The PRIs are then freed for other revenue-generating services because they are no longer needed to connect the gateways. Figure 1 illustrates the Cisco SC2200 node architecture. The Cisco SC2200 software operates on a pair of Sun hosts for maximum availability and reliability. This checkpointing, along with main memory database synchronization, enables switchover from active host to standby host with no disruption of stable calls. The Cisco SC2200 is capable of supporting 90,000 calls on a single pair of redundant hosts.
Nodes can be nationally, regionally, or locally deployed.
Others control many remote access servers and voice gateways from their operations center. Signaling Link Terminal Maintaining the SS7 signaling links is critical to being part of the SS7 network. Cisco 2611 multiservice access router platform. Link sets are terminated across multiple SLTs to eliminate single points of failure. Cisco SC2200s are currently deployed in European, Asian, Australian, North American, and Latin American markets.
