DSI SS7MD Programmer’s Manual Issue 3
— Bit 12 is used to select 12- or 7-bit sequence numbers for HSL only. This bit should be set for 12-bit
sequence numbers, clear otherwise.
— Bits 13 and 14 reserved. Set to 0.
— Bit 15 is set to 1 to disable the link. This bit should be set to 0 to enable normal link operation.
— All other bits are reserved for future use and should be set to 0.
•
<data_rate>
An optional parameter to specify link parameters, required for HSL or ATM operation. The valid values
are:
MTP HSL/LSL Link Parameters
•
<board_id>
The logical identity of the board in the range 0 to one less than the number of boards supported.
•
<blink>
The index of the signaling link. It must be in the range 0 to one less than the number of signaling links
licensed on the board.
•
<stream>
When the <timeslot> parameter is set to a non-zero value, the <stream> parameter is the logical
identity of the T1/E1/J1 LIU (liu_id) containing the signaling link. It should be in the range 0 to one less
than the number of LIUs.
•
<timeslot>
The timeslot used for signaling in the range 0 to 31. The valid ranges are:
— For a T1 interface: 1 to 24.
— For an E1 interface: 1 to 31.
— For a J1 interface: 1 to 24.
For HSL operation:
— 0xff - Data rate is set using the optional data rate parameter, if not present data rate defaults based
on LIU type (T1/E1).
— All other values are reserved for future use.
ATM Link Parameters
•
< board_id>
The logical identity of the board in the range from 0 to one less than the number of boards supported.
This should be the same value as used in the ATM_STREAM command. If the value selected is different,
then the configuration will be rejected.
•
<blink>
The index of the signaling link. It must be in the range 0 to one less than the number of signaling links
licensed on the board.
•
<atm_stream>
This defines the logical id of the cell stream over which the link runs. It must be in the range 0 to one
less than the combined number of ATM Cell Streams supported by all the SS7MD boards in the system.
•
<vpi-vci >
This is a compound parameter that identifies the VPI and VCI of the ATM link. It is represented in the
form vpi-vci where:
Value Description
TDM single timeslot SS7 LSL (default)
E1_FRAMED HSL structured 31 slot E1 operation
T1_FRAMED HSL structured 24 slot T1/J1 operation
E1_PCM
HSL structured 30 slot E1 operation (where
timeslots 0 and 16 are not used for signaling)
ATM The command follows the syntax for ATM links
