Siemens MC55 AT manual To the user

The "vmwait" indicators do not apply if a network provider signals new voice mail(s) via standard SMS. In this case the indicator "message" will be displayed (see AT+CIND).

"vmwait2"	Voice Message Waiting Indication for line 2
	0	See description of "vmwait1".
	1	See description of "vmwait1".
"ciphcall"	Ciphering Status Change Indication
	0	Current call or SMS is not ciphered.
	1	Current call or SMS is ciphered.
	As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
	allows the MC55 to detect that ciphering is not switched on and to indicate this
	to the user.
	The ciphering indicator feature may be disabled by the home network operator
	setting data in the "administrative data" field (EFAD) in the SIM, as defined in
	GSM 11.11.
	If this feature is not disabled by the SIM, then whenever a connection is in
	place, which is, or becomes unenciphered, an indication shall be given to the
	user. This enables the user's decision how to proceed.
	Read command returns valid ciphering status only if a call is in progress or
	active.
	If EFAD setting disables the ciphering indicator feature read command always
	indicates a ciphered link and no URC presentaion will take place.
	The following restrictions apply if the same serial channel is used for AT^SIND
	"ciphcall" indication and for the action triggering this URC. In general, the rec-
	ommended solution is to use a dedicated channel for all status signalling via
	URCs.
	• If an unciphered mobile originated SMS is performed, AT^SIND "ciphcall"
	URCs on the same serial channel will be issued after the related "OK" and
	indicate the ciphering state at this time. Because the SMS is already sent at
	this time, two URCs will be issued on this channel, but both are indicating
	that ciphering is enabled.
	• If an unciphered mobile originated data call is performed, AT^SIND "ciph-
	call" URCs on the same serial channel will be issued after the interface is
	not longer blocked by the call (call is released or temporarily stopped) and
	indicate the ciphering state at this time.
"eons"	Enhanced Operator Name String (EONS) Indication
	The Enhanced Operator Name String indicator feature allows the MC55 to out-
	put various operator names for different PLMN identities via URC. It also allows
	the output of a different operator name based on a subset of the registered net-
	work by using a range of Location Area Codes (LACs) or a single LAC.
	The presentation of the "eons" indicator is determined by network activity. For
	example, the indicator appears every time a location update occurs or a NITZ
	information is sent, no matter whether or not the status of the EONS informa-
	tion has changed. This means that the same EONS information may be
	reported several times.
	The EONS tables are stored in the SIM card and will be read at power-up.
	Following are the SIM Elementary Files that are affected by the introduction of
	EONS feature in the SIM card:
	EFSST	(SIM Service Table) - describes which features are active.
	EFOPL	(Operator PLMN List) - contains the PLMN identification and location ID
	together with the index of the corresponding PNN record
	EFPNN	(PLMN Network Name) - contains the full and short form version of the
	network name for the registered PLMN

If the Operator Name Source is CPHS Operator Name String long and short form, refer to <indValue>, the following two SIM Elementary Files will be used:
