Field | Description |
|
|
Active Loopback | An active loopback is indicated on the lower third of the Monitor screen. Available loopbacks are |
| indicated by gray text. See Table 15 on page 40 for a summary of the HiGain loopback codes. |
Alarm type | Indicates type of alarm. |
Armed mode | Indicates system is in an armed state for an intelligent repeater loopback command. |
Code type | Type of DS1 line coding received or sent (B8ZS or AMI). |
DS1 ES Count | Errored |
| counts detected on the DS1 input over a |
| BPV, and ESF CRC errors. |
DS1 SES Count | Severely Errored |
| Severely Errored |
DS1 UAS Count | Unavailable Errored |
| absent over a |
Frame type | Type of DS1 framing detected at the input stream (SF, ESF, or UNFR). |
HDSL2 ES Count | Errored |
| error. This value is a running total of the last 24 Hours. |
HDSL2 SES Count | Severely Errored |
| or one or more LOSW defects. (An LOSW defect occurs when at least three consecutive HDSL |
| frames contain one or more frame bit errors.) This value is a running total of the last 24 hours. |
HDSL2 UAS Count | Unavailable Errored |
| after 10 contiguous HDSL SES and is retired after 10 contiguous |
| a running total of the last 24 hours. |
ID | Circuit identification (ID) number. |
LA | Loop |
| Interlocking Spectra (OPTIS) pulse from the distant end. The value is related to the loop attenuation |
| at 196 kHz and should be kept under 35 dB. |
LPF | Line Power |
M | |
MAL | Margin |
| as set by the operator. |
PL (or HG) | PL displays when the loopback was initiated by a command embedded in the DS1 data path |
| payload (PL). HG displays when the loopback was initiated from a HiGain Generic (HG) front panel |
| or by a HiGain maintenance terminal loopback command. |
PRM | The sum of the Performance Report |
| |
System Status | The presence or absence of an alarm condition is indicated on the lower right corner of all screens. |
| System: OK indicates that there are no alarms present; System: Alarm indicates the presence of |
| an alarm. Refer to “Using the Performance Screens to View Alarm Data” on page 30 for detailed |
| alarm information. |
