TTL Type
The type of terminating test line on the switch at the far end of the trunk
to which the test call was made.
Threshold
Values
The list of marginal and unacceptable threshold values for each type of
measurement. These are defined on the trunk group form.
Trk Mem
The trunk member number.
Test Date
The month and day this trunk was last tested.
Test Time
The time of day this trunk was last tested.
Tst Rslt
The results of the trunk transmission test as follows:
pass
The test call completed successfully and trunk performance was
satisfactory
marg
Trunk measurements exceeded the marginal threshold, but not the
unacceptable.
fail
Trunk measurements exceeded the unacceptable threshold.
xxxx
A numerical error code indicates the reason for an aborted test call. The
codes are explained in the CO-TRK and TIE-TRK sections of Chapter 9,
‘‘ABRI-PORT (ASAI ISDN-BRI Port)’’.
blank
A blank line indicates that no measurements have been made on this
trunk since the database was last initialized.
1004Hz-los
s Min
Far-to-near and near-to-far measurements of 1004-Hz loss from low-level
tone.
1004Hz-los
s Max
Far-to-near and near-to-far measurements of 1004-Hz loss at 0 dBm.
Loss dev
at 404Hz
These low-frequency transmission tests measure maximum positive and
negative deviation of +9 and -9 dB from the 1004-Hz loss
measurements.
Loss dev
at 2804Hz
These high frequency transmission tests measure maximum positive and
negative deviation of +9 and -9 dB from the 1004-Hz loss
measurements.
C-msg
Noise
Maximum noise interference noise) terminating on a voice terminal within
the voice-band frequency range (500 to 2500 Hz). The measurement
ranges from 15 to 55 dBrnC (decibels above reference noise).
C-ntch
Noise
Maximum signal-dependent noise interference on a line between 34 and
74 dBrnC.
