What should I set the CPE default user name and password to?

When the CDRouter ACS needs to communicate with the CPE’s TR-069 client, it will attempt to initiate a new CWMP session using the CPE Connection Request URL. CDRouter will use the username and password specified by the acsCpeDefaultUser and acsCpeDefaultPassword testvars when trying to access this URL. For example, a CPE with a default username of cpeurl and password of cpe123 would be configured as follows:

testvar acsCpeDefaultUser cpeurl
testvar acsCpeDefaultPassword cpe123

If the testvar acsDeviceDiscovery is set to yes, CDRouter can automatically set the CPE Connection Request URL username and password during the first CWMP session. This will ensure that the username and password match.
