2.2.3.2 System Settings

Use this screen to adjust the defaults for:

DISPLAY ALL EOC MESSAGES

• ON: will display far end values for CRC, SES, ES, UAS, and
LOSW (if available). At this time, the module does not support
this mode.
• OFF: is the default.

SNR MARGIN THRESHOLD

Adjust by using +1 (F1) or -1 (F2). The threshold can be OFF, or
adjusted between -15 through +15 dB. If the SNR margin is less
than this setting, then the ALARM LED will be on.

LOOP ATTEN THRESHOLD

Adjust by using +1 (F1) or -1 (F2). The threshold can be OFF, or
adjusted from 1–127. The default setting is OFF. If this setting is
exceeded, then the ALARM LED will be on.

RECEIVE EOC SNR OFFSET

For reporting via the EOC (for STU-C/R only).
• ON: for far end sending SNR raw values to near end.
• OFF: for far end sending SNR margin values to near end. OFF
is the default.

SEND EOC SNR OFFSET

For reporting via the EOC (for STU-C/R only).
• ON: for near end sending SNR margin values to far end. ON
is the default.
• OFF: for near end sending SNR raw values to far end.

TRANSFORMER RATIO

• ON: the transformer ratio is set to 5:4:1. ON is the default.
• OFF: the transformer ratio is set to 4:1.
CAUTION: If the reported loop attenuation is significantly differ-
ent between the STU-R and STU-C, ensure that the transformer
ratio used is the same.
When finished press ENTER to update and save the changes.
