This attribute when set to 'true' triggers the change-over operation for Externally-Directed Load Balancing. Setting this attribute to 'true' is known as a commit operation. A commit operation is considered successful if the CMTS considers that the entered information is valid and the transaction can be initiated. It does not imply that the channel-change operation itself (i.e. UCC, DCC, DBC transaction) reports success or completion. A commit operation is considered unsuccessful if the CMTS determines that there are invalid attributes values in the ChangeOver object such that the change-over operation cannot be initiated. Some examples for a change-over that cannot be initiated are: - Attempt to send a DBC for MRC that does not fit the CM RCP. - Attempt to send a DCC while a previous one is still in progress. - Attempt to send a UCC to a channel ID that is not defined. After system initialization all ChangeOver object parameters are set to default values. After a successful commit operation all ChangeOver object parameters are set to default values with the exception of this attribute (commit) that is set to 'true'. An unsuccessful commit operation is rejected and this attribute reports false in subsequent value queries. After a successful commit operation, the CMTS initiates the change-over transaction using the most appropriate technique. The potential techniques are: - UCC - For upstream-channel-only changes on CMs not operating in MRC mode. - DCC - For upstream and/or downstream channel changes on CMs not operating in MRC mode. - DCC followed by channel assignment in REG-RSP-MP - For MAC Domain re-assignment on CMs operating in MRC mode, as well as upstream only change for CMs operating in MRC mode but with no TCS conveyed during registration. In this case, the change-over command might only include a downstream frequency, or might include an RCC defined in the target MAC domain. The upstream channel set may or may not be provided. The only applicable Initialization Technique for this operation is 'reinitializeMAC'. - DBC - For change in the TCS and/or RCS on CMs operating in MRC mode.
