How can I tell if live lines are plugged into my PIKA analog card?

Question:
How can I tell if there are live lines plugged into my PIKA analog HMP fxo card?

Answer:
You can use aohtest to detect the voltage on the line. In this example, we are using 4 port card. Only trunk 2 is actually connected to a live analog line. While the trunk is onhook, the voltage greater than 48V. When it’s offhook, it’s approximately 8V.

Hi,

Is it possible to do similar test using DaytonaMM board? I mean to measure voltage value on line.

thanks beforehand,
Murad

Hi Murad,

I'm sorry, but this functionality is not available on the Daytona MM DSP boards.

The HMP boards use a different analog line interface with more control capabilities.

Hi Rod!

Thanks you for your response. Is it a hardware limitation of DaytonaMM?

And does HMP boards support high impedance logging?

many thanks beforehand,
Murad

Hi Murad

The Daytona MM (DSP board) does not have the Control lines / circuitry built on that card.

On the HMP Analog boards, it's a different line interface with LOTS of options for configuration and getting information from.

Passive Logging - High Impedance

Analog - FXO boards can be used for passive recording ( DSP and HMP boards )

Digital - The PrimeNet MM DSP board and the Digital HMP PCIe boards are capable of being used for Passive Recording.
