List of AT Commands for Nokia 22

INTRODUCTION

This document describes the AT commands that can be used to operate the Nokia 22 PBX

connectivity terminal. Other specifications on the terminal can be found in the Nokia 22 User's

Guide and Nokia 22 Operator's Guide.

All the mandatory and optional ITU-T V.25ter /1/, ETS GSM 07.07 /2/, and ETS GSM 07.05 /3/

commands that are applicable to the Nokia 22 are included in the Nokia 22 command set. The 'de

facto' commands that are widely used with modems are also supported. Note that the ITU-T

V.25ter is a combination of three TIA standards (TIA-602, TIA-615, IS-131).

The Nokia 22 can be used as an adapter for a Group 3 facsimile terminal that supports facsimile

Service Classes 1, 2 and 2.0. The supported facsimile AT commands are listed according to the

standards in which they are specified: Service Class 1 TIA-578-A /4/, Service Class 2.0 TIA-592 /5/

and Service Class 2 TIA SP-2388 /6/. TIA SP-2388 is a draft of a coming standard, but here it is

referred to as a public standard.

The Nokia 22 can be operated using a compatible computer or other devices with a 9-pin RS232

connector.

DATA CONNECTIONS

The Nokia 22 supports non-transparent and transparent data connections and High Speed Circuit

Switched Data (HSCSD) in non-transparent mode, which enables a higher data transfer rate. Time

slot usage is presented as the number of up and down links. The Nokia 22 data transfer modes are

presented in Table 1.

AT COMMAND SYNTAX

For basic information on the AT command syntax, refer to section V.25ter and to the GSM 07.07

section 4. This chapter describes the three different AT command formats and the default value

mechanisms for their parameters.

3.1 Register commands

Table 2. Register command format in command

description subsections

Command

Sn=<n>

Sn?

Response

<n> values

x..y (default z)

xxx..yyy

Set

Read

<n>

The register command factory default value (&F) is given in parentheses under the column ‘<n>

values’. The existence of a register command can be queried by giving a command without equal

or question marks (i.e. ATS3 returns OK, but it does not change the <n> setting). <n> cannot be

omitted when its value is set (i.e. ATS3= returns ERROR).

3.1.1 Basic commands

Table 3. Basic command format in command description

subsections

Command

CMD[x]

CMDy

Description

for value x

for value y

Set/execute

The commands D (dial), A (answer) and O (return to online data state) include also columns for

possible result codes.

The basic command (no ‘+’ prefix) &F default value is underlined. If no value is underlined, the

setting of that command is not stored in the non-volatile memory (the command &Y is an

exception). If the command parameter is in brackets (usually zero), the parameter can be omitted.

3.1.2 Extended commands

Table 4. Extended command format in command description subsections

Command

+CMD[=<x>,...]

+CMD?

+CMD=?

[+CMD: <y>,...]

+CMD: <z>[,...]

[+CMD: ...]

[x,...]

[x]

The extended command (‘+’ prefix) parameter default values are given in a separate column. If the

default value is not in brackets, the default value is the &F default value of the corresponding

parameter. When such a parameter is omitted from a command, its value remains the same as

before. If the default value is in brackets, this value shall be used when the parameter is omitted

List of AT Commands for Nokia 22

from the command line. The setting of such a parameter is not stored in the memory. If a

parameter has no default value, it must always be given.

NOTE: Voice (+V) and fax (+F) commands do not exactly follow this format.

GSM commands can also return a +CME ERROR or +CMS ERROR final result code, when the

error is related to the ME or network functionality. The last column indicates whether these codes

can be returned. The presentation of +CME ERROR can be controlled with the +CMEE command.

List of AT Commands for Nokia 22

TE-TA INTERFACE COMMANDS

4.1 V.25ter

4.1.1 S3 Command line termination character

Command

S3=<n>

S3?

Response

<n> values

0..127 (default 13)

000..127

Set

Read

<n>

The S3 command sets the decimal IA5 value of command line termination used by the DCE as a

part of the header, trailer, and terminator for result codes and information text, along with the S4

parameter (see the description of the V command for usage).

If the value of S3 is changed on a command line, the result code issued in response to that

command line will use the new value of S3. For example, if S3 was previously set to 13 and the

command line “ATS3=50” is issued, the result code issued will use the character with the ordinal

value 50 (IA5 3/2) in place of the CR.

4.1.2 S4 Response formatting character

Command

S4=<n>

S4?

Response

<n> values

0..127 (default 10)

000..127

Set

Read

<n>

The S4 command sets the decimal IA5 value of the character generated by the DCE as a part of

the header, trailer, and terminator for result codes and information text, along with the S3

parameter (see the description of the V command for usage).

If the value of S4 is changed in a command line, the result code issued in response to that

command line will use the new value of S4.

4.1.3 S5 Command line editing character

Command

S5=<n>

S5?

response

<n> values

0..127 (default 8)

000..127

Set

Read

<n>

The S5 command sets the decimal IA5 value of the character recognised by the DCE as a request

to delete the immediately preceding character from the command line.

List of AT Commands for Nokia 22

4.1.4 E Command echo

Command

E[0]

Description

no echo

echo

Set

The E command determines whether or not the DCE echoes characters received from the DTE

during the command state and the online command state.

4.1.5 Q Result code suppression

Command

Q[0]

Description

transmit codes

suppress codes

Set

The Q command determines whether the DCE transmits result codes to the DTE. When result

codes are being suppressed, no portion of any intermediate, final, or unsolicited result code –

header, result text, line terminator, or trailer – is transmitted. Information text transmitted in

response to commands is not affected by this command.

