We are giving specifications below, why one should consider procuring Cisco Other Expansion Module Networking features, a general overview, description, performance specification, relevant images, a competitive price infographic, and technical information about the HWIC-1T1/E1 model with compatibility.

Introduction to the Module

The HWIC-1T1/E1 is a Cisco high-speed WAN interface card (WIC) expansion module designed to provide additional connectivity options for Cisco routers. Specifically, the HWIC-1T1/E1 provides a single T1 or E1 connection, which can be used for high-speed data transfer, voice, and video applications.

The HWIC-1T1/E1 supports both T1 and E1 interfaces, which are commonly used for connecting to service provider networks, such as T1 lines used for connecting to the Internet, and E1 lines used for connecting to private networks or for voice and video applications.

This expansion module supports up to 2.05 Mbps of data transfer, which is significantly faster than traditional serial interfaces. The HWIC-1T1/E1 is also hot-swappable, which means that it can be inserted or removed from a running router without disrupting network operations.

Installation and Configuration

The HWIC-1T1/E1 is a Cisco High-Speed WAN Interface Card (HWIC) designed for use with Cisco routers. It provides a single T1 or E1 port that can be used for high-speed data transfer over a Wide Area Network (WAN).

Here are the steps to install and configure the HWIC-1T1/E1 module:

  • Shut down the router and disconnect all cables from it.
  • Locate the HWIC slot on the router and remove the slot cover.
  • Insert the HWIC-1T1/E1 module into the slot until it clicks into place.
  • Reconnect all cables to the router.
  • Power on the router and wait for it to boot up.
  • Log in to the router's configuration interface.
  • Enter the configuration mode and configure the HWIC-1T1/E1 module with the appropriate settings.

For example, if you are using a T1 connection, you will need to configure the module for T1 operation by entering the following commands:

interface serial 0/0/0 no shutdown clock source line linecode b8zs channel-group 0 timeslots 1-24

If you are using an E1 connection, you will need to configure the module for E1 operation by entering the following commands:

interface serial 0/0/0 no shutdown clock source line linecode hdb3 channel-group 0 timeslots 1-31

These commands configure the HWIC-1T1/E1 module for operation with the appropriate line coding, clock source, and channel group settings. You may need to modify these settings depending on your specific network configuration.

Once you have configured the module, you should be able to use it for high-speed data transfer over your WAN connection.

Compatibility and Interoperability

The HWIC-1T1/E1 is a high-speed expansion module for Cisco routers and switches that provides connectivity for T1/E1 lines. It allows for a maximum data transfer rate of 2.05 Mbps and is designed to be compatible with a wide range of Cisco products.


The HWIC-1T1/E1 module is compatible with a variety of Cisco router and switch platforms, including the following:

  • Cisco 1800 series routers
  • Cisco 1900 series routers
  • Cisco 2800 series routers
  • Cisco 2900 series routers
  • Cisco 3800 series routers
  • Cisco 3900 series routers
  • Cisco 2900 series switches
  • Cisco 3900 series switches


The HWIC-1T1/E1 module is designed to be interoperable with a variety of other Cisco products and technologies, including the following:

  • Cisco IOS Software: The HWIC-1T1/E1 module is supported by Cisco IOS Software, which is the operating system used by Cisco routers and switches. This ensures that the module can be easily integrated into existing Cisco networks.
  • Voice over IP (VoIP): The HWIC-1T1/E1 module can be used with Cisco's VoIP technologies to provide voice services over T1/E1 lines. This allows for cost-effective and efficient voice communication within an organization.
  • Frame Relay: The HWIC-1T1/E1 module is compatible with Cisco's Frame Relay technology, which allows for the creation of virtual circuits (VCs) over T1/E1 lines. This allows for efficient data transfer between remote locations.
  • Point-to-Point Protocol (PPP): The HWIC-1T1/E1 module supports PPP, which is a protocol used for establishing a direct connection between two nodes over a serial link. This allows for efficient data transfer between remote locations.

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.

For all your expansion module needs, we've got you covered with high-performance devices that increase functional capability and ease business processes.

You can talk to any of our staff and consult on what would be the best way forward when getting an expansion module to complement and enhance existing infrastructure, meet your immediate and future needs.

We have hardware level 12 with firmware 3.0 or higher modules that allow for the installation of up to 14 expansion modules below the base module for resilient performance. Expansion modules connect to the base module using USB Type-A connectors. That's not all, we have hardware level 11 and lower that supports up to 9 expansion modules.

With an expansion module, you get additional cartridge storage as well as tape drive capacity. We have expansion modules that contain up to two drives and two power supplies. You can choose to have the expansion module with tape drives and power supply installed so that it makes setup easier from your end. Expansion modules will need a power supply only if you install a tape drive in it. A single power supply can actually power two drives. However, you can add a second power supply for redundancy purposes. Without a tape drive, the expansion module is powered via the USB cable connected to the base module.

Expansion modules require 2U rack space and will be shipped with the necessary mounting hardware used to secure it to the rack.
