Glossary
HI-33110 - precursor to HI-33200 SD/HD
Input Module. Consists of a 16-input
base board (HI-33110) and a 16-input
mezzanine board (HI-33011), provid-
ing 32 inputs. The module supports
data rates of 3 Mbps to 1.485 Gbps. A
“gain cell” is included on this board to
be used in conjunction with the port
expanders in order to create multi-
frame routers.
Level - historically, a switcher matrix that
carries one type of signal, as deter-
mined by Dual In-line Package (DIP)
switch settings on crosspoint boards.
Example: 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 referred to as the
“physical” level; and large systems
may require more than one physical
level to provide enough hardware for
an entire “logical” level (such as
video). The Jupiter Physical Switching
menu refers to a “logical level” that is
actually the logical level 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.

OPM - OUTPUT MONITOR .
Output Monitoring - feature of routing
switcher which allows control system
to verify switcher performance with-
out interrupting normal operations. A
separate, internal switching system is
used to switch the Monitor Output to
any output of the switcher.
physical level - see LEVEL .
Refresh - continuous repetition of switch-
ing instructions and confirmation of
crosspoint status. Reports any inter-
ruption of service – for example, if
crosspoint board is removed. When
board is replaced, automatically
restores previous switch instructions.
