-ERR - RTUSB troubles, the RTU_SYSTEM_ERROR was returned, typically reported when using more than 255 buffers on OHCI controller.
LINE-MODE-N/A - The modem connected does not support the selected LINE-MODE.

SN-MARGIN

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
