This field describes the results of the trunk transmission test.
1004Hz-loss Min
Far-to-near and near-to-far measurements of 1004-Hz loss from
low-level tone.
1004Hz-loss Max
Far-to-near and near-to-far measurements of 1004-Hz loss at 0
dBm.
Loss dev at 404Hz
Transmission tests at low frequency. These tests measure a
maximum positive and negative deviation of +9 and -9 dB from
the 1004-Hz loss measurements.
Loss dev at 2804Hz
Transmission tests at high frequency. These tests measure a
maximum positive and negative deviation of +9 and -9 dB from
the 1004-Hz loss measurements.
C-msg Noise
Maximum noise interference (in dBrnC: decibels above reference
noise, which is B(EQ)10 sup -12E(EQ) watts) terminating on a
voice terminal within the voice-band frequency range (500 to
2500 Hz) between 15 and 55 dBrnC.
C-ntch Noise
Maximum signal-dependent noise interference on a line between
34 and 74 dBrnC.
SRL-LO
Singing return loss from 0 to 40 dB between the sum of the circuit
(repeater) gains and the sum of the circuit losses. SRL-LO occurs
most often in the frequency range of 200 to 500 Hz.
SRL-HI
Singing return loss from 0 to 40 dB between the sum of the circuit
(repeater) gains on a circuit and the sum of the circuit losses.
SRL-HI occurs most often in the frequency range of 2500 to 3200
Hz.
ERL
Echo return loss from 0 to 40 dB between the level of signal
strength transmitted and the level of signal strength reflected.
ERL occurs most often in the frequency range of 500 to 2500 Hz.
