Simulcast
Base stations can operate as part of a simulcast channel group. The
transmitters in the channel group are synchronized and transmit
simultaneously on the same frequency. Each transmitter needs a highly
accurate 1PPS pulse and an external frequency reference, so that it can time
transmissions with the required accuracy.
P25 Linking
A pair of base stations can function as linking transceivers and be used to
provide an RF link, for example between a channel group and a base station
at a remote site.
A base station must be appropriately configured using the CSS before it can
function as a linking transceiver. As voting information cannot be carried
over the RF link, signals that the linking transceiver provides to its channel
group must be assigned a source type and given a fixed impairment value.
For details, see the appropriate Tait P25 System Manual and the CSS
Help or manual.
Data Gateway
The data gateway is a function carried out in a Tait P25 base station or P25
console gateway operating in a TaitNet P25 conventional network. It
provides a gateway between P25 radios and a data server. The data gateway
interfaces to P25 radios using the P25 common air interface (CAI) and to a
data server (such as the KMF) using the IP network. The data gateway
function requires the Conventional Packet Data Services feature license and
is enabled in configuration. For details, see the TaitNet P25 Conventional
Networks System Manual and the CSS Help or manual.
