Talk level 1 is the normal talk key assignment. This is the assignment that normally appears in the
Talk Level 1
alphanumeric display (on keypanels so equipped). You may add a talk level 2 assignment to
activate a second device along with talk level 1.
Talk level 2 is used with stacked talk keys. A stacked talk key activates two types of
Talk Level 2
communication at once. For example, a stacked talk key could simultaneously activate audio
output to a transmitter and key the transmitter using a relay. The audio output is called the level l
assignment and the relay is called the level 2 assignment.
Trunking is a method of interconnecting two or more independent intercom systems. The
Trunking
connection is accomplished by reserving one or more audio ports in each of the intercom systems
for use as audio links between the systems. A special device, called a Trunking Master Controller,
is required to control access and usage for the trunked intercom ports. A configuration utility,
called CStrunk, is used to set up the Trunking Master Controller.
