Glossary
Note: terms set in SMALL CAPS are defined
within this glossary.
10Base2
Coax version of ETHERNET . Uses a 4.9 mm
(0.19 inch) diameter, 50-ohm coaxial cable
(RG-58) and BNC connectors, but runs at the
same speed (10Mb/s) as
ETHERNET . The Jupi-
ter system uses this standard between VM/
SI controllers and Saturn. It is also used by
the original BCS 3000 controllers.
10/100BaseT
ETHERNET configuration that uses twisted
pair wiring (typically Cat 5 UTP unshielded
twisted pair cable with RJ45 8-pin connec-
tors) to transmit data up to 100 Mbps.
4000 series
These products are very similar to the 3000
and 3500 series products but have the “cres-
cent” style front panel.
A
AccuSwitch
Control application for CM-4000. Provides
interface between Thomson Crosspoint Bus
routers and certain automation systems, in-
cluding Thomson Broadcast Automation.
AES
Audio Engineering Society. Internet address:
http://www.aes.org.
AES3-1992
AES Recommended Practice for Digital Au-
dio Engineering -- Serial transmission format
for two-channel linearly represented digital
audio data.
AES11
AES Recommended Practice for digital au-
dio engineering -- Synchronization of digital
audio equipment in studio operations.
AFV
Audio-Follow-Video. Normal operation of a
distribution switcher where selection of a
video source automatically selects audio
from that source. Example: selection of VTR1
video automatically selects VTR1 Audio 1
and VTR1 Audio 2 as well.
B
binary super crosspoint bus
Similar to super crosspoint bus, but the units
digits are allowed to cover the range of 0 to F,
rather than 0-9 as in previous switcher sys-
tems. Generated only by the Jupiter, CE-
2500, and BCS-3000 control systems.
breakaway
Independent operation of a switcher level.
Same as “split.” Contrasts with normal AFV
operation. Example: selecting video from
VTR1 but audio from Announce Booth 2.
bus
In distribution switching, a channel leading
to an output or destination. Example: “con-
trols 20 buses” means being able to select
sources for 20 destinations.
button-per-input/output control panel
Buttons are dedicated to a particular source
or destination. As opposed to
CATEGORY /
NUMBER control.
