the T1 output signal level from the HRU towards the
NI to 0 dB. This setting is recommended when the

to en external NID. It allows the external NID to set
the appropriate NI level.

the T1 output signal level from the HRU towards the
NI level to -15 dB. This setting is recommended
when the HRU functions as the NID.
