Chapter 3 T1 and E1 Dial Feature Cards

Online Installation and Removal of the T1 or E1 DFC

Online Installation and Removal of the T1 or E1 DFC

Overview

To remove a DFC without dropping any calls or connections, you will need to take the DFC out of service by using the busyout command to disable the DFC. The busyout command is executed on a per DFC basis and will gracefully disable the card by waiting for the active services to terminate.

If you have active calls on the DFC after executing the busyout command, wait for the calls to drop. Use the show busyout command to view the status of the termination process.

Caution The online installation and removal (OIR) of new cards should be done ONLY during times of low CPU utilization, such as during maintenance.

Caution To avoid erroneous failure messages, remove or insert only one DFC at a time.

When you replace a DFC with a new DFC of the same type in the same slot, the system software will recognize the new trunk interfaces and bring them up automatically.

If you replace the existing DFC with a new DFC of a different type, you will have to reconfigure the system. For configuration details, refer to the Cisco AS5350 and Cisco AS5400 Universal Gateway Software Configuration Guide.

Removing the T1 or E1 DFC

To remove the T1 or E1 DFC, follow these steps:

Note Following these steps are examples of the output from each command.

Step 1 Determine which slot the DFC is in by entering the show chassis command in privileged EXEC mode:

AS5350, AS5400 specifications

Cisco Systems has long been a leader in the networking and telecommunications field, and its AS5800 series of routers exemplify this tradition. The AS5800, along with the AS5850, AS5350, AS5400, and AS5300, provides robust solutions for service providers and enterprise-level networking applications. Each of these models has distinct features and characteristics that cater to the evolving demands of internet traffic and data processing.

The Cisco AS5800 is designed for high-capacity routing and optimized for broadband services. It supports a wide range of services, including voice, data, and video applications, making it a versatile option for service providers looking to deliver integrated solutions. It is equipped with advanced quality of service (QoS) features that ensure bandwidth is allocated effectively, holding strong even under heavy traffic conditions.

In comparison, the AS5850 offers superior processing capabilities and is typically utilized in larger-scale implementations. This model supports high-density interfaces, allowing numerous connections without compromising performance. Its architecture includes enhanced MPLS (Multiprotocol Label Switching) support, enabling more efficient traffic management and better utilization of network resources.

The AS5350 is known for its scalability and energy efficiency, ideal for voice-over-IP (VoIP) and media gateway applications. It supports various telephony features, such as protocol interworking and transcoding, making it a preferred choice for organizations focusing on digital voice technologies. The AS5300, while slightly older, continues to be a valuable asset for less demanding networks, offering reliable performance with VoIP capabilities and basic data applications.

The AS5400 bridges the gap between high-performance routing and operational efficiency. It incorporates Cisco's proprietary technologies to ensure seamless connectivity and robust failover systems. This model is highly regarded for its security features, protecting network integrity and providing peace of mind for businesses relying on sensitive data transfer.

Overall, Cisco’s AS5800 series showcases a progressive evolution of routing capabilities with enhanced features tailored for resilience, scalability, and performance. These routers not only address the technical needs of modern networks but also strategically position organizations for future growth in an increasingly digital world. Each model, with its unique attributes, continues to support the varied demands of global communication infrastructures.
