This indicates that the receive HDLC is reporting CRC errors in the received frames. So the call was answered, but no LCP negotiation could take place due to the corrupted PPP packets.... >A show isdn 1 gives me a cause code 16, which doesn't make much sense >since this definitely is not normal. As far as ISDN is concerned it is, since the receive unit could not sync-up PPP, it basically gives up and hangs up on the caller - like if you or I received a call and just heard "noise", you try the "hello, hello" and then hang up. "Just hang up" is defined as cause-code 16. >To get going again, we have to power cycle it. This same thing happened >when it was running 5.0A. Do one of the incrementals fix this? Hmm, so the P75 *always* does that once it started until you power cycle it? You do nothing on the P400 - right ? Have you tried unplugging the BRI line on the P75 and then replacing it to see if that helps ? I see 2 possibilities ... either a bad P75, or a BRI line problem which is getting reset when the P75 is rebooted. Hence my suggestion to reset the BRI line without rebooting the P75 to see if that helped. If not, RMA the P75.
