Line Code | Toggle | AUTO | When the RLX line code is set to AUTO, | AMI | |
|
|
| the module senses the line code and |
| |
|
|
| switches from AMI to B8ZS if an encoded |
| |
|
|
| signal is detected. After switching to |
| |
|
|
| B8ZS, the RLX stays locked in this line |
| |
|
|
| code until an LOS is detected at both DS1 |
| |
|
|
| inputs. |

BER Threshold | Toggle | Range of | The average Bit Error Ratios of both the | ||
|
|
| incoming DS1 signals are monitored by |
| |
|
|
| the RLX. By monitoring BERs, the RLX |
| |
|
|
| is capable of triggering a minor alarm |
| |
|
|
| when any of the monitored signals |
| |
|
|
| degrades below the BER threshold level. |
