Phone line #1 is blinking,I have no dial tone. I have the Arris.
That indicates the Arris thinks there is a phone off the hook somewhere in your home, if you check all your phones, and there is none, take one phone and plug directly into the back of the Arris, see if that gives you a dial tone back,
If not, and Tel1 is still flashing, try a different phone (this may be the phone causing the issue), then reset the Arris, unplug the power and remove the battery, then put back, or there is a pin-hole reset eMTA to try.
If you still don't have dial tone after following kevinds's advice, I recommend checking out our document at How to fix no dial tone on all phones issue
I've also sent you a private message to see if you need any further assistance.
