Cisco 7600-SIP-400 Cisco 7600 Series SPA Interface Processor-400 High-Performance Cisco 7600 SIP-400 Interface Processor for Scalable WAN and Service Aggregation The Cisco 7600-SIP-400 SPA Interface Processor is a high-performance modular interface processor designed for Cisco 7600 Series routers, enabling scalable WAN, MAN, and multiservice network deployments. Built for carrier-grade environments, it provides flexible interface expansion and efficient traffic management for converged data, voice, and video services. Supporting up to 4 Shared Port Adapters (SPAs), the 7600-SIP-400 allows organizations to deploy a wide range of interfaces, including Ethernet, POS, ATM, circuit emulation (CEoP), and WAN/MAN connectivity modules. This flexibility makes it ideal for service providers and enterprises managing diverse network infrastructures. With an aggregate bandwidth capacity of approximately 2.5 Gbps, the module delivers reliable high-speed packet processing and advanced Quality of Service (QoS) capabilities. Features such as traffic shaping, hierarchical queuing, and policing ensure optimized performance for latency-sensitive applications and converged network services. Designed for high availability, the 7600-SIP-400 supports Online Insertion and Removal (OIR), enabling hot-swappable replacement and upgrades without disrupting network operations. Integrated support for MPLS and advanced routing services allows seamless deployment in enterprise core and service provider edge environments. Running on Cisco IOS, the interface processor integrates seamlessly with Cisco 7600 Series architectures, providing scalable and dependable performance for mission-critical networks. Ideal for service provider WAN aggregation, metro Ethernet deployments, enterprise edge routing, and migration from legacy TDM to packet-based networks, the Cisco 7600-SIP-400 delivers a flexible, scalable, and carrier-grade solution for modern multiservice networking.
