DSI SS7MD Programmer’s Manual Issue 3
QSAAL_MSG_TIMERS messages may be issued to the Q.SAAL module to modify timer configuration
parameters however; these messages do not affect Q.SAAL operation (that is, the power up sequence is not
re-executed, but the parameters are modified).
•
link_id
Identifier for this link.
Note:
This identifier is required to be unique only within the context of the board.
•
Options
•
upper_link_id
Upper layer link identifier
•
cell_stream
The cell stream to which we wish to attach the link
•
upper_mod_id
The recipient module ID for the link.
•
VPI
The VPI of the AAL5 stream to use. The VPI must be viable in the mask configured in the
ATM_MSG_CONFIG message.
•
VCI
The VCI of the AAL5 stream to use. The VCI value must be viable in the mask specified in the
ATM_MSG_CONFIG message. Note: 0, 3 and 4 are reserved
•
mgmt_id
Id of Management module for status updates
•
lower_mod_id
The module ID for the lower level ATM module
•
max_SIF_len
The maximum length of signaling Information Field (SIF) to support. This should be set to either 62 or
272 in accordance with Q.703.
•
cong_onset
The congestion onset threshold for use with the single congestion threshold mode of operation.
Congestion is indicated when the total number of messages in the transmit and retransmit buffers rises
to this value.
•
cong_abate
The congestion abatement threshold for use with the single congestion threshold mode of operation. Link
uncongested is indicated when the total number of messages in the transmit and retransmit buffers falls
below this value.
•
cong_discard
The congestion discard threshold for use with the single message priority mode of operation. When the
combined number of messages in the transmit and retransmit buffers reaches this threshold, further
messages are discarded. The congestion discard threshold cannot be set to a value greater than 4095.
•
maxcc
Number of retransmissions on connection establishment and release request.
•
maxpd
Maximum number of SD PDUs sent between polls.
•
n1
Number of proving PDUs sent during proving.
Bit
Options
1
Set to 1 to enable multiple congestion states and multiple message priority
option. This option should always be enabled when running in ANSI mode.
Others
Reserved for future use and must be set to 0.
