<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.

•If multiple displays of identical list configurations occur, this happens because of intermediate states of the list, that have already been overridden by new transitions and states. Thus, it is guaranteed that the configu- ration displayed in such cases is the current configuration at the time of the last display.

•It is adviseable to receive URC "^SLCC" on an interface that is not used for call initiation, if verbose output is configured. If only voice calls are expected, a setting of AT^SM20= 0 may be used alternatively in order to keep the call from blocking the interface.
