Access Node Control Protocol Management (ANCP) can provide the following information to the router:
ANCP can communicate the current access line rate to the router. This allows the router to adjust the H-QoS subscriber scheduler with the correct rate or potentially change alarm when the rate goes below a set threshold. This allows a policy manager to change the entire policy when the rate drops below a minimal threshold value. The ANCP actual upstream synchronization rate is mapped to the ingress while ANCP actual downstream synchronization rate is mapped to the egress.
The router can send DSL line OAM commands to complete an OAM test from a centralized point or when operational boundaries prevent direct access to the DSLAM.
When ANCP is used with ESM, the ancp-string string can be returned from the Python script or from RADIUS. If not returned it defaults to the subscriber ID.
ANCP version 0x31 and 0x32 are both supported and are autodetected at the start of each ANCP session. Within version 0x32, partitioning is also supported.
Multiple partitions from the same access node are also supported. If partitions are used, they are automatically detected during the start of an ANCP session.
