3450 Hz at 0 dBm0)
Receive to transmit crosstalk
(input signal 200 Hz to
3450 Hz at 0 dBm0)
Inter channel crosstalk, TX
and RX direction.
Input 200 to 3450 Hz at
0 dBm0 at VFXI of one
channel; all other VFXI inputs
and all DR inputs receive idle
signal. Output is measured at
DX of the 3 idle channels.
Input of 200 to 3450 Hz at
0 dBm0 PCM at DR on one
channel. All other DR inputs
and all VFXI inputs receive
idle signal. Output is
measured at VFRO of the 3
idle channels
