Field Tech 6 Questions and Answers 2023

Field Tech 6 Questions and Answers 2023 Which piece of equipment in the VoIP phone system routes a call to the public switched telephone network (PTSN) when the receiving location is from outside the PacketCable 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 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 VoIP service tiers bypass the cable operator's direct link to the public switched telephone network (PSTN) and route 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. What organization is responsible for developing telecommunication standards that address commercial building cabling for telecom products and services? Telephone Industry Association / Electronic Industry Association (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? Building entrance. When a circuit is cross-connected to a customer's 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 Ordering Code (USOC) RJ-XX wiring. Which pins are often not installed in a 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 Ordering Code (USOC). Which tool is used to force down a twisted pair conductor in an insulation displacement connector (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 because of flame rating and manufacturer. The IDEAL Pathfinder Tester is made up of: One main unit and up to four remote modules. One of the functions of the IW (inside wire) cable tester is to: Test line cords that connect the customer premises equipment (CPE) to modular data and telephone jacks. When using a twisted-pair cable tester, a green condition means: Continuity exists throughout the circuit pair without faults. A wire map field cable tester can include a time domain reflectometer (TDR) to determine the distance to any breaks, shorts, or missed wires. In what situations can the tester be used? It is used to certify structured wiring in commercial buildings and can be used to verify inside wire (IW) in residential settings. Which of the following best describes how a wiremap tester checks pin-to-pin continuity? A wiremap includes one unit that injects a signal at one end of the cable and a second unit that checks the signal at the other end. What causes unshielded twisted-pair (UTP) cable to come in a variety of thicknesses? UTP jacket thickness varies because of flame rating and manufacturer. The terminator tool is used to: Give new service or take away service to a customer. Which tool is used to tighten "F" connectors securely? 7/16 inch wrench Which of the following features are normally part of a PBX system? Call forwarding, call waiting, speed dialing. Which key system architecture enables individual telephone sets that do not require any single shared-control unit? Independent keysets. Which type of telephone system allows a company to have a single phone number reach all employees even though they reside in different geographical locations? Hosted PBX. Which telephone system is characterized by dual tone multi-frequency (DTMF) tones being transmitted to the central office? Traditional. Which phone system generates dial tone at the central office? Traditional. What is the maximum number of hunt groups that can be set up for a business IP voice account? Three. Which of the following is a feature of a PBX? Each phone is addressable.
