Chapter 6 Wireless Mobile Interface Cards

In contrast, the Serial Mobile Interface Card (SMIC) and FESMIC communicate with the router through the PC/104-Plusbus. The interfaces are configured through the router console port, and all of the router and FESMIC Fast Ethernet ports are identified by using the slot/port format.

The WMIC runs an independent Cisco IOS image and when it is configured, the link between the WMIC and the router forms an internal LAN. In standard configurations, a WMIC Fast Ethernet port is never brought out to the end cap.

The WMIC console port is brought out to the corresponding RJ-45 port on the I/O end cap, replacing a Fast Ethernet port. If the router includes one WMIC, the RS-232 WMIC console port replaces a Fast Ethernet port on the end cap. If the router includes two WMICs, two WMIC EIA/TIA-232 console ports replace two Fast Ethernet ports on the end cap.

Note At present, even if the router contains zero WMICs, in standard configurations a maximum of three Fast Ethernet ports are brought out to the end cap. Unused EIA/TIA-232 ports are sealed.

Fast Ethernet Signals on the WMIC

The Fast Ethernet signals are delivered through a 10-pin header. LED signals and EIA/TIA-232 console signals are provided through the 24-pin multifunction header.

There is one set of fixed Fast Ethernet signals on the WMIC. The Fast Ethernet port signals comply with IEEE 802.3. The signals are provided through the Ethernet headers, which support the following:

•Autonegotiation for 10/100BASE-TX connection

•Full-duplex and half-duplex modes

•Low-power sleep mode

•10BASE-T and 100BASE-TX using a single Ethernet connection

•Robust baseline wander correction performance

•Standard carrier signal multiple access collision detect (CSMA/CD) or full-duplex operation

•Integrated LED drivers

Note If Auto-MDIX is disabled, when connecting to Ethernet switches or repeaters, use a straight-through cable. When connecting to compatible workstations, servers, and routers, use a crossover cable. If Auto-MDIX is enabled, you can use either a straight-through cable or a crossover cable to make the connection, as the router automatically changes the signals on the pins to compensate.

3200 specifications

Cisco Systems 3200 Series routers are designed to deliver high-performance, reliable networking solutions for enterprise and service provider environments. They are part of Cisco's extensive portfolio that addresses the challenges of modern networking, particularly in connecting remote offices and branch locations efficiently and securely.

One of the standout features of the Cisco 3200 Series is its scalability. The routers support a variety of modular interfaces, allowing organizations to tailor their network infrastructure according to specific needs. This modularity ensures that as businesses grow and their networking requirements evolve, the Cisco 3200 can adapt without necessitating a complete overhaul of existing hardware.

Security is another critical characteristic of the Cisco 3200 routers. They incorporate robust security features such as integrated firewall capabilities, advanced encryption standards, and Virtual Private Network (VPN) support. This ensures that sensitive data transmitted over the network is protected from potential threats, making them ideal for businesses that prioritize security, especially in regulated industries.

Performance-wise, the Cisco 3200 is equipped with advanced processing capabilities, enabling it to handle high data throughput even in demanding environments. This performance is bolstered by the use of Cisco's proprietary technologies, such as Quality of Service (QoS) and traffic shaping, which allow the prioritization of critical applications to ensure seamless connectivity.

The router series also benefits from Cisco's extensive software ecosystem, which includes Cisco IOS (Internetwork Operating System). IOS provides a familiar interface for network administrators, alongside a wealth of features for configuration and management. Furthermore, the Cisco 3200 Series is designed to integrate with Cisco's Application Policy Infrastructure Controller (APIC) and Software-Defined Networking (SDN) solutions, offering enhanced flexibility in managing network resources.

Connectivity options for the Cisco 3200 Series are extensive, offering support for various WAN technologies, including MPLS, LTE, and broadband internet. This versatility enables organizations to choose the best connectivity solutions according to their geographic and operational requirements.

Finally, the Cisco 3200 Series routers are built with reliability in mind. They are designed for high availability and redundancy, ensuring that network services remain uninterrupted in the event of hardware failures or maintenance activities.

In conclusion, Cisco Systems 3200 routers represent a comprehensive networking solution, combining scalability, security, performance, and reliability, making them a preferred choice for organizations looking to enhance their networking infrastructure in a dynamic digital landscape.
