Fault tolerant architecture maintains services
through almost any failure
• Redundancy protection for key modules: N:1 protection
for the CBX 3500™ Universal Input/Output Module
and 1+1 Automatic Protection Switching
(APS)/Multiplex Section Protection (MSP) on
SONET/SDH interfaces help support non-service
impacting upgrades and protect against card failures.
• Routing and signaling protection: Distributed routing
and signaling control help avoid single points of
failure. If a network or service disruption occurs,
priority-based routing of hundreds of thousands of
circuits per second quickly restores services.
• Reliable architecture: Fully redundant hardware,
control, and power components protect against
hardware failures and reduce network downtime. If a
failure occurs, automatic failover, Stratum 3 holdover
timing, and hot-swappable modules can restore
services quickly without losing data.
