transmit overhead BER test function.
Error count, error ratio, error free
seconds, percentage error free seconds
and pattern loss seconds are calculated

Safety classification: Class 3A, FDA
21 CFR Ch.1 1040.10 and EN 60825
Clock timing: Internal, recovered from
received STM-0, STM-1 or STM-4
optical, electrical or binary signal,
1-40
external MTS - data or clock format (as
ITU-T G.811)
Frequency offset generation: Up to
999 ppm in 0.1 ppm steps
VC-4-4C error add: B3 BIP, HP REI,
-4

HP IEC - 10
to 10
, Bit - 10
VC-4-4C alarm generation: AU-AIS,
HP-RDI, AU-LOP, Path Unequipped
STM-4 error add: Frame - single and
N in 4 frame words, B1 BIP - 10

, B2 BIP and RS REI - 10
STM-4 alarm generation: Loss of
signal, loss of frame, out of frame,
multiplexer section AIS, multiplexer
section RDI.
STM-4 thru mode:
Transparent mode: The STM-4
signal is passed through the HP 37717B
without being altered. The BIP's are not
recalculated.
Overhead overwrite STM-4 mode:
The test features associated with the
section overhead can be enabled in
order to control one single or multi byte
overhead channel. The B1 and B2 bytes
are recalculated.
Overhead overwrite STM-4-4C
mode: The test features associated with
the section overhead and path overhead
can be enabled in order to control one
single or multi byte overhead channel.
The B1, B2 and B3 bytes are
recalculated.
AU-4 overwrite mode: Overwrite the
complete AU-4 with the internally
generated payload. This enables the
SOH and the three background AU-4's
to be looped through while a new
payload is inserted into the STM-1
under test. All of the test features which
affect the VC-4 and/or the POH are
