User's Manual
1. General Information
Overview
The physical installation of each part of the TTPA system is described in separate
chapters. Testing and functioning check is described in a separate chapter. Different
kinds of system configurations are described in the last chapter.
Note that at some stages during the installation, the BTS must be turned off. To
prevent extensive downtime it may be useful to finish the stages of the installation of
both TTPA, APDU and CI when the BTS still is active. The BTS then has to be shut
down only once for finishing the installation of all included parts.
Note that all information in this manual may change without any notice. Refer to the
technical specifications for the latest information on the TTPA products.
Safety Considerations
The TTPA is equipped with a pole clamping unit. This enables the installation
personnel to first install the relatively light mast clamp, and then easily hook on the
actual amplifier. This feature reduces the risk of accidents during installation.
It is important for everyone involved in the installation, operation, and maintenance of
the TTPA, APDU and CI to understand the following points:
• The TTPA, APDU, and CI are designed to amplify the uplink signal from the
mobile phone and the downlink signal to the mobile phone. The TTPA system
must be used exclusively for this purpose and no other.
• No units included in the system (TTPA, APDU or CI) may be repaired in the
field. All malfunctioning parts must be sent back to Allgon Systems for repair or
replacement.
• Always use an ESD bracelet during installation of electrical equipment and when
touching the BTS connectors, or when handling electrical equipment, to prevent
ESD damage.
• The mounting of the TTPA on high masts, poles or roofs must be done by skilled
personnel, authorised to work on high masts, poles, or roofs. The personnel must
be aware of security regulations and use appropriate security equipment.
• The coaxial cable insulation is made of PTFE, polytetrafluoroethylene, which
gives off small amounts of hydrogen fluoride when heated. Hydrogen fluoride is
poisonous. Heating tools must not be used when stripping off coaxial cable
insulation. No particular measures are to be taken in case of fire, because the
emitted concentration of hydrogen fluoride is very low.
2. Installation of the TTPA
Outdoor conditions
The TTPA is environmentally protected (IP 65), and can be mounted without any kind
