10 DL-WINDOWS™ for Trilogy Networx™ V4.0 USER'S GUIDE

Terminology

access to the virtual locks by the various Users in the Ac-

count.

Real - Same as "Physical". Tangible, not virtual. See Virtual.

Subnet (SUBNETwork) - To improve security and processing

performance, network administrators often divide their

corporate Intranets into interconnected but separate seg-

ments called "subnets". Subnets also allow multiple us-

ers to access the Intranet with the same subnet address.

A router is typically used to allow network traffic to pass

between subnets.

Subnet Mask - The IP protocol makes use of a Subnet

Mask to more efficiently route packets to their correct

network destinations. When a Gateway receives a data

packet, the Subnet Mask indicates how many bits of the

packet's destination address are to be used for routing

and which bits are to be "masked" (ignored). The Sub-

net Mask can be thought of as a "filter" that allows the

system to ignore unnecessary information, thus increas-

ing efficiency. This information must be obtained from

your network administrator.

Upload - See Communicate.

Virtual - Simulated on a computer. DL-Windows allows you to

create a lock "Profile" that can be thought of as a "virtual"

lock, created within DL-Windows, that contains all of the

data that a "real" (physical) lock uses to perform its various

functions. When creating these "virtual" lock Profiles, you

are also designing the entire "virtual" system--

conceptualizing which doors will have which locks, adding

User Names and allowing or restricting access to the virtual

locks by the various Users in the Account. Later, you will

"Link" these lock Profiles with the real locks installed on the

doors.
