The Cisco® I-Flex design combines shared port adapters (SPAs) and SPA interface processors (SIPs), leveraging an extensible design that enables service prioritization for voice, video and data services. Enterprise and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership.

Product Overview

The Cisco 7600 SIP-200 helps enable high-performance, intelligent WAN services. Enterprises and service providers can take full advantage of the increased scalability, performance, and rich features offered by the Cisco 7600 SIP-200, along with the many options for WAN aggregation and connectivity offered in the Cisco SPA/SIP portfolio. The Cisco 7600 SIP-200 provides feature parity with the Enhanced FlexWAN while offering twice the performance and increased scalability.

Cisco 7600 Series Routers offer innovative, next-generation converged services for enterprises and service providers. Built on foundation technologies such as security, QoS, and high availability, the Cisco SPA/SIP portfolio helps enable the delivery of these value-added services for new revenue streams.

The Cisco 7600 SIP-200 is supported both on Cisco 7600 platform and Catalyst 6500 platform.


Ideal for enterprise headend and service provider edge aggregation, the Cisco 7600 SIP-200 supports up to 622 Mbps of bandwidth and numerous interfaces. (Note: Bandwidth is expected to decrease when QoS is enabled.) The innovative architecture of this industry-leading WAN services module delivers Cisco 7500 Series feature parity and feature velocity for time-to-market solutions.

Enterprise and Service Provider WAN Aggregation

The Cisco 7600 SIP-200 helps enterprises and service providers deploy high-density WAN aggregation, based on Frame Relay, Point-to-Point Protocol (PPP), High-Level Data Link Control (HDLC), ATM, or Packet over SONET/SDH (POS). Additionally, service providers can take advantage of the Multiprotocol Label Switching (MPLS) and Any Transport over MPLS (AtoM) options supported on the Cisco 7600 SIP-200 to offer Layer 2 and Layer 3 VPNs. Rich QoS features and distributed processing attributes of the Cisco 7600 SIP-200 make it a cornerstone of a highly scalable WAN aggregation solution. Higher-layer applications can easily be supported on this end-to-end network to allow intelligent data, voice, video, and security services – all on the same platform – to provide integrated, easy-to-use application delivery and control.

Service Convergence and Intelligent Network Services for Next-Generation Applications

The unique value the Cisco 7600 Series provides is the convergence supported from the physical layer to a highly scalable application layer. The Cisco 7600 SIP-200 simplifies network design and deployment by allowing consolidation of LAN, WAN, and metropolitan-area network (MAN) interfaces into a single, highly scalable platform. The Cisco 7600 SIP-200, by integrating WAN termination, rich QoS features, bandwidth optimization, and security on the same module, obviates the need for multiple service modules, offering tremendous cost savings. The rich classification features supported on the Cisco 7600 SIP-200 enable identification of packets from Layer 2 to Layer 7 of the OSI model, enabling application-level intelligence and security in the network.

Features and Benefits

The rich QoS features of the Cisco 7600 SIP-200 enable users to:

   Classify and mark packets for QoS treatment within the network

   Deliver bandwidth to business-critical applications

   Limit bandwidth to non-critical applications

   Avoid network congestion by dropping select low-priority packets

   Smooth out bursts and avoid packet discard in the network

In addition, low-speed WAN aggregation features supported include:

   Compressed Real-Time Protocol (cRTP) to maximize bandwidth utilization

   Distributed link fragmentation and interleaving (dLFI) to minimize jitter

   Multilink PPP (MLPPP), Multilink Frame Relay Protocol (MLFR), ATM VC Bundle, and Frame Relay VC Bundle to bundle multiple low-speed links

Table 1 summarizes the features and benefits of the Cisco 7600 SIP-200.

     Unmatched flexibility, providing mix-and-match of interface types on the same interface processor for consistent services, independent of access technology.

     Pioneering programmable interface processors that provide flexibility for the service diversity required in next-generation networks.

     Innovative design that provides intelligent delivery of services without compromising on performance.

   Increase speed to service revenue

     The future-proof programmable Cisco architecture extended to 10 Gigabits per second dramatically improves customer density, increasing potential revenue per platform.

     Interface breadth (copper, channelized, POS, ATM, and Ethernet) on a modular interface processor allows service providers to more quickly roll out new services, ensuring all customers large and small receive conistent, secure, and guaranteed services.

     High-density SFP interfaces are featured for high-port-count applications with reach flexibility. Future optical technology improvements can be adopted using existing SPAs.

   Dramatically improve the financials of your routing purchase

     Improved slot economics and increased density reduce capital expenditures (CapEx).

     The ability to easily add new interfaces as they are needed enables a "pay-as-you-grow" business model while still offering a high-density solution.

     SPAs are shared across multiple platforms, and can be easily moved from one to another, providing consistent feature support, accelerated product delivery, and a significant reduction in operating expenses (OpEx) through common sparing as service needs change.
