3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 301 489-1 [1] and the following apply:
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE 1: It is considered as an ancillary equipment if:
 the equipment is intended for use with a receiver or transmitter to provide additional operational
and/or control features to the radio equipment (e.g. to extend control to another position or
location);
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a
sub-unit of the main equipment essential to the main equipment basic functions).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
carrier-off state (idle mode): state of an MES when it is powered-on but not transmitting a signal, i.e. not in a
carrier-on state
carrier-on state (allocated a channel): state of an MES when it is transmitting a signal in a continuous or a
non-continuous mode
critical stored data: data that is essential for an EUT to perform a primary function in accordance with that EUT's
specification
NOTE: This may include data previously stored by the user.
drive equipment: equipment used to enable the EUT to operate as intended during the test process

and/or control features to the radio equipment (e.g. to extend control to another position or
location);
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a
sub-unit of the main equipment essential to the main equipment basic functions).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
carrier-off state (idle mode): state of an MES when it is powered-on but not transmitting a signal, i.e. not in a
carrier-on state
carrier-on state (allocated a channel): state of an MES when it is transmitting a signal in a continuous or a
non-continuous mode

3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 301 489-1 [1] and the following apply:
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE 1: It is considered as an ancillary equipment if:
 the equipment is intended for use with a receiver or transmitter to provide additional operational
and/or control features to the radio equipment (e.g. to extend control to another position or
location);
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a
sub-unit of the main equipment essential to the main equipment basic functions).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
carrier-off state (idle mode): state of an MES when it is powered-on but not transmitting a signal, i.e. not in a
carrier-on state
carrier-on state (allocated a channel): state of an MES when it is transmitting a signal in a continuous or a
non-continuous mode
critical stored data: data that is essential for an EUT to perform a primary function in accordance with that EUT's
specification
NOTE: This may include data previously stored by the user.
drive equipment: equipment used to enable the EUT to operate as intended during the test process

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 301 489-1 [1] and the following apply:
ancillary equipment: electrical or electronic equipment, that is intended to be used with a receiver or transmitter
NOTE 1: It is considered as an ancillary equipment if:
 the equipment is intended for use with a receiver or transmitter to provide additional operational
and/or control features to the radio equipment (e.g. to extend control to another position or
location);
 the ancillary equipment cannot be used without being connected to radio equipment to provide user
functions independently of a receiver or transmitter; and
 the receiver or transmitter, to which it is connected, is capable of providing some intended
operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a
sub-unit of the main equipment essential to the main equipment basic functions).
NOTE 2: An example of ancillary equipment would be a docking station for radio equipment whose interface is
dedicated to a particular product or range of products.
carrier-off state (idle mode): state of an MES when it is powered-on but not transmitting a signal, i.e. not in a
carrier-on state
carrier-on state (allocated a channel): state of an MES when it is transmitting a signal in a continuous or a
non-continuous mode
critical stored data: data that is essential for an EUT to perform a primary function in accordance with that EUT's
specification
NOTE: This may include data previously stored by the user.
drive equipment: equipment used to enable the EUT to operate as intended during the test process
Externally Mounted Equipment (EME): equipment consisting of those of the modules of the Installable Equipment
(IE) which are intended to be mounted externally to the vehicle as stated by the manufacturer

host equipment: any equipment which has complete user functionality when not connected to the MES, and to which
connection is necessary for the MES to offer additional functionality
Installable Equipment (IE): equipment which is intended to be fitted to a vehicle
NOTE: An IE may consist of one or several interconnected modules.
integral antenna: antenna designed for permanent connection to the equipment and considered part of the enclosure
port
Internally Mounted Equipment (IME): IE modules which are not defined as EME
multimode MES: equipment that accommodates radio stations of different radio systems
occupied bandwidth: See ITU-R Radio Regulations [4], part A, chapter 1, Terminology RR 147.
Portable Equipment (PE): radio equipment intended for portable use and powered by integral batteries or battery
NOTE 1: A PE would normally consist of a single module, but may consist of several interconnected modules.
NOTE 2: More than one of the equipment classifications can apply to certain equipment, as described in clause 5.4,
dependent upon the manufacturer's declaration of normal intended use.
transmission disabled state: state of an MES when it is not authorized to transmit by the Network Control Facilities
(NCF)
