What could possibly go wrong?

The accompanying tweet that yours truly stumbled upon yesterday reminded him of something he was pursuing with regard to emergency situations that might arise at UCLA, e.g., the Big One.

Yours truly won't reveal the source of this info, which came after his request for information about the conversion of UCLA phone system from landline telephone service to VoIP (Voice over Internet Protocol). Specifically, yours truly was concerned about the capability of the new VoIP system in the event of an emergency such as a major earthquake that could cut off electrical power. If you followed news accounts of recent wildfires up north, you know that cellphones failed up there. Anyway, below is a quote from an email response to an inquiry by yours truly about the conversion that appears to be occurring in stages:

...There are a number of safeguards built into the overall VoIP design. Specifically:

• To account for internet outages, our VoIP connectivity runs on fault tolerant network switches (hardware) that provide redundant components.
• From a software configuration perspective, our VoIP connectivity runs on a dedicated, protected network subnet separate from regular internet traffic.
• To account for power failures, we have added additional battery backup units to allow for a 4-hour runtime in the event of a power outage, per the campus standard.
• Each phone configuration has a location assigned to it that is used for e911 purposes to allow first responders to know the location of the phone unit.*

Additionally, central campus is moving all departments to VoIP as the current telephone system is approaching its end of useful life...

Are you reassured? Yours truly isn't.

Note on a related subject:

The various periodic announcements related to emergency operations that you receive at UCLA refer to a low-power radio station operated by the university at 1630 on the AM dial that can be heard on campus and vicinity. Even if you think you don't own a battery operated AM radio, you probably have one built into your car. In recent months, the UCLA station - which normally transmits simple repeating messages at non-emergency times - seems not to be working. Yours truly has been in touch with those in charge who say the service will be restored. Sooner would be better than later. Just saying...

*The notation "e911" refers to 911 service for mobile phones. It is supposed to give the operator the location of the phone.
