Chapter 1 Overview of the MGX 8260 Media Gateway
Managing the MGX 8260 Media Gateway
interchangeable switch fabrics. At the same time, ensure the lowest possible network delay. The
MGX 8260 limits delay to 40 milliseconds (between two MGX 8260 gateways) for VoIP
packetization/ de-packetization.
• Maximize Service Availability
The MGX 8260 provides the industry's highest availability—99.999 percent—to ensure that your
customers enjoy always-on service. A redundant architecture and hot-swappable modules eliminate
single points of failure. The MGX 8260 provides built-in 1:1 redundancy on all high-speed modules
and interfaces, as well as 1:N redundancy for narrowband and DSP resources. The MGX 8260
platform also incorporates a redundant, high-speed hybrid bus design for switching between TDM
and packet services. With no single point of failure, calls in progress are maintained even if the
switch or line cards fail—a significant advantage over TDM switches.
Excellent serviceability also maximizes platform reliability. Technicians have quick and easy
access to the platform via a passive rear panel where network connections attach to physical
interface cards. Seamless software upgrades ensure that new features are added without downtime
or service disruptions.
• Deliver New Services
Based on the Cisco Open Packet Telephony framework, the MGX 8260 interoperates with your
existing technology and transitions smoothly to emerging value-added services. The Open Packet
Telephony framework, an industry-standard open interface, separates the call control layer from the
switching fabric. This open interface integrates the MGX 8260 with your operations support
systems, service creation environments, and media gateway controllers based on the Media
Gateway Control Protocol (MGCP).
The MGX 8260's open interfaces enable you to quickly and cost-effectively develop and deploy
new revenue- generating services. And by moving data streams onto a packet network you not only
add a revenue source, you also are positioned to support New World value-added services—the
cornerstone of future profitability. As new industry-standard networking capabilities emerge, you
will be able to leverage them.
Managing the MGX 8260 Media Gateway
You can manage the MGX 8260 from any of the following interfaces:
• WebViewer
• SNMP
• Command line interface
The MGX 8260 gateway offers multiple levels of security access, including viewing, configuration,
system administration, and super-user control. It also supports configuration file backup and restore, as
well as software upgrades. The following diagram shows the management interfaces and the internal
databases they control (see Figure 1-1).
