1 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.

3 AT COM MAND 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 Response <n> values Set Read

Sn=<n> x..y (default z)

Sn? <n> xxx..yyy

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 Description

Set/execute

CMD[x] for value x CMDy for value y

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 Response Default +cme error/+cms

error Set/execute Read Test

+CMD[=<x>,...] [+CMD: <y>,...] [x,...] [x] +CMD? +CMD: <z>[,...] [x] +CMD=? [+CMD: ...] [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

4 TE-TA INTERFACE COMMANDS

4.1 V.25ter

4.1.1 S3 Command line termination character

Command Response <n> values Set Read

S3=<n> 0..127 (default 13)

S3? <n> 000..127

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 Response <n> values Set Read

S4=<n> 0..127 (default 10)

S4? <n> 000..127

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 response <n> values Set Read

S5=<n> 0..127 (default 8)

S5? <n> 000..127

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 Description Set

E[0] no echo

E1 echo

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 Description Set

Q[0]

Q1 suppress codes

transmit codes

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 tr ansmitt ed 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

V1 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

X1 also CONNECT 1200, CONNECT 2400 enabled

X2 same as value 1

X3 also BUSY enabled

X4 also NO ANSWER enabled

X5 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.

List of AT Commands for Nokia 22

4.1.8 &C Circuit 109 (received line signal detector) behaviour

Command Description Set

&C[0] always on

&C1 normal operation

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 Description Set

&D[0] DTR on->off ignored

&D1 DTR on->off causes transition to on-line command state if a call is in progress

&D2 DTR on->off causes hang-up

&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

Command Response Default Set Read Test

+IPR=<rate> 0

+IPR? +IPR: <rate>

+IPR=? +IPR: (0),(9600,14400,19200,28800,38400,57600,115200)

The +IPR command sets the data rate at which the DCE will accept commands. The specified rate takes effect immediately following the issuance of the current command line. NOTE: The reset commands Z and &F do not change this setting.

Defined values

<rate> is the bit transmission rate in one second

List of AT Commands for Nokia 22

4.1.11 +ICF DTE-DCE character framing

Command Response Default Set Read Test

+ICF=<format>,<parity> [3,3]

+ICF? +ICF: <format>,<parity>

+ICF=? +ICF: (3,5),(0-3)

The +ICF command is used to determine the local serial port start-stop character framing that the Nokia 22 uses when accepting DTE commands and when transmitting information text and a result. NOTE: The reset commands Z and &F do not change this setting.

Defined values

<format> determines the number of bits in the data bits, the presence of a parity bit, and the number of stop bits in the start-stop frame.

3 8 data, 1 stop 5 7 data, 1 parity, 1 stop

<parity> determines how the parity bit is generated and checked, if present. 0 odd

1even 2mark 3 space

4.1.12 +IFC DTE-DCE local flow control

Command Response Default Set Read Test

+IFC=<dce-by-dte>,<dte-by-dce> 2,2

+IFC? +IFC: <dce-by-dte>,<dte-by-dce>

+IFC=? +IFC: (0-3),(0-2)

The +IFC controls the operation of a local flow control between the DTE and the Nokia 22.

Defined values

<dce-by-dte> specifies the method to be used by the DTE to control the flow of the received data from the Nokia 22

<dte-by-dce> specifies the method to be used by the Nokia 22 to control the flow of the transmitted data from the DTE
