• Incoming 64k all bear: the instrument waits for a call from a remote device.
As soon as a call is received, the instrument answers automatically and
starts to generate the PRBS and measure the BER according to the set
pseudorandom sequence.

In ‘Incoming 64k all bear’, the test equipment can be used as an
automatic answer remote machine, which activates every kind of
incoming call an performs a BER test with generation and
measure of the PRBS sequence.

Bit Sequence: Set the pseudo-random bit sequence to be used from the list or
define your own pattern.

Pass/Fail Test: Choose the BER value. This value is used to determine the pass or
fail test condition. Use E-7 (10-7) when no other value is requested. The G.821 value
calculates the acceptability threshold according to the performance target expected
by the G.821 recommendation. The HRX(%) parameter modifies such threshold.

Error Injection: Insert the number of errored bits which the device sends on line. It is
possible to use both manual and automatic mode. In automatic mode, you need to
insert the BER value to be sent.

SES Threshold: Choose the number of errors per second in order to consider the
second as Severely Errored. Use the G.821 default value, corresponding at 10-3
when no specific value is requested.

DM Threshold: Choose the number of errors per minute in order to consider the
minute ad Degraded. Use the G.821 default value when no specific value is
requested. In the last G.821 recommendation issue, DM result has been cancelled
from the recommendation but, the device implements the DM measure anyway.

HRX(%): Enter the variation percentage for the acceptability threshold according to
the type of call (e.g. National or International).

If test fails then: Select the action to be taken by the device in case of threshold
acceptability overcoming. You can choose between maintaining the connection
active, disconnecting it, or continuing the test in progress even in case of threshold
acceptability overcoming. Used for call routing search.
