Define the following terms: a. CPS-Central Processing System- the â€Å"brains† of the switch. The main functions of the CPS are global call processing, network control, signaling control, maintenance, and administration. It is responsible for system, recovery, software upgrades, storage of global routing information, and distribution of information to all subsystems. b. NCP- Network Control Processor- the mini brains of the switch. It is connected to the CPS and the line and trunk modules. It receives questions from the line and trunk units regarding call routing, feature requests, and so forth. c. ICS- Interface Controller- Interface between the NCP and the line modules. The IC sits between the switching fabric and the line or trunk modules and is used to connect the two. It can be considered the highway that is used to pass messages between the different modules cause it talks to the NCP. d. Trunk Module- The portion of the switch where the trunk circuits terminate. The y terminates trunks into the switch. Trunks arrive from other switches, and terminate at the trunk module. e. Line Module- The portion of the switch where the individual POTS lines terminates. The line module is the module that interfaces with the subscriber’s line. 3. Explain the difference between a tandem switch and a class 5 switch. f. The tandem switches main purpose is to switch trunks, routing them between class 5 switches. Many class 5 switches now have tandem switch capabilities blurring the line between class 4 and 5 switches. 4. Explain the difference between a tandem switch and a long distance switch. g. .. 5. Explain the difference between a long distance switch and an international switch. h. .. 6. Explain how a class 5 switch routes a call traveling between two lines that are served from the same switch. i. .. 7. Explain how a call is routed between an end-office switch and the local tandem switch. j. .. 8. 9. 10. Why do business customers purchase private branch exchanges? k. The private branch exchanges is like the class 5 switch but it resides at the customer’s premises. It routes incoming and outgoing calls, provides features on the line, and keeps call records on each individual line. It reduces the number of lines needed between the business and the telephone company. 11. 12. 13. 14. Define each part of the following number as defined by the North American numbering plan: 818-555-9877. l. 818 is a three-digit area code-Numbering Area Plan (NPA) m. 555 is a three-digit number exchange (NXX) n. 9877 is a four-digit subscriber code (XXXX) 15. 16. 17. 18. 19. 20. Define the following terms: o. usy hour- the number of calls a switch can hold is the busy hour call attempts. This type of blockage happens when the switch’s processing power or CPU is too small to handle the call volumes. p. average hold time- the average time a subscriber remains on the telephone. 21. Name five features offered by the class 5 switch. q. three-way calling r. speed calling s. call waiting t. call forwarding u. voicemail 22. List three of the CLASS features offered by the class 5 switch. v. Automatic recall (redial) w. calling number identification (caller ID) x. distinctive ringing

Technical Report Writing Course Lessons Learned

Technical Report Writing Course Lessons Learned "Risk being unliked. Tell the truth as you understand it. If you’re a writer you have a moral obligation to do this." ~ Anne Lamott After leading technical report writing courseswith large and small companies for nearly 20 years, I have seen a common challenge present repeatedly. Telling the truth can be hard. Conveyingfindings or recommendations that we know aren't welcome can be daunting because no one wants to disappoint people, especially a boss. But, truth in business reports is absolutely essential. There is no way around it. We must be 100% truthful in business reports. If we aren't, the results can be disastrous. A Technical Report Writing Course Story from the Trenches Aplastic-producing company clienttold me they lost their largest customerwhen the polymers the companyproduced broke down ata particular temperature. This shouldn't have happened because extensive testing had been conducted on the polymers, which reportedly had withstood temperatures far in excess of the breakdown point encountered. When we deconstructed the information path backwards from the customer proposal that specified the polymerperformance to production reports to testing reports, we noticed some ambiguity in testing reports. The testing reports didn't overtly state the temperature breakdown point. Instead, it simply stated "acceptable heat tolerance." That vagueness shouldn't have been allowed into production. It did move to production, though,because various readers of the testing reports had different understandingabout the meaning of "acceptable heat tolerance." That was mistake # 1, and was more about accuracy (also critical) than truth.We discovered a bigger truth mistake as we continued to excavate the information path to its source. The person who wrote the testing report confided in me that he felt a lot of pressure to "...approve the testing because we needed to move into production fast to meet order demand. My boss would have been very unhappy with me if I had been the one to identify that this major product really had limited heat application. Our bonuses were tied to our innovation and production." Ugh. A "small" sweep-it-under-the-rug-move-it-along choice eventually cost the company its largest customer and opportunity. The fallout in publicity and liability was far worse than any delay and resolution would have been. The testing engineer rightly lost his job. Nothing good happened by not reporting truthfully. I could tell you story after story I've heard in training sessions and client meetings about the harm of sidestepping difficult issues in reports. Nothing. Let me repeat, nothing, matters more in reports than truth and accuracy. Decisions are made based on reports. If the information is not accurate and truthful, the decisions are based on faulty data or information. hbspt.cta._relativeUrls=true;hbspt.cta.load(41482, '934718b3-251a-45d6-8853-a7f94e43b92c', {}); Don't be Afraid to ConveyBad Newsin Business Reports Never apologize for delivering "bad news" at work in any circumstance. If it's a good business decision, just state the truthful facts. Apologizing just undermines the good decision. Omitting information is more dangerous than truth. Remember, technical business reports and business reports are used for decision making. If the information in the report is not truthful, the report is dangerous to the company's profit and reputation. It can alsocause potentially dangerous implications when implemented. Another client contacted us afterfor technical report writing training whenmetal triggers they manufactured forlaw enforcement weapons failed to work. The cause was the same. A testing engineer was afraid of being blamed for a production delay and disappointing his boss. (He also reported "there was no place in the report template for the information," but that is a separate report writing issue to address in another article.) A police officer was injured when a weapon he needed defensively failed to work. Truth matters in report writing. "Risk being unliked. Tell the truth as you understand it.
