Configuration Tasks

same operations; the QoS tasks they perform might also differ. To configure your IP network for real-time voice traffic, you need to consider the functions of both edge and backbone routers in your network, then select the appropriate QoS tool or tools.

In general, edge routers perform the following QoS functions:

•

•

•

•

Packet classification

Admission control

Bandwidth management

Queuing

In general, backbone routers perform the following QoS functions:

•

•

•

High-speed switching and transport

Congestion management

Queue management

Scalable QoS solutions require cooperative edge and backbone functions.

Configuring Custom Queuing and IP RTP Reserve

Although not required, you can use the custom queuing QoS tool to fine-tune your network for real-time voice traffic. Real-time voice traffic is carried on UDP ports ranging from 16384 to 32767. Custom Queuing and other methods for identifying high priority streams should be configured for these port ranges. For more information about custom queuing, refer to the “Congestion Management” chapter in the Cisco IOS Release 12.0 Quality of Service Configuration Guide. For more information about configuring IP RTP Priority, refer to the Cisco IOS Release 12.0(5)T IP RTP Priority feature module.

Configuring Voice Ports

When an ISDN interface on the Cisco AS5800 is carrying voice data, it is referred to as a voice port.

Note A voice port was created automatically when you installed the VFC in the Cisco AS5800 and configured an ISDN PRI group. Configuring an ISDN PRI group is part of the basic Cisco AS5800 configuration procedure. For more information, refer to the Cisco AS5800 Universal Access Server Software Installation Configuration Guide.

Signaling in Voice over IP for the AS5800 is handled by ISDN PRI group configuration. After ISDN PRI is configured for both B and D channels for both ISDN PRI lines, you need to issue the isdn incoming-voicecommand on the serial interface (acting as the D channel) to ensure a dial tone.

Under most circumstances, the default voice-port command values are adequate to configure voice ports to transport voice data over your existing IP network. Because of the inherent complexities involved with PBX networks, you might need specific voice-port values configured, depending on the specifications of the devices in your telephony network. For more information on specific voice-port configuration commands, refer to either the Cisco IOS Release 12.0(3)T Voice over IP for the Cisco AS5300 feature module or the Cisco IOS Release 12.0 Voice, Video, and Home Applications Command Reference.

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.
