Network/Status Alarms
Chapter 1 Introduction
The six Network/Status Alarms, labeled RED, YEL, BLU, TEST, SYNC, and LOS, display PRI network activity during system operation. The front panel also has four system status LEDs labeled ATTN, STAT, TRAF, and STATUS that display operational status conditions for the Remote Annex 6300. Table
Technical Support personnel can use this information to diagnose problems.
If you are using an external CSU, some of the Network/Status alarm LEDs may not give true readings. In this case, defer to the status and alarm conditions indicated on the external CSU.
Table
Alarm | Description |
|
|
RED | RED alarm LED is ON during a locally detected carrier failure. |
| During the RED alarm condition, a YELLOW alarm is |
| transmitted across the telephone network. |
YEL | YELLOW alarm LED is ON when receiving a YELLOW alarm |
| condition from the telephone network. |
BLU | BLUE alarm LED is ON when receiving an unframed, |
| Alarm Indication Signal (AIS) from the network. This condition |
| exists upon a loss of originating signal, or when any action is |
| taken that would cause a signal disruption. |
TEST | RED network TEST LED is ON when the ISDN Network |
| Interface is looped back. Loopback tests are activated either |
| locally by the user or by the telephone company. |
SYNC | GREEN SYNC LED is ON when the PRI interface is properly |
| synchronized with the received network signal and is receiving |
| proper framing information. |
