Command Description
TA attempts to set up an outgoing call to the stored number. The termination character ";" is mandatory since
dialing from a phonebook is only supported for voice calls and for sending *# codes of Supplementary Services
or other functions.
Parameter Description
<n>(num)
Integer type memory location in the range of locations available in the selected memory, i.e. the index number
returned by AT+CPBR.
<mgsm>(str)
String of GSM modifiers:
I
Activates CLIR (disables presentation of own phone number to called party)
i
Deactivates CLIR (enables presentation of own phone number to called party)
Notes
• This command may be aborted generally by receiving a character during execution. Abortion is not possible
during some states of connection setup such as handshaking.
• The command is not applicable to data calls. Any attempt to dial a data call number from <n> causes the
result code "NO CARRIER" to appear.
• Parameter <mgsm> only if no *# code is within the dialing string.

Command Description
This command searches the active phonebook for a given string <str> and dials the assigned phone number.
The termination character ";" is mandatory since dialing from a phonebook is only supported for voice calls and
for sending *# codes of Supplementary Services or other functions.
Parameter Description
<str>(str)(+CSCS)
String type value ("x"), which should equal an alphanumeric field in at least one phonebook entry in the searched
memories; used character set should be the one selected with AT+CSCS. <str> can contain escape sequences
as described in chapter "Supported character sets".
<str> must be wrapped in quotation marks (""), if escape sequences or parameter <mgsm> are used or if the
alphanumeric strings contains a blank. If not, quotation marks are optional.
If AT+CSCS is set to "UCS2", with respect to the coding of UCS2-characters only phonebook entries that contain
an alphanumeric string with as size less than the half of the parameter <tlength> from AT+CPBW can be
dialed.
<mgsm>(str)
String of GSM modifiers:
I
Activates CLIR (disables presentation of own phone number to called party)
i
Deactivates CLIR (enables presentation of own phone number to called party)
Notes
• This command may be aborted generally by receiving a character during execution. Abortion is not possible
during some states of connection setup such as handshaking.
• The command is not applicable to data calls. Any attempt to dial <str> without semicolon ";" causes the
result code "NO CARRIER" to appear.
• Parameter <mgsm> only if no *# code is within the dialing string.

Command Description
This command redials the last voice and data call number used in the ATD command. If terminated with semi-
colon ";" ATDL dials the last voice call number stored in the "LD" phonebook. Otherwise, the last dialed data or
fax number will be used (not contained in the "LD" phonebook).

disconnect from line and terminate call
Notes
• OK is issued after circuit 109 (DCD) is turned off, if it was previously on.
• ATH terminates every circuit switched call (voice, data or fax), even if it is issued via another interface. This
behavior is in accordance with ITU-T V.250; (07/97, "Hook control": "ATH is terminating any call in progress.").
• ATH clears any active PDP context or terminates any existing PPP connection, but only if issued on the same
interface where GPRS is used and if there is no pending network request for PDP context activation. It does
not affect PDP contexts and PPP connections on other interfaces (see also Chapter "ATH Manual rejection
of a network request for PDP context activation").

Command Description
The write command serves to end one specific call or all calls known to the ME, indicating a specific GSM04.08
release cause specified by the user. The command can be used for voice, fax and data calls in any call status
(i.e. any calls listed by AT+CLCC).
Parameter Description
<cause>(num)
release cause
Release cause from GSM04.08 to be indicated to the network.
The TC65 will release the selected connection(s) with release cause indication "cause" and location "user" (0)
in the "disconnect" protocol message to the GSM Network. It depends on the network whether or not the release
cause will be forwarded to the remote party.

27
Send GSM04.08 release cause "Destination out of order "
31
Send GSM04.08 release cause "Normal, unspecified"
<cn>(num)
call number
The "call number" is an optional index into the list of current calls available via AT+CLCC. AT command AT^SHUP
will terminate the call identified by the specified call number. The default call number "0" is not assigned to any
call, but signifies "all calls". As "0" is the default value, it may be omitted.
With AT^SHUP, Calls will be terminated regardless of their current call status, which may be any of the states
allowed by AT+CLCC.

Parameter Description
<n>(num)(&W)(&V)
000(&F)
Automatic answer mode is disabled.
001-255
Enable automatic answering after specified number of rings.
Notes
• This command works for MT data and fax calls.
• Autoanswering of CSD data and fax calls is supported on ASC0/Mux1 only.
• If <n> is set to higher values, the calling party may hang up before the call is automatically answered.
• The correlation between ATS7 and ATS0 is important.
Example: Call setup may fail if ATS7=30 and ATS0=20.
• Setting is local to the interface. It is allowed to have different settings on different interfaces. In such cases
the interface 'wins', which is idle and uses the smallest <n> value.
• The ATS0 write command is PIN protected.
• According to "3GPP TS 27.007 (GSM 07.07): AT command set for User Equipment (UE)", ATS0 is also used
as GPRS compatibility command to answer automatically to a network request for PDP context activation
(see Section 11.21). Therefore, when the ATS0 write command is issued with <n> greater than 0, the ME will
attempt to perform a GPRS attach if not yet attached and if configured to do so (due to the setting
AT^SCFG="GPRS/ATS0/withAttach","on").
If the automatic GPRS attach fails the ME keeps trying to attach for approx. 5 minutes, before ATS0 ends up
with "ERROR" or "+CME ERROR: unknown", though the new <n> value takes effect. To avoid the risk of long
response times to ATS0 in such case take care that the parameter AT^SCFG=<gs0aa> is off, if autoanswer
mode is not needed for GPRS or if the mobile works in non-GPRS networks.
The GPRS attach will not be performed on recalling a stored user profile with ATZ or on powerup, even though
a value <n> greater than 0 was stored in the user profile with AT&W.

Set number of seconds to wait for connection completion
ATS7 specifies the number of seconds the TA will wait for the completion of the call setup when answering or
originating a data call. Also referred to as "no answer timeout". To put it plainly, this is the time to wait for the
carrier signal. If no carrier signal is received within the specified time, the TA hangs up.

Notes
• Command ATS7 is only applicable to data calls.
• Values greater than 60 (maximum 255) cause no error, but <n> will be restored to the maximum value of 60.
• The correlation between ATS7 and ATS0 is important. If the called party has specified a high value for
ATS0=<n> call setup may fail.
Example: Call setup may fail if ATS7=30 and ATS0=20.

Command Description
This command is only available during a CSD call or a GPRS connection. The +++ character sequence causes
the TA to cancel the data flow over the AT interface and switch to command mode. This allows you to enter AT
commands while maintaining the data connection to the remote device or, accordingly, the GPRS connection.
To prevent the +++ escape sequence from being misinterpreted as data, it must be preceded and followed by a
pause of at least 1000 ms. The +++ characters must be entered in quick succession, all within 1000 ms.
Notes
• To return from command mode to data or PPP online mode: Enter ATO.
• In Multiplex mode the +++ sequence does not work. Therefore, if required in Multiplex mode, the escape
sequence needs to be implemented in the customer's external Multiplex application. Design solutions, for
example using the DTR signal or a modem status command (MSC), can be found in [7], Section "Escape
Sequence". See also Section 4.10, AT+CMUX.
• On ASC1 the +++ sequence can be used in GPRS connections for switching from PPP online to command
mode.

<alpha>(str)(+CSCS)
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 are displayed. To indicate an overflow, a special character will be used as the 16th character.
This is 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
in early call phases (e.g. for <stat>= ''dialing'', ''incoming'' or ''alerting''), even if a phonebook entry is present
for the number concerned.
Note
• 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.

indicates whether the call has been assigned a traffic channel by the network. A traffic channel is assigned
during call setup after the progress indicator IE has been received and during an active voice connection. This
allows the application to detect whether or not DTMF tones can be transmitted. During a voice connection,
transmission of DTMF tones is possible when parameter <traffic channel assigned> equals "1".
• The additional write command allows to activate Event reporting for the list of current calls. If event reporting
is active for an interface, a call status transition (cf. Call Status Information) and (if desired) the
assignment of a traffic channel will generate an event report indication to this interface. In order to receive
this event report as an URC, the URC presentation mode for this interface has to be configured with
AT+CMER.
The frequency of event report generation can be configured with AT command AT^SCFG. Refer to Call
Status Information for further detail on the configuration options.
• The additional read command allows to determine the event reporting mode <n> which indicates whether the
interface receives event report indications for the list of current calls. Mind that the URC will be displayed only
if the URC presentation mode for the interface concerned has been configured with AT+CMER.

^SLCC:
URC "^SLCC" displays the list of current calls as displayed with the execute command AT^SLCC. The list is dis-
played in the state it has at the time of display, not in the state it had when the signal was generated.
The URC's occurrence indicates call status changes for any of the calls in the list of current calls.
Please refer to Call Status Information and AT^SCFG for further information about the configuration of
this URC.
Event reporting can be enabled separately for each interface. Interface settings are saved with AT&W and can be
displayed with AT&V. Additionally, The URC presentation mode for the interface must be configured with
AT+CMER.
Depending on the value of AT^SCFG setting <sucs>, Indicator "^SLCC" will be issued (if configured with write
command AT^SLCC and AT+CMER)
• when a state transition ends in state "active" or in state "unknown" (if AT^SCFG setting <sucs>="restricted")
• when any state transition (including transitions beginning or ending in state "unknown") occurs in the list of
active calls, or when a traffic channel is established (if AT^SCFG setting <sucs>="verbose").
If multiple displays of identical list configurations occur, this happens because of short intermediate states of the
list, that have already been overridden by new transitions and states. Thus, it is guaranteed that the configuration
displayed is always the current configuration at the time of the last display.
The list of active calls displayed with this URC will always be terminated with an empty line preceded by prefix
"^SLCC: ", in order to indicate the end of the list.
Command Description
The read command returns an indication whether event reporting is active for the current interface.
The exec command returns a list of current calls of ME. If command is successful, but no calls are available, no
information response is sent to TE.
Use the write command to activate or deactivate event reporting for URC "^SLCC". Event reporting can be
enabled separately for each interface. Interface settings are saved with AT&W and can be displayed with AT&V.

7.22 AT^SLCC
<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.
• Depending on the connection state <stat> and the teleservice class, the parameter <traffic channel
assigned> can take the following values:
Voice call in state "Dialing", "Alerting", "Incoming", "Active": 1
Voice call in state "Held": 0
Voice call in state "Waiting": 0
Conference call: 0
Data or fax call in state "Dialing", "Alerting", "Incoming": 1. After CONNECT, in state "Active", <traffic
channel assigned> reverts to 0, because DTMF tones are not permitted in data or fax connections.

8.2 AT+COPS
8.2
AT+COPS Operator Selection
AT+COPS queries the present status of the TC65's network registration and allows to determine whether auto-
matic or manual network selection shall be used. Additional service is available with AT^SOPS.
Three operator selection modes are available:
• Automatic
TC65 searches for the home operator automatically. If successful the TC65 registers to the home network. If
the home network is not found, TC65 goes on searching. If a permitted operator is found, TC65 registers to
this operator.
If no operator is found the TC65 remains unregistered.
• Manual
Desired operator can be determined using the AT+COPS write command. If the operator is found, TC65 reg-
isters to it immediately. If the selected operator is forbidden, the TC65 remains unregistered.
• Manual/automatic
The ME first tries to find the operator determined via AT+COPS write command. If the ME is able to register
to this operator, it enters the manual operator selection mode. If the ME cannot find this operator or fails to
register to this operator, then it enters the automatic operator selection mode and starts to select the home
operators network or another (permitted) one.
The most recently entered operator selection mode is still valid after the ME was restarted (power-off/on).
The AT+COPS test command lists sets of four parameters, each representing an operator present in the network.
A set consists of
• an integer indicating the availability of the operator,
• long alphanumeric format of the operator's name and
• numeric format representation of the operator.
Any of the parameters may be unavailable and will then be an empty field (,,). The list of operators comes in the
following order: Home network, networks referenced in SIM and other networks.
The operator list is followed by a list of the supported <mode>s and <format>s. These lists are delimited from
the operator list by two commas.
If the test command is used during an ongoing GPRS transfer, traffic will be interrupted for up to one minute.
The AT+COPS read command returns the current <mode> and the currently selected operator. If no operator is
selected, <format> and <oper> are omitted.
The AT+COPS write command forces an attempt to select and register to the GSM network operator (see note
below). If the selected operator is not available, no other operator will be selected (except <mode>=4). The
selected operator name <format> will apply to further read commands, too.
Command settings are effective over all serial interfaces of the TC65.

