Appendix A The External Optical Bypass Module

Installing the External Bypass Module

The following figure illustrates the connectivity of the External Optical Bypass module.

To cable the External Optical Bypass module:

Step 1 Connect an optical cable (user supplied) between the GBE port on the Subscriber side network element and the SUB port on the External Optical Bypass module.

Step 2 Connect an optical cable (user supplied) between the GBE port on the Network side network element and the NET port on the External Optical Bypass module.

Verify that the links between the two network elements are active.

Step 3 Connect the SUB cable of the fiber of the External Optical Bypass module to the SUB GBE port of the SCE 2000 platform.

Rx <-> Tx

Step 4 Connect the NET cable of the fiber of the External Optical Bypass module to the NET GBE port of the SCE 2000 platform.

Rx <-> Tx

Step 5 Power up the SCE 2000 platform, as explained in Starting the System and Observing Initial Conditions (on page 7-2).

Warning Auto-Negotiation should be configured identically for the two SCE 2000 platform GBE interfaces and the GBE interfaces of the switch/router on either side of the External Optical Bypass module.

It is recommended that the two GBE interfaces of the SCE 2000 platform, as well as the GBE interfaces of the switch/router on either side of the External Optical Bypass module, be configured to Auto-

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.
