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

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.

 

 

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.
