Left Side Options
Sets the Equalizer for 133 to 265 feet
Sets the Equalizer for 266 to 398 feet
Sets the Equalizer for 399 to 532 feet
Sets the Equalizer for 533 to 655 feet
Selects line code Alternate Mark Inversion (AMI)
Enables the Loopback Timeout (LBTO) to
120 minutes after initiation
Enables system response to DDS latching loopback
commands for Fractional T1 (FT1) loopback capability and
enables CP disconnect and trouble indication
Configures the system for local powering
(a) Only one of the DSX-1 line equalization switches (1 - 4) can be selected at a time. If more than one switch is enabled, the lowest value setting
has priority.
