Masive Provisioning
However, if could happen that the technician that designed these configurations made a mistake, and designed a SetParameterValues to configure the same parameter twice with different values. TR-069 A.3.2.1 specifies that in this case, the CPE should not modify any of the parameters included in the SetParameterValues, instead, it should return an error. If the protocol is not correctly implemented in the CPE and the CPE does not return an error, it will be unknown which of the two different values has been applied in the CPE, since there is not a specific order established that the CPE should follow to apply changes sent in the same SetParameterValues.
The case of incorrect provisioning
This is an example where a router shows an error in test 5.58 from ATP-069. This test case has been designed to detect this problem. dBm069 shows that this test has failed:
When selecting this test case, the "Execution Datails” window shows that an error has been detected when the ACS sends the SetParameterValues, and also when reading the values afterwards with the GetParameterValues.
Clicking in this window on the SetParameterValues line, we can see at the "Test Log” window that a SetParameterValues has been sent trying to configure the same parameter twice with different values
The details of the SetParameterValuesResponse show that the CPE has accepted the SetParameterValues, instead of reporting an error:
The CPE should not have modified the values of any of the parameters sent in that SetParameterValues. The next GetParameterValuesResponse shows that the parameters have been modified. This is an error in the implementation of TR-069 protocol in the CPE that can cause interoperability problems.
OPERATING CONSEQUENCES
An unfinished configuration would leave the CPE in a total or partial non-functional status.
The result of an unfinished configuration in the CPE could thus mean:
The result of an unfinished configuration in the CPE could thus mean:
- if the ACS is configuring the WLAN, an unfinished configuration could cause the loss to the access to the internet via WIFI
- if the ACS is configuring VoIP parameters, an unfinished configuration could cause the user’s loss of the telephone connection
- if the ACS is configuring a STB, an unfinished configuration could cause the loss of TV signal
- if the ACS is configuring an AccessPoint, an unfinished configuration could cause to leave it in a non-operational state
- if the ACS is opening a port, an unfinished configuration would result in a non-open port
- An unfinished configuration could also leave the CPE in a blocked state where it could be necessary to perform a manual FactoryReset to allow it recovering.
