TIA TSB-102.BAFA-A:1999 (R2013)

Project 25 systems have subscriber units and fixed equipment
which comprises the infrastructure. There are a number of external
interfaces to the system, and specifically this document addresses
the Network Management Interface En.

The objective of the Network Management Interface is to ensure a
standardized interface between the End System Network Management
Center (NMC) and an Operations and Maintenance Center – Radio
Frequency (OMC-RF) located within a Radio Frequency Sub-system, so
that an NMC can manage Radio Frequency Subsystems (RFSS) sourced
from other vendors. The network management interfaces between the
fixed RFSS equipment and the OMC-RF could be standardized, but are
beyond the scope of the Project 25 standard.

The Network Management Interface is part of an intended suite of
standards necessary for interoperability. A general overview of the
Project 25 standard exists in the Project 25 System and
Standards Definition [1]. The reader should have familiarity
with this document.

The following three sections will identify the proposed
standards for: 1) the Network Management hierarchy, 2) the
transportation medium of Network management information between an
NMC and an OMC-RF, and 3) the definition of the Project 25 system
management functional areas.
