Re: Rogers Home Phone Suddenly Stops Working - Telephone 1 Flashing

1. Have you removed all of your devices (phones, fax, etc) from the various telephone jacks in your home?  If not, try that.


2. Is it possible there is something (like an alarm system) that is "hard wired" into the telephone block at/near the demarcation point?  For example, an alarm system will "grab" a line and you will not get a dialtone on a phone as long as the alarm system is communicating with the alarm company.  Once that communication is finished you get your dialtone back, but if something like that didn't "disconnect" properly then it could be the source of your issue.  Do you have anything hard wired like that?

Now what happens is, anytime I connect a phone line directly or via a splitter from the phone modem "Telephone 1" jack to the wall jack, the "Telephone 1" lights on the modem flash, and there is no dial tone on any line. This was working for 16 years no problem, all of a sudden this stopped working.

It's really hard to say for sure what the problem could be without confirming the electrical state of all phone jacks, with just the Rogers modem connected directly to your in-home telephone wiring.  A direct connection.  No splitters, and no telephones or any other hardware connected to the telephone jacks.


I also double-checked Rogers' support article for troubleshooting common home phone issues.  Can you confirm that this is the status that you are seeing?  Tel1: solid green/flashing if the primary line is in use




When all telephones are on-hook or when no telephones are connected, the voltage measured between tip and ring should be around -48 volts DC.  When a telephone goes off-hook and closes the circuit, the measured voltage should drop to around -10 volts DC.  (I say "around" because some variance is normal, although with the modem (which provides battery and dial tone) directly connected to the in-home wiring, you typically see voltages that are close to spec.)


With no telephones connected, I would expect to see 48v.  If I see 10, something somewhere is creating a short.  It could be a bad cable, bad connector, bad something somewhere.  If I see anything other than expected voltages, higher or lower, it indicates a problem/fault and an invalid line state.


If the incoming Bell line is not disconnected INSIDE the home, then even if it is not connected to anything outside, it could develop a fault... and if water seeps in, that will also introduce a short in your line.



If your Rogers Home Phone works with a directly-connected telephone, the modem itself is fine.  If it stops working when connected to your in-home wiring, you will need to isolate and eliminate the fault... and it could be anywhere... and that will likely require the skills of a trained telephone technician.
