We are giving specifications below, why one should consider procuring Cisco ATM Network Module Networking features, a general overview, description, performance specification, relevant images, a competitive price infographic, and technical information about the NM-1A-T3 model with compatibility.

Bandwidth and Latency of ATM Network Module

Bandwidth refers to the amount of data that can be transmitted over a network at a given time. The NM-1A-T3 Cisco 3600 Series 1-Port DS3 Network Module has a bandwidth of 44.736 Mbps, which is the standard speed for a DS3 connection. This means that the module can transmit 44.736 million bits of data per second.

Latency, on the other hand, refers to the time it takes for a packet of data to travel from one point to another in a network. The latency of the NM-1A-T3 Cisco 3600 Series 1-Port DS3 Network Module is dependent on many factors such as network congestion, routing, and other network conditions. However, in general, latency for a DS3 connection is low, and the module is designed to provide a fast and reliable network connection.

Network Design Considerations

The NM-1A-T3 network module is a high-speed interface module for the Cisco 3600 series routers. It provides one DS3 port for connecting to T3 networks. When designing a network that uses this module, the following considerations should be taken into account:

  • Compatibility: The NM-1A-T3 module is only compatible with the Cisco 3600 series routers. It is not compatible with other routers or switches.
  • Capacity: The DS3 port on the NM-1A-T3 module provides 45 Mbps of bandwidth. It is important to ensure that the network design can support this level of bandwidth and that the routers and switches in the network have the necessary capacity to handle the data transmission.
  • Network Topology: The NM-1A-T3 module is best suited for point-to-point or multipoint configurations. The module can be used to connect to a T3 service provider or to connect to a T3-enabled device. It is not recommended for use in a mesh network.
  • Physical Connectivity: The NM-1A-T3 module requires a physical connection to the T3 network through a 75-ohm coaxial cable. The cable should be properly terminated and grounded to ensure proper signal transmission.
  • Power Requirements: The NM-1A-T3 module is powered by the router and does not require an external power source. It is important to ensure that the router has sufficient power to support the module and that the power supplies are properly configured.
  • Network Management: The NM-1A-T3 module is managed through the router's IOS software. It is important to ensure that the IOS version on the router is compatible with the module and that the network management tools are properly configured to manage the module.

By taking these considerations into account, network designers can ensure that the NM-1A-T3 module is properly integrated into the network and that it provides reliable and high-speed connectivity to T3 networks.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Network Module

The network interface module integrates state-of-the-art designs with different hardware and software components for a completely flexible subsystem. The modules can work on several interfaces, and they are compatible with a wide range of networking devices. They provide services for the processing of events and access from related devices.

The network module can also run on central servers, depending on the network availability and resilience. Users can also distribute most of the module options to different sites for extra system resilience.

They help connect and transfer data between networking devices and the central server or controller. An ethernet cable and IP/TCP are employed for effective connection.

They deliver a great level of flexibility of deployment in data centers, branch offices, service providers, and more. Their integration into different switch and router families is seamless while offering quality and cost-effective solutions.

The network module options include tools that help manage and provide network nodes. The tools also assist in designing policies for applications. Users can configure the application policies in various sequences as needed. Software development kits and API are also available to enable flexibility of extension to custom environments.

A wide range of network interface modules is available for use. These include the management modules, which helps to control and monitor network communications. This range of products also provides users with more comprehensive remote monitoring and efficient configuration functions for real-time management.

The voice WAN Card is a flexible solution that supports multiple voices and data applications. This facilitates the movement of channeled voice and data for simplified deployment, sparing, and management.

The fabric module delivers value and offers support for advanced network connection. It enables enhanced network services without compromising performance. There are durable options that deliver outstanding bandwidth as well as improved performance and advanced services. These options are available in a wide range of port options ranging from 1 port to 20 ports and more.

Another reliable network module is the firewall. The firewall helps users filter the traffic that enters and leaves their private networks. Thus, there's adequate protection from viruses, hackers, and other threats. Firewalls are easy to use, often coming with only two options to allow or disallow network access. Therefore, users can be sure of the security of sensitive operational data.

Other network accessories ensure fast and effective transmission of data over the network. Some options transmit up to 40 Gigabit of data per second. Many options also work with a 10-100-1000 Mbps network for versatile business and personal use. These are robust, durable, and efficient network interface module options that users can only get at AllHDD.

Network Module Key Features

  • Controls the controllers at a single network site or across multiple network sites
  • Retains a subset of databases that are relevant to the network site being controlled
  • Communicates with the central server to discover and correct networking issues
