MGX 8220 in Stand-alone Applications

A stand-alone application is defined as one in which the MGX 8220 shelf is connected to some device (router or ATM switch) other than a BPX 8620.

The interface between MGX 8220 shelf and the connected device must be ATM UNI/NNI over either T3, E3, nxT1, nxE1, or OC-3c as shown in Figure 6-1.

This chapter provides guidance in those areas of configuration that are peculiar to the stand-alone configurations.

•Using the command-line interface

•Disabling the ILMI interface

•Configuring the BNM ATM interface to the router or ATM switch

•Setting trap managers

•Understanding DLCI to VPI/VCI mapping in the MGX 8220 shelf (for purposes of configuring the router or ATM switch)

•Provisioning Frame Relay and other channels in the stand-alone MGX 8220 shelf.

This chapter makes reference to the MGX 8220 command-line interface (CLI) commands. Details of these commands are found in the Cisco MGX 8220 Command Reference.

Using the Command-Line Interface

A stand-alone MGX 8220 shelf cannot be configured from CWM and must be configured using the MGX 8220 CLI. This may be achieved either through an in-band connection over the ATM link, or through one of the out-of-band options (maintenance, control, or Ethernet ports on the ASC).

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.
