Configuring DS1 Services through the HXU-357
This section provides instructions for configuring a single line from the HXU Root Menu. After the DS1 line is
configured, the line unit, any necessary doublers, and the HRU are installed as described in the sections which
follow. The final step is to place the line in service to allow reporting and lockout further changes.
The DS1 line being configured must be set to Unequipped and Out-of-Service to allow configuration
changes and prevent unwanted alarms. This is the default setting; it should not require adjustment.
If you need to change the configuration of the DS1 line, follow these instructions.
