LTPH-SM-1014-03, Issue 3
After initial installation, the HXU-357 multiplexer unit must be configured properly or continuous alarms will
occur when the DS1 interface is placed in operation mode. During installation, the DS1 interface should be
configured as Out-of-Service and Unequipped (Maintenance mode). The DS3 interface is configured as
Out-of-Service.
These settings do not effect the transmitted payload, they only suppress the alarms and allow
for modification.
Setting Up the Communications Channel through the HXU-357
The AUX port is not available to the user as a craft interface when any multiplexer is used in the shelf. HMU-319
List 7A automatically sets up the AUX port when the IP address is assigned to support IP network communication
with the HXU-357.
