We have a Comcast business triple play with digital voice at a small church. We have figured out that our alarm panel has been unable to contact its monitoring service and this has been going on since April (review of phone logs places original failure between April 17 and April 23).The alarm company says the "line is broken," but I have found that all lines have dial tones, and calls can be made in and out on all of them, including both that serve the alarm panel. Internal cabling has been untouched for years.
But today, something clicked in my mind, and I tried to place a call using a phone that can be made to pulse dial (i.e., emulate old rotary phone). I could not dial out. Tomorrow, I am going to ask the alarm company if the alarm mainboard is trying to pulse dial during its periodic check-ins.
So, here is the question. Could it possibly be that we had pulse dialing available but Comcast discontinued it during the time frame I stated? If so, they didn't tell us, and that would explain why we've had an alarm that couldn't call out for help.
I tried phoning Comcast for support, but the guy I got claimed that pulse dialing works at this address, which is not so.
Solved! Go to Solution.
Solved. The alarm company discovered that the mainboard of the alarm was indeed programmed for pulse dial only, and evidently Comcast discontinued pulse dial support recently.
Fault to Comcast for inept over-the-phone support, and also for failure to notify us in the first place.
Any idea when exactly Comcast discontinued pulse dialing? I work at a school and I think we may be in the same situation with our alarms. In any case, thanks for the info!
