Product description
Components of the DIB-500 R4.1
PowerPC
The PowerPC is a hardware component and an integral constituent of the TIB. The fol-
lowing software components use the PowerPC as the hardware platform:
|
Switching and Routing Server (SRS)
|
Processing Unit Controller (PUC)
Switching and Routing Server (SRS)
The Switching and Routing Server (SRS) is a software component. It establishes the
connection to an SRS of another network element via the Point-to-Point Protocol (PPP).
In this way, the components of the network elements in the radio system can communi-
cate via IP to exchange signalling data. The SRS uses one or multiple channels of an
E1 line and can thus connect several network elements with each other at the same
time.
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 is a hardware subcomponent within the MSU. It is responsible for pro-
viding the clock and time reference signals required for synchronizing 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).
3.2.1.2
IntelPC
The IntelPC is a hardware component and an integral constituent of the TIB. The follow-
ing software components use the IntelPC as the hardware platform:
|
|
Network Element Manager (NEM-523)
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, it manages the TETRA radio cell including control of the broadcast data.
Network Element Manager (NEM-523)
The Network Element Manager (NEM) is part of the network management system of
ACCESSNET
®
-T. It administrates the network elements and facilitates the access to
the network components installed in the TETRA infrastructure.
