Setting up a Frame Relay Connection

“B,” is attached to the other MGX 8220 shelf. This chapter describes how a Frame Relay connection can be established to permit bidirectional communication between the Frame Relay equipment at “A” and “B.”

To make the connection, the path from “A” to “B” is made up of three segments as shown in Figure 5.2. When using the CLI, each segment must be established and configured separately.

Two segments span from the FRSM to the BNM on the MGX 8220 shelves. These segments are part ATM and part Frame Relay with the conversion being made in the MGX 8220 shelves.

There is also an ATM trunk segment that spans the BPX backbone network from one of the BPX nodes to the other BPX node, this segment terminates on a BNI feeder trunk in each node. This segment may include intermediary BPX nodes (not shown in the diagram).

The links between the segments must be configured properly so that the three segments make up one complete end-to-end connection from “A” to “B.” This process consists primarily of ensuring that the VPI between the MGX 8220 shelf and its co-located BPX switch must contain the MGX 8220 slot number of the FRSM and the VCI must contain the logical channel number assigned to the virtual circuit.

Establish the Customer Equipment to BPX Segments

This procedure must be performed on the MGX 8220 at BOTH ends of the connection (“A” and “B”).

To establish an end-to-end Frame Relay connection, perform the following steps:

Step 1 On the MGX 8220 shelf, log in to the FRSM that is to be used for the Frame Relay connection.

Step 2 If not enabled, enable the T1 line to be used for the Frame Relay connection by entering the addln command using the physical FRSM connector number (1 to 4) connected to the T1 line.

Step 3 If not configured, configure the T1 line to the Frame Relay equipment by entering the cnfln command. Specify parameters as appropriate.

Step 4 If not enabled, enable the port to the Frame Relay equipment by entering the addport command using the parameters as follows:

For port number, specify an unused port number (1 to 96).

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.
