Description
Asymmetric Digital Subscriber Line (ADSL) is a data communications technology that enables faster data transmission over copper
lines.
ADSL Routers are key components in the FX80 system, as they handle the data communication on the trawl cable between the Bridge Control Unit and the subsea equipment on the gear. One router is physically located inside the Bridge Control Unit, while a similar router is incorporated in the Communication Hub in the Trawl Unit.
TipYou will see that the line rates will gradually decrease with time. If the line rates sink below 500 Kbps upstream and 1000 Kbps downstream, the communication has degraded so much that corrective
actions may be required. To rectify, you may need to reduce the resolution and/or the frame rate. You should also check the slip ring, the general quality of the third-wire cable, and specifically the pigtail and the splicing.

Connection Status
This field displays the current operational status of the ADSL Router.
|
• |
Up: The ADSL Router is connected to the Communication Hub, and the communication is operational. |
|
• |
ADSL Link Down: The communication between the Processor Unit and the ADSL Router inside the Bridge Control Unit is operational, but the communication with the ADSL Router in the Communication Hub is not serviceable. |
|
• |
Router not available: There is no network connection between the Processor Unit and the ADSL Router inside the Bridge Control Unit. The system is not operational. Make sure the Bridge Control Unit is switched on.

Line Rate - Upstream
This is the current communication speed from the Bridge Control Unit to the Communication Hub in the Trawl Unit. The same information is provided on the Status Bar in the bottom-left corner of the FX80 presentation.
Line Rate - Downstream
This is the current communication speed from the Communication Hub in the Trawl Unit to the Bridge Control Unit.
