5.4 Base Units Interface Definition
By default, the Base Units are factory configured to connect to a passive BTS/BDA interface type.
If an RIU is included in the installation, the BTS/BDA interface for each BU must be defined
accordingly.
NOTE: The relevant Base Units are displayed under the group of host BTSC module(s) In the Topology
Tree. Each Base Unit is displayed according to its 4-port modules, where each 4-port module is referred to
as OPTM.
To verify and modify the Base Unit interface configuration
1. To invoke the BU configuration dialog, do one of the following:
• Double-click on the first OPTM node in the tree, or
• Double-click the
empty space in the OPTM in the Base Unit view. Do not click on the
LEDs in the OPTM –
this will invoke the RU configuration dialog.
2. Click the Advanced tab. In the BTS Interface Type field, verify that the correct option is
selected: RIU or Passive, according to the BTS/BDA interface.
