5-33Parameterst3-number: Number of a T3 channel on the current CPOS interface, in the range of 1 to 3.detect: Enables/disables periodical alarm signal detection on the specified T3 interface. By default,periodical alarm detection is enabled.generate: Generates and sends a specific type of alarm signals, which can be AIS, RAI, IDLE, or FEBE.These alarm signals are used for line status test. By default, alarm signal sending is disabled.z ais: Alarm indication signal.z febe: Far-end block error.z idle: Idle signal.z rai: Remote alarm indication.DescriptionUse the t3 set alarm command to enable alarm signal detection or sending on the specified T3channel.Use the undo t3 set alarm command to restore the default.You can enable alarm detection or sending of a type of alarm signals on a T3 channel to check its linestate.At startup of your router, periodical alarm signal detection is enabled on T3 channels. When detectingLOS, LOF, or AIS signals, a T3 channel sends RAI signals to its peer. Alarm state report for the interfaceis real time; you can view that by executing the display controller cpos t3 command.The supported alarm signals, LOS, LOF, AIS, RAI, FEBE, and idle, are ANSI T1.107-1995 compliant.Only a type of alarm signal can be sent on a T3 channel at a time. To have the T3 channel send anothertype of signal, use the undo t3 set alarm command to delete the previous setting first. In addition, whenan RAI signal generated upon detection of a LOS, LOF, or AIS signal is present, the T3 channel cannotsend another type of signal. To do that, use the undo t3 set alarm detect command to disable the T3channel to send the RAI signal generated after detecting an alarm first.Examples# Enable alarm signal detection on T3 channel 2 of CPOS 2/0/0. system-view[Sysname] controller cpos 2/0/0[Sysname-Cpos2/0/0] t3 2 alarm detect# Enable T3 channel 2 of CPOS 2/0/0 to generate AIS alarm signals. system-view[Sysname] controller CPOS 2/0/0[Sysname-Cpos2/0/0] t3 2 alarm generate aist3 set bertSyntaxt3 t3-number set bert pattern { 2^7 | 2^11 | 2^15 | qrss } time numberundo t3 t3-number set bert patternViewCPOS interface view
