Introduction

The Westermo ID-90 is an industrialised ISDN Terminal adapter. This Terminal adapter has been developed with high speed industrial data communications in mind and has some features you would not expect to find on normal adapters.

The unit is DIN rail mounted and has both an RS-232/V.24 and RS-485 interface in 2 or 4 wire connections. Terminal data rates of up to 115.2 kbit/sec can be handled with a 128 kbit/s ISDN B-channel bit rate. The ID-90 has been designed to meet the European ISDN standard DSS1 as well as French VN4. All standard ISDN transport protocols are supported including HDLC transparent, X75, PPP and ML-PPP. V.110 asyncronous is supported with flow control at data rates up to 19.2 kbit/sec.

A watchdog facility continually monitors the power supply and internal hardware as well as the operational software. In the event of a problem the modem automatically resets. This feature has been included to make the unit more suitable for use in unmanned locations.

The ID-90 is available in two standard versions: One for high input voltages, version HV with nominal voltage range 95–240V AC and 110–240V DC ±10%. One low voltage version, version LV with nominal input voltages 12–45V AC and 12–55V DC ±10%.

The ID-90 has 4 Alarm inputs that can be used to trigger 20 character SMS paging messages or establish automatic data connections, making the unit ideal for alarm monitoring and remote diagnostics. The ID-90 features DIP-switch configuration and can be programmed using AT-commands, and a Configurator for local as well as remote configuration and CAPI 2.0 compatibility.

The ID-90 is also available in an optional configuration with an internal analogue V90 modem enabling connections from ISDN to analogue modem end locations.

The ID-90 has been designed with the engineer in mind, hence the extensive information on the command set, S registers, DIP-switches and error codes. We have endeavoured to include all necessary information however if you need more please do not hesitate to call us.

Safety

This equipment should only be installed by professional service personnel. If the unit is intended for permanent connection to mains supply, there should be a readily accessible disconnect device (circuit breaker) incorporated into the fixed wiring. The ID-90 ISDN S0 is compliant to the requirement for TNV1 circuits for connection to Telecommunication networks. The mains connection is classified as hazardous voltage and the ID-90 classified as a Class I equipment. The supply voltage to the Alarm input must use a SELV classified voltage source. The RS-232/V.24 and RS-485 interface must only be connected to SELV circuits. Description of the above classifications are given in SS-EN 60950 Issue 5. The mains input is protected with a 1A, 250V time lag fuse. The fuse must only be replaced with the same type and rating. Wickman type no: 19372 1A/250V or Littelfuse

Installation

The Terminal Adapter should be connected in the following way: Power connection is made through screw-block at bottom right corner. For HV-version a 3-pole connector, and for LV-version a 2-pole connector is used.

Computers or other equipment are connected through an RS-232/V.24 or RS-485 connection. The RS-232/V.24 uses a 9-pole D-sub and the RS-485 a 9-pole screw connector. Do not use ribbon cable for RS-232/V.24 connections.

Typical S0-bus connections

The Terminal equipment TE/TA like the ID-90 Terminal adapter can be connected to the NT in 3 different ways always with a terminating resistor TR in each end of the bus, TR should in all three cases be 100 ohm:

• Point to Point. In this configuration the ID-90 is the only TA on the S0bus. A distance d1 of 1000 m is generally archived with a 0.3 mm

40 nF/km cable.

• Short Passive Bus. The short passive bus puts no restriction on the distance between units, but only specifying the maximum round trip delay to be 10 to 14 µs giving a d1 of 100 to 200 m depending on the cable impedance. Up to 8 ID-90 in combination with other terminal equipment can be connected to the S0bus with a maximum connection length d2 = 10 m.

• Extended Passive Bus. The difference between the short passive bus and the extended passive bus is that the extended passive bus specifies a distance between the units, d3 and that the units are located at the far end from the NT at a distance of d3 from the far end terminating resistor TR. The range of d3 is from 25 to 50 m giving at least d1 =500 m. (d2 see Short Passive Bus).

Alarm inputs

The four alarm inputs are accessed through screw terminals, the alarm inputs are opto-isolated from all other parts of the ID-90. The alarm inputs need an external supply voltage of 10–60V DC to be operated. The supply is connected between the alarm input common and the four inputs via making or breaking contacts. The inputs is not polarity sensitive but all inputs must use the same common. The alarm inputs can use any mix of making and breaking contacts as the alarm trigger condition is programmable through AT-commands.

