Description: This is an encoded representation of the alarm to be reported. The format of the encoded data is as follows : octet[0] umc1CurAlmDetails IMPLEMENTATION VERSION. This will be used to identify the structure of the following data. For IMPLEMENTATION VERSION equal 1 the following data within umc1CurAlmDetails be of the form: octet[1] UMC eFacAlarm value for this alarm/event (High 8-bits). octet[2] UMC eFacAlarm value for this alarm/event (Low 8-bits). octet[3] category (SET=1, CLEAR=2, EVENT=3) octet[4] severity (CRITICAL=1, MAJOR=2, MINOR=3, EVENT=4, STATUS=5) octet[5] PLUG IN TYPE this alarm was generated for (High 8-bits). octet[6] PLUG IN TYPE this alarm was generated for (Low 8-bits).

octet[7] alarm misc byte[0] octet[8] alarm misc byte[1] octet[9] alarm misc byte[2] octet[10] alarm misc byte[3]

octet[11] LOCATION_TYPE - indicates the format of the following 4 octets of information. The valid values for this field are listed below: 0 = Invalid_data 1 = Term_valid 2 = Shelf_valid 3 = Slot_valid 4 = Circuit_valid 5 = Group_valid The contents of the following four octets for each of these types is detailed below.

LOCATION_TYPE equals Invalid_data octet[12] unused - set to zero octet[13] unused - set to zero octet[14] unused - set to zero octet[15] unused - set to zero

LOCATION_TYPE equals Term_valid octet[12] LOCATION - Terminal number (LET = 1, RST1 = 2, RST2 = 3, etc.) octet[13] unused - set to zero octet[14] unused - set to zero octet[15] unused - set to zero

LOCATION_TYPE equals Shelf_valid octet[12] LOCATION - Terminal number (LET = 1, RST1 = 2, RST2 = 3, etc.) octet[13] LOCATION - Terminal shelf number octet[14] unused - set to zero octet[15] unused - set to zero

LOCATION_TYPE equals Slot_valid octet[12] LOCATION - Terminal number (LET = 1, RST1 = 2, RST2 = 3, etc.) octet[13] LOCATION - Terminal shelf number octet[14] LOCATION - Shelf slot number octet[15] unused - set to zero

LOCATION_TYPE equals Circuit_valid octet[12] LOCATION - Terminal number (LET = 1, RST1 = 2, RST2 = 3, etc.) octet[13] LOCATION - Terminal shelf number octet[14] LOCATION - Shelf slot number octet[15] LOCATION - Slot circuit number (0 = circuit 0

LOCATION_TYPE equals Group_valid octet[12] LOCATION - Terminal number (LET = 1, RST1 = 2, RST2 = 3, etc.) octet[13] TR08/TR303/etc. Group number (High 8-bits) octet[14] TR08/TR303/etc. Group number (Low 8-bits) octet[15] unused - set to zero

octet[16] COORELATION TAG - High 8-bits of the YEAR octet[17] COORELATION TAG - Low 8-bits of the YEAR octet[18] COORELATION TAG - Month (January=1, February=2, etc.) octet[19] COORELATION TAG - Day (1 through 31) octet[20] COORELATION TAG - Hour (0 through 23) octet[21] COORELATION TAG - Minutes (0 through 59) octet[22] COORELATION TAG - Seconds (0 through 59) octet[23] COORELATION TAG - mSec (0 through 255). mSec is an index to differentiate this alarm from any others that may have occurred in the same second.

octet[24] Term name length in octets, (eg, 10 if the terminal name is 130 W. Elm).

octet[25] to Term name string. eTNL = (25+Term name length). octet[eTNL]

octet[eTNL] RAI/Environmental alarm description string length in octets. This is an OPTIONAL string used to present additional information about RAI or External ALARMS. If the alarm is of one of the types that supports user defined descriptions in the UMC system, that description will be contained in the following string. If it isnt, or there was no user defined string, this byte will be set to zero.

octet[eTNL + 1] to Environmental alarm description string. octet[eEADSTR] eEADSTR = ((eTNL + 1) + RAI/External Alarm description string length).
