Frequently Asked Questions


This list captures answers to some of the common questions. Contact us for anything else.

How does Crux LX work?

Crux LX is a plug-and-play device as it comes pre-configured for most common needs. It just needs to be powered on, and like any other Access Point (AP) or router, its wireless radio or SSID (as described on the box) is available for devices to connect. For it to connect to internet it needs a wired ethernet (RJ45) connector coming from your cable or fiber modem, as you would with any other AP or router. For voice communication, Crux LX acts like a SIP server. To start making calls, you could download any of the SIP client application or softphone application that accepts three inputs: Extension number, Password and IP Address of Crux LX. These three credentials allow a SIP client to register with Crux LX and you are ready to call one another!

How many users can each unit of Crux LX device manage?

Each Crux LX unit can connect up to 250 users though one can configure thousands of extensions on a single unit, if the unit is being used only as an IP-PBX and not as a data router. Browsing needs and patterns can be very different, especially if audio visual content is permissible. The limiting factor however is the expected concurrency. Each Crux LX unit can support up to 20 concurrent conversations. However, you may require multiple Crux LX devices if you expect to connect more than 250 users or require more concurrency. You may also require some additional access points to span the space to connect large number of users who may have a mixed usage (Crux LX as well as regular browsing needs).

Does Crux LX require internet?

Internet is not a requirement for Crux LX when operating autonomously, say for example when Crux LX is being used as a Wireless Intercom. However, when SIP trunks or multiple Crux LX devices are to be inter-networked to connect multiple branch offices, then internet will be required and quality / bandwidth of internet connection will be of importance. It will play a significant role in quality of voice and service delivered by Crux LX for communication over such channels. You may also require some additional networking components based on such use cases.

How much area does the WiFi radio on Crux LX cover?

Crux LX has a circular internal antenna. In our tests, beta trials and few customer deployments, the coverage ranges between 20 – 30 meters spherical radius. However, wireless signal can vary drastically based on construction and use of glass and metal. Typically scaling beyond one floor above or below, or 10,000 square feet of horizontal space will require additional Wireless Repeaters or Access Points. Crux LX pairs well with D-Link DIR-816 which is an inexpensive router (retails for $40-50) that works well as a repeater that provides good ground coverage and well suited for this use.
