DIB-500 R4.1 Function tests and operating surveillance
Function tests and operating surveillance GPS
3. Unblock any blocked operational carriers after at least 5 minutes with the System
release maintenance function.
The system blocking of operational carriers has been revoked.
Standby carriers are switched back to their original status.
You have successfully checked the standby carriers.
7.6 Function tests and operating surveillance GPS
The following sections describe procedures for function tests and the operational moni-
toring concerning the GPS functionality of the DIB-500 R4.1.
7.6.1 Checking the installation site of the GPS antenna
To prevent damage caused by insufficient guarding and/or fastening, the installation site
of the GPS antenna should be checked following the installation of the GPS antenna.
Proceed as follows to check the installation site of the GPS antenna
Preparation:
The installation and connection of the GPS antenna must have been completed.
Carry out the following steps:
1. Check the installation site of the GPS for proper condition such as the fastening of
the antenna mast.
Circumferential range of vision (angle of unobstructed visibility of the sky) of the
GPS antenna.
A good circumferential range of vision (angle of unobstructed visibility of the sky accord-
ing to the recommendations of the manufacturer) must be maintained to ensure proper
reception of the GPS antenna. The angle of the GPS antenna supplied is 90 °. When
using a third-party GPS antenna, heed the corresponding documentation supplied with
the GPS antenna.
2. Check the circumferential range of vision of the GPS antenna.
The visual inspection has thus been completed.
7.6.2 GPS operational monitoring (via NMC-511 FaultManager)
The PUC software component (Processing Unit Controller) monitors the operation of
the GPS module. The PUC monitors the function of the GPS receiver and the visible
GPS satellites based on the received GPS data.
The NMC-511 FaultManager network management client is convenient for rapidly
detecting and localizing faults in an ACCESSNET
®
-T IP network. This facilitates prompt
fault elimination.
