Module 02 Flashcards
A subgroup of the former EIA that focuses on standards for information technology, wireless, satellite, fiber optics, and telephone equipment. EIA was dissolved in 2011, and its responsibilities were transferred to ECA (Electronic Components, Assemblies, Equipment & Supplies Association).
TIA (Telecommunications Industry Association)
A private, non-profit entity consisting of a membership of standards writers and users. ANSI oversees standards development and provides accreditation for approved standards for a period of five years, at which time the standards must be revised, rescinded, or reaffirmed.
ANSI (American National Standards Institute)
A method for uniform, enterprise-wide, multivendor cabling systems specified by the ANSI/TIA-568 family of standards. Structured cabling is based on a hierarchical design using a high-speed backbone.
Structured cabling
The location where an incoming network service (whether phone, Internet, or long-distance service) enters a building and connects with the building’s backbone cabling.
EF (entrance facility)
The point of division between a telecommunications service carrier’s network and a building’s internal network.
Demarc (demarcation point)
Also known as the main cross connect, the centralized point of interconnection between an organization’s LAN or WAN and a service provider’s network.
MDF (main distribution frame)
A wall- or rack-mounted panel where cables converge in one location. Also called a patch bay.
Patch panel
A wall- or rack-mounted panel where cables converge in one location. Also called a patch panel.
Patch bay
The provision of telephone service over a packet-switched network running the TCP/IP protocol suite.
VoIP (Voice over IP)
A device that converts signals from a campus’s analog phone equipment into IP data that can travel over the Internet, or that converts VoIP data from an internal IP network to travel over a phone company’s analog telephone lines.
Voice gateway
A signaling protocol that is used to make an initial connection between hosts but that does not participate in data transfer during the session. SIP is a common application layer protocol used by voice gateways to initiate and maintain connections.
SIP (Session Initial Protocol)
An end user device or application that gives the user access to VoIP services on a network.
VoIP phones
A pointed tool used to insert twisted-pair wire into receptors in a punchdown block to complete a circuit.
Punchdown tool
A type of punchdown block designed to terminate Cat 5 or better twisted-pair wires and typically used to handle data connections rather than telephone connections. The numeral 110 refers to the model number of the earliest blocks.
100 block
A proprietary type of punchdown block developed and patented in Europe. Like the more common 110 block, it’s typically used to handle data connections rather than telephone connections.
Krone (Krone LSA-PLUS) block
A compact type of punchdown block typically used to handle data connections rather than telephone connections.
BIX (Building Industry Cross-connect) block
A type of punchdown block designed to terminate telephone connections. The numeral 66 refers to the model number of the earliest blocks.
66 block
A junction point between the MDF and concentrations of fewer connections—for example, those that terminate in a data closet.
IDF (intermediate distribution frame)
