Glossary 41
Index
The last portion of a source, destination, or reentry name.
Indices provide an easy means of differentiating similar switching system devices.
Each source, destination or reentry name may use 0, 1 or 2 indices. If no index is used, “00” is the
default but is not displayed. An example of indices are 1, 2, and 3 which could be used with the
category VTR to create the destination names VTR 1, VTR 2, VTR 3, VTR 12 and VTR 22.
Indices are one character in length and are constructed using uppercase letters and numbers. The
character 0 (zero) is a default index which may not be changed or deleted.
Input Offset
In matrix space, the amount by which the origin of a component on strobe x, is offset from the
origin of strobe x, measured along the input axis.
The coordinates of crosspoints in matrix space are determined by the strobe they reside on, and
their input and output numbers. They are given in the form (input,output) on strobe x. The origin
of a component (a matrix of crosspoints) is designated by the point which falls nearest the origin
of its strobe (1,1). In Figure A below, the 3x4 component bounded by coordinates (3,2), (5,2),
(5,5), and (3,5) has its origin at (3,2).
Figure A
Input offset is the amount by which the origin of a component is offset from the origin of its
strobe, measured along the input axis. A component whose origin coincides with that of its strobe
(1,1) will have an input offset of 0. The component shown in Figure A above, has an input offset
of 2.
When multiple routing switchers are assigned to the same strobe, the input and output connectors
are renumbered to provide a unique coordinate for each crosspoint. Crosspoint coordinates are
then determined in the same manner as above. The component shown in Figure B below, has its
origin at (12,7) and an input offset of 11.
