In California at least it's two analog lines required for fire alarms. <br class="">
You can use RJ31X series jacks to share them with other utility-type <br class="">
applications downstream like fax machines, postage meters, etc.<br class="">
<br class="">
We had a customer who wanted to use FXS ports off of our TA900 Adtran <br class="">
for this and while it would technically work just fine as far as <br class="">
compatibility we (and the fire alarm company) insisted that they keep <br class="">
the analog lines.<br class="">
<br class="">
A few months later one of the batteries powering their big UPS exploded, <br class="">
taking the Adtran out of service as well as generating copious amounts <br class="">
of toxic smoke. The fire alarm worked and the damage was very limited.<br class="">
