Features Networking As your company's requirements grow, OpenCom X320 can be networked with other communications systems via permanent ISDN lines ("Q.SIG") or via Internet connections ("Q.SIG-IP"), connecting distant locations and branch offices in a single, comprehensive telephone network. OpenCom X320 can for example, operate as a sub-system or a DECT server via the Q.SIG network. This type of networking is described in the chapter on PBX Networking starting on page 129. DECT Networks OpenCom X320 supports the setting up of a DECT network, enabling mobile office communications. For larger offices, using several DECT stations (RFP, Radio Fixed Parts) can expand wireless network coverage and provide a transparent handover between the RFPs while maintaining the telephone connection. Handsets as system terminals with all the system telephone features are available for DECT telephony and handsets using GAP and CAP standards are also supported. The handover between the RFPs also functions with handsets using the GAP standard. Up to 4 calls can be made simultaneously via an RPF, and up to 8 calls can be made simultaneously if an RFP is connected via 2 Upn connections. The DECT network can also be operated using VoIP (see DECToverIP® starting on page 11). Voice over IP (VoIP) OpenCom X320 supports the connection of VoIP terminals, enabling the company's existing internal network infrastructure (LAN with 100 MBit/s) to be used for telephony as well. Corded system terminals of the OpenPhone 73 IP, OpenPhone 75 IP and VoIP system telephones OpenPhone 63 IP and OpenPhone 65 IP types are available for this purpose. These devices have the same functionality and support the same features as the non IP-enabled system terminals. The eight gateway channels of an installable Media Gateway card are automatically switched on for telephone calls between IP terminals and ordinary terminals, for data compression, for the generation of DTMF and dial tones and for echo suppression. It is also possible to use a limited range of VoIP functions without additional Media Gateway cards. The system software provides up to 32 uncompressed VoIP gateway channels without echo compensation. For users wanting to use PC-supported telephony, IP system terminals are available as separate licensable software versions ("Softphone"). You will find 10
