l3_flags - level 3 flags
Bit 0 is set to 1 to disable the level 3 discrimination function (allowing the
signalling point to receive all messages irrespective of the destination point
code contained in the message) or 0 to allow the discrimination function to
function normally.
Bit 1 is set to 1 to disable sub-service field (SSF) discrimination. If this bit is set
to 0, received MSUs whose ssf value does not match the configured ssf value
will be discarded.
Bit 8 is set to 1 to select ANSI operation or zero for ITU-T operation.
Bit 9 is set to 1 to select ANSI style 24 bit point codes in the MTP routing label
or zero to select ITU-T style 14 bit point codes. This bit should always be set to
one when ANSI operation is selected.
Bit 10 should be set to 1 for ANSI operation or zero for ITU-T operation.
Bit 11 should be set to 1 for ANSI operation or zero for ITU-T operation.
All other bits are reserved for future use and should be set to zero.
NOTE: For correct ANSI operation bits 8, 9, 10 and 11 must all be set to 1.
pc - point code
The point code of this signalling point coded in pure binary representation.
Should be in the range 0 to 16383 for 14 bit point code operation or 0 to
16777215 for 24 bit point code operation.
ssf - sub-service field
The value to be used in the sub-service field of all messages generated by level
3. Should be in the range 0 to 15. For correct ANSI operation the 2 least
significant bits must always be set to 1.
up_enable - User Part Enable
A 16 bit mask used to enable or disable reception of messages on a per user
part basis. If bit N is set to 1 then messages for user part N will be received by
the signalling point.
For example to enable the TUP User Part (Service indicator = 4) set the
up_enable field to 0x0010, For ISUP (Service Indicator = 5) set the up_enable
field to 0x0020. To use both TUP and ISUP set up_enable to 0x0030.
