power supply and alarm (current window alarm mode, default)
Current window alarm mode (CWA) is the default TMA operating mode and can be configured to specific customer requirements. The generic personality (F00Vx) is configured so that both channels are independently powered and monitored via the respective BTS port. The BTS port sinks additional current to indicate an alarm state in its uplink path. Normal operating and alarm current values are configured independently and are alterable via a field-loadable personality file.
DC supply voltage7.5 to 30V DC, case is DC ground
DC supply voltage via BTS-RF cableEach BTS port powered individually (programmable)
DC supply current, normal mode150 ± 20mA per port
DC supply current, alarm mode programmable range220 ± 20mA per port
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to either BTS1 or BTS2 port. The TMA unit switches to AISG mode when valid frames are detected on one of the BTS ports. Both LNAs take DC power from the port with AISG frames or, if DC is present on both ports, both channels supply equal power to the TMA.
DC supply voltage+7.5V to +30V DC

autosensing function on ant 1 aisgout port (tma2089f02v3 only)
When a valid AISG signal is applied to either of its BTS ports, the TMA2089F02V3-1 enters AISG mode and applies DC/AISG to the ANT 1 AISGOUT port. If a low resistance is detected, DC/AISG is subsequently disconnected from the ANT 1 AISGOUT port. In CWA mode, the autosensing switch is open and no DC is passed to the ANT 1 AISGOUT port.
