Cisco 7206 Router Shelf

Network Interfaces

Network interfaces reside on port adapters that provide the connection between the router’s three peripheral component interconnect (PCI) buses and external networks. The Cisco 7206 has six slots (slots 1 to 6) for the port adapters, one slot for an Input/Output (I/O) controller, and one slot for a network processing engine (NPE). You can place port adapters in any of the six available slots.

The front of the Cisco 7206 provides access to an I/O controller and up to six network interface port adapters. The I/O controller contains the following:

•Local console port for connecting a data terminal or data terminal equipment (DTE) and an auxiliary port for connecting a modem or other data communications equipment (DCE) or other devices for configuring and managing the router

•Two personal computer memory card international association (PCMCIA) slots for Flash memory cards

•Optional Fast Ethernet port, which provides a 100-Mbps connection to the network

Note The I/O controller is available with or without a Fast Ethernet port. The I/O controller with a Fast Ethernet port is equipped with both a media-independent interface (MII) receptacle and an RJ-45 receptacle; however, only one of these two receptacles can be used at a time.

The port adapters installed in the Cisco 7206 router are of the same type as those installed on the second-generation Versatile Interface Processors (VIP2s) in the Cisco 7500 series routers, in Cisco 7000 series routers using the Cisco 7000 series Route Switch Processor (RSP7000) and Cisco 7000 series Chassis Interface (RSP7000CI), and in the Cisco uBR7246 universal broadband router. The port adapters installed in the Cisco 7206 support OIR. For an explanation of OIR, see the “Online Insertion and Removal” section on page 1-43.

Note The I/O controller does not support OIR. You must power down the Cisco 7206 before removing the I/O controller from either router shelf.

Port adapter slots in the Cisco 7206 routers are numbered from left to right from the bottom up, beginning with port adapter slot 1 and continuing through port adapter slot 6. Port adapter slot 0 is the Fast Ethernet port on the I/O controller. (See Figure 1-20.)

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.
