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

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

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

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
