link_stream
Signaling stream. This parameter is only valid when link_source is set to 0. It is the
logical identity of the T1/E1/J1 line interface containing the signaling link. The value
range is 0 to one less than the number of LIUs.
link_timeslot
Signaling timeslot. This field is used to configure conventional SS7 links when
link_source is set to 0. Otherwise it must be set to 0. The value ranges for
link_timeslot are:
— For an E1 interface: 1 to 31.
— For a T1 interface: 1 to 24.
link_ct_channel_tx
CT Bus channel from transmission timeslot. This parameter is only valid when
link_source is set to 1. Set to 0 when link_source is not set to 1.
link_ct_channel_rx
CT Bus channel from reception timeslot. This parameter is only valid when
link_source is set to 1. Set to 0 when link_source is not set to 1.
options
A 32-bit value containing run-time options as follows:
— Bit 0 - Set to 1 to disable automatic FISU generation. This is normally
required for Japanese MTP operation only.
— Bit 1 - Set to 1 to enable on-board time stamping on monitored links.
Setting this bit changes the MSG type of the monitor message from
API_MSG_RX_IND to API_MSG_RX_INDT.
— Bit 4 - HSL mode. Set to 0 for 7-bit sequence numbers. Set to 1 for 12-
bit sequence numbers.
— Bit 6 - HSL mode. Set to 0 for conventional SS7 operation. Set to 1 for
HSL operation.
— All Other Bits - Set to 0.
timeslot_mask
Signaling timeslot mask. This field is used to configure HSL links when link_source is
set to 0. Otherwise, it must be set to 0. Bits 0 to 31 of the mask correspond to
timeslots 0 to 31 of the signaling stream identified by the link_stream parameter. The
recommend bits masks values are:
