7

alternating voice/data, data mode (only in connection with single numbering

 

scheme AT+CSNS)

8

alternating voice/fax, fax mode (only in connection with single numbering

 

scheme AT+CSNS)

<mpty>(num)

 

0

call is not one of multiparty (conference) call parties

1

call is one of multiparty (conference) call parties

 

<traffic channel assigned>(num)

0

No traffic channel is available to the call

1

mobile has been assigned a traffic channel.

 

It is now possible to send or receive inband information, e.g. to send DTMF

 

tones (cf. AT+VTS), or to receive network announcements.

<number>(str)

phone number in format specified by <type>

<type>(num)

type of address octect

145

dialing string <number> includes international access code character '+'

129

otherwise

<alpha>(str)

Alphanumeric representation of <number> corresponding to the entry found in phonebook; used character set should be the one selected with command AT+CSCS (Select TE Character Set).

The maximum displayed length of <alpha> is 16 characters. If <alpha> has more than 16 characters, only the first 15 characters will be displayed. To indicate an overflow, a special character will be used as the 16th char- acter. This will be a space if the character set selected with AT+CSCS is 'GSM', or 'E400' if the character set is 'UCS2'.

Due to time constraints on the necessary evaluation of the phonebook, this parameter may show a default value during early call phases (e.g. for <stat>= ''dialing'', ''incoming'' or ''alerting''), even if a phonebook entry is present for the number concerned.

Notes

Teleservices other than voice, data, fax are not fully supported by ME. They are used only in connection with the handling for AT+CSNS, and may therefore occur in parameter <mode> for mobile terminated calls.

If a URC "^SLCC" in verbose mode (see AT^SCFG) has been buffered while the interface was in dedicated mode (depending on the settings of AT+CMER parameter <bfr>), each buffered event indicator will be output as a separate URC after the interface returns to idle mode.

However, the output will deliver the list of current calls in the "current" state (at the time when the output is generated), possibly leading to multiple displays of identical list configurations.

Some parameters of AT command AT+CHLD, as well as some situations where the call status in the network changes very quickly (e.g. the transition between <stat>= ''unknown'', ''dialing'' and ''alerting'' for a call to a reachable subscriber within the registered network) may lead to quasi-simultaneous changes to the states of one or several calls in the list, possibly leading to multiple displays of identical list configurations.
