The differences between the T1 and E1 versions are the frequency of the
two VCXO crystals, and part number of the two framer chips. Change those
to the E1 type and the card functions OK as a clock slave. A hardware
limitation means it will not perform properly as a clock master. As a T1
card clock master mode is OK. As an E1 card it isn't. Most people need
to slave most of the time to the great atomic clock in the PSTN, so this
isn't such a big limitation.
 
I never tried the card with Asterisk, but it should work for
CTR4/EuroISDN. I don't think there is support for any other protocols.
It works OK for the things I do with it, using libPRI and not using
Asterisk.
