Overview of the MGX 8260 Media Gateway

The MGX 8260 Media Gateway is a full-scale, carrier-grade platform with high-performance,

high-density termination and switching of voice, and data traffic over circuit or packet based WANs.

With a modular architecture and interfaces that are compatible with a wide range of access and

backbone network types, the MGX 8260 Media Gateway accommodates a diverse and changing

communications network.

Features and Benefits

The MGX 8260 incorporates multi-path switching intelligence, a speedy edge switch, and ease of

operation. The following list briefly highlights the features of the MGX 8260 Media Gateway Media

Gateway.

• Offload Dial Traffic and Increase Profitability

The Cisco MGX 8260 is a high-density, carrier-class gateway that intelligently switches TDM and

voice over IP (VoIP) traffic across packet networks to significantly reduce costs, improve

availability, and manage escalating demand. The MGX 8260 can offload TDM and VoIP traffic

across a range of interfaces and backbone networks:

–

Voice services across circuit-switched networks (PSTN/SS7)

–

Dial traffic offloading for cost-effective wholesale delivery to Internet service providers

–

TDM to VoIP gateway

By offloading dial traffic directly to network access servers, the MGX 8260 eliminates long

hold-time calls from your TDM network, thereby freeing costly TDM ports for voice calls. The

MGX 8260 maximizes revenue-generating TDM services, reduces total cost of ownership by

improving data transport efficiency, and lays the foundation for a New World IP+ATM

infrastructure that delivers tomorrow's value-added services.

• Leverage High Density and High Performance

With the highest density in the industry, the MGX 8260 media gateway scales from 384 ports to

more than 70,000 TDM ports in a seven-foot telco rack. More than 20 racks of traditional circuit

switching equipment would be required to provision the same number of ports as one MGX 8260

gateway. The MGX 8260 scales up as necessary, when necessary, for rapid time to revenue.

By using advanced digital signal processing (DSP) design, RISC processing, and patented

technology for pipe- lining voice packets, the MGX 8260 also delivers unmatched gateway

performance. Choose from 5 Gbps to 15 Gbps of switching power with the system's
