eSpace U1980 Single-Site Centralized Networking


eSpace U1980 supports centralized networking, which is also applicable to large- and medium-sized enterprises with several branches. U1980 can be deployed as an IP PBX at headquarters or can be used as a remote survival gateway in big branches.


eSpace U1980 is deployed at headquarters, and connects to carrier' networks like PSTN through E1 and T1 interfaces. If necessary, application and management servers can also be deployed. Users at headquarters can adopt various types of terminals like analog phones, IP phones and soft clients to enjoy the communication services.


For the large and medium-sized branch, one independent IP PBX eSpace U1900 can be deployed to implement incoming and outgoing call with PSTN locally, as well as local regeneration. All the users in the branch register to the U1980 in the HQ in normal situation, and share the services provided by it. When the U1980 in the HQ is down, or the network between branch and HQ is interrupted, then the users will register to the local U1900 in the branch and implement the basic call.


For the small-sized branch, IAD is suggested to be deployed. IAD supports local switch for analog phones.
