| work) controlled by a single front panel |
| switch |
LED Status: | The following LEDs are displayed on the |
| front panel: |
| Fiber: The green Fiber LED indicates reli- |
| able data on the fiber side |
| E1: The green E1 LED indicates reliable |
| data on the G.703/G.704 side |
| LOS: The red LOS indicates that syncro- |
| nization between modems has not been |
| established. Blinking red LOS LED indicates |
| the presense of coding errors |
| NS: The red NS LED indicates that the sig |
| nal on the fiber side is too weak to be |
| detected |
| ER: Flashing red ER LED indicates errors in |
| 511 test pattern |
| TM: The yellow TM LED indicates that |
| modem is in a test mode |
| (Local/Remote Loopback or 511/511E test |
| pattern). Opaque TM LED indicates normal |
| operation. |