Example 1

Alarm through relay contacts.

Example 2

Alarm from a PLC with open collector.

AT command set

All parameter can be changed by using an extended AT command set described in this chapter.

Please check if the factory setting will fit with your environment. The factory setting is

described (highlighted) in the parameter list shown in chapter “AT command set” (see below).

If you want another configuration as set in the factory default setting, please do the following steps:

• Connect the ID-90 to ISDN interface

• Connect the PC’s com-port to the DTE interface of the ID-90.

• Connect the power supply to the mains socket.

• Start a terminal emulation on your PC, please verify that the baudrate setting of the terminal emulation fits those of the ID-90.

• Set up the parameter of the ID-90 from the terminal emulation and save the parameter using the AT command set.

Example: To change the used B channel protocol to X.75 please enter the following commands:

ATB10<↵> (set protocol to X.75) AT&W<↵> (save the new configuration)

• Leave your terminal emulation and start your application program.

With the exception of the command A/ (Repeat command) all commands begin with the prefix AT and AT!, where the prefix AT! is used to identify commands to the analogue V90 option. Commands are terminated with <CR>. Corrections in a command line are done with <BACKSPACE>. A command line has a maximum of 80 characters. The command line is automatically cancelled by longer input. Blanks are ignored, capital/small letters are not significant.

The parameter settings of the ID-90 obtained when using the AT commands can be permanently stored (AT&W) and are not lost by resetting or by leaving the AT command mode.

To enter the AT command mode during an active data connection you must use the following sequence (“Escape sequence”):

at least 1 sec pause <+><+><+> 1 sec pause

The time gap between all three plus signs may not exceed 1 sec. The escape sequence is transmitted transparent to the remote device.

A/ – Repeat last command line

This command repeats the commands of the last entered command line.

Note: No prefix AT is required.

##An – Only analogue outgoing call (only ID-90V90)

Can enable the adapter to make analogue calls even if no control character (’#’ or ’!’) is used in the dial string. This also implies that no digital outgoing call can be made when AT##A1 is set. Digital incoming calls can still be received.

AT##A0: configures the adapter to be able to make both analogue and digital

outgoing calls. (default)

AT##A1: configures the adapter only to make analogue outgoing calls.

A – Accept incoming call

Using this command you can accept an incoming call, if automatic call acceptance is not set (Register S0 = 0). An incoming call is displayed by the message “RING” or the code “2”. Must be the last command in an AT command line.

ATA[//<UUS1data>] UUS1data transmitted data with UUS1 signalling

B – B channel protocol

Transmission protocol for data communication in the B channel.

ATB0: V.110 asynchronous (For file and data transfer i.e.

236607-2204

%B – Set local baudrate

Sets the local baudrate of the ID-90 to the desired value (fix value) or to autodetection. When autodetection is set, the ID-90 will recognize the desired baudrate with every newly entered AT command by the terminal equipment (PC). With all other settings the PC must use the same baudrate. Must be the last command in an AT command line.

AT%B0 Automatic local baudrate detection enabled (autobauding, default) AT%B1 Local baudrate set to 1 200 bit/s AT%B2 Local baudrate set to 2 400 bit/s AT%B3 Local baudrate set to 4 800 bit/s AT%B4 Local baudrate set to 9 600 bit/s AT%B5 Local baudrate set to 19 200 bit/s AT%B6 Local baudrate set to 38 400 bit/s AT%B7 Local baudrate set to 57 600 bit/s AT%B8 Local baudrate set to 115 200 bit/s

Note: Autobauding (AT%B = 0) is available for AT command set only. If autobauding is

set and cmds is changed to PAD, br will be set to 4 (9 600 bit/s).

CONF – Enter TA+Configurator

Enters directly into the TA+Configurator, the configuration prompt “#” will be displayed. Leave the TA+Configurator with the command “quit”.

ATCONF

AT#C

#C1=hbhb – Select bearer service outgoing

Selects the bearer service that will be sent with an outgoing call The value for hbhb (word) is the CIP value as defined in the CAPI 2.0 specification (default 0002).

Example: an outgoing call as a voice call: AT#C1=0004.

