INTERCEPTOR 147 2 Mbit/s and Data Analyzer
2^20-1
1,048,575-bit pseudorandom pattern with a maximum
of 19 sequential zeros and 20 sequential ones (as
described in CCITT Recommendation V.57).
2^23-1
8,388,607-bit pseudorandom pattern with a maximum
of 22 sequential zeros and 23 sequential ones (as
described in CCITT Recommendation O.151).
QRSS
Quasi-Random Signal Source. 220-1 pattern modified
to transmit a maximum of 14 consecutive zeros.
TS BYTE
Timeslot Byte. User-programmable 8-bit byte inserted
(byte-aligned) into every selected timeslot. To
program this byte, use the TS Byte item. (When Test
is set to DATA, the TS BYTE pattern is not available.)
PRGM
User-programmable pattern (1 to 24 bits). To program
this pattern, use the Program Pattern item. (PRGM is
available if Test is set to 2M or DATA.)
DELAY
Delay is the pattern that is transmitted when round
trip delay is being calculated. (The DELAY pattern
is not valid when Test is set to MUX or the Transmitter
is OFF.)
FOX
FOX is the standard teleprinter test pattern: THE
QUICK BROWN FOX JUMPS OVER THE LAZY
DOG 1234567890, followed by the nonprintable
characters: carriage return and linefeed.
(The FOX pattern is available only if Intf is set to V.24
ASYNC. FOX never actually appears as a selection,
but it is automatically used when Intf is set to V.24
ASYNC.)
