Serial Mobile Interface Card

The Serial Mobile Interface Card is one component of the Cisco 3200 Series Mobile Access Router. It provides the router up to 4 high–speed sets of serial signals in both data terminal equipment (DTE) and data circuit equipment (DCE) modes. Additional components provide power and link interfaces to the SMIC. For example, the Cisco 3270 Rugged Router card provides the host processor, memory, and headers for the Fast Ethernet, console, and auxiliary signals for the router. The exact configuration of your router will vary, depending on how it was configured by your vendor.

Note This section provides basic information about the SMIC hardware for the purpose of performing simple troubleshooting, such as reconnecting a loose cable. To solve more difficult problems, please contact your vendor.

Each SMIC provides the following:

Support for two to four sets of serial signals with protocol support for High-Level Data Link Control (HDLC), asynchronous, synchronous and octet-oriented PPP modes. The signals can be configured to any serial standard (EIA/TIA-232, EIA/TIA-449, EIA/TIA-530, EIA/TIA-530A, EIA/TIA-X.21, or CCITT V.35).

DCE and DTE mode support on each set of serial signals.

Speeds of 2 Mbps for synchronous data transfer and 115 kbps for asynchronous data transfer on each serial interface. All serial standards reach 2 Mbps (for synchronous) except for the EIA/TIA-232 standard, which supports up to 192K.

Note The Peripheral Component Interconnect (PCI) bus and the Industry Standard Architecture (ISA) bus use keying features in the standard stacking headers to guarantee proper module installation. On the PCI bus, pin D30 is removed and its opening is plugged. On the ISA Bus, pin C19 and pin B10 are removed, and their openings are plugged.

The PCI bus connector supports communication between the SMIC, the Fast Ethernet Switch Mobile Interface Card (FESMIC), and the Cisco 3270 Rugged Router card or Mobile Access Router Card (MARC). The Wireless Mobile Interface Card (WMIC) communicates with the router through an internal Fast Ethernet port and is configured through an independent console port; the WMIC only draws power only from the bus.

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.
