This read-write INTEGER is a network parameter whose exact function the source MIB documents only as 'TBD', with no further detail provided. Based on its name and its placement among other comm-break-related parameters like parNetParmCbDelay and parNetParmCbMaxTimeout, it likely fine-tunes some aspect of the comm-break test timing, but an administrator should not assume specifics beyond what the vendor documentation states. For example, an operator encountering this object in a MIB browser should leave it at its configured default rather than guessing at an appropriate value, given the lack of documented semantics.
