Operators will have to determine which method is most appropriate for their business model. A bigger challenge arises when software version control support must exist in a hybrid CC and legacy environment. To be successful, operators must be able to differentiate between legacy and CC modems. Unlike many legacy systems, the CC specification was designed from the ground up to pay close attention to the security of user data and of operator revenue streams. BPI uses accepted cryptographic algorithms that have withstood the test of time.
Fault management includes the remote detection, diagnosis and correction of network problems.
CC modems support SNMP management traffic across both the customer's and cable-system's interfaces. Installers can use SNMP to perform onsite diagnostics and fault isolation on both the cable modem and cable TV plant. Reporting of events may be fully configurable by priority class and may be disabled completely. Modems implement a local event log that is available via SNMP and that persists across reboots. Events also may be sent to a network event log server for tracking by the operator.
