Overhead sequence generation: A
single overhead channel is overwritten
with a single or repeated sequence of
programmed values. Alternatively a
BER test can be performed on a
selected byte of regenerator,
multiplexer section or path overhead.
MSP message generation: Messages
are displayed in text form as per ITU-T
G.783. Also user programmed
sequences.
DCC insert/drop: Data supplied to the
DCC port can be inserted into either the
regenerator section (192 kb/s) or
multiplexer section (576 kb/s)
communications channel. Similarly,
data can be dropped from either. Data
may be inserted/dropped MSB or LSB
first.
STM-1 optical interface stress test:
2 to 259 bytes of the payload are
overwritten with a block of zeros (or
ones for NRZ systems) after
scrambling. Alternatively the ITU-T
G.958 test can be selected.
STM-1 thru mode:
Transparent mode: The signal is
passed through the instrument
unaltered.
Overhead overwrite mode: The test
features associated with MSOH and
POH can be enabled in order to control
one single or multi byte overhead
channel.
AU-4 overwrite mode: Overwrite the
complete AU-4 with the internally
generated payload.This enables the
SOH to be looped through while a new
payload is inserted. All of the test
features which affect the VC-4 and/or
the POH are enabled.
Equalization: Automatic for cable loss
up to 12 dB at half the bit rate.
Monitor point compensation: 20 or
26 dB
Pointer detection: AU-4, TU-3 and
TU-12 pointer values.