24 6607-2204

#C2=hbhbhbhb – Select bearer service incoming

Selects the bearer services that can be accepted with an incoming call. The definition of hbhbhbhb (double word) is the CIP mask as defined in the CAPI 2.0 specification (default 00010016).

Example: AT#C2=00010016: Accept analogue incoming calls

AT#C2=00000001: Accept all incoming calls.

Note: Before issuing an outgoing call the command AT#C1 has to be set.

To use the predefined services please setup factory defaults (AT&F).

!%C – Enable/Disable Data Compression

Enables or disables data compression negotiation. The modem can only perform data compression on an error corrected link. The parameter value, if valid, is written to S41 bits 0 and 1.

AT!%C<value>

0 Disables data compression. Resets S46 bit 1. 1 Enables MNP 5 data compression negotiation. Resets S46 bit 1. 2 Enables V.42 bis data compression. Sets S46 bit 1. 3 Enables both V.42 bis and MNP 5 data compression. Sets S46 bit 1. (default)

256607-2204

D – Initiate outgoing call

Dials the number (D for Dial). The dial modifier “W", “>”, “T”, “;”, “@” can be freely inserted in the dial string; they have no influence on the dial procedure of the ID-90. Must be the last command in AT command line. Any character input while the ID-90 is dialing will cancel the dialing procedure.

Notes: – To setup the own subaddress see configuration command sub.

– Adding an “e” to CALLEDnumber indicates that a connection to the internal

remote access of a ID-90 shall be performed, the protocol X.75 (ATB10) has to be used.

26 6607-2204

&D – DTR control

Selects the behaviour of the ID-90, when the DTE control line DTR changes from ON to OFF.

AT&D0 DTR is evaluated: ignored AT&D2 DTR is evaluated: dropping the DTR line by the DTE will disconnect

an existing ISDN connection. An incoming call will accepted only with DTR active. (default)

AT&D4 DTR is evaluated: Incoming calls will be accepted independent of

DTR status; DTR drop disconnects an active connection

!+DS – Data Compression

This extended-format compound parameter controls the V.42bis data compression function if provided in the modem. It accepts four numeric subparameters:

AT!+DS=[<direction>[,<compr_neg>[,<max_dict>[,<max_string>]]]]

<direction> Specifies the desired direction(s) of operation of the data compres-

sion function; from the DTE point of view. 0 Negotiated; no compression (V.42bis P0=0). 3 both directions, accept any direction (V.42bis P0=11). (default)

<compr_neg> Specifies whether or not the modem should continue to operate if the

desired result is not obtained. 0 Do not disconnect if V.42bis is not negotiated by the remote

modem as specified in <direction>

<max_dict> Specifies the maximum number of dictionary entries (2 048 entries)

which should be negotiated (may be used by the DTE to limit the codeword size transmitted, based on its knowledge of the nature of the data to be transmitted).

<max_string> Specifies the maximum string length (32 bytes) to be negotiated

(V.42bis P2).

Reporting Current or Selected Values

276607-2204

E – Local echo

Selects the local echo in command mode.

ATE0 No local echo ATE1 Local echo on in command phase (default)

!%E – Enable/Disable Line Quality Monitor

and Auto-Retrain or Fallback/Fall Forward

Controls whether or not the modem will automatically monitor the line quality and request a retrain (%E1) or fall back when line quality is insufficient or fall forward when line quality is sufficient (%E2). The parameter value, if valid, is written to S41 bits 2 and 6. If enabled, the modem attempts to retrain for a maximum of 30 seconds.

AT!%E0 Disable line quality monitor and auto-retrain. AT!%E1 Enable line quality monitor and auto-retrain.

AT!%E2 Enable line quality monitor and fallback/fall forward.

Fallback/Fall Forward. When %E2 is active, the modem monitors the line quality

(EQM). When line quality is insufficient, the modem will initiate a rate renegotiation to a lower speed within the V.34/V.32 bis/V.32 modulation speeds. The modem will keep falling back within the current modulation if necessary until the speed reaches 2 400 bit/s (V.34) or 4 800 bit/s (V.32). Below this rate, the modem will only do retrains if EQM thresholds are exceeded. If the EQM is sufficient for at least one minute, the modem will initiate a rate renegotiation to a higher speed within the current modulation speeds. The rate renegotiations will be done without a retrain if a V.32 bis connection is established. Speeds attempted during fallback/fall forward are those shown to be available in the rate sequences exchanged during the initial connection. Fallback/fall forward is available in error correction and normal modes, but not in direct mode.

