Progression: Field Tech V - VI Conventional

Which concept has enabled Software as a Service (SaaS), Platform as a Service (PaaS), and Networking as a Service (NaaS) offerings? - The separation of the transport and connectivity from the applications and services running atop the transport. Which piece of equipment in a VoIP (voice over Internet protocol) phone system routes a call to the public switched telephone network (PSTN) when the receiving location is from outside the Packet Cable managed IP network? - Gateway What are the three sub-network interfaces managed by PacketCable? - Hybrid fiber/coax (HFC), managed IP, and public switched telephone network (PSTN). Why is PacketCable VoIP (voice over Internet protocol) a more efficient way of handling calls? - Most cable operators have built their own IP telephone networks that use Internet protocol rules. Which of the voice over Internet protocol (VoIP) service tiers bypasses the cable operators direct link to the public switched telephone network (PSTN) and routes packets over the Internet to another telephone company? - Tier II Secondary VoIP. When a call is made from a phone that is on a managed IP phone system to a phone that is outside the managed IP phone system, how does the call get routed to the receiving phone? - The gateway down-converts the digital data to an analog electrical signal format and routes the call to the public switched telephone network (PSTN). Because a cable operator will support as many lines as technically possible for a business customer, what does the installer have to do prior to connecting the embedded multimedia terminal adapter (EMTA)? - Check the RF signal levels on the cable entering the building. When a PBX or key system is involved in a business installation, the installer can set up the embedded multimedia terminal adapters ( EMTA ) and cable, but what has to happen before the installer can begin connecting the equipment? - The customer's PBX and key system technician must arrive at the location. For a business telephone installation, which of the following is the preferred location for the embedded multimedia terminal adapter (EMTA)? - The Main Closet Which of the following is a process that must be followed during a business order installation and differs from a residential order process? - Making sure the PBX is tested and is functioning properly. What is the location where the embedded multimedia terminal adapter (EMTA) is connected to both the outside and inside wiring? - The main closet or telecommunications closet. Before a business telephone installation is performed in an office building, who must first approve it? - The building owner or management company. This organization is responsible for developing the telecommunications standards that address commercial building cabling for telecom products and services with wiring standards such as T568A and T568B to ensure consistent wiring and service delivery. - The Telecommunications Industry Association - TIA When extending wiring into another part of a building becomes necessary, who is responsible for initiating the service? - The customer. Who owns and is responsible for the wiring between the small and medium business (SMB) customer's cross-connect block and the cross-connect block installed by the cable operator? - The customer. What is the advantage of using a multiple-clip configuration for distribution applications in the 66-block? - Several extensions can have a direct (i.e., home-run) connection to the same network circuit. Several extensions can have a direct (i.e., home-run) connection to the same network circuit. - Telecommunications Industry Association/Electronic Industries Alliance - TIA/EIA According to Telecommunications Industry Association/Electronic Industries Alliance - TIA/EIA standards, which type of unshielded twisted-pair (UTP) cabling is recommended for data-grade applications? - Category 5e. Which configuration enables several telephone extensions to have a direct (home- run) connection to the same network circuit? - A multiple-clip configuration. If it is necessary to run cables from one intermediate distribution frame (IDF) to another, what type of connection block is used? - M66-150. Grounding and protection are required in two places. One is in the equipment room or telecommunications closet. Where is the other? - The Building Entrance When a circuit is cross-connected to a customers equipment or telephones, it is tagged for identification. Where else are telephone numbers and line positions on the embedded multimedia terminal adapter (EMTA) noted? - On the orange cover of the 66-block. Why is the T568A wiring configuration recommended over the T568B wiring configuration? - The T568A configuration is backward compatible with Universal Services Order Codes (USOC) RJ-XX wiring. Which pins are often not installed in an RJ-11 jack? - Pins 1 and 6. In a T568A wiring scheme for a four-pair connection, which pair uses white/brown for tip and brown/white for ring? - Pair 4 When installing a 66-block, which mounting guidelines should be followed? - A mount-support bracket ( also called a stand-off bracket ) should be installed to help provide needed clearances. What is a main distribution frame? - A wiring arrangement that connects outside and internal telephone lines. What is the maximum pulling tension for a four-pair unshielded twisted-pair ( UTP ) CAT-5e cable? - 25 lbs When running unshielded twisted-pair (UTP) cable, it is critical that - The minimum bend radius be maintained to no less than 4 times the outside diameter. If a 66-block has a green cover, what does that designate? - Network connections. What code covers the installation of station jacks? - Universal Service Order Codes (USOC). Which tool is used to force down a twisted pair conductor in an insulation displacement connection ( IDC ) termination? - Punch Down Tool When stripping unshielded twisted-pair - UTP cable, what is one factor that must be taken into account to ensure proper stripping? - Jacket thickness varies due to flame rating and manufacturer. What tool should be used to test the line cords that connect the customer premises equipment (CPE) to modular data and telephone jacks? - An inside wire cable tester
