Need More Power


#1

I’ve got no voltage going to my POTS DID lines. The telco says my pbx should supply the voltage, after a half hour explaining that it’s a linux box running *. All I am left with is that there needs to be “48V ring tip ring ground”?

6 POTS lines, 8 DID lines --> AllenTel AT125-SM–>Rhino 24 FXO Channel Bank–>[[TE110P]AsteriskBox]
CA, USA

What is the best way to power these DID lines?

Thank you for your time,
day
