The MGX 8250 is designed for carrier-class reliability. System components can be configured for 100 percent redundancy, and all MGX 8250 modules can be removed and reinserted without impacting service delivery or affecting the performance of other modules. Hot-standby interfaces offer optional redundancy so that if a module fails, the standby is fully online within milliseconds. Switchover to standby interfaces is nonservice-affecting for most protocols, ensuring nonstop application performance. The MGX 8250 Edge Concentrator supports industry-standard, automatic protection switching (APS) for all SONET and synchronous digital hierarchy (SDH) interfaces using the 1+1 APS scheme. In the event of a fiber cut or card failure, APS performs switching to the backup fiber within milliseconds. The MGX 8250 provides 1:N redundancy of service interfaces to enhance overall reliability and availability. With support for 1:N redundancy, a single standby Service Module will automatically take over the traffic functions of any failed Service Module of the same type within seconds. |