4.1.6 V DCE response format

Command

Description

Set

V[0]

numeric V.25ter basic syntax result codes, limited headers and

trailers

Verbal V.25ter basic syntax result codes, full headers and trailers

The V command determines the contents of the header and trailer transmitted with result codes

and information responses. It also determines whether the result codes are transmitted in numeric

or verbal format. The text portion of information responses is not affected by this setting. The

command S3 and S4 settings affect header and trailer formatting. Note that the result codes

defined in GSM 07.07 and 07.05 have only verbal values.

4.1.7 X Result code selection and call progress monitoring control

Command

Description

Set

X[0]

OK, CONNECT, RING, NO CARRIER, ERROR codes enabled

also CONNECT 1200, CONNECT 2400 enabled

same as value 1

also BUSY enabled

also NO ANSWER enabled

also CONNECT 4800 (or higher data rates), CARRIER, DELAYED, BLACKLISTED enabled

The X command defines the call progress result codes that are sent from the Nokia 22 to the DTE.

When BUSY, NO ANSWER, DELAYED or BLACKLISTED are not enabled, NO CARRIER is used

instead. When CONNECT <rate> with a correct data <rate> is not enabled, CONNECT is used

instead. This command only affects the presentation of the result codes mentioned in this table.

The &C command determines how the state of the circuit 109 relates to the detection of a received

line signal from the distant end. Changing the parameter will take effect immediately in both

command and online command states.

In the &C1 mode of operation, the circuit 109 is on during the connection. The circuit 109 is also

known as a DCD or carrier signal.

4.1.9 &D Circuit 108 (data terminal ready) behaviour

Command

&D[0]

&D1

Description

DTR on->off ignored

DTR on->off causes transition to on-line command state if a call is in progress

DTR on->off causes hang-up

Set

&D2

&D3

DTR on->off causes hang-up and performs reset, like Z

The &D command determines how the DCE responds when the circuit 108/2 is changed from ON

to OFF during the online data state. The circuit 108 is also known as DTR signal.

4.1.10 +IPR Fixed DTE rate

(0,(0,4,5)),(1,(0-2))

This command is used to set the preferred ME power class for each supported GSM frequency

band. The interaction of this setting with the selected bearer service (+CBST and HSCSD

commands) is manufacturer specific (for example, selecting a multislot operation might reduce the

power class automatically). If the setting fails in an ME error, the +CME ERROR: <err> is returned.

The read command returns the currently selected output power class and default output power

class for each supported frequency band (as defined by the ME manufacturer). The parameter

<band1> and its associated power class parameters refer to the currently used frequency band.

For example, +CPWC: 2,1,1,5,4,0 in the case of a dual-band ME currently using the band

GSM1800, for which the power class is currently set to 2, the default being class 1, and the

currently set power class value for GSM900 is class 5, the default being class 4.

The test command returns the supported bands and their power classes. For example,

+CPWC: (0,(0,4,5)),(1,(0-2)) in a case of a dual-band handheld ME.

The +CNMI command defines the procedure for indicating the receiving of new messages from the

network to the TE when the TE is active, e.g. DTR signal is ON. If the TE is inactive (e.g. DTR

signal is OFF), message receiving should be done as specified in GSM 03.38.

<mode> controls the processing of unsolicited result codes specified within this command, <mt>

sets the result code indication routing for SMS-DELIVERs, <bm> for CBMs and <ds> for SMS-

STATUS-REPORTs. <bfr> defines the handling method for buffered result codes when <mode> 1

or 2 is enabled.

The test command gives the supported setting values.

<mode> the setting affects only to unsolicited result codes specified within this command:

Buffer unsolicited result codes in the Nokia 22. If the Nokia 22 result code buffer is

full, the oldest indications will be discarded and replaced with the new received

indications.

Discard indication and reject new received message unsolicited result codes when

the control link is reserved (e.g. in on-line data mode). Otherwise forward them

directly to the TE.

Buffer unsolicited result codes in the Nokia 22 when the control link is reserved (e.g.

in the on-line data mode) and flush them to the TE after reservation. Otherwise

forward them directly to the TE.

NOTE: The result code buffer is in the volatile memory, messages may get lost if the

Nokia 22 is switched off before the codes are sent to TE.

<mt>

The rules for storing received SMs depend on its data coding scheme (refer to GSM

03.38), preferred memory storage (+CPMS) setting, and this value:

No SMS-DELIVER indications are routed to the TE.

If SMS-DELIVER is stored into the Nokia 22, an indication of the memory location is

routed to the TE using an unsolicited result code: +CMTI: <mem>,<index>

SMS-DELIVERs (except for class 2 messages and messages in the message waiting

indication group (store message)) are routed directly to the TE using an unsolicited

result code:

+CMT: <length><CR><LF><pdu> (PDU mode enabled)

the command Show Text Mode Parameters +CSDH)

Class 2 messages and messages in the message waiting indication

group (store message) result in an indication as defined in <mt>=1.

Class 3 SMS-DELIVERs are routed directly to the TE using unsolicited result codes

defined in <mt>=2. The messages of other data coding schemes result in an

indication as defined in <mt>=1.

<bm> the rules for storing received CBMs depend on its data coding scheme (refer

GSM 03.38), the setting of the Select CBM Types (+CSCB), and this value:

No CBM indications are routed to the TE.
