TDM traffic load
Encapsulated data
The NIDU supports separate management and TDM data protocol interfaces. The management
interface is between the NIDU and a directly-connected ODU. The TDM data interface is
between peer NIDUs. The ODU does not interact with the TDM data protocol, except in as
much as it provides a separate high priority queue for encapsulated TDM data at the wireless
interface.
The resulting traffic load for encapsulated TDM data is shown in Table 98.
