Split Dial Shelves

The following conditions must be met before the dial shelf interconnect port adapter is enabled:

•The dial shelf interconnect port adapter is correctly connected to the router shelf midplane and receiving power.

•

•

A valid Cisco IOS software image for the adapter has been downloaded successfully.

The system recognizes the adapter.

If any of the above conditions are not met, or initialization fails for other reasons, the enabled LED remains off.

The link LED indicates an active connection to the dial shelf. This LED lights when the dial shelf interconnect port adapter is receiving a carrier signal from the dial shelf.

Software and Hardware Requirements

The dial shelf interconnect port adapter requires that the host Cisco 7206 router shelf is running Cisco IOS Release 11.3(2) AA or later.

Note IOS release 11.3 (5.1) AA or later is required to support two dial shelf interconnect port adapters. Two dial shelf interconnect port adapters are required to support dual dial shelf controllers.

Port adapters are rated by data-carrying capacity as high, medium, or low bandwidth. The host Cisco 7206 router shelf has certain data carrying capacity (or bandwidth) restrictions that affect the number of high bandwidth port adapters you can install. The dial shelf interconnect port adapter is considered to be high bandwidth. Refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines document that shipped with your Cisco 7206 router shelf for more information on port adapter installation restrictions.

Split Dial Shelves

The split dial shelf configuration of the Cisco AS5800 dial platform increases bandwidth by using two Cisco 7206 router shelves to service a single Cisco 5814 dial shelf. The dual router shelves serve as the interfaces between the split Cisco 5814 dial shelf and the external network. This configuration provides the equivalent of two Cisco AS5800s in a single rack. Split dial shelf configuration requires two DSC cards and two Cisco 7206 router shelves (both with dial shelf interconnect port adapters). For more information on hardware and software configuration needed for a split dial shelf configuration, refer to the Cisco AS5800 Universal Access Server Split Dial Shelf Installation and Configuration document or the Cisco AS5800 Universal Access Server Operations, Administration, Maintenance, and Provisioning Guide, available soon.

AS5800 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.
