is present or not in the CONNECT and SETUP call

checked or not in the same messages received by
this basic rate interface (incoming call).
The checking of LLC IE in the incoming calls is
made as described below :
the coding standard must be set to 'CCITT
standardized coding',
the information transfer capability must be set
to 'unrestricted digital information',

set to 'CCITT Recommendation X.25 link
layer' or 'CCITT Recommendation X.25
multilink',
the user information layer 3 protocol must be
set to 'CCITT Recommendation X.25 packet
layer',
the other octets of the LLC IE are not checked,
This object may be set to one of the following
values :
notTransmittedAndNotChecked : the LLC IE is not
present in the outgoing calls and it is
not checked in the incoming calls,
transmittedAndNotChecked : the LLC IE is
present in the outgoing calls and it is
not checked in the incoming calls,
notTransmittedAndChecked : the LLC IE is not
present in the outgoing calls and it is