8.2 AT+COPS
Note
• It is not recommended to use the AT+COPS command before passing the CHV (card holder verification) / SIM
PIN1 verification. In case of entering of AT+COPS= 0 before PIN1 verification the module will answer with OK
and does not try to register to the network. Also, the test command should only be used after PIN1 authenti-
cation.

8.3 AT^SOPS
8.3
AT^SOPS Extended Operator Selection
AT^SOPS queries the present status of the TC65's network registration. Since basic operator selection services
are available with AT+COPS this command uses the methods of the Enhanced Operator Name String (EONS)
specification while handling operator name strings. Additional EONS related information is available with
AT^SIND.
AT^SOPS test command lists sets of five parameters, each representing an operator present in the network.
A set consists of
1. an integer indicating the availability of the operator,
2. specification of the source of the operator name <eonsOperator>,
3. operator name according to EONS Table,
4. Service Provider Name from the SIM Service Table and
5. numeric format representation of the operator.
Any of the parameters may be unavailable and will then be an empty field (,,).
The list of operators comes in the following order: Home network, networks referenced in SIM and other net-
works.
After the operator list the TC65 returns lists of supported <mode>s and <format>s. These lists are delimited
from the operator list by two commas.
If the test command is used while an ongoing GPRS transfer, traffic will be interrupted for up to one minute.
Command settings are effective over all serial interfaces of the TC65.

AT+CREG Network registration
The AT+CREG command serves to verify the network registration status of the ME. For this purpose two types of
URCs are available.
The AT+CREG read command returns the URC presentation mode <n> and an integer <stat> that shows the
registration status of the ME. The location information elements <lac> and <ci> are returned only when <n>=2

Not registered, ME is currently not searching for new operator
Normally, status 0 occurs temporarily between two network search phases
(status 2). However, if it persists, one the following reasons may apply:
• Automatic network selection is active, but probably there is
- no SIM card available
- no PIN entered
- no valid Home PLMN entry found on the SIM
• Manual network selection is active and the selected network is available,
but login fails due to one of the following reasons:
-
#11 ... PLMN not allowed
-
#12 ... Location area not allowed
-
#13 ... Roaming not allowed in this location area
In either case, user intervention is required. Yet, emergency calls can be made
if any network is available.
1
Registered to home network
2
Not registered, but ME is currently searching for a new operator
The ME searches for an available network. Failure to log in until after more than
a minute may be due to one of the following reasons:
• No network available or insufficient Rx level.
• The ME has no access rights to the networks available.
• Networks from the SIM list of allowed networks are around, but login fails
due to one of the following reasons:
-
#11 ... PLMN not allowed
-
#12 ... Location area not allowed
-
#13 ... Roaming not allowed in this location area
After this, the search will be resumed (if automatic network search is
enabled).
• The Home PLMN or an allowed PLMN is available, but login is rejected by
the cell (reasons: Access Class or LAC).
If at least one network is available, emergency calls can be made.
3
Registration denied
• Authentication or registration fails after Location Update Reject due to one
of the following reasons:
-
#2 ... IMSI unknown at HLR
-
#3 ... Illegal MS
-
#6 ... Illegal ME
Either the SIM or the MS or the ME are unable to log into any network. No
further attempt is made to search or log into a network. User intervention is
required. Emergency calls can be made, if any network is available.