28 6607-2204

!+ES – Error Control

S0 – Number of Rings to Auto-Answer

S0 sets the number of the rings required before the modem automatically answers a call. Setting this parameter to zero disables auto-answer mode.

0 No automatic call acceptance, acceptance of an incoming call is controlled

by the data terminal (command ATA after RING)

1 Immediate call acceptance by the terminal adapter (default)

2..n Call acceptance through the terminal adapter after n “RING” messages.

Note: The time between two ring messages can be configured using the

ID-90-configuration command “ringtimer“ (default = 5 sec.)

S1 – Ring Counter

Ring Counter (read only), S1 is incremented each time the modem detects a ring signal.

S2 – Escape Character

S2 holds the decimal value of the ASCII character used as the escape character. The default value 43 corresponds to an ASCII '+'..

S3 – Carriage Return Character

S3 sets the command line and result code terminator character. Default: 13 Carriage Return

S4 – Line Feed Character

S4 sets the character recognised as a line feed. The Line Feed control character is output after the Carriage Return control character if verbose result codes are used. Default: 10 Line Feed.

S5 – Backspace Character

S5 sets the character recognised as a backspace. The terminal adapter will not recognise the Backspace character if it is set to a value that is greater than 128 ASCII. This character can be used to edit a command line. When the echo command is enabled, the modem echoes back to the local DTE the Backspace character, an ASCII space character and a second Backspace character; this means a total of three characters are transmitted each time the modem processes the Backspace character. Default: 8 (Backspace)

S6 – Dial delay

This S-register defines how many seconds the unit will delay a call attempt. The timer starts counting after the ATD command has been sent to the adapter.

S7 – Wait time for Carrier

S7 sets the time the terminal adapter will wait for synchronization and also the time the analogue modem will wait for carrier. Default: 50 sec

42 6607-2204

S9 – Enable PNP functionality for Windows

S9 enables and disables the Windows Plug and Play identification of the terminal adapter. (default=1, enabled)

S10 – Lost Carrier To Hang Up Delay

Only valid with analogue modem option S10 sets the length of time, in tenths of a second, that the analogue modem waits before hanging up after a loss of carrier. This allows for a temporary carrier loss without causing the local modem to disconnect. When register S10 is set to 255, the modem functions as if a carrier is always present. The actual interval the modem waits before disconnecting is the value in register S10 minus 0.6s. Therefore, the S10 value must be greater than 0.6s or else the modem disconnects before it recognises the carrier. Range: 1–255 tenths of a second Default: 14 (1.4 seconds)

S16 – Last ocurred CAPI/ISDN error cause

See table 6 on page 96.

S36 – LAPM Failure Control

Only valid with analogue modem option Bits 0–2 This value indicates what should happen upon a LAPM failure. These fallback options are initiated immediately upon connection if S48=128. If an invalid number is entered, the number is accepted into the register, but S36 will act as if the default value has been entered.

0 Modem disconnects. 1 Modem stays on-line and a Direct mode connection is established. 2 Reserved. 3 Modem stays on-line and a Normal mode connection is established. 4 An MNP connection is attempted and if it fails, the modem disconnects 5 An MNP connection is attempted and if it fails, a Direct mode connection is

established. 6 Reserved. 7 An MNP connection is attempted and if it fails, a Normal mode connection is

established. (default)

S40 – General Bit Mapped Options Status

1 0 Fallback/fall forward enabled (%E2) (default) Bits 3–5, 7 Reserved.

S46 – Data Compression Control

Only valid with analogue modem option S46 controls selection of compression. The following actions are executed for the given values:

S46 136 Execute error correction protocol with no compression. 138 Execute error correction protocol with compression. (default)

44 6607-2204

S48 – V.42 Negotiation Control

Only valid with analogue modem option The V.42 negotiation process determines the capabilities of the remote modem. However, when the capabilities of the remote modem are known and negotiation is unnecessary, this process can be bypassed if so desired.

S48 0 Disable negotiation; bypass the detection and negotiation phases; and

proceed with LAPM. 7 Enable negotiation. (default) 128 Disable negotiation; bypass the detection and negotiation phases; and

proceed at once with the fallback action specified in S36. Can be used

to force MNP.

