Transport network O&M functions-DXX Support
TNOM timeslotThe parameter used for the Transport Network O&M
Timeslot allocation is:TNOM_timeslot
The valid range of the parameter is:131 for E1124 for T1
TNOM node IdThe parameter used for the Transport Network O&M
Node Id allocation is:TNOM_nodeid
The valid range of the parameter is:165534
The parameters can be modied from the OMT. The parameter
TNOM_nodeid can be modied from DXX as well. The new settings
are activated immediately.
51.4.13 Administration of DXX specic functions
The DXX specic functions are maintained via the interface

51.4.14 DXX Protocol Handling
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 DXX protocol is implemented as four layers in the ISO OSI layer
model, layer 1,2,3 and 7. These layers correspond to physical link
layer, data link layer, network layer, and application layer respectively.
