Csináltam egy kis tesztet az ISDN PRI trunk hívásirány korlátozásával kapcsolatban. Hát igen, ez kicsit beteges teszt…bridge loop, routing loop, call setup loop… )

A teszt rendszer:

 

1.      trunk-group erőforrás menedzsment.

 

A feature segítségével lehetséges korlátozni a hívástípusokat az ISDN PRI controller interfészen. További információk erről itt.

A konfiguráció:

 

trunk group  call_out_backup

 max-calls voice 25 direction in

 max-calls voice 30 direction out

 

controller E1 0/3/0

 pri-group timeslots 1-31

 trunk-group call_out_backup timeslots 1-31

2.      A teszt rendszer:

 

Tesztünkben hívásfelépítés kört hoztunk létre. Olyan dial-peereket konfiguráltunk, hogy az egyik routerről indított hívás ISDN-en, majd onnét vissza H.323-on továbbítódott a kezdeményező router irányába. Az eredmény tehát az lett, hogy hívásfelépítés kezdeményezésekor az összes ISDN PRI csatornát elhasználtuk, majd végül megszakadt a hívásfelépítés. A teszttel bizonyítani tudjuk, hogy a trunk-group erőforrás menedzsment valóban használható arra, hogy az ISDN PRI csatornán 5db csatornát mindig fenntartsunk kimenő hívások céljából, a bejövőekkel szemben.

3.      A Teszt

Miután a teszt rendszert felépítettük, az ISDN-PRI-Slave routeren csim start 1111 paranccsal hívásfelépítés kört hoztunk létre. A routeren az ISDN Q931 üzeneteket debuggolva, a következőt láttuk:

A csim parancs kiadása után az ISDN PRI trunk linken elkezdődött a B csatornák lefoglalása. A 31-es csatornától visszafelé, az 5-ös csatornához érve, az ISDN-PRI-Master router már elutasította a csatorna foglalást, ugyanis ott a max bejövő hívások száma 25-re van korlátozva.
