## Digital Link Supervisor

This dialog displays the data of the Digital Link Supervisor and all digital links of the system.

To access the dialog, open the “Maintenance” menu in the Configuration directory tree and click on “Link Supervisor”.

### Supervisor state codes

Code | Description
00 | Supervisor has not started.
10 | System synchronization by external source.
11 | Stabilization of link synchronization.
12 | Start link synchronization.
13 | Stop link synchronization.
14 | System is without synchronization. No external source.
40 | System is the master system. All links are synchronized by own clock. All links in our system are link masters.

### Link state codes

The link priority shows the programmed order in which the links are assigned as synchronization masters. If no value is displayed, no priority has been programmed. If no link has a programmed priority, the system works as master system and is responsible for synchronization.

Code | Description
20 | OK
30 | Used in OK/stabilization phase.
31 | Link faulty, slip.
32 | Link faulty, fault other than slip.

### Alarm state codes

The alarm state code consists of two bytes (0-7), whereas each digit indicates a certain alarm type.

##### First byte:

bit 0 |  | LOS - Loss of signal |
bit 1 |  | AIS - Alarm indiction signal |
bit 2 |  | LFA - Loss of frame alignment |
bit 3 |  | EBR - Excessive biterror rate |
bit 4 |  | RAI - Remote alarm indicator |
bit 5 |  | LMF - Loss of multi-frame synchronization |
bit 6 |  | LMFR - Loss of multi-frame synchronization, remote |
bit 7 |  | CCEI - Continuously CRC error Information (only if data is available) |

##### Second byte:

bit 7 |  | SLIP - Network/system clock difference |
bit 7 |  | SLIP1 - Network/system clock difference when link is synchronization master |
bit 7 |  | SLIP2 - Network/system clock difference when link is not the master |

### Slip count modes

The slip count mode determines the maximum slip-rate allowed before an alarm event is signaled. To set the rate, change the measurement time. The maximum value is always = 9.

Mode | Description
00 | Slips are not counted
01 | Link is not the master; period of 60 minutes
02 | Link is the master; period of 70 days
03 | Forced synchronization master; period of 10 minutes

### TEI Value

The TEI value (Terminal Endpoint Identifier) identifies the call specific settings of the T-interface. You can assign the value by system programing (non-automatic assignment) or you can retrieve the value from the connected network (automatic assignment). The command 1030 is defined for a non-automatic assignment.

##### Possible TEI Values:

0 - 63: programmable, non-automatic assignment.

64 - 126: automatic assignment.

#### Actions:

Reload |  | To reload the current data block. |
Reset Alarm Counters |  | To reset the selected alarm counters. |
Reset All Alarm Counters |  | To select all alarm counters for reset. |
