Default CO lines

I have identified that I have CO lines on my system, but I'm a little confused at the functionality of these lines. If there is a power outage beyond the UPS protection, will these CO lines still work? If so, do I have to plug in an analog phone to use them in the event of a power outage?

Default CO Lines

Use of The Emergency Transfer feature is the answer to this.
This feature provides basic telephone services in the event of
a power outage or a failed connection to Avaya Communication Manager. The ETR provides emergency trunk bypass or power-fail transfer for up to five incoming trunk loops to
five analog phones and maintains connections on return from emergency transfer mode
