lpDS1RaiAlarmType 1.3.6.1.4.1.562.2.4.1.12.7.10.1.4

This attribute defines the method of sending a RAI (Remote Alarm Indication) alarm on a DS1 line. When SBit is selected, RAI alarm is sent by setting the S bit in frame 12. When Bit2 is selected, RAI alarm is sent by setting bit 2 in all timeslots to 0. When fdl is selected, RAI alarm is sent by a repeating pattern of 00 hex and FF hex on the FDL link. Note that for lineType of d4, only the SBit and the Bit2 methods are applicable. Whereas for lineType of esf, only the Bit2 and the fdl methods are applicable. SBit method is recommended if lineType is set to d4 and zeroCoding is set to ami. This will help to avoid potential mimic RAI alarm when 1's density is too low in the data transmitted. For cell-based cards only the default value fdl is permitted.
