    Hi Daniel,

    We might be able to help on the ASI Signal. We are developing an ASI Module
    for our AP3000. This is a 3 Port ATM Switch.

    One of the applications we have had is for helping with Doppler Shift by
    Cell Buffering across the ATM Backplane of the switch.

    We would do this by taking a HSSI output from the Satellite Modem, into a
    DTE HSSI Module. Then the data would be converted to ATM cells across the
    backplane and reconverted and ouput through another Gapped Clock HSSI
    Module. This would then connect to a HSSI Interace on a Router.

    Potentially once the ASI Module is out of development we could offer you a
    similar scenario.

    My Questions would be:

    1. Do you require a fixed delay
    2. What will be the likely traffic speed
    3. What is your timescale

    I hope we can help.

    Regards

    Mike

    Subject: satellite delay simulator

    Dear all,

    My company NEWTEC is looking for a true delay simulator
    ( at IF 70MHz or 140MHz or L-band ) that can generate signal
    delays of several hundred milliseconds comparable to 1 or 2
    satellite hops.

    Alternatively we are looking for a delay simulator capable
    of generating the same delays on a DVB-ASI type of signal.

    Does anyone know if such equipment is commercially available ?
