FRASM Connections

Via the Command-Line Interface

Setting up a CESM connection is performed through the command-line interface (CLI). The procedure is to first add the line entering the add line command (addln) and then add and configure a channel entering the add channel (addchan) command. In the addchan command the channel number, the cell delay variation, the cell loss integration period, and buffer size are all specified. The command sequence is

1.addln <line #>

2.addchan “chan_num CDV CellLossIntegPeriod bufsize” chan_num -- value ranging from 16 to 19

16 - line 1, 17 - line 2, 18 - line 3, 19 - line 4

CDV -- Cell delay variation: Range 1000-65535 microseconds CellLossIntegPeriod -- Cell loss integration period:

Range 1000-65535 milliseconds

bufsize -- egress bufsize: Min value: 0.6*CDV-T1, 0.7*CDV-E1.

Max value: 65535, 0 to auto-compute

Example:

addln 1

addchan 16 10000 2500 0

FRASM Connections

Use the following procedures to setup an FRASM connection.

Via the Command-Line Interface

Setting up an FRASM connection is performed through the CLI. There are three basic types of connections.

•FRAS BNN connections, which are used to support connections that require an SNA/SDLC interface at one end of the connection and a Frame Relay interface at the other.

•STUN connections, which are used to support connections that require SNA/SDLC interfaces at both ends of the connection.

•BTUN connections, which are used to support connections that require 3270/bisynch interfaces at both ends of the connection.

For more information about these types of connections, see Chapter 4, “MGX 8220 Service Modules,” “Frame Relay Access Service Module” section.

For all three types of connections, the procedure is to first establish a physical line for the connection entering the add line command (addln) in which the physical back card port is specified and then to establish and configure ports on that line entering the add port (addport) command for each port.

In the addport command, the port number, line number, line speed, time slot, the port type, the encoding type, and the interface type are specified.

To complete the connection, additional commands are used that are specific to the type of connection being set up (FRAS BNN, STUN, or BSTUN).

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.
