DSI SS7MD Programmer’s Manual Issue 3
Configure the LSL timeslot rate:
•
l1_resource_id
Layer 1 (logical) resource identifier.
•
data_rate
Used for setting the link operation. The following table shows the permitted values and their meaning.
•
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:
— For a T1 interface: 1 to 24.
— For an E1 interface: 1 to 31.
— For a J1 interface: 1 to 24.
•
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 .
— Bit 4 - HSL operation. Set to 0 for 7-bit sequence numbers. Set to 1 for 12-bit sequence numbers.
— Bit 6 - HSL operation. Set to 0 for LSL SS7. Set to 1 for HSL SS7.
— All Other Bits - Must be set to 0.
•
timeslot_mask
Signaling timeslot mask. This field is used to configure HSL links. Bits 0 to 31 of the mask correspond to
timeslots 0 to 31 of the signaling stream identified by the
link_stream parameter. The recommended
bits masks values are:
Value Data Rate
0 64 kbits/s
1 56 kbits/s
2 48 kbits/s
Value Description
0xfffffffe structured E1 HSL, 31 slots (1 to 31)
0x01fffffe structured T1 HSL, 24 slots (1 to 24)
0xfffefffe structured E1 HSL, 30 slots (1 to 15,17 to 31)
