DSL Port Provisioning Help

To provision DSL port settings:
  1. Either select individual ports or use the Select All button for bulk selections. Use Clear All to clear all the ports.
  2. Verify the port provisioning settings.
  3. Click the Apply button to configure the selected ports.
To update the displayed settings, click the Refresh button.

SLOT
Displays the slot number and the card description.

DSL Port Profile


Click on the drop-down menu next to the desired field to select the proper value or enter the value in the field provided.

NOTE: You can check the DSL Port Profile to select all of the values and then check a port number to configure that port with the checked values.

Oper Status

Indicates the operational status of this port.

Admin Status

The administrative status of the interface.

Values:

Up: The interface is enabled and up, and the status of the interface should become standby or operational.

Down: The interface is disabled and down, and the status of the interface should become shutdown.

Testing: The interface is under test, no operational packets can be passed.

Description

 Port description field which provides a mapping between the physical port (or bonded interface) and the subscriber.

Line Type

The DSL type supported on this interface.

Values:

adsl: ADSL

shdsl: SHDSL. Not compatible with shdsllatest firmware.

sdsl: SDSL. Not compatible with sdsllatest firmware.

shdsllatest: Compatible with future versions of firmware code. Required for autobaud.

sdsllatest: Compatible with future versions of firmware code. Required for autobaud.

vdsl: VDSL

shdsl-2btl: This is the default line type for a G.SHDSL interface. With this setting, the device can perform automatic baud rate adaption. This allows receiving devices to communicate with transmitting devices operating at different baud rates without the need to establish data rates in advance. By determining the baud rate from the transmitting device, the receiving device automatically trains to match the line rate of the incoming data.

Default: shdsllatest

Refer to the release notes for your device firmware revision levels.

Line Status Change Trap

Specifies whether a line status trap should be sent whenever the DSL line goes up or down. Note that this setting does not apply to line status traps sent during system bootup. During bootup, line status traps are not sent.

Enabled: The linkUp, linkDown, and Line Status Change Traps are sent.

Disabled: The Line Status Change Traps are not sent.

Auto: For ADSL, a trap is generated on a line status change that is not due to a dying gasp

Trellis Mode

Enables or disables trellis mode.

Network Time Recovery

This field indicates whether Network Timing Recovery mode is enabled on the DSL modem.

If true, the Network Timing Recovery mode is enabled, if false, it is not.

Transmission Mode

ADSL transmission mode. Supported values:

Autonegotiate: The modem automatically negotiates all supported transmission modes. The modem uses the G.hs protocol to negotiate a transmission mode in this order: T1.413, then G.dmt, then G.lite.

Full rate: Full rate T1 ADSL modem. This is used for connecting to full rate T1.413 issue 2 modems.

G.lite: The modem negotiates rates up to 1536 Kbps upstream and 512 Kbps downstream (G.992.2)

t1mode : Full rate T1

G.dmt: G.dmt is a higher-bandwidth variant of G.lite that provides for downstream speeds of up to 8160 Kbps. G.dmt is defined in ITU specification G.992.1.

G.hs: The modem negotiates only G.dmt and G.lite modes. G.dmt has priority over G.lite

ADSL2: The modem negotiates rates up to 12 Mbps downstream and 3.5 Mbps upstream.G.992.3 ADSL2.

ADSL2plus: The modem negotiates rates up to 24 Mbps downstream and 1 Mbps upstream (Annex M allows upstream up to 3.5 Mbps) G.992.5 ADSL2+.

reachDslMode: the modem negotiates only reach DSL mode.

Default

Autonegotiate

Channel Mode

 

Specifies the channelization of the ADSL line. Supported values:

fastonly

interleavedonly

POTS Bypass Relay Duration(sec)

The maximum duration in seconds that an ADSL POTS low-pass filter bypass relay will remain active (closed). The relay will automatically return a line back to normal (open) mode when this timer has expired.

Values: 1 to 300

Default:

60

Only valid for ADSL-SPLTR-32 cards.

Discrete Multi-Tone Mode

Parameter that selects whether there is overlap (echoCancel) or no overlap (freqDivMux) of bins.

Default: freqDivMux

Annex M Mode

true

false

Annex-M PSD Mask

The maximum transmit PSD allowed in the downstream channel on an Annex-M line.

Values:

eu64

eu60

eu56

eu52

eu48

eu44

eu40

eu36

eu32

all

DPBO Profile Index

Index number for the downstream power back off (DPBO) profile. 0 disables the DPBO profile.

DPBO Fallback Profile

The index of the DPBO fallback profile. The fallback profile is only used for VDSL fallback when falling back to ADSL mode. 0 disables the DPBO profile.

Fallback Default VPI

The system supports ADSL2+ fallback to allow connection to either a VDSL2 or an ADSL2+ modem to a VDSL2 loop.

This setting specifies the VPI for the system to fallback to on an ADSL2+ connection if it cannot negotiate VDSL2. By default the system uses a default VPI/VCI of 0/35. You can change this default in the Fallback Default VPI and Fallback Default VCI fields.

Fallback Default VCI

This setting specifies the VCI for the system to fallback to on an ADSL2+ connection if it cannot negotiate VDSL2.   By default the system uses a default VPI/VCI of 0/35. You can change this default in the Fallback Default VPI and Fallback Default VCI fields.
