DXU-21
ESB
This interface is used to synchronize several transceiver groups in the same
cell, for example when one cell is built up by more than one RBS.
The interface is accessed on the front of the DXU through a D-sub 9-pin male
connector marked ‘‘ESB’’.
5.2 Operator Interface
This section describes the operator interface, which consists of the OMT
interface and indicators and buttons.
OMT
The OMT port is used to communicate with the Operation and Maintenance
Terminal.
The OMT is connected through a 9-pin D-sub female connector.
The OMT connection is galvanically separated. All signals use RS 232 levels.
