Section 8 Non-Primitive Interface

sccp_id
Reserved for future use, this should always be set to zero.
maint_id
The module_id of the module for which all protocol maintenance indications
are sent. If this field is set to zero or the length of the parameter area is less
than 26 bytes (for backwards compatibility with previous releases of
software) then ISUP will use the supplied in the per-module configuration
message and force maint_inst to zero.
maint_inst
The instance number used in messages sent to the maint_id module.
sio
The value to be used for the Service Indicator Octet in messages issued to
the MTP for the group being configured, instead of the sio provided in the
module configuration message. If the length of the parameter area is less
than 64 bytes (for backwards compatibility with previous releases of
software) then ISUP will use the sio supplied in the per-module configuration
message.
tim_tab_id
The id of the timer table to be used for circuits in this group. If the length of
the parameter area is less than 31 bytes (for backwards compatibility with
previous releases of software) then ISUP will use timer table 0. Up to four
timer tables (id 0 to 3) are supported by the module.
ext_1_options
Further run-time options assigned according to the following table:
Bit Number Mnemonic Description
0 ISPX1GOP_ADD_ST If set to 1, messages sent to the user will have
an ST digit added to the called party number.
Note: this option may also be used for ANSI
ISUP, which does not allow use of the ST digit,
and means that the format of the Setup
indication is the same regardless of whether
the call is received over ANSI or ITU ISUP.
1 ISPX1GOP_16PC If set to 1, circuit groups are configured to use
16-bit point codes. Note that currently all
groups must use the same point code size.
This circuit group option is intended to be used
in conjunction with the ISPF_PC_SIZE module
option.
2 ISPX1GOP_T33EXP_NOREL If set to 1, when timer T33 expires, the call is
NOT released.
3 ISPX1GOP_USR_SVC_PRV If set to 1, user-to-user service does not have
to be requested to use user-to-user information
parameter.
