The eight-port IMA module on the Catalyst 8500 MSR and LightStream 1010 (with FC-PFQ) provides a low cost solution when T3/E3 services are either cost-prohibitive or unavailable. These new modules complement the existing OC-12c/STM-4, OC3c/STM-1, DS3/E3, and T1/E1 ATM network modules available for the Catalyst 8500 MSR and LightStream 1010. The high cost and limited availability of broadband ATM services have prevented many organizations from deploying ATM quality-of-service (QoS) features to remote locations and branch-offices. These locations typically require bandwidth that ranges from a few T1 or E1 circuits to eight T1/E1 circuits. All eight ports on the IMA module supports all ATM Forum adaptation layers (AAL) and ATM QoS categories: unspecified bit rate (UBR), real-time variable bit rate (VBR-rt), non-real-time variable bit rate (VBR-nrt), available bit rate (ABR), and constant bit rate (CBR). Integrating ATM forum standards-compliant IMA into large, small, and medium-size networking platforms, Cisco now provides enterprise users and service providers a complete family of solutions for LAN-to-WAN, branch- office, campus and ATM edge applications, combining data, voice, and video with ATM guaranteed QoS features.
