7.1 Glossary of Terms
The following is a glossary of terms used in PESA Switching Systems
routing control systems and more specifically, the 3300 Routing Control
System. These are definitions as defined by usage within PESA and may
not reflect the meanings associated with these terms by the video/audio
industry.
All Call
A diagnostic procedure that causes a physical input to be taken to a series
of physical outputs on a specified matrix component.
All List
This list is used in panel configuration and indicates that the panels linked
to this list have access to all the defined items that the list refers to. (e.g.
the ALL source include list indicates that the panel can access all sources
defined in the system.)
Block
A set of contiguous inputs and outputs in each matrix family that are used
for confidence checking. The controller assumes that is any crosspoint
within the block is non-functioning, then all crosspoints in the block are
non-functioning. The block size for System 5 matrices (RM5000, RM4000,
Lynx) is 8 inputs by 2 outputs. The block size for PRC based matrices
(Cougar, Jaguar) is 16 inputs by 16 outputs.
Breakaway Switch
A switch specified using pieces of sources specified on level of control by
level of control basis. For example, a breakaway switch could specify
source VTR 1's video feed while not switching its audio feed.
Category
An alphanumeric string of characters from 1 to 6 characters long and
starting with an alpha letter. Categories comprise the first portion of the
name of a source, destination, or reentry. Categories provide an easy
means of classifying router input/output devices. An example of a
category is VTR which could be used to construct the names VTR 1, VTR
2, VTR 3, etc.
