S1240在正常运行中,经常会打印出各种不同类型的传输告警报告。机房值机人员由于对各类传输告警性质不清楚.所以往在一出现传输告警后,迷惑不解,有时显得很紧张不知如何处理。传输告警一般分三种类型:第一种,正常告警,例如;入中继无信号告警(LIS ALARM);第二种,非紧急告警,例如远端告警(RJAALARM),RSADKALARM;第三种,紧急告警,例如LFA、LMA、AIS、ERR告警等。为了提高S1240长话市话中继接通率,减少不必要的呼损,本文对各种传输告警提一些看法、供参考。 1.入中继无信号告警(LIS ALARM即lossincoming signal alarm) 在S 1240运行中,一般中继电路均有一定富裕度,总有一些中继模块留作备用。由于空闲模块未接
In normal operation, S1240 often reports various types of transmission alarm reports. Machine room check-in personnel because of the nature of various types of transmission alarm is not clear, so in the event of a transmission alarm, puzzled, and sometimes seem nervous I do not know how to deal with. There are three types of transmission alarms: type one, normal alarms, for example, LIS ALARM; type two, non-emergency alarms such as RJAALARM and RSADKALARM; type three, Emergency alerts, such as LFA, LMA, AIS, ERR alarms, etc. In order to increase the call relay rate of S1240 long distance calls and reduce unnecessary call losses, this paper gives some opinions for various transmission alarms for reference. 1. Into the relay signalless alarm (LIS ALARM ie lossincoming signal alarm) In S 1240 operation, the general relay circuit has a certain amount of margin, there are always some relay modules reserved for backup. Idle module is not connected
