Glossary

output monitoring

Feature of routing switcher which allows

control system to verify switcher perfor-

mance without interrupting normal opera-

tions. A separate, internal switching system

is used to switch the Monitor Output to any

output of the switcher.

P

path finding

Switching technique allowing two or more

TVS/TAS-2000 or later routing switchers to

operate as a system, where each switcher can

access the other's inputs through a number of

tie lines. Be cause the tie lines are limited, the

path will be blocked when all lines are busy.

Not to be confused with

THREE-STAGE

S

WITCHING.

PCI

Peripheral Component Interconnect, a local

computer bus standard developed by Intel

Corporation. Most PCs include a PCI bus in

addition to a more general ISA expansion

bus.

physical level

see LEVEL.

PL board

PL-3000 Party Line Interface.

Pmem

Battery-protected memory.

polling

Communication technique where central

controller polls (addresses) each device on a

party line in turn. When so addressed, a par-

ticular device can then send or receive data

without being interrupted.

polling name

Unique address assigned to a switcher con-

trol panel. When transmitted by the polling

and control card, allows communication be-

tween that panel and the switcher matrix.

PPM

Peak program meter.

protect

On Jupiter control panels with a PROTECT

button: after a given source has been

switched to a given destination, and PRO-

TECT is pressed, the source for that destina-

tion can then be changed only at the panel

which protected the output. Note that a pan-

el can only protect

LEVELS that are assigned to

the panel during configuration. See also

LOCK, and FORCE UNPROTECT/UNLOCK.

primary status instruction

In Jupiter systems, a configuration technique

used in the CP Input set for display of S

PLIT

M

NEMONICS. Indirect (“I”) entries are used to

point to a primary (“P”) entry. The primary

entry in turn points to the desired mnemonic

for that level.

R

refresh

Continuous repetition of switching instruc-

tions and confirmation of crosspoint status.

Reports any interruption of service – for ex-

ample, if crosspoint board is removed. When

board is replaced, automatically restores pre-

vious switch instructions.

REM

Reference, expansion, monitor. Internal

name for MX-33000 Matrix board.

remote PC

PC on a Jupiter LAN in addition to the PC

used as the file server. Can be used for auxil-

iary tasks such as remote

LOGGING.
