E1 voice DSS1 signaling configuration example

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.

1. Configure Router A:

   # Configure the IP address 1.1.1.1/24 for the interface Ethernet 2/1.

   <RouterA> system-view
   [RouterA] interface ethernet 2/1
   [RouterA-Ethernet2/1] ip address 1.1.1.1 255.255.255.0
   [RouterA-Ethernet2/1] quit
   

   # Create an ISDN PRI group on interface E1 1/1.

   [RouterA] system-view
   [RouterA] controller e1 1/1
   [RouterA-E1 1/1] pri-set
   

   # Create a POTS voice entity for the FXS interface.
