Description

ISPXGOP_ANSI

If set to 1, ANSI (T1.113 - 1992) operation is
enabled. Typically, for ANSI operation in
accordance with T1.113 bits 0, 1, 2, 3, 4, 5 and
13 need to be set.

Note: for new applications, this option should be
set to 0 and the variant parameter in this
message should be used instead. This option is
retained for backwards compatibility.

ISPXGOP_PRI_BA

If set to 1 message priority in accordance with
T1.111.5 (1992) will be encoded in the MTP-
label SSF bits BA.

ISPXGOP_T34

If set to 1, T34 will be enabled. If set to zero,
T34 will be disabled. T34 is started on receipt of
a message with the segmentation indicator set
(indicating that a second segment is expected) in
an exchange which reassembles segments (i.e.
exchange type 1, 3, 5, or 6). If the timer expires,
an empty message segment (i.e. a SGM
message with no parameters) will be passed to
the user.

ISPXGOP_TRAN_PAM

If set to 1, any Pass-along message received by
ISUP will be transferred as a Pass-along
message (providing that it is received in a valid
call state) and the application will need to handle
the received PAM accordingly. If set to zero, the
message contained within the PAM will be
extracted and processed.

8 - 10

ISPXGOP_COMPAT

• 0 - Blue Book compatibility handling is

performed

(i.e. unrecognized messages and
parameters are handled as specified in Blue
Book)

The following values all relate to Q.764 (03/93)
operation:

• 1 - no compatibility handling is performed (all

unrecognized messages and parameters are
passed to the user application)

• 2 - end node (i.e. exchange type A) message

and parameter compatibility handling will be
performed (passing on unrecognized
information is possible)

• 3 - end node (i.e. exchange type A) message

and parameter compatibility handling will be
performed (passing on unrecognized
information is not possible)

• 4 - transit (i.e. exchange type B) message

and parameter compatibility handling will be
performed

• 5-7 - reserved for future use

11 ISPXGOP_ITU92

Note: For new applications, this option should be
set to 0 and the variant parameter in this
message should be used instead. This option is
retained for backwards compatibility. If set to 1,
this option may be used to set to enable the ITU-
T 1992 extensions.
