If you wish to budget for Internet access costs you will need to think about whether you prefer time or data based charging. XTRA Velocity currently does not support static IP addresses, which are necessary if you wish to use your own email server. The JetStream modem does not function as a router, which means that it cannot provide some features such as controlling which users on the LAN can have Internet access, and other security features. JetStream is currently not available in all Telecom exchange areas but is being rolled out nationally. JetStream is also subject to some technical limitations that may mean it is not available to you even if your premises are on an JetStream-enabled Telecom exchange.
Full details are available on the web site.
Telecom's JetStream service is based on data charges, whereas Telecom and XTRA ISDN pricing is time based. It is therefore difficult to compare the two. The Telecom accredited JetStream installer will do all this for you onsite, however, if you are connecting a LAN to XTRA Velocity you may need an IT specialist to assist in the installation.
