Set desired IRLP parameters to be negotiated with the peer at the start of the next data call.
Note that these desired parameters are reset to hardcoded defaults at the end of a data call, so
this command should be issued while a call is not in progress.
<ver> specifies the desired IRLP version and can take the following values:
0
Default IRLP version (N0)
<k1> represents the maximum number of sequentially numbered I frames that may be
outstanding at any given time at downlink direction (IWF->A3LA-RS) and can take the following
values:
1-105. Default is 105.
<k2> represents the maximum number of sequentially numbered I frames that may be
outstanding at any given time at uplink direction (A3LA-RS->IWF) and can take the following
values:
1-105. Default is 105.
<t1> is used to supervise the acknowledgment of transmitted unnumbered frames. The values
are defined to be the earliest instant to enter the recovery procedure and can take on the
following values:
27-255 (in 50-ms unit). Default is 30.
<n2> is used to represent the maximum number of re-transmission attempts of a frame (e.g.
I,S,N,U frame) and can take on the following values:
1-255. Default is 15.
<t2> is used to indicate the amount of time available within which the acknowledging frame
must be transmitted and can take on the following values:
1-255 (in 10-ms unit). Default is 10.
<r1> is used to represent the maximum number of S frames that are used to acknowledge I
frames at downlink direction (IWF->A3LA-RS) and can take on the following values:
1-10. Default is 10.
<r2> is used to represent the maximum number of S frames that are used to acknowledge I
frames at uplink direction (A3LA-RS->IWF) and can take on the following values:
1-10. Default is 10.
<t4> is used to supervise the re-sequencing of misordered frames. The values are defined to be
the earliest instant to consider a tardy frame as lost. It can take on the following values:
20-255 (in 10-ms unit). Default is 25.
<mode> is used to indicate the mode of operation and can take on the following values:
0
unacknowledged mode of operation
1
acknowledged mode of operation (default)
