TRX级：

7743告警：

JANBSC22G BCF-0283 BTS-0583 QUAL 2009-04-01 12:14:59.87 ** ALARM TRX -004 JACXBAOYUYUA1E

(30042) 7743 MEAN HOLDING TIME BELOW DEFINED THRESHOLD 01 00 00 00 01 01 01 00 04 02 8d

主要是由于GPRS告警引起，不会对掉话率有什么影响，可能会影响彩信、GPRS激活成功率、GPRS掉话率等，处理方式同7745告警。

7745告警：

JANBSC22G BCF-0174 BTS-0176 QUAL 2009-03-28 08:15:03.12 ** ALARM TRX -009 JACXZHENGBJ3

(27326) 7745 CHANNEL FAILURE RATE ABOVE DEFINED THRESHOLD 01 00 00 00 01 00 00 00 00 03 02 20d

01 00 00 00 01 00 00 00 00 03 02 20d

其中头位数表示：01表示TCH 02表示SDCCH 第二到第九位数表示一块载频8个时隙，00正常，01掉话 第十位指出掉话时隙

当02时，表示SDCCH掉话率高，查看SDCCH掉话原因，大部分可能为BSC数据错或MSC数据定义有误造成。

当01时，表示TCH掉话率高，最后一位表示载频由于信道失败的掉话占整个载频掉话总数的百分比，如该值超过30％，可考虑重启载频、扇区、BCF。如重启后仍然存在过多的7745告警，并且小区总体掉话率依然偏高（无直放站情况下大于8％的掉话率）建议更换载频版或BB2板，一般能解决。

7606告警：

JANBSC22G BCF-0004 BTS-0305 EQUIPM 2009-03-24 02:13:42.62 ** ALARM TRX -007 JACXSHENGANCU2E

(24260) 7606 TRX FAULTY The transmitter output power is too low. 05 02 07 98 00 00

7606一般为载频退服告警，有不同的告警提示，The transmitter output power is too low.载频输出电平过低，载频故障，一般更换载频即可，故障代码：05 02 07 98 00 00，第四位98指出故障或故障相关板件，98一般为TSxx，96 一般为BOI，97为BB2，9A为RTxx，9B为DUxx，详见附表1，可根据告警提示信息和代码进行故障定位处理。

7607告警：

JANBSC02G BCF-0247 BTS-0247 EQUIPM 2009-03-04 00:16:25.82 ** ALARM TRX -006 SHXXTANGYUCL1

(10241) 7607 TRX OPERATION DEGRADED Performance is degraded in 1st branch dual variable gain duplex unit. 06 02 03 9B 00 00

载频级告警，7607告警一般指向合路器单元 ，同一合路器所带载频一般都会出现此告警，代码指向和7606告警一样，9B为DVGA，根据告警指示信息可定位为合路器DVGA故障。

7725告警：

JANBSC17G BCF-0094 BTS-0093 EQUIPM 2009-03-31 20:08:38.72 ** ALARM TRX -003 SHXNYUTIAN2 RTSL-007

(51454) 7725 TRAFFIC CHANNEL ACTIVATION FAILURE 02

TCH信道激活启动失败告警，一般重启载频及相应时隙告警可消失，如无法消除可检查硬件故障，更换该载频。

7735告警：

JANBSC22G BCF-0030 BTS-0030 EQUIPM 2009-03-08 23:24:45.73 ** ALARM TRX -001 JACXCAIYOUJI1

(15075) 7735 TRX TEST FAILED 2d 46d 255d 00000000 112d 00000000 111d

载频测试失败告警。

7741告警：

JANBSC01G BCF-0237 BTS-0237 QUAL 2009-03-09 04:11:19.35 ** ALARM TRX -001 YIXXDONGSHANGX1 RTSL-003

(47863) 7741 MEAN HOLDING TIME ABOVE DEFINED THRESHOLD F0 120d 1d 7212d

重启相应载频及时隙。
