The Omnitronics IPR Series of Radio over IP (RoIP) interfaces
are designed to merge the power and fl exibility of IP with our
customers’ analog radio equipment and networks. This greatly
increases communication reach and offers many benefi ts
including interoperability, scalability, low cost of ownership and
ease of implementation. The IPR Series enables you to create
fl exible and powerful radio networks with convenient operator
access.
Three key products make up the IPR Series interface family:
The IPR100 is a single analog audio channel to IP interface. It is
equipped with a local Omnitronics 960 Series handset/console
interface or a standard 4-Wire E&M analog interface.
The IPR400 is a four analog audio channel to IP interface
providing the added ability to cross band and bridge channels
in a myriad of combinations, in the convenience of a single
enclosure.
The IPR110 Plus – Advanced VoIP and SIP Gateway, includes
the IPR100 feature set with the integration of Session Initiation
Protocol (SIP) allowing customers to combine their telephony
PBX systems with their radio networks.
All devices use data messaging to transport signalling schemes
such as SELCAL, ANI, DTMF and CTCSS overcoming the
problems normally associated with losses from compression
algorithms and lost packets. Voice Activity Detection (VAD)
enables the IPR Series to work with HF radios where a Carrier
Detect input is unavailable and Silence Suppression optimizes
the use of available IP bandwidth and is particularly benefi cial in
satellite and 3G-cellular applications.
The 4-Wire E&M analog interface is provided on RJ45 connectors
conforming to International Standards. Each port provides
balanced two wire 600 ohm transformer coupled TX and RX
audio interfacing, isolating the IPR from the radio and virtually
eliminating ground noise and induced signal interference.
The IPR Series interface family can be confi gured within LAN,
VPN or WAN environments using a standard web browser. The
devices support both DES and AES encryption which can be
enabled for all voice and data transmissions. Restrictions do
apply regarding export of AES encryption and Export Applications
would apply for AES enabled IPR Series for overseas sales.
