JNIA
Jupiter Network Interface Application. A
program that supports operation of a Logger,
Log Viewer, Party Line Download software,
Physical Control (Switching), CP-3200, and
Force Unprotect/Unlock.
JNS
Jupiter Network Suite. A collection of many
programs designed as a replacement and en-
hancement to the
JNIA
software. Includes the
Router Save/Restore Utility, Physical Diag-
nostic Utility, Physical Remap ping Utility
(PRU) and the I/O Editor. The JNS also in-
cludes all the JNS

play, Router Control Utility, JNS Logger, JNS
Log Viewer, Force Unlock, Physical Control,
and Party Line Download.
JNS Servers
JNS programs that provide data to Jupiter
client programs in the same or other comput-
ers.
Jupiter
Compact, follow-on version of
BCS
-3000
CONTROL SYSTEM
. A PC-type computer is
used as the file server.
Jupiter XPress
Provides a limited set of Jupiter switching
and machine control functions using the CM-
4000 as the interface between Thomson Cros-
spoint Bus routers and certain control devic-
es.
L
level
Historically, a switcher matrix that carries
one type of signal, as determined by DIP
switch settings on crosspoint boards. Exam-
ple: level 1 for video, levels 2 and 4 for left
and right audio, etc. However, in 3-stage
switching systems this switch-set level is re-
ferred to as the “physical” level; and large
systems may require more than one physical
level to provide enough hardware for an en-
tire “logical” level (such as video). The Jupi-
ter Physical Switching menu refers to a
“logical level” that is actually the logical lev-
el
number, this being the row number on
which the level is identified on the Switcher
Level Descriptions table. The logical level
name also appears on this table.
linkage
Jupiter machine assignment function, where-
by control of a VTR is passed to a remote
panel. The system can be configured so that
linkage will occur automatically, based on
the signal from the VTR being switched to a
destination associated with that panel; this
function is sometimes described as “ma
chine control following the router.” Linkage
can also be accomplished manually, using
the MC-3020L Linkage panel. See also

lock
1. On Jupiter control panels equipped with a
LOCK button (except MC 3020L): after a giv-
en source has been switched to a given desti-
nation, and LOCK is pressed, the source for
that destination can then be changed only at
the panel which set the lock;
and only after
LOCK is pressed again. Note that a panel can
only lock
