1.2 Network Devices and Numbering Plan8 Getting Started1.2.1 Network ApplicationQSIG Network InterfaceQSIG is a protocol based on ISDN (Q.931) that offers enhanced PBX features in a private network.The QSIG network supports private communications by the TIE line service method. Implementationof VoIP Gateway Cards provides a VoIP interface to employ a QSIG network between PBXs atdifferent locations by using an IP network instead of conventional telephone networks.Types of IP NetworkThe VoIP Gateway Card's quality of performance depends on the type of IP network in use. ManagedIP networks provide better quality of service compared to unmanaged networks such as the Internet,where quality of service is not guaranteed.NoteUnlike an IP-VPN, which is set up over a network provider's own IP network, an Internet VPN isset up over the Internet. As delays and loss in data transmission are likely to occur over theInternet, an Internet VPN is not recommended for use.FirewallA firewall protects the internal networks of an organization against unauthorized penetration fromoutside. When routing a VoIP network through a firewall, some performance degradation may result.If for practical reasons you must route the VoIP network through a firewall, refer to "A1.3 NetworkDevices" for more details.Using the KX-TDA0490 with Other KX-TDA Series VoIP Gateway CardsWhen using the KX-TDA0490 in a network that contains other KX-TDA series VoIP Gateway Cards,keep in mind the following points:1. Making and Receiving CallsCalls can be made and received between the KX-TDA0490 and other KX-TDA series VoIPGateway Cards. However, the KX-TDA0480 requires a special setting to be able to communicatewith the KX-TDA0490 on the network. Refer to "D1 Considerations in Installation" for moredetails.2. Using QSIG ServicesAll QSIG services available with the PBX can be used between the KX-TDA0490 and KX-TDA0484/KX-TDA5480. However, CLIP service is the only available QSIG service between theKX-TDA0490 and KX-TDA0480.Examples of recommended IP networks• Digital Leased Line• IP-VPN (Virtual Private Network)• Frame RelayNot recommended• Internet (including an Internet VPN)
