dialing string

includes international access code character '+'

otherwise

Alphanumeric representation of

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

is 16 characters. If

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

= ''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

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

), 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

= ''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.
