Chapter 2 Dial Feature Card and Carrier Card Guidelines

Online Insertion and Removal (OIR) of DFCs

•Universal access (analog modem or digital calls) is supported when an interface is configured for ISDN PRI signaling. PRI signaling is available for both T1 and E1 trunks.

In any single DFC slot, you can install your choice of:

•One T1, E1, or T3 dial feature card

•One universal port card

Online Insertion and Removal (OIR) of DFCs

All DFCs on the Cisco AS5350 and Cisco AS5400 chassis support online insertion and removal (also known as hot swapping). You can install, remove, replace, and rearrange the DFCs without turning off the chassis power.

When the chassis detects that a DFC is installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the DFC, and resumes chassis operation without any operator intervention.

See:

•Chapter 3, “T1 and E1 Dial Feature Cards,” to perform OIR of the T1 or E1 DFC.

•Chapter 4, “T3 Dial Feature Card,” to perform OIR of the T3 DFC.

•Chapter 5, “Universal Port Dial Feature Card,” to perform OIR of the universal port DFC.

Removing and Installing Populated Carrier Cards

Caution The carrier cards that carry the DFCs are not hot swappable. Removing a card while the system is still powered on may cause permanent damage to electronic circuits on the card.

The DFC carrier card plugs into one of the backplane slots and supports two DFCs. The carrier card increases backplane capacity and allows OIR of the DFCs. (See Figure 2-1.)

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.
