  • Details

    The Cisco® I-Flex approach combines shared port adapters (SPAs) and SPA interface processors (SIPs), providing an extensible design that helps prioritize data, voice, and video 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. This data sheet contains the specifications for the Cisco 8-Port Channelized T1/E1 Shared Port Adapter (SPA; refer to Figure 1).

    Product Overview

    Today's global enterprise and service provider networks require diverse networking solutions to meet both economic and evolving connectivity needs. The demand for high-density, cost-effective solutions increases as corporate intranets expand to include more regional offices and increased numbers of remote and mobile users.
    The Cisco 8-Port Channelized T1/E1 SPA provides one of the greatest densities currently offered in the industry at 8 ports per SPA and up to 32 ports per SIP. At a cost per T1/E1 port less than that of a standard serial port with external channel service unit/data service unit (CSU/DSU), the Cisco 8-Port Channelized T1/E1 SPA is cost-effective for all WAN connectivity.
    The SPA is designed to provide a full 8-port channelized solution for the Cisco 6500,7600 and the 12000 Series Routers. The interfaces can be channelized, fractional, or unframed (E1) with up to 256 independent High-Level Data Link Control (HDLC) channels definable for T1 and E1 applications. With these capabilities, the SPA eliminates the need for separate interface types for separate connection requirements.
    Multilink Point-to-Point Protocol (MLPPP) is supported (in hardware) to enable link aggregation greater than T1 capacity. Up to eight individual T1s can be combined within a multilink bundle that appears to be a single IP link. This enables service providers to provision greater-than-T1 bandwidth incrementally, without requiring migration of the circuit and customer premises equipment (CPE) infrastructure to T3 facilities.
    The Cisco 8-Port Channelized T1/E1 SPA is hot-swappable and supports service-transparent online insertion and removal (OIR), allowing removal of the SPA without impacting the interface processor and other SPAs.


    The Cisco 8-Port Channelized T1/E1 SPA is ideal for service providers and large enterprises looking to cost-effectively deploy high-density terminations of multiple remote sites (Figure 2). The SPA helps enable applications that require remote and branch-office locations to be terminated on a single router in a corporate enterprise network. For service provider applications where only DSU functions are required (for example, at sites colocated with a carrier), the Cisco 8-Port Channelized T1/E1 SPA provides high port density at a reduced cost per port. For E1 applications, the channelized E1/G.703 interface allows direct connectivity to 120-ohm G.703 lines.

    Features and Benefits

    The Cisco 8-Port Channelized T1/E1 SPA offers many advantages, including:

    • Eight software-configurable T1 or E1 ports

    • Support for channelized and fractional T1/E1, and clear channel E1

    • 256 independent HDLC channels

    • Integrated CSUs/DSUs

    • Support for all major encapsulations, including MLPPP and multilink Frame Relay (MLFR)

    • Support for link fragmentation and interleaving (LFI) over Frame Relay and MLPPP

    The Cisco SPA/SIP portfolio offers the following additional advantages:

    • Modular, flexible, intelligent interface processors

    – Superior flexibility, supporting a combination 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 supports intelligent service delivery without compromising on performance

    • Increased speed-to-service revenue

    – The scalable, programmable Cisco architecture extended to 10 Gbps 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 roll out new services more quickly, helping ensure that all customers, large and small, receive consistent, secure, and guaranteed services.

    – High-density Small Form-Factor Pluggable (SFP) interfaces are featured for high-port-count applications with reach flexibility. Future optical technology improvements can be adopted using existing SPAs.

    • Dramatically improved return on your routing investment

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

    – The ability to easily add new interfaces as they are needed facilitates a "pay-as-you-grow" business model.

    – 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.
