11. TRANSMISSION
.
General
11.01 This Part specifies the PBX transmission characteristics.
Transmission
11.02 The insertion loss at 1004 Hz is as follows:
Line-to-Line connection: 4.5 to 5.5 dB average with a maximum
0.3 dB variation between paths.
Line-to-Trunk connection: 0.0 to 0.5 dB average with a maxi-
mum 0.3 dB variation between paths.
Trunk-to-Trunk connection: 0.0 to 0.5 dB average with a maxi-
mum 0.3 dB variation between paths.
The attenuation variation, relative to the 1004 Hz insertion loss, does
not exceed the limits as shown in Table 1 l-l.
11.03 Harmonic Distortion.
the second or third harmonic shall not exceed a level of - 55
11.04 Intermodulation Distortion.
900 Hz and 1004 Hz, each at -13 dBm, the rms sum of all the
intermodulation products shall not exceed -50 dBm when measured at
the output.
