More Information of WAN Interface Card

The HWIC-1DSU-T1= (High-Speed WAN Interface Card - 1 Digital Service Unit - T1) is a type of network interface card (NIC) that can be used to provide a T1 connection on a Cisco router. A T1 connection is a type of digital transmission line that can transmit data at speeds up to 1.544 megabits per second (Mbps). This Item is a single-port card, meaning that it has only one T1 port and can be used to connect a single T1 circuit to the router. It can be used in a variety of applications, such as connecting a local area network (LAN) to a wide area network (WAN), or providing Internet access to a group of users. The Model is designed to be installed in a Cisco router that has an available slot for a WAN interface card.

High-Performance and Throughput

This item is a hardware interface card that provides one port of WAN connectivity using a T1 interface. This card can be installed in a Cisco router to provide a connection to a Wide Area Network (WAN) using a T1 connection.

The T1 interface operates at a speed of 1.544 Mbps, which is a common speed used for WAN connections. This interface supports both full-duplex and half-duplex operation, with the full-duplex mode providing higher performance. The card also supports various framing formats, including D4 and ESF, which can be used depending on the requirements of the WAN connection.

This model card is designed for use in a range of Cisco routers, including the 1800, 2800, and 3800 series. It can be used to provide WAN connectivity for applications such as voice, data, and video.

Network Monitoring and Troubleshooting

The Cisco HWIC-1DSU-T1= Voice WAN Interface Card provides network monitoring and troubleshooting capabilities to help diagnose and resolve network issues. This includes the ability to monitor T1 line status and performance, detect and report line errors, and identify issues with network connectivity. The card also provides tools for troubleshooting, such as alarms and logs, that can be used to isolate problems and quickly resolve issues. Additionally, the card supports remote management capabilities, which allow network administrators to monitor and manage the card from a remote location. This makes it easier to identify and resolve issues, even if the card is located in a remote or difficult-to-reach location.
