• The reported status code
-1*91414;13*1
can be analyzed as following:
The format is:
,.,..,.\1.0i14.
_ ( _ in our example) is the field name of NCP control blocks.
For SOLC lines, it is LXBSTAT/LXBSTATC, for pre-SNA lines, it is
IOBSTAT. Refer to NCP and EP Reference Summary and Data Areas
L Y30-5603 for explanations.
DI (iii
in our example) is the LCS code (Line Communication Status)
which is always foUowed by an ELCS code (Extended Line
Communication Status).
EEl (mIl·
in our example) is the ELCS code which means 'answer tone
not detected'.
a (m
in our example) may be either 0 or any value from 0 to 9 when
the LCS code is 'EA' which means delayed call.
fJ
is always O.
Delayed call examples
The last two bytes
Em
are used to provide the time that NCP must wait before
retrying a call when the LCS code is X'EA' (delayed call).
For instance, with the following status codes:
I:lNI4:"':I:II:I,
ID
means 'delayed call' and _ means that NCP must wait 4
minutes before retrying a call.
With the status code:
o
':INIHi!1:.t.J:1
(ID
and _ ) , NCP must wait 12 minutes before retrying a call.
