Definition of Terms

The following are definitions of the terms used related to your IHETS Internet connectivity and in the Site Information Survey form emailed to county CEDs. These terms are relevant to your IHETS connectivity.

Demarc Extension

Site Survey term: This is where you want the router to be located physically. If you have a wiring closet then you'll probably want it located there. Otherwise you will likely want the router located close to your current ethernet hub.

 

Director/Manager of Facilities

Site Survey term: Most likely your CED. Someone that could authorize something like wiring modifications etc.

 

Hours of Operation

Site Survey term: When is your office open. If your office ever switches from Eastern Standard Time (EST) you will want to note that too.

 

Hub

A hub is used to connect several computers together. The hub is the place where data comes together and includes a switch which determines how and where data is forwarded from the place where data comes together.

A hub network topology consists of a backbone (main circuit) to which a number of outgoing lines can be attached ("dropped"), each providing one or more connection ports for devices to attach to.

 

Router

A device which forwards packets between networks. The router allows your office computer to connect to the Internet. A router is located at any juncture of networks or gateway and decides which way to send each information packet.

 

Site Physical Address

Site Survey term: Where your office is actually located

 

Technical Site Coordinator

Site Survey term: This is the designated technical person in the CES office. This person will serve as IHETS contact to the office for minor issues. For example, on a rare occasion IHETS may need to ask this person to do something like power-cycle the router.

 

Telco Demarcation

Site Survey term: This is where the phone company's lines enter your building. Typically this would be some sort of punch block and is where the phone line would transition from being the phone company's responsibility to the building's responsibility.

 

UPS

Uninterruptible Power Supply; A battery powered power supply to provide power to a computer in the event of interruptions or spikes in the incoming electrical power. Different rating UPSs will provide power for different lengths of time. UPSs connect to the computer's serial port and use battery power to allow the computer to shut down gracefully before complete loss of power.
