CSPFA Remote Lab Instructor Guide 2.0
The remote lab is accessed via a PIX firewall, RL-PIX-CSPFA, from the Internet. The trainer will initiate an IPsec VPN tunnel terminating on RL-PIX-CSPFA. RLPIX- CSPFA forwards all traffic to a router, RL-RMT-CSPFA, which routes traffic based on the source IP address to one of three routers, RL-RMT1-CSPFA, RLRMT2- CSPFA, or RL-RTS-CSPFA. These routers will perform IP address NATing and route the traffic to the necessary student pod.

How to use the attrition program template
The purpose of the template is to differentiate a core group of employees who have excelled in past performance and who show signs of probable future excellence. This template is in an easy-to-use format that can be used for summarizing views on a particular employee’s 2 Ps (performance and potential). This template should be used by any manager in the middle or senior management group who has worked with the employee to be assessed for at least 12 months. Managers should use this to assess any employee who has completed at least 18 months of work experience. How to fill in the template: • The employee's Period...

The Differentiated Services Model
The Challenge: Organizations delivering network-based services need powerful end-to-end solutions to effectively and predictably deliver the differing Quality-of-Service (QoS) requirements of voice, video, and data applications. Voice, for example, requires a small but assured amount of bandwidth, low delay, low jitter and low packet loss. A data application such as file transfer protocol (ftp) needs more bandwidth, but can tolerate the delay & jitter.

LoopStar® 800/1600 SONET Access System DS3 Transmux Card Provides DACS Functionality
As bandwidth needs have increased, enterprise customers have found it more economical to aggregate traffic from remote offices and have it backhauled to the data center via a DS3. For the carrier, this presents a problem. The carrier must be able to access the DS1s within the DS3 and then cross-connect them to the appropriate VT1.5s within the SONET payload. Traditionally, this operation has been performed using a Digital Cross-Connect System (DCS) and a SONET ADM. Obviously, requiring two separate devices for this function increases CAPEX and OPEX for the carrier. With the LoopStar 800/1600 SONET Access System’s DS3 Transmux card, there is now a simpler, more...

Outside Plant Practices Considerations for Saving FTTP Operational Costs
Today’s service providers are under tremendous pressure to ensure their networks are profitable. When it comes to fiber-to-the premise (FTTP) architectures, ADC has done its homework. ADC has helped providers maximize profits while minimizing expenses, and offers several white papers which explain considerations and techniques that can be applied to particular sections of the FTTP network to increase performance, flexibility, and profitability by decreasing capital expenses (CAPEX) and operating expenses (OPEX). Having addressed issues such as cable management techniques, central office considerations and the effects of temperature, this paper will move to the outside plant (OSP) area. It will discuss key practices and options for saving additional OPEX over the...

ADC FIBER SOLUTIONS
CONTROLLING COSTS The cost of the physical network is small compared to the ongoing, laborintensive outlay for installation, expansion, maintenance, and repair. A shortsighted purchase can start a never-ending cycle of expensive support. Worse still is the likelihood of premature obsolescence, which can turn yesterday's bargain into tomorrow's financial disaster.

Operating Fiber Loop Converters Over Multimode Fiber
Fiber Loop Converters are sometimes required to operate over multimode fiber because an existing span of installed multimode fiber may already be in place between two points requiring FLC transmission. The FLCs were designed for use over singlemode fiber, and if there is a choice, singlemode fiber should be installed. However, FLC operation over multimode fiber is possible and, in fact, is a functioning application with several customers. LAN applications over short distances have been successful. The following aspects of this application require attention....
