	Tip
	Interesting chapter: Section 85.3.2, “Why the xDSL line is slow?”.

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

Annex currently in use in ADSL mode:

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.
8d - Profile 8d.

12a - Profile 12a.
12b - Profile 12b.

17a - Profile 17a.
30a - Profile 30a.
N/A - Mode diagnostic isn't available on this modem.

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

MODEM-STATE

Indicates if the 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.
NO_RESPONSE - 5 consecutive RTU_NO_RESPONSE errors were detected on the USB device.
OVERCURRENT - The RTU_OVERCURRENT error was detected on the USB device.
CANCELED - 5 consecutive RTU_CANCELED errors were detected on the USB device.
FW-ERROR - Troubles during the firmware download.
IRQ-INTF-ERR - Troubles during the IRQ interface initialisation.
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.

MODEM-NAME

Name of the DSL modem currently connected:

UNKNOWN - Unknown modem type, or not available.
Abilis-5800-UB - Abilis 5800-UB modem.
Abilis-ADSL2+ - Abilis ADSL2+.
Abilis-VDSL2 - Abilis VDSL2.

MODEM-MAC

The MAC address of the DSL USB device.

FW

Shows the current firmware version on the device.

SPEED

Indicates the current bit rate of the downstream/upstream direction.

ATTENUATION

Indicates the current RX/TX attenuation detected by the device.

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

The current downstream bandwidth available to AALs.

Bw-Out

The 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.

14.3.2. 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 line, etc.
