I have a Partner ACS that experienced a power outage overnight. It was on battery backup, but this morning Lines 1-5 were no dial tone. We have a total of 6 lines and line 6 was the only one working. I couldn't get lines 1-5 working again on the ACS unit so I had them physically switched to 6-11 and they are working fine now. Here is what I tried. I had them turn it off and on twice. Waiting about a minute in between switching it off and on again. Using the PC version I uploaded the last good copy of the System Translations and restored from internal memory.

First: Is there something I didn't try that might have fixed it?

Second: What battery backup is good for this system. I am currently running an APC BE650.

Thanks in advance for any help on this.
