This BITS object is the standardized (RFC-aligned) counterpart used to selectively enable individual SNMP notifications a cable modem can send, such as DHCP failures or dynamic service request failures, and it also depends on the SNMP notification MIBs from RFC3413 actually being configured to deliver them. An operator turns on only the bits for conditions worth an alert, and because the spec says the value should revert to its default after a reboot, any custom notification selection needs to be reapplied or persisted by the device's own configuration save mechanism. As an example, if only bit 7 (cmDHCPFailNotif) is set, the modem will emit a notification specifically when it fails to obtain its DHCP lease, while all other listed conditions stay quiet.
