4.7 Defining Present RUs

This section describes how to check and, if necessary, define the RUs which a represent (or not present) in the RBS. To avoid Hardware and IDB inconsistency, the RBS must know which RUs should be present. By setting RUs to Present/Not present, the RBS recognizes

which RUs can be used (present) and which are not present. The following RUs are not automatically updated and must therefore be defined:

• PDU

• SAU

The following RUs are automatically marked as present when the RU is detected:

Note: The RUs cannot be removed when in traffic.

Radio Unit Define the RUs Present/Not present as follows:

1. Select Configuration > Define > Present RUs... to open the Define Present RUs window.

2. If necessary, move the RUs in the configuration used to the Present box

by selecting the RU to be moved and clicking the key (or double-clickingthe RUs to be moved). If RUs Not Present in the configuration are in the Present box, then move

them to the Not Present box by clicking the key. 3. Click OK when finished.

Defining CPRI Parameters

This section describes how to define the Common Public Radio Interface (CPRI) parameters. For an overview of the available

The Common Public Radio Interface (CPRI) standard defines the interface of base stations between

the Radio Equipment Controllers (REC) in the standard, to local or remote radio units, known as Radio

Equipment (RE).

Parameters settings for CPRI parameters, seeTable below

Parameter Valid values Default Description

Interface type

Optical

Optical the parameter defines the cable connection type for the CPRI interface. If the parameters not comply with the cable type, the CPRI link cannot be established.

Electrical

Mode type

Master

Master The parameter defines the CPRI port mode. A CPRI port connected to a RUS must always be defined as master. A CPRI port on DUG can be defined as slave if cascaded digital units are supported.

Defining MCTR Configuration

This section describes how to define the Multi Carrier Transceiver (MCTR) configuration. The number of TRXs per MCTR can be changed using create IDB.

1. Select Configuration > Define > MCTR... to display the Define

MCTR Configuration dialog box. 2. Select the applicable MCTR instance from the list. 3. In the Power Distribution box, select the MCTR configuration.

* Additional information:

The Power distribution can be set in MCTR configuration is depending on theTRX configuration defined in RBS:

• For config 1/1/1 power must be/can set as 47 dBm (max value)

• For config 2/2/2 power must be/can set as 45 or 43 dBm (max Value)

• For config 3/3/3 power must be/can set as 43 dBm (max Value)

Defining TEI

This section describes how to define the TEI value. To enable the BSC to communicate with

the CMRU of an RBS in a cascade chain, a unique TEI value between 12 and 63 needs to be set for each RBS in the chain. The TEI value for the RBS must also match the TEI value the BSC uses to identify the RBS. For RBSs not connected in a cascade chain, the default TEI

value can be used.

1. Select Configuration > Define > TEI... to open the Define TEIwindow.
