I'm trying to set up a WAN connection between a BCM400 with a WAN card and a Contivity 1100. The Contivity logs are showing CRC errors but the BCM shows nothing. The set up is b8zs; esf; lcp echo at 10 and it is ppp not frame relay. I've used a T-Berd analyzer to check the lines and it shows all is well with the BCM and the Contivity. I don't have the right connector to do an inline test. Has anyone had any troubles with the BCM WAN cards and a Contivity?
