The Cisco 3270 Rugged ISR can be used in a variety of applications. The following are a few deployment scenarios.

Mobile Networks

The Cisco 3270 Rugged ISR establishes a mobile, broadband network in vehicles, helping public safety, transportation, and defense customers extend their corporate resources securely to employees in the field. The Cisco 3270 offers a scalable network platform, establishing a mobile network for first responder vehicles, armored vehicles, and commercial and freight rail trains.
To ensure transparent connectivity to the roaming vehicle network, Cisco has integrated standards-based Mobile IP software into the Cisco IOS Software running on the Cisco 3270. Mobile IP allows transparent roaming over multiple wireless networks. For example, cellular, satellite, or global-positioning-system (GPS) modems can be connected to the Cisco 3270 to provide multiple wireless network connections to the vehicle network.

Embedded Outdoor Networks

The Cisco 3270 Rugged ISR can be inserted into outdoor infrastructure to extend IP networks to outdoor locations. Qualified system integrators can embed the Cisco 3270 into existing outdoor infrastructure such as traffic signal control boxes, telephone booths, or utility substations to tie remote networks into a manageable, highly secure IP network. For example, the Cisco 3270 provides a high-performance router for aggregating peripheral devices onto an IP network, including video surveillance cameras and chemical sensors. In more remote areas, the Cisco 3270 can be embedded into utility substations and can integrate proprietary networks on to an IP network for greater operational efficiency.

On-Demand Network Connectivity

The Cisco 3270 Rugged ISR can be used to provide on-demand network connectivity for homeland security and emergency response applications. In disaster situations, regular network connectivity is often not available because of damaged network infrastructure or lack of network capacity. Federal response teams or tactical military teams must have a versatile network platform that has the following characteristics:

• Flexible form factor with high performance

• Portability

• Low power consumption

• Ability to handle harsh environments

The Cisco 3270 platform is versatile because it can be purchased as a standalone router card or as a fully enclosed rugged router preconfigured from Cisco. System integrators can also embed the Cisco 3270 into their own enclosures or travel kits. These on-demand kits are embedded in small transit cases, suitcases, or hardened enclosures for ease of portability.
