- Distribution backbone: IP over FDDI, 100baseT, ATM (OC3).
- Scale from low-penetration, decouple up/down:
- Forward: start one mod for all users, install additional cards.
- Reverse: start RF-limited FN clusters, additional demods as needed by traffic growth..
- Support important IP features:
- IP filtering.
- Multicasting/broadcasting.
