CHANNEL FAILURE RATE ABOVE DEFINED THRESHOLD
01 00 00 01 01 01 01 01 01 03 02 47d

Can anyone tell me what is “47d” in above description.

7745 CHANNEL FAILURE RATE ABOVE DEFINED THRESHOLD
Meaning
The rate of calls terminating in failure on a channel is above the
threshold value set by the operator. The alarm is used to supervise
the functioning of traffic and signaling channels, and to detect
the possible faulty channels.
Supplementary information fields
1 indicates if the alarm is on the TCH or on the SDCCH channel
01: TCH
02: SDCCH

2 indicates if the channel failure rate is above the defined
threshold in time slot 0
00: belove threshold (no alarm)
01: above threshold (alarm)

3 indicates if the channel failure rate is above the defined
threshold in time slot 1
00: belove threshold (no alarm)
01: above threshold (alarm)

4 indicates if the channel failure rate is above the defined
threshold in time slot 2
00: belove threshold (no alarm)
01: above threshold (alarm)

5 indicates if the channel failure rate is above the defined
threshold in time slot 3
00: belove threshold (no alarm)
01: above threshold (alarm)

6 indicates if the channel failure rate is above the defined
threshold in time slot 4
00: belove threshold (no alarm)
01: above threshold (alarm)

7 indicates if the channel failure rate is above the defined
threshold in time slot 5
00: belove threshold (no alarm)
01: above threshold (alarm)

8 indicates if the channel failure rate is above the defined
threshold in time slot 6
00: belove threshold (no alarm)
01: above threshold (alarm)

9 indicates if the channel failure rate is above the defined
threshold in time slot 7
00: belove threshold (no alarm)
01: above threshold (alarm)

10 time slot with the highest failure rate

11 subchannel identification TCH:
00: TCH/H -subchannel 0
01: TCH/H -subchannel 1
02: TCH/F -subchannel

subchannel identification SDCCH:
00 – 07: SDCCH -subchannel 0 – 7

12 proportion of TCH or SDCCH subchannel releases due to failure
in all channel releases on a given channel during the measurement
period
