Maxon Telecom MM-6280IND manual Applicable in read command response

Test command returns a set of five parameters, each representing an operator present in the network. A set consists of an integer indicating the availability of the operator <stat>, long and short alphanumeric format of the name of the operator, numeric format representation of the operator and access technology. Any of the formats may be unavailable and should then be an empty field. The list of operators shall be in order: home network, networks referenced in SIM or active application in the UICC (GSM or USIM) in the following order: HPLMN selector, User controlled PLMN selector, Operator controlled PLMN selector and PLMN selector (in the SIM or GSM application), and other networks.

It is recommended (although optional) that after the operator list TA returns lists of supported <mode>s and <format>s. These lists shall be delimited from the operator list by two commas.

NOTE:	The access technology selected parameters, <AcT>, should only be used in terminals capable to register
	to more than one access technology. Selection of <AcT> does not limit the capability to cell
	reselections, even though access technology is selected, the phone may still re-select a cell in other
	access technology.

	value	<mode>:
		0	automatic (<oper> field is ignored)
		1	manual (<oper> field shall be present, and <AcT> optionally)
		2	deregister from network
		3	set only <format> (for read command +COPS?), do not attempt
			registration/deregistration (<oper> and < AcT> fields are ignored); this value is not
			applicable in read command response
		4	manual/automatic (<oper> field shall be present); if manual selection fails, automatic
			mode (<mode>=0) is entered
		<format>:
		0	long format alphanumeric <oper>
		1	short format alphanumeric <oper>
		2	numeric <oper>
		<oper>: string type; <format> indicates if the format is alphanumeric or numeric; long
			alphanumeric format can be upto 16 characters long and short format up to 8
			characters (refer GSM MoU SE.13 [9]); numeric format is the GSM Location Area
			Identification number (refer TS 24.008 [8] subclause 10.5.1.3) which consists of a
			three BCD digit country code coded as in ITU-T E.212 Annex A [10], plus a two BCD
			digit network code, which is administration specific; returned <oper> shall not be in
			BCD format, but in IRA characters converted from BCD; hence the number has
			structure: (country code digit 3)(country code digit 2)(country code digit 1)(network
			code digit 3)(network code digit 2)(network code digit 1)
		<stat>:
		0	unknown
		1	available
