R3102-R3103-HP 6600/HSR6600 Routers Interface Command Reference

240
• In framed mode, 24 timeslots of a T1 channel can be bound randomly to form serial interfaces.
Examples
# Set T1 channel 3 on interface CPOS 2/0/0 to operate in unframed mode.
<Sysname> system-view
[Sysname] controller cpos 2/0/0
[Sysname-Cpos2/0/0] t1 3 unframed
t3 set alarm
Use t3 set alarm to enable alarm signal detection or sending on the specified T3 channel.
Use undo t3 set alarm to restore the default.
Syntax
t3 t3-number set alarm { detect | generate { ais | febe | idle | rai } }
undo t3 t3-number set alarm { detect | generate { ais | febe | idle | rai } }
Default
Periodical alarm detection and alarm signal sending is enabled.

Default command level
2: System level
Parameters
t3-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.
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. ais: Alarm indication signal.
• febe: Far-end block error.
• idle: Idle signal.
• rai: Remote alarm indication.
Usage guidelines
You can enable alarm detection or sending of a type of alarm signals on a T3 channel to check its line
state.
At startup of your device, periodical alarm signal detection is enabled on T3 channels. When detecting
LOS, LOF, or AIS signals, a T3 channel sends RAI signals to its peer. Alarm state report for the interface
is 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 another
type of signal, use the undo t3 set alarm command to delete the previous setting first. In addition, when
an RAI signal generated upon detection of a LOS, LOF, or AIS signal is present, the T3 channel cannot
send another type of signal. To do that, use the undo t3 set alarm detect command to disable the T3
channel to send the RAI signal generated after detecting an alarm first.
