Cisco network module

Types of cisco network module

Cisco network modules comprise different types of modules that can be plugged into Cisco routers and switches to provide additional network connectivity and functionality. They are used to enhance the network's modular design. Cisco Network modules are designed to deliver high-performance services and can be customized according to varied preferences and requirements.

To fully understand the different types of Cisco network modules, it is essential to know the various terms associated with them. These terms include:

• Interface module (IM): This is usually referred to as a network module when integrated into a Cisco device. It provides additional RJ-45 connectivity.
• Networking services module (NSM): This houses the service blades for services such as voice, VPN, and security. It integrates both hardware and software to carry out multiple network functions.
• Enhanced network services module (ENSM): This provides additional services similar to that of NSM, but is designed for different routers.
• WIC (Wide Interface Card): These are smaller network interface cards that can be installed in routers to enable connectivity to a wide area network.
• HWIC (High-Wide Interface Card): These are also interface cards, but they can be used with newer routers.
• Voice/WAN interface card (VWIC): This can be installed in Cisco routers to connect wide area networks and voice gateways.

The Cisco network module types include the following:

• 1. Cisco PVDM: This module is used to process voice codecs' processing, echo cancellation, and digital signal processing functions.
• 2. SFP Transceiver: The term SFP stands for small factor pluggable. They are compact, hot pluggable, and allow flexible and configurable connectivity solutions for network modules. They support multiple cable types for long-range and short-range connectivity solutions. These modules facilitate connectivity between switches and routers in a telecom, data center, or storage area.
• 3. AXL Tape: A network module that enables the integration of Cisco AXL applications using voice and unified communications. It provides voice applications with a standard web services interface for accessing and managing Cisco call control data.
• 4. ADSL tape: This refers to Asymmetric Digital Subscriber Line, a tape or module that can be inserted into a Cisco router or network device to provide broadband connectivity over existing telephone lines. ADSL tapes allow businesses to connect to the internet using widely available telephone infrastructure. They provide faster download speeds, which can be used for internet access, VPN connectivity, and remote access.

  The industry collaboration further strengthens these network modules to support secure and interoperable communications and provide a foundation for next-generation collaboration and the Internet of Things (IoT). Cisco contributions to industry standards play a role in shaping the future of secured networks and collaboration technologies.

• Modular Design

  Cisco has equipped its network modules with a modular design to finally customize the modules to fit specific needs. The design simplifies upgrades to Cisco hardware or network architecture as business needs change or technology advances. The modules improve deployment flexibility and streamline technology evolution.

• Integrations

  The integrations empower organizations to extend their network capabilities, improve collaboration, and deliver secure, high-quality experiences across users, applications, and devices. Cisco Edge Network includes integrated wired and wireless access, anc delivery of secure, high-performance application services to users and connected devices.

• Quality at Qualified Eventide

  The Q and QoS qualified events indust EN standard ensures that Cisco modules meet rigorous quality and performance standards for communications and other audio applications. By adhering to such standards, Cisco modules ensure high quality and reliability in various networked applications, including communications, conferencing, and multimedia.

• Cloud Acceleration

  The network module plays a crucial role in accelerating cloud services by optimizing application performance and enabling secure connectivity. Cisco Cloud services network modules empower organizations to easily deliver cloud services and applications with optimal performance, security, and reliability, thus enhancing user experiences and driving business transformations.

• Extended Services Platforms

  Cisco's network module provides an extended services platform consisting of integrated services modules and converged branch infrastructure. This enables enterprises to extend services to any employee, branch, or workspace, enhancing collaboration and delivering network services with consistent security and quality.

Applications of Cisco Network Module

Apart from the core functions of the Cisco network module, there are several instances where it is useful in optimizing network performance, simplifying network management, strengthening network security, and improving productivity.

• Internet connectivity: The primary function of the Cisco network module is to connect the router to the WAN (the internet). If there weren't instances of modules to provide this kind of connectivity, businesses would not be able to connect to the internet, thus limiting their operations.
• Network integration: Because the modules enable various types of network access (LAN, WAN, and internet), they help integrate different networks, forming a unified network infrastructure that can be managed from a central point. This simplifies network management and increases productivity.
• Redundancy: Some modules provide backup internet and network connectivity (redundant links). This ensures business operations can continue even when there is a network failure.
• Improving performance: The Cisco network module can offload various functions from the router so that it can concentrate on routing data and packets through the module for tasks such as network security, convergence, and management. This helps improve overall network performance.
• Multicasting: Some modules enable support for multicasting, which is essential for various applications and services, including streaming media and video conferences.
• VoIP and video collaboration: Cisco network modules are integrated with services for VoIP and video. This allows for the convergence of voice, video, and data on a single platform. The collaboration tools are optimized for various endpoints and offer features such as presence, messaging, and conferencing.
• Content filtering, SSL decryption and entertainment, and security applications: Network modules from Cisco can help secure the network by filtering dangerous or unwanted content. They can also decrypt SSL, which can be crucial for detecting and blocking cyber threats.
• Real-time visibility: Cisco's network modules give network administrators tools for managing the network and monitoring it. They provide real-time visibility into the flow of networks, which helps optimize performance and troubleshoot problems.

How to choose cisco network module

Users need to evaluate their network requirements before selecting any Cisco network module that can meet the demand. Network modules are customizable to support various interfaces. Therefore, when choosing one, consider the number of ports. Also, ensure the selected module is compatible with the existing or intended hardware infrastructure. This network can include routers and switches.

Once the right network module has been obtained, the next important step is to configure it properly to ensure optimal performance and functionality. This can only be successful if the user has the right skill set. Make sure to determine and select the right Cisco network module and its integration by understanding the communication standards and protocols relevant to the business environment.

If unsure, it is possible to request help from the Cisco community or even the vendor to clarify and assist in making the right choice. After obtaining the network module, examine and ensure the vendor provides support and software update policies.

To enhance the overall system, make sure to evaluate the other complementary components, accessories, and equipment that the modules need to work with. This will include cabling and amplifying devices. In case, the selected module is pre-owned, make sure it is registered and in working condition before purchasing. Make sure to compare prices between different vendors in case of an urgent module and see if any customer support policies are provided before and after the sale.
