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 (F00V1) 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, contact Kaelus for more information. |
| DC supply voltage |
8.5V to 30V DC |
| DC supply voltage via BTS-RF cable |
Each BTS port powered individually (programmable) |
| DC supply current, normal mode |
100mA typical, 120mA maximum (programmable with two BTS ports powered) |
| DC supply current, alarm mode |
180mA typical |
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 unit is DC powered only from the BTS port supplying the AISG frames. |
| DC supply voltage |
+8.5V to +30V DC |
| AISG version |
