Establishing the Cisco MGX 8220 to Cisco BPX Connection

Each CLI command and its syntax and privilege level is provided in the Cisco MGX 8220 Command

Reference.

Establishing the Cisco MGX 8220 to Cisco BPX Connection

This procedure must be performed on the Cisco BPX at both ends of the connection (“A” and “B”). This connection is established only once per shelf.

On the Cisco BPX

1.Enter the uptrk command to enable the T3 line that connects to your Cisco MGX 8220 shelf. For trunk number, specify the BNI trunk number used for the Cisco MGX 8220 T3 line.

2.Enter the cnftrk command.

This command configures the physical line parameters of the T3 line connecting the BNI in the Cisco BPX switch and BNM in the Cisco MGX 8220 shelf. Refer to the Cisco WAN Switching Command Reference for details.

3.Enter the addshelf command to enable the port to the Cisco MGX 8220 shelf.

For trunk number, specify the BNI trunk number used for the Cisco MGX 8220 T3 line. For shelf-type, specify “A” for Cisco MGX 8220, specify the VPI (between 5 and 14) and VCI (between 6 and 271) in the VPI and VCI fields.

Note The total number of cells for all queues should not exceed 10,000.

Cisco MGX 8220 Management Through SNMP

The Cisco MGX 8220 shelf provides the ability to manage the shelf through Simple Network Management Protocol (SNMP) commands. These commands are issued from an SNMP Manager, which accesses the Cisco MGX 8220 shelf either through the Ethernet port, the control port, or in-band connection.

Each ASC and service module in the shelf contains an SNMP agent and a Management Information Base (MIB) for that module. The SNMP agent responds to GET, GET NEXT, and SET commands from the SNMP Manager, thereby providing the user with the ability to interrogate and update the MIB.

All messages from the SNMP manager are checked for the correct community string as follows:

•Messages to the active ASC must have a community string of AXIS_ASC_ACTIVE

•Messages to the standby ASC must have a community string of AXIS_ASC_STANDBY

•Messages to service module must have a community string of AXIS_SM-xx(where xx is the service module slot number 5 to 14)

•Messages to the active BNM must have a community string of AXIS_BNM_ACTIVE

•Messages to the standby ASC must have a community string of AXIS_BNM_STANDBY

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.
