Hello,
I work for a company that provides WAN connection to very large well known companies. I have always wondered what the difference is between an AIS alarm and a Remote alarm. The ones that I am speaking of are lised in the output when the following command is issued, "sh service-module serialx/x/x.
I know that the AIS alarm is an alarm from upstream beyond the frame switch, but what is the remote alarm for? I see it increment often at different sites.
Example:
0839wampls#sh service-module s0/3/0
Module type is T1/fractional
Hardware revision is 1.2, Software revision is 20060719,
Image checksum is 0x3EB2C1, Protocol revision is 0.1
Receiver has no alarms.
Framing is ESF, Line Code is B8ZS, Current clock source is line,
Fraction has 24 timeslots (64 Kbits/sec each), Net bandwidth is 1536 Kbits/sec.
Last module self-test (done at startup): Passed
Last clearing of alarm counters 03:54:55

loss of frame : 1, last occurred 03:54:45
AIS alarm : 1, last occurred 03:54:45 <------------------------------------------ AIS Alarm
