DSL Troubleshooting Information & Guide
This is a simplified way of describing the way data flows to the Internet:
- Data is generated by your computer (ex: a request for a web page, video, or your e-mail)
- Flows over your ethernet cable to the DSL modem.
- Passes through the DSL modem and continues over a phone cable to the wall jack
- Travels to your outside phone box (NID) via the cabling inside your building.
- On to the Central Office (CO) building in your neighborhood
- Then to your ISP's (Tri-Lakes Internet) network
- Finally it goes out to the Internet (and back again)
Installing DSL service on a phone line
After the DSL is install, you will connect your DSL modem to a wall jack that services the telephone number that the DSL is installed on using a standard telephone cable. If the DSL modem needs to share the wall jack with a telephone, fax machine, or credit card machine, then you will plug in a DSL filter/splitter into the wall jack. The DSL splitter has two jack ports. One of the ports is unfiltered and is labled "DSL". Plug the DSL modem's phone cable into this port. The other port is filtered and is labled "phone" or "line". Plug the telephone cable into this port. This allows the telephone line and DSL to share the same line without interference. If you have other devices in your location that use the DSL line, each device will need to have DSL filter installed on it. Some newer modems have a built-in DSL filter/splitter. If you need more filters than the ones provided for you during installation, contact us and we'll find you some extras. To see a photo of a DSL filter/splitter, click here.
Once the DSL modem is plugged in to the wall jack (using telephone cable) and the power cord is plugged in to a power outlet (make sure to use a surge protector or battery backup if possible) it will go through a boot up routine and then attempt to contact the DSL equipment at the Central Office (CO). This is the "synching" of the DSL signal. It might take a few minutes so please be patient. The LED lights on the modem will indicate when the sync has completed. The sync LED may be labled "Sync", "DSL", or "Link" depending on the modem model. The Sync LED will flash as it's attempting to sync and will be lit solid once it has successfully synced. After the DSL is synced, the modem verifies your PPPoE account and allows your modem access to the network. Some modems have the "PPPoE", "Ready", or "Internet" LED light to show the status. If this LED light is flashing then it is attempting to login, if it is red then your account has been denied access, and if it's solid then you're online. It is recommended to always leave your modem powered on so that it's synced and ready for Internet traffic.
Connecting your DSL modem to your network/device
After the sync completes, your DSL service is running and ready to be utilized. You can connect it directly to your computer or you can connect it to a switch/router for the purpose of sharing your Internet connection with multiple devices via wired or wireless connection. Some DSL Modems have built-in routers which allow you to connect multiple devices directly to your DSL modem, thus eliminating the need for an extra device.