The AT^SFNUR command specifies the Fixed Network User Rate (FNUR) parameter. This parameter is impor-
tant only for mobile originated 14.4 kbit/s UDI calls (AT+CBST=75) and mobile terminated data calls if the bearer
capability information element is delivered without data bearer service (see AT+CSNS and AT+CBST commands).
Changes are recommended only if a CSD call fails. The choice as to which of the values to use depends on the
GSM network and the location. Users should be aware that even the same operator may apply varying FNUR
configurations in different regions.
The AT^SFNUR command has no effect on CSD connections controlled by the Internet Service commands. If
needed for the Internet Services the Fixed Network User Rate can be set in the connection profile. For details
see AT^SICS, parameter <conParmValue> "fnur".

8.9 AT^MONI
• If the radio cell changes during a connection, the parameters PWR, RXLev and C1 of the 'Serving Cell' part
cannot be updated under certain conditions and therefore, are displayed as "-" (for conditions see also
AT+CREG). This is because the MS does not update the cell selection and reselection parameters since, in
this mode, they are not relevant for operation. When the connection ends, and the mobile is back to IDLE
mode, correct values will be given.
If the radio cell changes during a connection, it normally takes 1 or 2 seconds to update the parameters cell,
NCC and BCC. Until the information is received from the new base station, the default values will be shown
instead: cell="0000", NCC="-", BCC="-".
• If the BS supports frequency hopping during a connection, the dedicated channel (parameter chann) is not
stable. This mode is indicated by chann = 'h'.
• To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving level,
for example, can be queried with both commands. Yet the resulting values may be slightly different, even
though obtained over a time period of a few seconds. This is quite normal and nothing to worry about, as the
cell information is permanently updated.
• For compatibility with earlier products and to support legacy applications, any input character may be used to
stop the output in certain cases (depending on the settings of AT+IPR and AT+CMUX).

the MS or after loss of coverage.
• 'No connection' - The MS is camping on a cell and registered to the network. The service state is 'idle', i.e.
there is no connection established or a dedicated channel in use.
• 'Cell Reselection' - The MS has not yet lost coverage but is searching for a better cell, since the cell reselec-
tion criterion is fulfilled.
• 'Limited Service' - The MS is camping on a cell but not registered to the network. Only emergency calls are
allowed. The MS enters this state, for example, when
- no SIM card is inserted, or PIN has not been given,
- neither Home PLMN nor any other allowed PLMN are found,
- registration request was not answered or denied by the network (use command AT+CREG to query the
registration status),

Notes
• Due to the fact that not all necessary information of the neighbour cells can be decoded during a connection,
there are several constraints to be considered:
- Only neighbour cells that have already been visible in IDLE mode will be further updated, as long as they
are still included in the list.
- Though new neighbour cells can be added to the list (e.g. due to handover), their C1 and C2 parameters
cannot be displayed until the connection is released. In this case "-" is presented for C1 and C2.
- To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving
level, for example, can be queried with both commands. Yet the resulting values may be slightly different,
even though obtained over a time period of a few seconds. This is quite normal and nothing to worry about,
as the cell information is permanently updated.
• For compatibility with earlier products and to support legacy applications, any input character may be used to
stop the output in certain cases (depending on the settings of AT+IPR and AT+CMUX).
• If the ME is Java controlled, periodic retrieval of cell information using the write command
AT^MONP=<period> is not supported. If periodic cell information is required simply repeat the execute com-
mands at regular intervals.

