The present document specifies the technical characteristics to be provided by TErrestrial Trunked Radio (TETRA) terminal equipment@ which uses the TETRA technology. It applies to terminal equipment operating within the frequency ranges@ which are expected to be allocated to TETRA when member states have implemented ERC Decision ERC/DEC/(96)/4 [44]. The objective of the present document is to ensure that no disturbance occurs to the public telecommunications network@ to ensure proper inter-working of TETRA terminals with TETRA networks@ so that communication can be routed successfully through the applicable network(s)@ and to ensure interworking of TETRA terminal with TETRA terminal under control of a network management mechanism to avoid interference. In addition to the present document@ other Harmonized Standards may apply. Requirements apply to the network interface and the Radio Frequency (RF) Air Interface of the equipment. TETRA terminal equipment consists of several elements. The present document is structured to enable the approval of the individual elements as separate items. Because of the need for effective use of the radio spectrum@ the essential air interface characteristics will always apply. For each essential requirement a test is given including measurement methods. In the present document there are no Electromagnetic Compatibility (EMC) requirements in terms of the Terminal Directive 98/13/EC [41]@ article 5c. NOTE: Technical requirements for EMC performance are covered by the relevant standards applicable to the EMC Directive 89/336/EEC [43] which also lays down the conformity assessment procedure. The present document is based on the radio and protocol provisions of ETS 300 392@ ETS 300 394 and ETS 300 396.
