DIB-500 R4.1 Product description
Constituents
Processing Unit Controller (PUC)
The Processing Unit Controller (PUC) is a software component and serves for commis-
sioning, configuring, controlling and monitoring the integrated hardware components of
the TIB. The PUC makes the resulting data available to the Network Management Sys-
tem via an SNMP agent.
The PUC is also responsible for the signalling between the transceivers and the TETRA
Operation Server (TOS). The PUC forwards the signalling from the transceivers to the
TOS or, the signalling from the TOS via the air interface back to the transceivers.
GPS module
The GPS module (Global Positioning System, GPS) is a hardware component within
the MSU and ensures the provisioning of the reference signals for clock and time that
are required for the synchronisation of the components within the network element. For
this purpose, the time signal received from the PUC software component is processed
and forwarded to the PowerPC as a reference signal. From there, the reference signal
is distributed with the aid of the Network Time Protocol (NTP).
3.1.5.4 IntelPC
The IntelPC is a hardware component and, depending on the network configuration,
serves as hardware platform for the following software components:
| Core Operation Server (COS)
| TETRA Operation Server (TOS)
| IP Switch (IPS)
| Network Element Manager (NEM-523)
| Packet Data Server (PDS)
| TETRA Application Platform (TAP)
| SIP Media Gateway (SMG)
| Hardware Guard (HWG)
Core Operation Server (COS)
The Core Operating Server (COS) is a software component which performs all calcula-
tions and control for exchange processes of higher protocol layers. Apart from the
switching process, this includes the call administration, the authorisation validation and
- if applicable - the resources management for the communication with other network
elements within an ACCESSNET
®
-T IP network. In addition the COS assumes the con-
trol of the software component IP switch.
TETRA Operation Server (TOS)
The TETRA Operation Server (TOS) is responsible for the mobility management (regis-
tration, group handling, authentication and call management with speaker monitoring,
etc.). In addition, the TOS is responsible for the resource management for the radio
channels and manages the TETRA radio cell including control of the broadcast data.
