Features The routing table for X.31packet data is set in the configurator under PBX Configuration: X.31. Additional information can be found in the Configurator Online Help files. Further Telephony Features The installed memory card enables you to operate a digital voice memory and voice information system. For more information, please refer to the user guides "OpenVoice" and "OpenAttendant". You can optimize your telephone communications by using team functions and call-queuing function. The separate licensable "OpenCount" Web application enables you to record, store and analyse telephone connections using configurable filters. You will find more information on this topic in the Online Help of the Web console. Internet access It is possible to connect a complete company network (LAN, Local Area Network) with the OpenCom X320. All work station computers within the LAN can then access the Internet via the OpenCom X320. If Internet access is already available from an Internet Service Provider, this can also be configured in the OpenCom X320. The OpenCom X320 provides the IP configuration required for Internet access. A DHCP server and a DNS server are integrated into the OpenCom X320 and these handle the administration of IP addresses and name resolution for the client computers. The OpenCom X320 provides Internet access for all connected PCs through a common IP address. Only this address is externally visible in the Internet. Network Address Translation (NAT) translates the local IP addresses of the client computers to the IP address of the OpenCom X320. This means that the workplace computers in the LAN cannot be directly reached from the outside (i.e. from the Internet) and are thus protected from direct attack from the Internet. The LAN is additionally protected by the OpenCom X320 filter lists, which can be individually configured (Firewall function). Note: We recommend you read the explanations in Useful Information on Internet Access starting on page 88. E-Mail An e-mail function, which can use the POP3, APOP or IMAP4 protocols to check the Internet Service Provider for incoming mail, is integrated into the OpenCom X320. Mail account retrieval can be configured for each member of staff 12
