SET THRESHOLD T1
(SET-TH-T1)
MESSAGE CATEGORY: SURVEILLANCE
TYPE: INPUT/RESPONSE
This command sets the threshold level for a monitored parameter. When the parameter exceeds the
threshold value, an automatic message is sent. The threshold may apply to one or more units. One com-
mand is required for each threshold setting.
COMMAND
SET-TH-T1:[<tid>]:<aid>:<ctag>::<montype>,<thlev>;
aid: MRC-1-x = Multi-Reference Controller A (x = span 1 to 4 or ALL)
MRC-2-x = Multi-Reference Controller B (x = span 1 to 4 or ALL)
PSM-x-y = Precision Sync Monitor card (x = 1 to 9, y = span 1 to 4 or ALL)
montype: BPV = bipolar violations
CRC = cyclic redundancy check errors
OOF = out of frame errors
AIS = alarm indication signal
thlev: xxxxx = decimal numeral for the threshold level (max. 32767)
Note: If the aid is MRC-1-x or MRC-2-x, montypes BPV, CRC, OOF, and AIS are to be
used only if E1 is selected as the input; if analog is the input, the command will be denied.
montype: For PSM only:
MTIE1 = maximum time interval error at 1 second
MTIE4 = maximum time interval error at 4 seconds
MTIE16 = maximum time interval error at 16 seconds
MTIE64 = maximum time interval error at 64 seconds
MTIE128 = maximum time interval error at 128 seconds
MTIE512 = maximum time interval error at 512 seconds
MTIE900 = maximum time interval error at 900 seconds
TVAR1 = time variance error at 1 second
TVAR4 = time variance error at 4 seconds
TVAR16 = time variance error at 16 seconds
TVAR64 = time variance error at 64 seconds
TVAR128 = time variance error at 128 seconds
thlev: xxxxx = where xxxxx equals a decimal numeral for the threshold level
(max. 32767 nanoseconds)
Examples:
SET-TH-T1::MRC-1-3:135::OOF,20;
This example, if E1 is the input, tagged as command 135, sets the out of frame errors of MRC-1,
span 3, to 20.
This example, if analog is the input, will be denied, and an IDNV error code produced.
