Lights on the ADSL modem and what they mean.
 
The description below may vary between modem makes and models but the principle remains the same across all makes and models. Please refer to your specific modem’s documentation  for light descriptions and functions specific to your modem:
  • Power light - Indicates the modem is on or off. Some modems have a 2 stage light:
    • Red while the modem is booting up or faulty,
    • Green and stable when the modem in ON and functioning.
  • DSL / ADSL - This light should be on. If this light is flashing or off, the modem is either still booting up or is unable to synchronize with the telkom exchange.
  • Internet light - This light indicated the connection to the internet. This will not be on when the DSL light is off or flashing.
    • This light should be on, Green, when there is no traffic going through the modem and flash when there is data going through.
    • Not on or not flashing, modem unable to connect to the authentication server or modem not configured
    • Light is burning red - usually means the username and password entered incorrect.
  • 1, 2, 3… - These lights indicate that there is a computer connected to the corresponding physical port on the back of the modem.
    • ON - Cable is connected and the device on the other side of the cable is also connected and on.
    • OFF - No cable plugged into this port or the device on the other end of the cable is off or faulty.

Jenny ADSL Capped and Uncapped

Jenny ADSL uses a Telkom line to connect you to the Internet. ;">For ADSL to work, you require a post paid Telkom line, ADSL service active on this line, ADSL data account, an ADSL modem and a computer.







The Telkom lines are a little difficult to understand. The one line is used for both talking on and the Data for the internet. Essentially, the 1 line is split into two sections.

  • The entire analogue line is installed and supplied by Telkom. This is the line that you would plug your telephone into and call someone on.

  • This analogue line is billed to the user’s Telkom account every month.

  • When you request for an ADSL line, they don’t come and install another line, they add the ADSL service to your already existing line. This ADSL service is often referred to as the ADSL line.

  • The ADSL service is either paid to Telkom if this service is with Telkom or, if this has been migrated to your internet service provider (ISP), you will pay this to your ISP. This price will vary according to the line speed you have chosen / require.

In addition to the line and ADSL service, you will also require the following:

  • ADSL data account is the amount of data you have in your package per month, eg 1Gb / 5Gb. This data generally doesn’t carry over to the next month if not used up. If you have opted for an uncapped account, you would never reach your data limit, however, if abnormally large amounts of data is downloaded or uploaded, you connection could get throttled / slowed down.

  • Computer / Device is the device that is going to connect the ADSL modem and use the internet through this ADSL modem. These computers / Devices can be connected to the ADSL modem via network cable or via wireless signal.Jenny ADSL uses a Telkom line to connect you to the Internet.
