H8238

The Cisco MGX 8220 IP+ATM edge concentrator offers a wide range of services in a single, compact aggregation shelf. This enables service providers to build an integrated multiservice network to deliver Frame Relay, ATM, and private line services. By concentrating narrowband traffic over a wide-area ATM network backbone, the Cisco MGX 8220 reduces equipment costs and makes efficient use of trunking resources. This protects a service provider’s investment in equipment and allows the rapid deployment of new services as required.

Configuration Examples

The Cisco MGX 8220 edge concentrator can be used to concentrate services for a Cisco BPX 8600 series switch either from a local or remote location. The Cisco MGX 8220 can also be used as a stand alone edge concentrator.

Cisco BPX 8600 Series Switch

When configured as part of a Cisco BPX 8600 series wide-area switch, the Cisco MGX 8220 edge concentrator allows modular scaling of the service node capacity without requiring additional switches. All Cisco MGX 8220 edge concentrator shelves in a service node are logically managed as an integrated part of the service node.

Each Cisco MGX 8220 shelf connects to the Cisco BPX switch across one of the following:

•T3 or E3 ATM to a BNI or T3/E3 BXM module

•SMF SONET ATM link to a BXM-155-8 port or BXM-155-4 port

MGX 8220 specifications

The Cisco Systems MGX 8220 is a versatile, high-performance media gateway that has become an integral component in the telecommunications infrastructure. Designed to facilitate the transition from traditional circuit-switched networks to advanced packet-switched environments, the MGX 8220 supports a wide array of voice, video, and data services, making it an essential tool for service providers and enterprises seeking to enhance their network capabilities.

One of the key features of the MGX 8220 is its robust signaling and media processing capabilities. Equipped with support for both Voice over IP (VoIP) and traditional telephony protocols, this gateway enables seamless integration of different communication formats. It boasts a modular architecture, which allows for the addition or removal of various line cards to meet changing demands and technology advancements. This modularity provides operators with the flexibility to scale their services without significant overhauls to their existing infrastructure.

The MGX 8220 is capable of delivering high-density media handling for a multitude of services. With its support for ATM and IP networks, the gateway can handle TDM (Time-Division Multiplexing) to packet voice conversions efficiently. It is designed to optimize network resources by dynamically allocating bandwidth based on traffic requirements, thus ensuring efficient use of network resources and improved performance.

Another significant characteristic of the MGX 8220 is its enhanced quality of service (QoS) features. This capability ensures that voice and video traffic is prioritized appropriately, minimizing latency and jitter while maximizing overall call quality. By employing sophisticated traffic management techniques, the MGX 8220 can deliver a superior user experience, which is critical for any service provider aiming to offer competitive communication solutions.

Furthermore, the gateway includes built-in security features to protect against unauthorized access and ensure the integrity of sensitive data. This includes encryption for voice and video transmission, as well as support for secure signaling protocols.

Overall, the Cisco Systems MGX 8220 stands out as a comprehensive media gateway solution, providing essential functionalities for modern communication needs. Its combination of modularity, high-density processing, effective QoS management, and security features makes it a compelling choice for organizations looking to modernize their telecommunications infrastructure while ensuring reliability and performance. As businesses continue to evolve and demand more from their networks, the MGX 8220 offers a pathway to future-ready communications.
