Two Models Available
The Cisco 3200 Series Mobile Access Router has two models. The Cisco 3250 Mobile Access Router is a configurable
platform with a choice of hardware and software options. The Cisco 3220 Mobile Access Router is preconfigured
and is suitable for mass deployments in commercial transportation and public safety markets.
Hardware Overview
The Cisco 3200 Mobile Access Router combines high performance with small size. Each card of the mobile access
router is roughly the footprint of a 3.5-inch floppy disk, so it can be deployed in places where traditional networking
equipment is inappropriate. The hardware of the Cisco 3200 Mobile Access Router is specially designed for the harsh
operating environment typical of moving or stationary vehicles operating on land, in the air, or by sea.
The Cisco 3200 Mobile Access Router adheres to the PC/104-Plus electrical and mechanical standard. As a
standards-based solution, the Cisco 3200 Mobile Access Router allows for easy and cost-effective integration with
third-party PC/104-Plus products such as a hard disk drive, which would interface through industry-standard ports
on the Cisco 3200 Mobile Access Router.
Cisco 3250 Mobile Access Router
The Cisco 3250 Mobile Access Router hardware is configurable through stackable interface cards, including:
• Cisco 3251 Mobile Access Router Card (MARC)—The routing engine of the router that includes the host
processor and memory as well as one auxiliary/asynchronous port, one Fast Ethernet port, and one console port
• Cisco 3201 Serial Mobile Access Router Interface Cards (SMICs)—Provide four asynchronous and synchronous
serial interfaces on the router that connect to wired and wireless LAN and WAN communication devices
• Cisco 3201 Fast Ethernet Switch Mobile Access Router Interface Card (FESMIC) —A 4-port, 10/100 autosensing
Ethernet switch that supports 802.1q and 802.1p standards
The Cisco 3250 Mobile Access Router system comprises one MARC and various combinations of Cisco Mobile
Interface Cards (MICs). This allows flexible configurations optimized for a wide range of applications and solutions.
It also allows configuration changes to incorporate future applications and future wired or wireless technologies.
Cisco 3220 Mobile Access Router
The Cisco 3220 is a preconfigured model of the Cisco 3200 Series. It comprises a MARC with one auxiliary/
asynchronous port, one Fast Ethernet port, and one console port, a 2-port SMIC, and a 2-port FESMIC.
The SMIC and FESMIC take advantage of external wireless communication devices such as the Cisco Aironet 802.11
product family and satellite or radio devices. This flexibility allows it to interoperate with most available wireless
networks, both traditional wireless services and emerging wireless technologies.
Software Overview
The Cisco 3200 Mobile Access Router uses Cisco IOS Software. This enables organizations to take advantage of the
proven power, flexibility, and reliability of Cisco IOS Software for their mobile networks. IT managers can, therefore,
take advantage of their investment and training in Cisco IOS Software for their mobile networks.
