1) Too far - over 4.5 to 5.5km away from DSLAM
Reason: This is the most likely reason. You need to be roughly within 4.5km away from a DSLAM/RSLAM to sync at 1Mbps. If you have coarser gauge wire, you may be able to be 5.5km away, give or take a few hundred metres.
Fix: None. Wait until DSL service is implemented in your area.
2) DSLAM is full
Reason: This is the second most likely reason. ADSL is very popular! There are only so many DSLAM line cards for so many customers per neighbourhood.
Fix: Keep checking every three months. People cancel, and equipment is upgraded all the time.
3) Brand-new phone number
Reason: It takes a few days for new phone numbers to appear into the DSL availability database.
Fix: The number will probably appear by itself in a couple weeks. If not or you're in a hurry, see #4.
4) Error in WTN database (aka "My next-door neighbour can get ADSL but I can't?!")
Reason: You can get ADSL, but the web tool says you can't. It happens. Errors are very rare, but with 4 million numbers constantly being connected, disconnected, or transferred, some numbers slip through the cracks.
5) CO not equipped
Reason: You are within 4.5/5.5km of your CO, but it doesn't have any DSLAMs. Most likely to happen in less urban areas.
Fix: None. Wait until DSL service is implemented in your area.
6) Loaded line (loading coil equipped)
Reason: A loading coil is a lowpass filter that boosts voice quality for certain phonelines. Unfortunately, it filters out the whole spectrum required for ADSL in the process. Most likely to happen in rural areas.
Fix: None. Wait until DSL service is implemented in your area.
7) AML (Added Main Line) equipped
Reason: An AML allows two phone signals to run on a single pair - you get two phonelines in one. Problem is, ADSL doesn't work on an AML'ed phoneline. So if you have multiple phonelines, you may have an AML'ed pair or two. Also, your neighbour may have an AML off your wire pair or vice versa if one of you have a faulty phoneline pair.
Fix: If it's because you have two phonelines, cancel one of the lines. If it's because you have three phonelines, try the phone number for the non-AMLed line. If not, there is little you can do, unless you know someone "in the inside". Your telco won't remove the AML, because that is a removal of service.
8) CLEC loop (local phone service from someone other than your local telco)
Reason: If you use local phone carrier from, say, Sprint, you can't get ADSL. Legal reasons regarding database sharing, I believe. Different long distance carrier is fine.
Fix: None, besides ditching your CLEC and buying phone service from your telco.
9) "Sympatico/Velocity website says Yes but Tube's DSL says No"
Reason 1: Wholesale ISP does not support that area at this time.
Reason 2: You are using an unlisted number. For legal reasons, your telco cannot divulge it to anyone, including another ISP.
Fix: Not much can be done for #2. For #1, try another ISP. If all else fails, use the DSL service from your local telco.
10) Party lines
Reason: They are not compatible with ADSL technology. Most likely to happen in rural areas.
Fix: Remove party line.
11) Digital lines of any kind (ISDN - Microlink/Megalink, Centrex, PBX, DNA)
Reason: ADSL is analog between you and the DSLAM. They don't work on lines running ISDN, a PBX, etc. This will happen in office buildings, hotels or convention centres.
Fix #1: Order a standard analog phoneline for ADSL, or try checking for ADSL availability on your office's fax line. That will be an analog line for sure. (Obviously if you have a business phoneline, you will have to go with business-class ADSL)
Fix #2: A company called http://www.travelnet.ca/ has a product called DataValet that will allow your hotel/motel to receive Bell Canada ADSL.
12) Public payphone, cellular phone number
Reason: Self-explanatory.
Fix: None.
13) Incompatible equipment on line
Reason: You have had service with an ISP on Nortel equipment in the past and that provider never submitted a removal request for the DBIC card.
Fix: Contact your old ISP and ask for the card to be removed so that your new ISP can request that your line be connected to a DSLAM
