MD5 digest authentication is used for connections between the CPE and central
office TR-069 management equipment, and the authentication complies with TR-069
Amendment 4.
When TR-069 network management is enabled, each registration of the CPE will
generate about 70 KB of data traffic, each periodic reporting will generate about 20 KB
of data traffic, and the data traffic generated by each update depends on the update
package size. An update package is generally smaller than 100 MB, and updates are
triggered by the central office management equipment.
When TR-069 network management is enabled, the CPE regularly connects to the central
office management equipment, and the connection cycle complies with TR-069
Amendment 4.
Digest authentication prevents the account and password used for connections between
the CPE and central office TR-069 management equipment from being cracked. The
number of attempts is five. After five attempt failures, wait five minutes and receive new
connection authentication requests.
