Description
Causes HiGain to transmit the AIS signal at both the HLU and HRU
T1 output ports when both of the HDSL loops are not in sync
(LOSW).
Causes HiGain to transmit the AIS signal at both the HLU and HRU
T1 output ports when either of the two HDSL loops is not in sync
(LOSW) or if a minor alarm occurs.
Causes the HRU to transmit the AIS signal toward the CI when in
NREM loopback.
Prevents the AIS signal from being transmitted to the NI and
replaces it with the network test signal, if an HRU List 6 or 8 is
detected, or by a quiet termination (LOS), if an HRU List 7 is
detected.
The MARG (Margin Alarm Threshold) can only be set using the
Maintenance Terminal menus. This setting determines the
minimum allowable margin below which a minor alarm can occur.
A 0 dB setting disables this option. Default setting is 1 dB.
The DS0 Blocking Option can only be set using the Maintenance
Terminal menus. The four-character front panel display only
displays the status of the blocking option. BLK indicates at least
one channel is blocked. Blocked channels are replaced by the FF
Idle Code.
Indicates no channels are blocked.
