An enterprise. the interconnection between PBX user and NGN can be implemented. when one of the networks is busy or out of service. as shown in the right part of Figure 4-3. so as to implement the “one set with two numbers” function. The IAD132E(T) in right part can call the subscribers in the PSTN through the IAD132E(T) in left part. In Figure 4-3. In this way. or PSTN calls. 4-2 . In this way. A subscriber has two numbers for the two networks. As shown in Figure 4-3. configure the IAD132E(T) as to provide AT0 call. the IAD132E(T) allows coexistence of circuit-switched phones and packet-switched phones.System Description U-SYS IAD132E(T) Integrated Access Device Chapter 4 Networking Applications to the output pins 1. 3 IP Centrex Networking This networking provides IP Centrex solution for large or medium-sized enterprises.System Description U-SYS IAD132E(T) Integrated Access Device Chapter 4 Networking Applications NGN NMS SoftSwitch iOSS App server IP network IADMS PSTN LSW PBX LSW FXO FXO IAD132E(T) IAD132E(T) FXS FXS Figure 4-3 Networking with current PSTN/PBX The Foreign eXchange Subscriber (FXS) port usually connects with ordinary telephone set or fax machine on the subscriber side. In this application. you need to set the convergence ratio to 16:16. in order to provide calling signals like the ringing tone and dialing tone. The SoftSwitch defines the headquarters and the branches as a basic subscriber group. 4. the convergence ratio between the FXO port and the FXS port can be 4:32. They can enjoy the basic services and new services of IP Centrex. 4:16 or 16:16. the FXS ports and FXO ports work together so that the POTS subscribers can access the PSTN. IP Centrex can be used for the communication among the headquarters and branches in different geographical locations. Subscribers in this group can be both IP phone subscribers and PBX subscribers.
