E3 config guidelines


I have an E3 link b/w 2 sites. The E3 link is set up at both ends using a PA-E3 with a Cisco 7206VXR router. The PA-E3 module has an integrated DSU. According to the ISP, the E3 line is not terminated remotely with a DSU. In that case, should i use G751 framing for the line? Btw, the E3 link is unchannelized.


Re: E3 config guidelines

Often times complex troubleshooting issues are best addressed in an interactive session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

To utilize the resources at our Technical Assistance Center, please visit and to open a case with one of our TAC engineers, visit

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.
