Transport network O&M functions-DXX Support
51.4 Functions
51.4.1 Enabling and detection of TNOM protocol
This function is initiated when the parameter TNOM_use in the RBS
database is set to on.
This function is used to control the enabling and disabling of the
Transport Network O&M functions in RBS 2000. The parameter
TNOM_use stored in RBS DB is used for this.
When the function is disabled no management timeslot is dedicated for
the Transport Network O&M functions. Instead the timeslot will be
used by BSS for internal use i.e. for traffic and signalling.
When is enabled the Transport Network O&M functionality is active,
and will work as described in this function specification. The first
received message after the function has been enabled is detected and
enables the protocol stack for the received protocol if recognized.
If the protocol is not recognized no protocol stack is enabled. This
functionality can be regarded as an auto detection of TNOM protocol
type.
51.4.2 Allocation of TNOM timeslot
This function is initiated during restart of the DXU if the parameter
TNOM_use in RBS DB is already set to ON, otherwise the function is
initiated when the parameter is set to ON.
The communication between RBSes or RBS and DXX is performed on
a 64 kbit/s timeslot in the PCM link. The PCM link is either 2048 or
1544 kbit/s.
This function allocates a 64 kbit/s timeslot for the TN O&M
management channel. When RBS is configured as stand alone, one
timeslot with the same timeslot number is allocated for both PCM-A and
PCM-B. When RBS is configured in cascaded chain , the same timeslot
number is used for PCM-A and PCM-B. A full 64 kbit/s timeslot is
used, thus not supporting FDL or spare bits in TS 0 to be used.
The TNOM timeslot number is stored in RBS DB.
The TNOM timeslot has priority to the access of timeslots within RBS.
Timeslot used for TNOM will be removed from available timeslots
shown in capabilities.
51.4.3 DXX Node identity
This function is initiated during restart of the DXU if the parameter
TNOM_use in RBS DB is already set to ON, otherwise the function is
initiated when the parameter is set to ON.
This function sets and changes the Node id for the RBS. The RBS node
has a unique node identity (a node number) for communication with the
DXX network and for appearance in the NMS. The node identity is
stored in RBS DB and has not to be the same as RBS TEI value.
The node identity can be set and changed from the OMT, as well as
from the DXX. No one has priority on the parameter , i.e. the last value
set is the valid node id.
