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.

Note

• To return from command mode to data or PPP online mode: Enter ATO.

AT+CBST Select bearer service type

The AT+CBST write command selects the bearer service <name>, the data rate <speed> and the connection

element <ce> to be used when data calls are originated. The settings also apply to mobile terminated data calls,

especially when single numbering scheme calls or calls from analog devices are received (see AT+CSNS). See

GSM 02.02[1] for a list of allowed combinations of subparameters.

<alpha>^(str)(+CSCS)

Alphanumeric representation of <number> corresponding to the entry found in phonebook.

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.

7.23

AT^SLCC Extended list of current calls

AT^SLCC covers essentially the same information as GSM 07.07 command AT+CLCC, with the following exten-

sions:

• The execute command response contains the additional parameter <traffic channel assigned> which

indicates whether the call has been assigned a traffic channel by the network and transmission of DTMF

tones is possible.

• 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. Interface settings are saved with AT&W and can be displayed with AT&V

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 returns an indication whether event reporting is active for the current interface.

Mind that the URC will be displayed only if the URC presentation mode for the interface concerned has been

configured with AT+CMER.

• The exec command returns, like AT+CLCC, a list of current calls. If the command is successful, but no calls

are available, no information response is sent to the TE.

^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.

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 the AT+CHLD command, 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.

• If a multiparty call is established, the transmission of DTMF tones is not possible anymore till the call is

released. This behaviour is caused due to an ambiguity between the different transaction identifiers.

8.2

AT+COPS Operator Selection

AT+COPS queries the present status of the TC65i'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

TC65i searches for the home operator automatically. If successful the TC65i registers to the home network.

If the home network is not found, TC65i goes on searching. If a permitted operator is found, TC65i registers

to this operator.

If no operator is found the TC65i remains unregistered.

• Manual

Desired operator can be determined using the AT+COPS write command. If the operator is found, TC65i reg-

isters to it immediately. If the selected operator is forbidden, the TC65i 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

operators network or another (permitted) one. If the ME is registered and the manually selected network is

not available, the ME will remain registered without further result code notification.

The most recently entered operator selection mode is still valid after the ME was restarted (power-off/on).

The AT+COPS test command conists of several parameter sets, each representing an operator present in the

network.

Each set contains the following information:

• 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 TC65i.

Automatic mode; <oper> field is ignored.

Manual operator selection

Write command requires <oper> in numeric format, i.e. <format> shall be 2.

Read command returns the current <mode> and the currently selected

<oper>. If no operator is selected, <format> and <oper> are omitted.

Manually deregister from network and remain unregistered until <mode>=0 or

1 or 4 is selected.

Set only <format> (for AT+COPS read command).

Automatic / manual selection; if manual selection fails, automatic mode

(<mode>=0) is entered (<oper> field will be present).

<format>^{(num)(&W)(&V)}

0^(&F)

Long alphanumeric format of <oper>. Can be up to 26 characters long.

Numeric format of <oper>. This is the GSM Location Area Identification (LAI)

number, which consists of the 3-digit Mobile Country Code (MCC) plus the 2-

or 3-digit Mobile Network Code (MNC).

Notes

• 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.

• It's possible to apply a 5- or 6-digit LAI for numeric format of <oper> parameter. Please use the correct 2- or

3-digit Mobile Network Code. Otherwise an unintended PLMN could be selected.

• It is not recommended to use the AT+COPS write and test command while TC65i is searching for a new oper-

ator. In this case the module will answer with ERROR. Please use AT+CREG to verify the network registration

status.

8.3

AT^SOPS Extended Operator Selection

AT^SOPS queries the present status of the TC65i'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 TC65i 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 TC65i.

case the module will answer with ERROR. Please use AT+CREG to verify the network registration status.

8.4

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

and ME is registered to the network.

<stat>^(num)(&V)

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.

Registered to home network

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.

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.

• During a connection, not all of the neighbour cell information can be decoded. The following restrictions apply:

- Information is updated only for neighbour cells that have already been visible at connection setup, and

continue to be included in the list of cells.

- New neighbour cells added to the list, for example after handover, cannot be displayed until the connection

AT^SFNUR Select the fixed network user rate

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".

return on a screen. However, this is not part of the response.

• If the ME is Java controlled, periodic retrieval of cell information using the write command

AT^MONI=<period> is not supported. If periodic cell information is required simply repeat the execute com-

mands at regular intervals.

• The parameters LAC and cell are presented as hexadecimal digits, the remaining parameters are composed

of decimal digits.

• 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.

• 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

• 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).

• '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
