Hello folks,
I am working a project that we need to implement DS1 MIB. However, there are
some disagreements among fellow engineers regarding the definitions of DS1 far
end table. Hope someone can spare some time and help us out.
Based on RFC2495/3895, the description for dsx1FarEndCurrentTable is :
----------------------------------------------------------------------------
dsx1FarEndCurrentTable OBJECT-TYPE
SYNTAX SEQUENCE OF Dsx1FarEndCurrentEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The DS1 Far End Current table contains various
statistics being collected for the current 15
minute interval. The statistics are collected
from the far end messages on the Facilities Data
Link. The definitions are the same as described
for the near-end information."
::= { ds1 10 }
---------------------------------------------------------------------------
The major disagreement is that for some fellow engineers, the far end
statistics such as dsx1FarEndCurrentESs is derived only from DS1 FDL. So if DS1
FDL is disabled, there is no far end statistics to be reported at all. Whereas
some engineers think that the far end statistics should be derived from either
FDL or yellow alarm. So even though FDL is disabled, as long as yellow alarm is
present, far end statistics like dsx1FarEndCurrentESs should still be valid and
reported. We also looked into ANSI T1.231.02-2003 as well as GR.820 for
references. What says in ANSI T1.231 and GR.820 is inline with the idea that
far end statistics should be derived from either FDL or yellow alarm. What is
the right interpretation though? Far end statistics should be from FDL only or
it can be derived from either FDL or RAI?
Your help is greatly appreciated!!!
James
