POWER SUPPLY AND ALARM (CURRENT WINDOW ALARM MODE, DEFAULT)
| CWA is the default TMA operating mode and can be configured to specific customer requirements. The TMA is configured so that each BTS port is individually powered and monitored. Each 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 |
+7.5V to +30V DC, case is DC ground |
| DC supply |
Through BTS connector |
| DC supply current, normal mode |
100 ± 20mA per port |
| DC supply current, alarm mode |
200 ± 30mA per port |
POWER CONSUMPTION
| Normal operation |
0.85W @ 7.5V, 3W @ 30V typical |
| Alarm mode |
3W @ 15V per port typical |
AISG MODE OF OPERATION (AUTO SELECTED ON VALID AISG 2.0 FRAMES)
| AISG signals can be applied to either BTS0 or BTS1 port. The TMA unit switches to AISG mode when valid frames are detected on one of the BTS ports. The TMA unit is DC powered (common feed for both channels) from the port supplying the AISG frames. |
| DC supply voltage |
+7.5V to +30V DC, case is DC ground |
| AISG version |
2.0 (1.1 optional) |
| Supply current, AISG mode |
200mA @ 7.5V, 65mA @ 30V typical |
| Voltage drop, BTS to AISG port |
1.5V maximum at 2A |
| Power consumption, AISG mode |
1.5W @ 7.5V, 2W @ 30V typical |
| AISG connector, current rating |
IEC60130-9, 8-pin female / < 4A peak, 2A continuous, pin 6 |
