What is hwCnuIndex?

This value, bound to ring check trap notifications, reports the CNU (Coax Network Unit) ID involved in a detected ring-check condition. An admin reading a ring check trap uses this ID to identify which specific CNU on the network experienced the loop condition that triggered deactivation. A value of 5 in this field of a ring check trap identifies CNU 5 as the device involved in the detected ring condition.
