P25 Phase 1 FDMA, or 6.25kHz equivalent P25 Phase 2 TDMA

An IP connected transceiver in analog conventional simulcast networks
The TN9275 P25 analog gateway provides a subset of P25 conventional
operation when compared to the TB9400 base station. It provides all of the
functions of a channel group master with analog, P25 and dual
conventional operation, but it does not have an RF transceiver.
Physically, the gateway module is similar to a reciter without the RF
transmit and receive connectors.
The gateway and base station share the same firmware. The first firmware
release supporting the TN9275 operation is 3.45.00
In this manual, where it says “base station” or “reciter”, it should also be
understood to generally refer to the TN9275 gateway, with the exception of
any RF and transceiver functions.