S86 – Call Failure Reason Code

Only valid with analogue modem option When the internal analogue modem issues a NO CARRIER result code, a value is written to S86 Register to help determine the reason for the failed connection. S86 records the first event that contributes to a NO CARRIER message. The S86 register is only updated when the NO CARRIER is sent as result from a broken connection to an analogue subscriber. The code definitions are:

S86

0 Normal hangup, no error occurred. 1 Reserved. 2 Reserved. 3 Call Waiting caused disconnect. 4 Physical carrier loss. 5 No error correction at the other end. 6 No response to feature negotiation. 7 This modem is async only; the other modem is sync only. 8 No framing technique in common.

9 No protocol in common. 10 Bad response to feature negotiation. 11 No sync information from the remote modem. 12 Normal hangup initiated by the remote modem. 13 Retransmission limit reached. 14 Protocol violation occurred. 15 Lost DTR. 16 Received GSTN cleardown. 17 Inactivity timeout. 18 Speed not supported. 19 Long space disconnect. 20 Key abort disconnect. 21 Clears previous disconnect reason. 22 No connection established. 23 Disconnect after three retrains. 24 Call Waiting tone detected.

S91 – PSTN Transmit Attenuation Level

Only valid with analogue modem option In non-PCM modes (V.90 or K56flex are PCM modes), S91 sets the transmit attenuation level from 0 to 15 dBm for the PSTN mode, resulting in a transmit level from 0 to –15 dBm. In some countries, the transmit level may not be changed. Default: 13.

S92 – Fax Transmit Attenuation Level

Only valid with analogue modem option S92 sets the transmit attenuation level from 0 to 15 dBm for the fax mode, resulting in a transmit level from 0 to –15 dBm. The fax mode is used when alarm message type (mtype) is set to Fax. In some countries, the transmit level may not be changed. Default: 13.

S93 – Unknown AT command handling

Controls the response to unknown AT-commands

0 Undefined AT commands will be responded with ERROR (default) 1 Undefined AT commands will be responded with OK

S210 – V.34 Symbol Rates

Call number display:

<rn> = call number of remote site

In AT command mode, call number display (does not belong to the AT command standard) can be turned on by issuing the command ATV2 or ATV3. If turned on, the call number of the caller is shown with the Connect- or Ring-message (in pointed brackets), depending on the signaling in D-channel.

If the ID-90 is used at the public network then the call number of the remote site (including area code) is displayed.

Example: CONNECT 64000 <040890880>

Error cause display:

<xx> = ISDN release (error) cause, hexadecimal Example: NO CARRIER <#34F0>

In AT command mode, error cause display (does not belong to the AT command standard) can be turned on by issuing the command ATV2 or ATV3. The shown error causes use the coding defined by the CAPI definition. ISDN error causes from the ISDN network are always coded as 34xxH, where xx represents the hexadecimal version of the ISDN error cause (see page 92). All other causes are CAPI error causes (see page 98).

X.3 PAD

If you connect an asynchronous DTE to the X.31-service, you can use the integrated PAD of the ID-90. You can use for example the command stat to see the status of the connection. To setup PAD mode please use the configuration command “cmds = 1”.

X.3 command set – integrated PAD

The following PAD-Commands regarding the specifications X.28/X.29 are supported:

Parameter of the integrated PAD

Using the PAD command “set x:n” you can change the parameter according to ITU specification X.3. After changing one or more X.3 parameter you can store the change non volatile by issuing “exec save”. The stored parameter can be reloaded with the command “exec load”. After an X.25 connection is cleared the PAD parameter will be reset to the last active profile (rsp. default).

International Parameters 1 through 12

1 Enable (disable) switch to command mode

Defines whether the terminal user may switch from data to command mode (e.g. to change a X.3 parameter), and – if he may – which key(s) must be pressed to make the switch.

