Functionality Administration
"Functionality Administration" provides the functionality necessary to
allow the BSC to configure, enable and disable AOs within the RBS.
This function also includes general layer 3 A-bis OML support for other
functions within the RBS.

Concepts
Elementary Procedure
The protocol over the A-bis OML at layer
3 consists of EPs (Elementary
Procedures). An EP is a unit of interaction
between the BSC and one of the MOs. An
EP consists of an initiating message and a
response. For example, an EP may consist
of the BSC sending an initiating message
CONFIGURE REQUEST and the MO in
the RBS responding with a message
CONFIGURE REQUEST ACK.
RU
Replaceble Unit. An RU is the smallest
unit that can be handled on site or in a
repair center and of which information can
be retrieved via OMT or BSC.
AO
Application Object. An abstract subclass
of MO, which provides part of the
functionality of a BTS
MO
Managed Object. The BSC manages the
O&M of the RBS via the A-bis O&M
Interface. The RBS equipment is seen as
MOs by the BSC. This is a means of
describing the RBS in a functional-
oriented way, and a logical model of the
RBS in terms of MOs is built in the BSC.
All O&M actions are based on this logical
model structure created in the BSC.
An MO does not necessarily have a one-
to-one relation with a physical unit in the
RBS, and the MO comprises either both
hardware and software or software only.
See also Figure 140 on page 340.
SO
Service Object. An abstract subclass of
MO, which provides service functions for
a set of MO instances including itself.
