Grzegorz,
I'm trying to write a patch for chan_ss7 to send BLO from the CLI. While
browsing the source code I came across the option grs you can define in
your linkset configuration. I think that if you set this to no a block
from the command line will use BLO instead of CGB.
config.c:
438 if ((strcasecmp(v->value, "0") == 0) ||
(strcasecmp(v->value, "no") == 0)) {
439 linkset->grs = 0;
440 }
in l4isup.c:
4255 static int do_group_circuit_block_unblock(struct linkset* linkset,
int firstcic, unsigned long cgb_mask, int sup_type_ind, int
own_cics_only, int do_timers, int do_block) {
Which decides the sending of BLO vs CGB:
4267 if (linkset->grs) {
If grs = on (default) it will send CGB,
otherwise:
4310 else {
4311 for (p = 0; p < 32; p++) {
4312 param[0]++;
4313 if (cgb_mask & (1<<p)) {
4314 pvt = linkset->cic_list[firstcic+p];
4315 if (pvt) {
4316 struct link* link = pvt->link;
4317 if ((1<<(firstcic - link->first_cic + p)) &
link->schannel.mask)
4318 continue;
4319 }
4320 if (own_cics_only)
4321 if (!pvt || !pvt->equipped)
4322 continue;
4323
4324 if (do_block) {
4325 isup_send_blk(pvt);
4326 if (do_timers)
4327 t12_start(pvt);
4328
4329 } else {
4330 isup_send_ubl(pvt);
4331 if (do_timers)
4332 t14_start(pvt);
4333 }
4334 }
4335 }
4336 }
I hope this is useful for you untill I write a patch to do both methods
from the CLI.
Kind regards,
Matthias van der Vlies
