Cisco Catalyst 8400 Series

The Catalyst 8400 series wide−area switches provide the backbone services to deliver data, voice, fax, and video applications. The IGX 8400 series integrates with other Cisco WAN products to offer end−to−end solutions. The Catalyst 8400 series integrates several QoS features, including:

∙Automatic routing management—The switches perform a connection admission control (CAC) function on all types of connections in the network. Distributed network intelligence enables the CAC function to automatically route connections over optimal paths while guaranteeing QoS.

∙Dynamic buffer management—The switch dynamically assigns buffers to individual virtual circuits based on the amount of traffic and service−level agreements.

∙Optimized bandwidth management—The 8400 switch guarantees fair and cost−efficient bandwidth utilization using various techniques such as voice compression and Voice Activity Detection (VAD) for voice, and Repetitive Pattern Suppression (RPS) for circuit−switching data traffic.

Catalyst 8400 Modules

The Catalyst 8400 series is available with 8 slots on the 8410, 16 slots on the 8420, and 32 slots on the 8430. These switches use a 1.2Gbps redundant cell bus. They support a wide array of modules for OC−3/STM−1 ATM interfaces, T3/E3 ATM interfaces, T1/E1 Frame Relay interfaces, V.35 Frame Relay interfaces, X.21 Frame Relay interfaces, HSSI Frame Relay interfaces, EIA/TIA−232 circuit data interfaces, and one− or two−port voice modules using either T1, E1, or J1.

Catalyst 8400 Services

The Catalyst 8400 series offers standards−compliant ATM user−to−network interface/network−to−network interface on a variety of interfaces. All ATM interfaces support per−VC queuing, rate scheduling, and multiple classes of service including those defined by the ATM forum, such as constant bit rate (CBR), variable bit rate real time (VBR−RT), variable bit rate non real time (VBR−NRT), available bit rate (ABR), and unspecified bit rate (UBR). It also offers ATM interfaces that can be customized to meet performance requirements.

The advanced traffic management features of the Catalyst 8400 series enable built−in congestion avoidance mechanisms for Frame Relay traffic. Standards−based messaging on the user−network interface (UNI) enables the Catalyst switch to extend traffic management features to Cisco routers, delivering high QoS across the entire Frame Relay network. Enhanced Local Management Interface (ELMI) also enables automatic Frame Relay traffic−shaping parameter configuration on Cisco routers.

Cisco’s Tag Switching technology provides you with a highly scalable, reliable means of integrating IP traffic with ATM traffic.

The Catalyst 8400 switch offers efficient, high−quality voice connectivity across the wide−area backbone. All voice interfaces can be directly attached to voice switches for voice or fax/data connectivity via a T1/E1 interface. The Catalyst 8400 series voice interfaces support standards−based voice compression schemes and onboard echo cancellation. Voice compression reduces the amount of bandwidth required for voice connections across the WAN. The Catalyst switch supports the following voice compression techniques:

∙Adaptive Differential Pulse Code Modulation (ADPCM) at 16Kbps, 24Kbps, and 32Kbps
