remote-alarm [rai | ais]
The
remote-alarm
command selects the alarm signaling type to be sent when a loss of frame is detected
on the E1 receive signal. Use the
no
form of this command to disable all transmitted alarms.
Syntax Description
rai
Specifies sending a remote alarm indication (RAI) in response to a loss of frame.
Also prevents received RAI from causing a change in interface operational status.
ais
Specifies sending an alarm indication signal (AIS) as an unframed all-ones signal.
Default Values
The default for this command is rai.
Functional Notes
An E1 will respond to a loss of frame on the receive signal by transmitting a remote alarm to the far end to
indicate the error condition. TS0 of an E1 contains the Frame Alignment Signal (FAS) in the
even-numbered frames. The odd-numbered frames are not used for frame alignment, and some of those
bits are labeled as spare bits (SA bits) in bit positions 4 through 8.
Usage Examples
The following example enables transmission of AIS in response to a loss of frame:
ProCurve(config)#
interface e1 1/1
ProCurve(config-e1 1/1)#
remote alarm ais
