Description of command
This command is always a query. It indicates whether and in which way the tolerances for the bit error rate test
(see command above) have been exceeded. See also detailed explanation of measured values in chapter 4 and
table in section
BER Tests of PDTCHs .
The following messages can be output for the measured quantities:
PASS all tolerances matched
passed
FAIL Not all tolerances matched failed
INV Invalid measurement invalid
IMP Measurement impossible, therefore invalid
impossible
NMAU Tolerance exceeded not matching, underflow
INV Invalid measurement invalid
OK . all tolerances matched
