Both ISUP/SS7 implementations commonly discussed in this list use an E1/T1 card no differently from someone running ISDN over the card. What matters is a stable driver, zero bit rate errors due to card issues, and the availability of hardhdlc (hardware hdlc framer, depend on the driver having that). ISDN needs exactly the same feature set. You should find out if the Rhino card has hardhdlc feature, and if it's stable/reliable for ISDN. Google is your friend. On 09/08/11 15:14, Kevin P.
