4.1 CWMP Overview

CWMP defines a communication mechanism between CPEs and ACSs, and allows an ACS to
manage CPEs in a uniform manner.
Introduction to CWMP
The CPE WAN Management Protocol (CWMP) is drafted by the Digital Subscriber's Line (DSL)
forum. It is also called TR-069 standard. CWMP is applicable to DSL networks. On a DSL
network, device management is difficult because there are many user-side devices distributed
at different locations. CWMP defines that the customer premises equipment (CPE) is remotely
managed by an auto-configuration server (ACS). CWMP facilitates CPE management, reduces
maintenance and operation costs, and improves troubleshooting efficiency.

manage it. During connection setup, the CPE or ACS needs to be authenticated. The connection

DHCP Server
IP Network
ACS: manages and maintains CPEs on the network.
CPE: managed by the ACS.
DNS server: defines that an ACS and a CPE use URL to identify and access each other.
DNS resolves the URL.
DHCP server: assigns IP addresses to ACSs and CPEs, and sets parameters for CPEs by
using the Options field in DHCP packets.
