power supply and alarm (current window alarm mode, default)
DC supply voltage +9 to +30V DC
DC supply Each BTS port powered individually at 100mA minimum
DC supply current, normal mode 100mA typ per port
DC supply current, alarm mode programmable
DC supply current, alarm mode programmable range 150 - 300mA
aisg mode of operation (auto selected on valid aisg 2.0 frames)
AISG signals can be applied to either BTS port. The TMA unit switches to AISG mode when valid frames are detected on one of the ports. The TMA is DC powered from the BTS port supplying the AISG frames or from both ports if both have DC voltage.
AISG version 2.0, with current alarm window backup
Supply current, AISG mode 210mA typical @ 9V
AISG connector, current rating < 4A peak, 2 Amp continuous, pin 6
Field firmware upgradable Yes
