2To initiate a loopback, press the SPACEBAR to cycle through the loopback choices. Press ENTER to make your choice.

When prompted with the message: Are you sure (Y/N)?, press Y to initiate the loopback or N to cancel. For more information about loopbacks and troubleshooting, see “Testing” on page 42.

3To initiate a loopdown of all active loopbacks, press the SPACEBAR to select LPDN, then press ENTER . When prompted with the message: Are you sure (Y/N)?, press Y to initiate the loopdown or N to cancel.

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 16 on page 51 for a summary of the HDSL4 generic loopback

 

codes and activation methods.

 

 

Alarm Type

Indicates type of alarm.

MAL

Margin Alarm—Indicates the margin on HDSL4 loop has dropped below the threshold (0 to 15 dB)

 

set by the operator.

 

 

Armed Mode

Indicates system is in an armed state for an intelligent repeater loopback command.

 

 

BERT Status

Provides BERT Generator status, elapsed time, and BERT results.

 

 

DS1 Errors

 

ES Count

Errored Seconds—The sum of the Errored Seconds-Line (ES-L) and Errored Seconds-Path (ES-P)

 

counts detected on the DS1 input over a 24-hour period. Errors included are: DS1 frame errors,

 

BPV, and ESF CRC errors.

SES Count

Severely Errored Seconds—The sum of the DS1 Severely Errored Seconds-Line (SES-L) and

 

Severely Errored Seconds-Path (SES-P) counts over the last 24 hours.
