Method utilizing passive optical network (PON) system access terminal to achieve internet protocol (IP) voice service call simulation
ActiveCN103200469AReduce maintenance investmentMultiplex system selection arrangementsSupervisory/monitoring/testing arrangementsTelecommunicationsSimulation testing
The invention discloses a method utilizing a passive optical network (PON) system access terminal to achieve internet protocol (IP) voice service call simulation. The method includes the steps of outgoing call simulation testing and incoming call simulation testing. In the outgoing call testing, an outgoing call simulation state machine simulates to automatically complete all operations of a calling party. After a call is put through, an operator can check whether dialing and calling can be normally carried out through a port of the calling party according to the condition whether sound of the calling party can be heard. In the incoming call simulation testing, an incoming call simulation state machine simulates to automatically complete all operations of a called party responding to the calling party. The operator can check whether ringing and calling can be normally carried out through a port of the called party according to the condition whether sound of the called party can be heard. The method can be adopted to automatically complete detection and diagnosis of voice links, and consequently the common staff can achieve maintenance of IP voice services of the access terminal in a local side management system, and the maintenance cost of service suppliers can be reduced.
