    Default 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 itís offhook, itís 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

    Default Analog Interfaces and High Impedance Logging

    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.
