10 Terminology/glossary
Term Description
4-wire direct
A 4-wire connection is characterized by two pairs of twisted copper
wire which transmit in opposite directions. A 4-wire circuit gives a full-
duplex interface which is often used to connect to third party devices.
When used with the LQ Series, a 4-wire direct connection (as
opposed to a channel) provides point-to-point and panel connections
over IP. The 4-wire direct interface will pass panel data as well as
audio. 2-wire connections are inactive in the 4-wire direct tab of the
Assignments page in the CCM and cannot be used in this context.
CCM
Core Configuration Manager. This is the browser-based
configuration tool that each LQ device is supplied with. It can be
accessed by entering the IP address of your device (shown on the
device front panel) into the address field of a Web browser.
Channel
In the context of the LQ product, a Channel represents a conduit or
holder for routing audio and data (including GPIO triggers) through
your intercom system. As well as routing audio, a Channel also
connects audio and data sources. To use Channels, connect audio to
the port connectors on the device, and assign the port or ports to one
or more Channels. LQ uses two different types of Channel; a regular
Channel and a 4-wire direct Channel. A regular Channel operates
like virtual party or conference line. It comprises audio from multiple
audio interfaces on the devices (ports A-F) that have been assigned
to it. Within a regular Channel, all parties can hear and speak to each
other. A 4-wire direct Channel is made up of only two audio sources
in a one-to-one connection.
Networked Control
Events
Network Control Events are settings on a port that allow GPIO
signals and controls to be passed through your intercom system.
GPIO signals are converted to digital signals and then passed across
the IP infrastructure (as with a 2-wire call signal).There are three
Network Control Events to choose from: 1, 2 and Call.
Host device
The LQ device whose browser-based configuration tool (CCM) your
browser is currently directed to.
Linking The act of joining multiple LQ devices together in one group.
Link-Group A set of devices linked together forming their own isolated network.
