Status/DSL Port Status Help

To display the current DSL port status, click the Refresh button.

Status

Port Number

DSL port number.

Oper Status

Indicates the operational status of this DSL port.

Admin Status

Indicates the administrative status of this DSL port.

Config Mode

CO: Downstream line

CPE: Upstream line

Transmission Mode

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.

ADSL2 Mode: The modem negotiates rates up to G.992.3 and G.992.4 ADSL2.

G.992.5 (ADSL2+): ADSL2+ Mode. The modem negotiates rates up to G.992.5 (ADSL2+).

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

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

gLite: G.lite, defined in the International Telecommunications Union (ITU) specification G.992.2, allows downstream speeds of up to 1536 Kbps. Advantages of G.lite modems include:

  1. No voice splitters required at the customer premises to separate voice and data traffic.

  2. Fast retrain capabilities enable the modems to respond quickly to changing line conditions.

  3. Efficient power management capabilities allows the modem to reduce power consumption during periods of low data transfer.

Reach DSL Mode: The reachdslmode negotiates only ReachDSL mode.

Down Line Rate CO (bps)

 

The DSL downstream (CO->CPE) line rate on this interface.

 

Up Line Rate CPE (bps)

The DSL upstream (CPE->CO) line rate on this interface.

Max Down(CO) Line Rate

This is the MAX line rate that can be supported on the line in the downstream direction.

Up Line Rate CPE (bps)

The DSL upstream (CPE->CO) line rate on this interface.

 

Max Up(CPE) Line Rate

This is the MAX line rate that can be supported on the line in the upstream direction.

Line Up Time d-h:m:s

 

Shows how long this link has been up in dd:hh:mm.

 

Line Down Count

Indicates how many times the link has been changed from up to down.

Line Status

The DSL modem status.

down - Transceiver is in IDLE MODE

downloading - downloading the BOOT code

activated - Transceiver is activated

training - Synchronization phase

up - Transceiver is in DATA MODE

test - Transceiver is in TEST mode

handshake - Transceiver is in HANDSHAKE phase

discovery - Transceiver is in DISCOVERY phase

analysis - Transceiver is in ANALYSIS phase

selt - SELT is in progress for this transceiver

delt - DELT is in progress for this transceiver

invalid- An unknown or invalid operation state was reported by the transceiver

Alarm Status

A trap is sent when the value alarm status changes for a DSL line. If the DSL port is down, this trap will not be generated.

Actual Transmission Mode

This field provides actual standard used for the connection based on outcome of negotiation with ATU-R. Possible values:

unknownMode, unknown mode or no connection made.

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.