Valid Parameter Values: 0 Switch to command mode disabled. 1 Switch to command mode enabled

switch by pressing the key combination <CTRL>+P (hexdecimal 10, decimal 16)

n Switch to command mode enabled

Regardless of the value set in parameter 3, the data packet will always be forwarded under any of the following conditions:

• when the input buffer holds a full data packet and parameter 15 is set to 0 (zero)

• when the input buffer is full and parameter 15 is set to 1 in this case, one data packet will be sent and the remaining data will be shifted forward in the input buffer

• after the first character of a PAD command is entered

• following the entry of the BREAK signal (command INTD) – also see parameter 7

• after the timeout of the timer set with parameter 4

4 Timer for Data Forwarding

Defines the timeout interval, following which the collected data will be sent as a data packet even if the defined packet size was still not reached. The timer is reset each time a data packet is sent, even if it was sent as the result of the Data Forwarding Character (see parameter 3).

Valid Parameter Values: 0 No timeout, thus no time interval 1 Immediate transfer, thus each character is immediately transferred

as a data packet.

nntime interval in units of 50 msec. (1/20 of a second) and the value

must be an integer in the range from 2 to 255. Example: n = 40 => time out interval of 2.0 seconds

A data transfer timeout is only permitted, when parameter 15 is set to 0 (zero).

ISDN access control

Using these commands you can setup a table, to allow only dedicated callers to get a connection to the ID-90.

If this list is empty (default) or one entry is set to star (*), any incoming call is allowed.

Every incoming call that does not fit to one of the entries of acctab will be ignored. The received calling party number is compared to every entry beginning at the last digit and is stopped when the shorter number is completely compared.

acctabx nn/ss set entry number x to ISDN number nn and subaddress ss acctabx - clear entry number x acctabx * allow all incoming calls to be accepted acctabx show entry number x acctab show all entries

Maximum number of entries = 5; x = 1..5 Maximum length of ISDN number = 20 digits Maximum length of subaddress = 20 digits The ISDN number nn can contain wildcards:

* : represents one or more digits ? : represents exactly one digit

Note: If a subaddress is set, the received calling subaddress must

be identical to the subaddress that is set.

Examples:

acctab1 1234567890 accept only specified number acctab2 *456* accept all numbers with 456 somewhere in the middle acctab3 ?2345678?? accept all number with 2345678 in the middle peceeded by

one digit and followed by two digits.

acctab2 *1234/987 accept all numbers that end with 1234 and have the subad-

dress 987 acctab3 * accept all incoming calls without subaddress acctab3 - clear entry no. 3

Note: If you are not sure, in which format the calling number will be presented with an

incoming call, please use the command ATV2 to see the the format of the calling number in the RING message. This number can be entered into the acctab.

596607-2204

User to User Signalling UUS1

With outgoing and incoming calls the transmission of User-to-User-Data (UUS1-data) can be performed using the ISDN supplementary service UUS1. The UUS1-data are transmitted transparently from the calling party to the called party before the B channel connection is fully established.

Please note, that this ISDN service typically has to be enabled by the ISDN service

provider and may be charged additionally.

See the command ATD in AT command set:

Example: ATDisdnnumber[//<UUS1-data>] (PAD:) X25number[I<ISDNnumber>[//<UUS1data>]]

“//”: separator for UUS1-data

The UUS1-data have a maximum length of 128 Bytes and will be interpreted as ASCII characters. Incoming UUS1-data are presented as enhancement to the RING and CONNECT message.

AT: RING [<rn>][//<UUS1-data>]

CONNECT [<rn>] [//<UUS1-data>]

PAD: <X.25addr>I<isdnnumber>[//<UUS1-data>]

COM

Note: The presentation of UUS1-data has to be enabled by command ATW1.

The data are presented as ASCII characters.

An incoming call can be accepted (S0 register set to 0) by an ATA or rejected by an ATH combined with the transmission of UUS1-data (AT only):

ATA [//<UUS1-data>] ATH [//<UUS1-data>]

Examples:

ATD1234567890//userdata#010203*ende RING //userdata RING //#01020304

60 6607-2204

Sub addressing

With outgoing and incoming calls the transmission of subaddresses can be performed using the ISDN supplementary service SUB. The subaddress is transmitted transparently from the calling party to the called party before the B channel connection is fully established.

Please note, that this ISDN service typically has to be enabled by the ISDN service provider

and may be charged additionally.

The subaddress is separated by an “/” from the called number.

The functionality Subaddressing can be used with the dialling procedures AT-command set, X.3 PAD and automatic call.

Examples:

ATDisdnnumber[/subaddr]

isdnnumber Dialling called party number subaddr Called subaddress

RING [<rn>[/subaddr]] CONNECT [<rn>[/subaddr]]

rn Calling party number subaddr Calling party subaddress

The own subaddress (calling subbaddress) can be setup using the configuration command sub.

