l1_resource_id
The logical identity of the link set, in the range 0 to one less than the number of link
sets supported, The linkset_id is used in other commands for reference
data_rate
Used for setting the link operation. The following table shows the permitted values and
their meaning.
Value

0
64 kbits/s
1
56 kbits/s
2
48 kbits/s
link_source
Configure the signaling source.
Set to 0 for DSI SS7MD Board.
link_stream
Signaling stream. This parameter is the physical 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. The value
ranges for link_timeslot are 1 to 24 for a T1/J1 interface and 1 to 31 for an E1
interface.
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 onboard 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. This option is provided for backwards compatibility only.
— Bit 4 – This bit is used to select the size of the sequence number field. This is
necessary in addition to appropriate configuration of the MTP2 layer. The bit is only
applicable for HSL operation and should otherwise be set to zero. For HSL operation
the bit should be set to 0 for 7-bit sequence numbers or set to 1 for 12-bit sequence
numbers.
— Bit 6 – This bit is used to configure the layer 1 functionality to select between LSL
and HSL operation to ensure the appropriate error rate monitoring mechanism is
selected. This is necessary in addition to appropriate configuration of the MTP2 layer.
The value should be set to 0 for LSL operation and 1 for HSL operation.
— All Other Bits - Must be set to 0.
