The Cuda™ 12000 N+1 HFC Redundancy provides cable operators and subscribers with the required protection for today's video, voice and data services. This critical feature includes a field replaceable RF switch that supports up to nine working HFC interface modules and one protect module. An enhanced HFC interface module is required for protection. The Cuda 12000's protection also includes redundant network interface modules and redundant management modules.

Features:

• Hot-swappable RF switch dramatically reduces mean time to repair (MTTR) while improving system mean time between failure (MTBF)
• Enables hitless upgrades providing seamless transitions to new software versions
• One module protects up to nine working modules, minimizing the cost of redundancy
• CableOnce™ allows module replacement without removing a single cable, significantly reducing MTTR
• Self-test feature enables periodic testing to assure switch readiness in the event of a failover

N+1 HFC Redundancy Option - Main Components

Metal frame

Attaches to rear of the Cuda 12000 chassis and houses the N+1 backplane and rear I/O cards.

N+1 backplane

Provides module interconnection to enable N+1 protection switching.

Protection rear I/O module

Completely passive rear I/O module for the protect (standby) HFC interface module in an N+1 redundancy group.

Working rear I/O module

Completely passive rear I/O module for the working application modules.

Upstream switch card

Each card supports protection switching for up to two upstream channels.

Downstream switch card

Supports protection switching for one downstream channel.

Power processor card

Provides power conversion and control to the upstream and downstream switch cards.