Note: The subaddress can be entered additionally into all tables that contain

ISDN numbers for dialling or checking an ISDN address.

“Hotline” call

Automatic call establishment can be activated in three ways:

1. Initiated by an activation of the DTR control line (cmds= 6).

2. Initiated by activity of the Data line from DTE (cmds=7), autobauding is disabled in this mode.

3. Initiated at power on reset, “always on” (cmds=8).

When the cmds-parameter is set to 6,7 or 8 baudrate will automatically be set to 9 600 bit/s (br=4). The status line DCD can be used to indicate a successful connection, (see com- mand cdcd). If a connection cannot be established successfully an automatic retry will be started. The duration of trying to establish the connection and the pause for next retry can be configured. The dialled numbers are taken from the table catab, all numbers from the call table catab will be taken one after each other.The parameter cato sets the timeout for establishing the call, capa the pause between call attempt and catry the number of retries. The call can be disconnected through deactivating DTR see cdtr parameter, or through using the inactivity timer idle. To return to the AT- or Configurator command set the DIP-switches can be used SW3:5-7.

Using Multilink PPP

To enable Multilink PPP handling within the ID-90 please enable the B channel protocol MLPPP: atb31 or prot = 31. ML-PPP may be used with different authentification procedures during the call up of the line. One of these is CHAP. You may enable ML-PPP CHAP by the following steps:

• Type “at**chappwd=<password>” to input your password in the ID-90.

• Type “AT&W” to store the setting in the ID-90.

Afterwards a ML-PPP connection is initially made using CHAP authentification. If the server does not handle CHAP an automatic fallback to PAP is performed. Warning: Since the password is shown in plain text it may be disclosed

by unauthorized persons.

Details on Multilink PPP

The following authentication protocols (AP) are supported by ID-90 when running Multilink PPP (ML-PPP)

• Password Authentication Protocol (PAP)

• Challenge Handshake Authentication Protocol (CHAP) with the variants

• MD5 according to RFC 1321

• Microsoft Chap according to RFC 2433

PAP exchanges the password in clear text format in the B-channel, whereas CHAP encrypts the password according to the algorithms described in the RFCs mentioned above. Due to the fact that the password cannot (at least not with reasonable effort) be derived from the data exchanged on the first link during connection establishment the much safer CHAP protocol can be used only if the password chappwd is locally stored on the TA. The following basic rules apply when the TA is configured to run ML-PPP:

1. If the remote side requests (in the Link Control Protocol LCP ConfigRequest) an AP that the TA can handle, the request is forwarded to local side.

2. If the remote side requests an AP that the TA cannot handle, the TA proposes the safest protocol depending on its capabilities:

• PAP if no password chappwd is locally stored,

• CHAP MD5 if a password chappwd is locally stored. This step may be repeated a limited number of times only, if this number exceeds, the TA falls back to single link operation until the next connection is tried.

3. Once the local side rejects (with a LCP ConfigNak) an AP that was alternatively proposed by the TA (see previous rule), the TA falls back to single link operation until the next connection is tried. Local and remote side may negotiate any AP they like .

4. At the end of the link setup procedure the negotiated AP is checked and, if supported, is used for the second link too. If the final AP is not supported the second link is not established, the TA falls back to single link operation until the next connection is tried.

Note that some hosts are very strict, e.g. if PAP is proposed by the TA due to the lack of a locally stored password chappwd they simply hang up the connection without any chance to negotiate anything else. In these cases the TA should be configured for single link PPP operation, or, alternatively, the chappwd should be supplied and stored on the TA.

616607-2204

Call Bumping

A ML-PPP connection uses both B-channels of the S bus. To accept an incoming call (i.e. for telephony) during a ML-PPP session one B-channel has to be released. This is called Call Bumping. To enable Call Bumping proceed as follows:

• Activate call waiting on the S bus. It has to be activated in the ISDN switch and is a feature of the ISDN line you ordered.

• Open the “properties” of the dial-up link you are using for ML-PPP and “additional settings”. Input “at**cmlp=1” as an additional parameter.

• If there is an incoming call during a ML-PPP session the TA will drop one B-channel and an ISDN telephone attached to the S bus will be ringing to accept the call.

