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. |

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 |
200mA typ per port (programmable) |
DC supply current, alarm mode programmable range |
150-250mA, with 100mA normal operating current |
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 LNA’s 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 |
+8V to +30V DC |
AISG version |