• For compatibility with earlier products and to support legacy applications, often any input character will stop

Notes
• The active settings for omitted parameters are retained without changes.
• Explicit CUG invocation means that at each call setup, CUG information is added to the called number.
• Upon delivery, settings are predefined with
<n>=0,
<index>=10,
<info>=0.
These delivery defaults cannot be recalled automatically.
• When starting a call with ATD, Parameter 'G' or 'g' of command ATD will have no effect if the option selected
for this single call is identical to the option already selected with AT+CCUG.
• Current settings are saved in the ME automatically.
• ATZ or AT&F do not influence the current settings.
• some combinations of parameters may lead to rejection of CUG calls by the network. For more information,

<class> 2 (data) comprises all those <class> values between 16 and 128, that
are supported both by the network and the MS. This means, a setting made for
<class> 2 applies to all remaining data classes (if supported). In addition, you
can assign a different setting to a specific class. For example, you can activate
Call Forwarding for all data classes, but deactivate it for a specific data class.

Notes
• You can register, disable, enable and erase <reason> 4 and 5 as described above. However, querying the
status of <reason> 4 and 5 with AT+CCFC will result in an error ("CME error: Operation not supported"). As
an alternative, you may use the ATD command followed by *'# codes to check the status of these two reasons.
See Star-Hash (*#) Network Commands for a complete list of *# GSM codes. See also examples below.
• Most networks will not permit registration of new parameters for conditional call forwarding (reasons 1,2,3,5)
while unconditional call forwarding is enabled.
• The AT+CCFC command offers a broad range of call forwarding options according to the GSM specifications.

9.6 AT+CCFC
However, when you attempt to set a call forwarding option which is not provisioned or not yet subscribed to,
the setting will not take effect regardless of the response returned. The responses in these cases vary with
the network (for example "OK", "Operation not allowed", "Operation not supported" etc.). To make sure check
the call forwarding status with <mode>=2.
• Some networks may choose to have certain call forwarding condtions permanently enabled (e.g. forwarding
to a mailbox if the mobile is not reachable). In this case, erasure or deactivation of call forwarding for these
conditions will not be successful, even if the CCFC request is answered with response "OK".
• The command has been implemented with the full set of <class> parameters according to GSM 07.07. For
actual applicability of SS "call forwarding" to a specific service or service group (a specific <class> value)
please consult table A.1 of GSM 02.04.
• There is currently no release of GSM standard "GSM 02.04", in which the "Call Forwarding" Supplementary
Service is defined as applicable to SMS services.
Example
Please note that when you configure or query call forwarding without specifying any classes, the settings will
refer to classes 1, 2 and 4 only (=default). The handlingof classes is equivalent to AT+CLCK.
•
To register the destination number for unconditional call forwarding (CFU):
at+ccfc=0,3,"+493012345678",145
OK
The destination number will be registered for voice, data and fax services (default <class> 7).
In most networks, the registration will also cause call forwarding to be activated for these <class> values.
•
To query the status of CFU without specifying <class>:
at+ccfc=0,2
+CCFC: 1,1,"+493012345678",145
+CCFC: 1,2,"+493012345678",145
+CCFC: 1,4,"+493012345678",145
OK
•
To deactivate CFU without specifying <class>:
at+ccfc=0,0
OK
To check whether CFU was successfully deactivated (note that the destination number remains registered in
the network when you disable CFU):
at+ccfc=0,2
+CCFC: 0,1,"+493012345678",145
+CCFC: 0,2,"+493012345678",145
+CCFC: 0,4,"+493012345678",145
OK
•
To erase the registered CFU destination number:
at+ccfc=0,4
OK
Now, when you check the status, no destination number will be indicated:
at+ccfc=0,2
+CCFC: 0,1
+CCFC: 0,2
+CCFC: 0,4

URC 1
Indication of a call that is currently waiting and can be accepted.
+CCWA: <calling number>, <type of number>, <class>, , <CLI validity>
If <n>=1 and the call waiting supplementary service is enabled in the network, URC "+CCWA" indicates a wait-
ing call to the TE. It appears while the waiting call is still ringing.
URC 2
Indication of a call that has been waiting.
^SCWA
If <n>=1 and the call waiting supplementary service is enabled in the network, this URC indicates that a wait-
ing call rang when the ME was in online mode during a CSD call, but the calling party hung up before the ME
went back to command mode.

