Chapter 6 Cabling the Line Ports and Completing the Installation

Connecting the Line Ports to the Network

The First Step-Ordering the EC Ports

This section explains how to order the EC ports and assign them to links. This example is the basis for all following examples.

1.Sort the EC ports in an ascending order by their physical interface numbers. Take the following EC interfaces as an example:

EC1 (subscriber side): 0/1, 0/2, 1/3, 1/5

EC2 (network side): 2/2, 3/1, 3/2, 3/4

2.Order the ports in subscriber/network pairs according to their order in the ECs (the first port in EC1 (subscriber side) is paired with the first port in EC2 (network side) and so on):

Link 1. S=0/1, N=2/2

Link 2. S=0/2, N=3/1

Link 3. S=1/3, N=3/2

Link 4. S=1/5, N=3/4

Single Router MGSCP Connectivity

Four links would require two Cisco SCE8000 platforms. Connect the ordered pairs, each pair of EC ports to a pair of Subscriber/Network ports in a Cisco SCE8000 platform:

Cisco SCE8000 #1: Links 1 and 2

Cisco SCE8000 #2: Links 3 and 4

The actual connections might look like this:

S=0/1, Cisco SCE8000 #1 3/0/0

N=2/2, Cisco SCE8000 #1 3/1/0

S=0/2, Cisco SCE8000 #1 3/2/0

N=3/1, Cisco SCE8000 #1 3/3/0

S=1/3, Cisco SCE8000 #2 3/0/0

N=3/2, Cisco SCE8000 #2 3/1/0

S=1/5, Cisco SCE8000 #2 3/2/0

N=3/4, Cisco SCE8000 #2 3/3/0

Single Router with N+1 Redundancy MGSCP Connectivity

In order to have N+1 redundancy, we must add one extra SCE platform as the standby platform. We also must add two more ports on each EC to be used as standby ports. In this case, we would use three SCE platforms, two on the traffic links and one for redundancy, which would be connected to the standby ports.

If we added ports 0/3 and 2/3 on EC1 and 2/4 and 4/4 on EC2, the ECs would look like this:

EC1: 0/1, 0/2, 0/3, 1/3, 1/5, 2/3

EC2: 2/2, 2/4, 3/1, 3/2, 3/4, 4/4

The standby ports must be the two highest-numbered ports:

EC1 standby ports: 1/5, 2/3

EC2 standby ports: 3/4, 4/4

The traffic ports would be assigned to the links as follows:

SCE8000 specifications

Cisco Systems SCE8000 is an advanced service control edge solution designed to enhance the management and performance of service provider networks. Targeted at carriers and large enterprises, the SCE8000 is characterized by its capacity to efficiently handle traffic management, quality of service (QoS), and policy enforcement across various services including voice, video, and data.

One of the main features of the SCE8000 is its scalability. The platform supports a high-density architecture, allowing service providers to seamlessly expand their networks to accommodate growing traffic demands. This scalability is complemented by an impressive throughput, which enables the handling of millions of concurrent sessions, making it ideal for environments with significant user activity.

The SCE8000 employs advanced traffic management capabilities, leveraging deep packet inspection (DPI) technology. This allows for granular visibility into network traffic, enabling service providers to make informed decisions about resource allocation and policy application. Additionally, the device supports multiple protocol analysis, ensuring compatibility across various network services and enhancing overall efficiency.

Quality of Service (QoS) is another critical characteristic of the SCE8000. The platform provides sophisticated mechanisms to prioritize traffic, thereby ensuring that delay-sensitive applications such as VoIP and video streaming receive the necessary bandwidth. This capability is enhanced by Cisco's intelligent traffic shaping and congestion management features, which work together to optimize the user experience even in congested network conditions.

The SCE8000 also integrates robust security features, including session initiation protocol (SIP) security, to protect against malicious attacks and maintain service integrity. This is particularly important in today's cyber landscape where service providers must safeguard their infrastructure from various threats.

Automation and programmability are essential characteristics of the SCE8000, enabling operators to implement policies quickly and efficiently. This feature allows for dynamic scaling and rapid deployment of new services, significantly reducing the time to market for new offerings.

In conclusion, Cisco Systems SCE8000 stands out as a powerful platform for managing service provider networks. With its high scalability, advanced traffic management, quality of service assurance, robust security features, and automation capabilities, the SCE8000 enables service providers to deliver a superior customer experience while optimizing their operational efficiency. This makes it an invaluable asset for any organization looking to enhance its network performance and service delivery.
