SIP

Session Initiation Protocol. Network protocol for setting up, controlling and terminating a

communication connection via a computer network. SIP is frequently used in conjunction

with IP telephony.

Structured Cabling

Structured cabling is a standardized schematic diagram for the cabling of dierent services

(voice or data). It facilitates the extension of a data network to allow for the subsequent

installation of new components, and therefore supports current and future communication

systems. This is generally based on a validated structure that contains reserves and can

also be used independently of a particular application. Structured cabling must be failsafe

to ensure data protection and data security.

Subnet, Subnet Mask

A subnet is an identiﬁable separate part of an organization’s network. A subnet often

represents all the computers within a geographical location, building or LAN. By dividing

a network into subnets, every subnet can be connected to the Internet using the same

shared network address.

The subnet mask is that part of the IP address that is used by a network router to identify

the subnet to which a data package is to be transferred. The subnet mask saves the router

from having to process the entire 32 bits of the IP address; this way, it can very quickly

process only the bits indicated by the mask.

Switch

Hardware used to connect multiple network devices (computers, cameras, printers, etc.)

within a network. A PoE switch can also supply the (door) cameras with power over an

Ethernet cable. Certain switches also function as routers.

Transponder

A transponder is a device used for wireless communication (for example, as a key fob

or a check card). The device detects the incoming signal and automatically responds

to it or forwards it. The term “transponder” is made up of the terms “transmitter” and

“responder.” Passive transponders do not require their own power source, but they only

work over short distances.

USB (Universal Serial Bus)

Plug-and-Play interface between the computer and peripheral devices (scanners, printers, etc.).

UPS

Uninterruptible Power Supply. Refers to devices that temporarily continue to supply power

in the event of a sudden power failure. These devices usually operate using a battery.

UPS is installed on the power lines of devices and systems in order to protect them in the

event of a power failure.
