CWMP mechanism

Autoconnection between an ACS and a CPE
When a CPE starts up for the first time, it automatically obtains an IP address from the DHCP server,
which informs the CPE of the following information:
The URL address of the ACS (assigned by the DHCP server through Option 43)
•
Username and password for connecting the ACS (assigned by the DHCP server through Option 43)
•
• DNS server address (directly assigned)
After the CPE receives this information, it has the IP address of the ACS resolved by the DNS server, and
sends a connection request to the ACS. If the CPE passes the authentication with the acquired username
and password, the connection between the ACS and the CPE is established.
If the current session is not finished but the connection between ACS and CPE is interrupted, the CPE
automatically establishes a new connection with the ACS until the number of CPE auto-connection retries
reaches the limit.
