the types of communications routes that can be created with ECS.
Subsequent chapters in this manual describe these topics in detail.
Groups—Party Line and Fixed
Group communication may be configured in several ways. In a “fixed
group” configuration an operator speaks to all members of the group at
once. However, if a group member responds by calling the operator
back with their answer-back key the audio path goes to operator panel
only.
Alternatively, all members of a group can speak with all other members
of the group at the same time. This is commonly called a “conference”
or “party line”. It is similar to a telephone conference call with its
two-way, full-duplex communication. Members of a party line can join
and leave in real time, making the membership dynamic in the sense
that it is always changing.
Controls—DTMF Sequences, Relays, Routes
An intercom panel can be used to perform a variety of other functions
besides sending audio. It can activate a DTMF sequence to call out on
a telephone line, activate an electronic relay to turn on a light or lock a
door, or activate audio from an external router like a mixer desk. These
types of function are called “controls”.
Call Signals
A “call signal” is an audible or visual signal or ”Tally” sent on an
intercom channel, with or without accompanying audio. These signals
have a variety of purposes from alerting an operator who has taken off
their headset, to activating control sequences.
