Cabling Diagrams

Before beginning, find the appropriate cabling diagram for the topology in your installation:

•Single SCE 2000 topologies

•Single Link: Inline Topology (on page 6-2)

•Single Link: Receive-only Topology (on page 6-3)

•Dual Link: Single SCE 2000 Topologies (on page 6-3)

•Dual SCE 2000 topologies (cascaded)

•Dual Link: Two SCE 2000s Topology (on page 6-5)

Note When installing a cascaded system, it is extremely important to follow the sequence of procedures outlined in the section Installing a Cascaded System (on page 6-10).

Single Link: Inline Topology

In the inline topology, the SCE 2000 resides physically on the GBE (Gigabit Ethernet) link between the subscribers, which are usually connected through either a BRAS (in DSL access), a PDSN (in wireless access), a CMTS (in the Cable access), or a switch or router aggregator (in other topologies), and the network, where the SCE 2000 usually connects to a router or layer 3 switch network element.

Figure 6-1: Cabling Diagram for Single Link Inline Topology

In the single link inline topology, either the first GBE link (first two ports) of the SCE 2000 or the second GBE link (third and fourth ports) can be used, as illustrated in the diagram above. The remaining pair of ports is unused.

Either port 1 or port 3 is used for connecting to the network element that is deployed on the subscriber side of the SCE 2000 while port 2 or port 4 is used for connecting to the network element that is deployed on the network side of the SCE 2000.

Inline topology requires both Receive and Transmit fibers

SCE 2000 4xGBE specifications

The Cisco Systems SCE 2000 4xGBE is a robust solution designed to optimize IP networks and enhance service delivery. As a member of Cisco's Service Control Engine (SCE) product line, this device is particularly suited for service providers looking to manage network traffic, improve service quality, and provide a suite of advanced management features.

One of the standout features of the SCE 2000 is its ability to process and analyze network traffic in real-time. This capability allows operators to gain insights into user behavior, application usage, and overall network performance. By utilizing deep packet inspection technology, the SCE 2000 can identify different types of traffic, enabling network managers to enforce policies and prioritize critical applications effectively.

In terms of interface capabilities, the SCE 2000 offers four 1 Gigabit Ethernet (GbE) ports. This versatility allows for easy integration into existing network infrastructure while ensuring ample bandwidth for data transfer. The device supports both IPv4 and IPv6 protocols, making it future-proof and suitable for evolving network demands.

One of the significant technologies employed by the SCE 2000 is Service Level Agreement (SLA) management. This feature ensures that service providers can meet their commitments to customers by monitoring performance metrics such as latency, jitter, and packet loss. The ability to generate reports based on SLA compliance allows for better customer engagement and transparency.

Additionally, the SCE 2000 facilitates dynamic resource allocation, enabling service providers to adapt network resources based on current demand. This elasticity is crucial in managing peak loads and ensuring a seamless user experience. Furthermore, the device’s support for Quality of Service (QoS) policies ensures that critical applications receive the necessary bandwidth and resources dedicated to maintaining operational efficiency.

The SCE 2000 also emphasizes security with features such as intrusion detection and prevention capabilities, helping protect the integrity of the network. This combination of performance monitoring, traffic management, and security makes the SCE 2000 an invaluable tool for service providers.

In conclusion, the Cisco Systems SCE 2000 4xGBE is a powerful network management solution that excels in providing real-time traffic management, SLA compliance, and security features. Its capabilities make it an essential component for service providers aiming to optimize their networks while delivering high-quality services to their customers.
