E1 voice DSS1 signaling configuration example
Network requirements
As shown in Figure 24, Telephones in City A and City B communicate with each other through voice routers (Router A and Router B) across an IP network.
In City A, Router is connected to a PBX through an E1 subscriber line, and to the telephone at 0101003 through an FXS voice subscriber line.
In City B, Router B is connected only to a PBX through an E1 subscriber line.
The two routers communicate with their respective PBX by exchanging DSS1 user signaling through an ISDN interface. One-stage dialing mode is configured on the two routers.
