Subscriber Interfaces
Subscriber interfaces are composed of a combination of two key technologies, subscriber inter-
faces and group interfaces. While the subscriber interface defines the subscriber subnets, the group
interfaces are responsible
for aggregating the SAPs.
• Subscriber interface — An interface that allows the sharing of a subnet among one or
many group interfaces in the routed CO model.
• Group interface — Aggregates multiple SAPs on the same port.
• Redundant interfaces — A special spoke-terminated Layer 3 interface. It is used in a
Layer 3 routed CO dual-homing configuration to shunt downstream (network to
subscriber) to the active node for a given subscriber.
