Unit Description, 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,
or one cell is split between two RBSs. Note that a master-slave
configuration, as in RBS 2202, is regarded as one transceiver group.
The interface is accessed on the front of the DXU through a D-sub
9–pin male connector marked "ESB".
6.4.1 OMT
The OMT port is used to communicate with the Operation and
Maintenance Terminal.
Connectors
The OMT is connected through a 9–pin D-sub female connector.
Electrical
The OMT connection is galvanically separated. All signals use RS 232
levels.
Table 76 The OMT pins and their functions
Pin Function
1
DCD, looped from DTR (pin 4)
2
RXD, data out of DXU
3 TXD, data into DXU
4
DTR, looped to DCD (pin 1) and DSR (pin 6)
5
Signal ground
6
DSR, looped from DTR (pin 4)
7
RTS, looped to CTS (pin 8)
8
CTS, looped from RTS (pin 7)
9
RI not connected
Note: The connector is configured as a DCE, and thus should be
connected to an IBM PC style DTE (such as a computer)
with a straight cable.
6.4.2 Test Interface
This interface is used for test purposes only. It consists of a buffered
version of the 13 MHz signal from the OVCXO. The signal is
sinusoidal shaped and is suited for a coaxial cable load of 50
.
Connectors
The test interface has an SMB connector.