Notes
•
If the active call is a CSD call, and a waiting call is received, then the ME produces a BREAK while still in
online mode, and displays
- the +CCWA URC (as above) when the ME goes back to command mode while the waiting call is still active
and can be accepted;
- or the ^SCWA URC (as above) when the ME goes back to command mode after the waiting call has
ended.
•
With the AT+CHLD command, it is possible to establish a multiparty call or to set the active voice call on hold
and then accept a waiting voice call (not possible with fax and data call). See also AT+CHLD
•
Users should be aware that if call waiting is activated (<mode>=1), the presentation of URCs needs to be
enabled, too (<n>=1).
Otherwise, on the one hand, a waiting caller would be kept waiting due to lack of BUSY signals, while, on the
other hand, the waiting call would not be indicated to the called party.
•
The AT+CCWA command offers a broad range of options according to the GSM specifications. However,
when you attempt to enable call waiting for a <class> for which the service is not provisioned or not sup-
ported , the setting will not take effect regardless of the response returned. The responses in these cases vary
with the network (for example "OK", "Operation not allowed", "Operation not supported" etc.). To make sure
check the current call waiting settings with <mode>=2.
•
The AT+CCWA command has been implemented with the full set of <class> parameters according to
GSM 07.07. For actual applicability of SS call waiting to a specific service or service group (a specific
<class> value) please consult table A.1 of GSM 02.04
•
Despite the specifications stated in GSM 02.04 call waiting is not handled uniformly among all networks:
GSM 02.04, Annex A, provides the following specification:
"The applicability of call waiting refers to the telecommunication service of the active call and not of the waiting
call. The incoming, waiting, call may be of any kind." Nevertheless, networks do differ on the actual imple-
mentation of the service. For example, the activation of call waiting for <class> 4, "fax", causes some net-
works to send a call waiting indication if a call "of any kind" comes in during an active fax call, but others may
(with the same settings active) indicate a waiting fax call during any kind of active call. Thus, the only reliable
way to receive or prevent a call waiting indication under any circumstances and in any network, is to activate
or deactivate call waiting for all tele- and bearer services (<class> 255).

Command Description
TA controls the Supplementary Services Call Hold and Multiparty. Calls can be put on hold, recovered, released,
and added to a conversation.
Like for all Supplementary Services, the availability and detailed functionality of Call Hold and Multiparty services
depends on the configuration of the GSM network. The TC65 can only request the service, but the network
decides whether and how the request will be answered.
Parameter Description
<n>(num)
0
Release all held calls or set User Determined User Busy (UDUB) for a waiting
call:
• If a call is waiting, release the waiting call. The calling party will receive a
"BUSY" indication (Supplementary Service User Determined User Busy
"UDUB")
• Otherwise, terminate all held calls (if any).
1
Terminate all active calls (if any) and accept "the other call" as the active call:
• If a call is waiting, the waiting call will be accepted.
• Otherwise, if a held call is present, the held call becomes active.
1X
Terminate a specific call X (X= 1-7). The call may be active, held or waiting.
The remote party of the terminated call will receive a "NO CARRIER" indica-
tion. Parameter X is the call number <idx> of the targeted call in the list of cur-
rent calls available with AT command AT+CLCC.
2
Place all active calls on hold (if any) and accept "the other call" as the active
call:
• If a call is waiting, the waiting call will be accepted.
• Otherwise, if a held call is present, the held call becomes active.
2X
Place all active calls except call X (X= 1-7) on hold. Parameter X is the call
number <idx> of the targeted call in the list of current calls available with AT
command AT+CLCC.
3
Add a held call to the active calls in order to set up a conference (multiparty)
call.
