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

Table 8. Monitor Screen Descriptions
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.
