Part 6: Bulk warrants Chapter 3: Bulk equipment interference warrants Section 177: Meaning of "equipment data"
This section describes equipment data which can be obtained under a bulk equipment interference warrant. Equipment data means systems data or identifying data. In order to be equipment data, identifying data must be capable of being separated from the communication or item of information in such a way that, when separated, it would not reveal the meaning (if any) of the content of the communication or the meaning (if any) of an item of information (disregarding any inferred meaning).
	Systems data is defined in section 263 as data which enables or otherwise facilitates, or identifies or describes anything connected with enabling or facilitating, the functioning of any postal service, telecommunications system or any telecommunications service provided by means of the system or any other relevant system or service provided by means of that relevant system.
	Identifying data is defined in section 263 as data which can identify, or assist in identifying, any person, apparatus, telecommunication system or telecommunications service, or which identifies an event, or may be used to identify the location of any person, event or thing.
	Equipment data obtained under a bulk equipment interference warrant will be subject to the relevant safeguards set out in Chapter 3 of Part 6.
	Equipment data may also be obtained under a targeted equipment interference warrant. Secondary data comprising systems data and identifying data may be obtained pursuant to an interception warrant.
	Equipment data could include:
messages sent between items of network infrastructure to enable the system to manage the flow of communications;
router configurations or firewall configurations;
software operating system (version);
the period of time a router has been active on a network;
the location of a meeting in a calendar appointment;
