FIXED STATION ETHERNET INTERFACE OPERATION
The MT-4R, MT-4D Repeater and MT-4D Base modules may be confi gured to operate as a digital
Ethernet controlled base station using the UIC-4-00 Universal Interface Card (UIC). The UIC card
provides a direct digital interface from the receiver and transmitter to an IP network via an RJ45
Ethernet connector. The UIC allows the Ethernet interface to and from both MT-3 and MT-4 receiver
and transmitter modules. This Ethernet interface allows digital signals (such as NAC, TGID, Source ID)
to be passed through the network to and from web based applications and digital consoles. Figure 3-6
shows the UIC card used in the fi xed station Ethernet interface system.

Several releases of the UIC card fi rmware are planned. The fi rst two releases are outlined below:
Release 1.0
The UIC card uses PCM based audio and a proprietary signaling format that Daniels Electronics Ltd.
makes available to any console / VoIP manufacturers that may wish to be compatible with Daniels base
stations. Daniels is currently working with Catalyst Communications Technologies, Twisted Pair
Solutions, Avtec, and Pantel in support of this open interface.
Features:
- Receive / Transmit baseband PCM audio via UDP protocol over Ethernet
- Flash upgradable fi rmware
- Channel and Bank control
- Ability to identify incoming P25 NAC
Release 2.0 (Available First Quarter 2007)
The UIC card is TIA-102.BAHA Conventional Fixed Station Interface compliant. Daniels is currently
working with Telex/Vega Signalling Products and Zetron in support of this P25 interface.
Features:
- Receive / Transmit IMBE vocoded audio via RTP protocol over Ethernet
- Encryption capability from the console (end-to-end encryption)
- Multiple console support
- Ability to identify incoming P25 Unit (Source) ID, Talk Group ID and Emergency bit
