I just searched the web.It was said that 179 issure is data call related.
Assume it was the ISDN interoperabilty issure between MAX6000 and Ericsson AXE 10.
1. set the signal to E1 without ISDN if possible
2. set the CLOCK SRC to no.
if it does not work, you would better off trying back-to-back connection with another MAX3000/6000 to test.
feel free to send me e-mail:
