3.4.2Router Connected to PBX in ISDN PRI Mode

I.Networking requirement

The telephones in Beijing and Shenzhen communicate with each other directly via IP network using routers with voice function. The FXS (POTS) interface of Beijing router is connected to the telephone directly and is connected to PBX exchange through E1 voice port. The Shenzhen router is connected to PBX exchange only through E1 voice port. The routers in both places are connected to the exchange by adopting ISDN PRI interface DSS1 subscriber signaling and adopts single stage dialing mode.

II. Networking diagram

The networking diagram is similar to VC-3-2, except that ISDN PRI interface DSS1 subscriber signaling is adopted between PBX and the router.

III.Configuration procedure

1)Parameter configuration of the Beijing-side router ! Configure ISDN PRI group

Quidway(config)# controller e1 0 Quidway(config-if-E1-0)# pri-group

! Create POTS dial-peer on FXS interface (telephone number 010-1003) Quidway(config)# dial-peer voice 1003 pots

!Configure the destination pattern of the POTS dial-peer on FXS interface (tel: 010- 1003)

Quidway(config-peer-pots1003)# destination-pattern 0101003

!Configure the POTS peer on FXS interface to correspond with the logical port (telephone number 010-1003)

Quidway(config-peer-pots1003)# port 0

!Create the POTS dial-peer on ISDN PRI interface (telephone number 010-1001) Quidway(config)# dial-peer voice 1001 pots

!Configure the destination pattern of POTS dial-peer on ISDN PRI interface (tel: 010- 1001)

Quidway(config-peer-pots1001)# destination-pattern 0101001

!Configure the POTS peer on ISDN PRI interface to correspond with logical port (tel: 010-1001)

Quidway(config-peer-pots1001)# port 0:15

! Create VoIP dail-peer
