TR-069




TR-069는 DSL Forum에서 정의한 CPE WAN Management
Protocol (CWMP)이다
CWMP는 CPE (Customer Premise Equipment) 와 ACS (AutoConfiguration Server)사이에서 ACS가 CPE의 설정, 업그레이드 등
을 관리할 수 있도록 조정자 역할을 하게 해준다.

TR-069 Connection Establishment


The CPE establishes a connection to the ACS on a number of occasions:











The first time it is installed/connected
On startup
Periodically
When requested by the ACS
Whenever particular parameter values change (via Connection Request)
When a file transfer is complete (e.g. after firmware upgrade)
When a diagnostics test is complete

On each connection establishment, the CPE sends the Inform RPC to the
ACS which contains the reason/event for the connection establishment.
