2.2 Components of SME VoIP System
RTX SME VoIP system is made up of (but not limited to) the following components:
• At least one RTX Base station is connected over an IP network and using DECT as air-core interface.
• RTX IP DECT wireless Handset.
• RTX SME VoIP Configuration Interface; is a management interface for SME VoIP Wireless Solution. It runs on all IP
DECT Base stations. Each Base station has its own unique settings.
RTX Base stations
The Base station converts IP protocol to DECT protocol and transmits the traffic to and from the end-nodes (i.e.
wireless handsets) over a channel. It has 12 available channels.
In a multi-cell setup, each Base station has:
• 8 channels have associated DSP resources for media streams.
• The remaining 4 channels are reserved for control signaling between IP Base stations and the SIP/DECT end nodes
(or phones).
Base stations are grouped into clusters. Within each Cluster, Base stations are synchronized to enable a seamless
handover when a user moves from one Base station coverage to another. For synchronization purposes, it is not
necessary for Base stations to communicate directly with each other in the system. E.g. a Base station may only need
to communicate with the next in the chain. It is advisable for a Base station to identify more than one Base station to
guarantee synchronization in the situation that one of the Base stations fails.
The 4 control signaling channels are used to carry bearer signals that enable a handset to initiate a handover process.
SME VoIP Administration Server/Software
This server is referred to as SME VoIP Configuration Interface.
The SME VoIP Configuration Interface is a web-based administration page used for configuration and programming of
the Base station and relevant network end-nodes. E.g. handsets can be registered or de-registered from the system
using this interface.
The configuration interface can be used as a setup tool for software or firmware download to Base stations, repeaters
and handsets. Further, it is used to check relevant system logs that can be useful to the administrator. These logs can
be used to troubleshoot the system when the system faces unforeseen operational issues.
The web-based administration page is compatible with the following browsers:
 Chrome 68+
 Edge 42+
 Firefox 61+
 Safari 11.1.2+
RTX Wireless Handset
The handset is a lightweight, ergonomically, and portable unit compatible with Wideband Audio (G.722), DECT, GAP
standard, CAT-iq audio compliant.
The handset includes color display with graphical user interface. It can also provide the subscriber with most of the
features available for a wired phone, in addition to its roaming and handover capabilities. Refer to the relevant
handset manuals for full details handset features.
