• When the private network fails, a Router without device majority goes to the isolated-disabled state and stops processing traffic. in context
• When the private network fails, a Router that has device majority goes to the isolated-enabled state and keeps handling traffic. in context
• When the public path to one Router is lost, PGs realign their data stream to their local Router, which forwards data to the other Router over the private network. in context
• Duplexed UCCE sides exchange private-network heartbeats every 100 ms in both directions. in context
• If either side misses heartbeats for five times the heartbeat period, it assumes the private link or peer has failed. in context
• In a split public-network failure where an agent's phone is registered on the far side of the Unified CM cluster, Unified CCE can no longer direct calls to the phone and automatically signs the agent out. in context
• Public-network heartbeats between each PG and the Central Controller run every 400 ms in both directions. in context
• During a private network failure, the pair-disabled Router side tells its enabled PGs to contact the other Router over the public network to test that side's status. in context