Bandwidth on demand (“BOD”)

Enabling this feature will cause the TA+POC to use the multilink PPP protocol to enhance the ISDN throughput using the second B channel automatically:

• If the throughput of the internet connection is higher than a definable value a second B channel connection will be established automatically and for data transfer used.

• If the throughput of the internet connection is lower than a definable value the second B channel connection will be disconnected automatically.

See commands bod, bodiv, bodit, boddv and boddt. Note: call bumping (cmlp) has higher priority than bandwidth on demand.

X.25 address translation table

With every outgoing X.25 call the ISDN number will be taken out of the corresponding entry table in xtab.

If no entry is found the X.25 address will be used as the ISDN number.

When an ISDN number is setup in the dialling command string with AT commands or X.3 PAD commands, the xtab entries will not be used.

If an ISDN number is setup using the command dad, the table xtab will not be used.

xtabx <xadr>I<nn/ss> set entry number x to ISDNnumber nn/ss

and X.25 address xadr The X.25 address can contain wildcards:

* : represents one or more digits ? : represents exactly one digit

xtabx - clear entry number x xtabx show entry number x xtab Show all entries

Maximum number of entries = 5; x = 1..5 Maximum length of ISDN number = 20 digits Maximum length of subaddress = 20 digits

Note: The table is valid for X.25 in B channel and X.31D rerouting only.

Examples: xtab1 45400029003i04089928392

62 6607-2204

X.25 D channel rerouting

If the protocol X.25 D channel (prot = 21) is selected an automatic establishment of a B channel connection can be selected, if the X.25 call using the X.31-D channel is not successful. The B channel connection will be started if

• no successful X.25 connection is established within of a timeout set by command “cato” in seconds

• an error is reported from X.31 D channel line.

The rerouting will be activated by setting the configuration command “x31rr=1” (from PAD please enter “exec x31rr=1”). The ISDN number used for establishment of the B channel connection will be taken from the table xtab dependent of the entry found in the table. If the X.25 address meets no entry, the rerouting will not be used.

Example:

1. To enable rerouting for all X25 addresses: x31rr 1 xtab1 *i04089928392

2. To enable rerouting for the x25 address 45400012345 and 45400012389: x31rr 1 xtab1 45400012345i04089928392 xtab2 45400012389i04089928392

xtab1 454000123*i04089928392

xtab1 454000123??i04089928392

636607-2204

Alarm Input settings

With configuration commands you can set up the conditions for the four alarm inputs. By entering the command at**alarm the settings made to all four inputs will be presented. There is one entry for each alarm input and parameter except for transno and maxreties witch has only one entry each that is common to all alarm inputs. To execute a ID-90-configuration command out of the AT command mode you have to issue the command at** together with the parameter name e.g. at**mtype2 1. In configuration mode or at remote access you just have to enter the parameter name.

Maximum number of entries = 4; x = 1..4 The following parameters has to be set to accomplish the alarm setting.

opnumberx ISDN number to the operator that provides SMS service messagex Alarm text message mtypex Type of transfer method for the message (SMS, Hotline text). recnox Telephone number to the receiver of the text message. transno Transmitter (calling party) ISDN number (Used as information to the

receiver of a SMS call) maxretries Max number of retries on failed transmission of a message. trigcndx Trig condition for the alarm input Break or Make. opwdx Password, used by TAP-protocol

Example:

To set the alarm input 1 to be triggered on a Making contact condition and transfer a SMS text message to a receiver GSM telephone:

opnumber1 00491722278000 message1 Motor 1 Over temp mtype1 0 (0 = SMS UCP-protocol [default],

1 = Hotline text, 2 = SMS TAP-protocol) recno1 0172555555 transno 01721234567 (Common for all alarm inputs) maxretries 4 (0 default, limits 0..9) trigcnd1 2 (0 = No cond.(default) 1 = Break cond. 2 = Make cond.)

Note: It is of importance that you check the physical connection to the alarm inputs before setting parameter trigcnd to avoid unintentional transmission of alarm messages.

TA+Configurator command set

The settings of the ID-90 for the serial interface and the S0interface are called configuration. The ID-90 is delivered with a set of pre-set values. In the following section it will be shown how, by using the configuration commands, you can examine the configuration of the ID-90 and if necessary change it. The values can be stored in non volatile memory; this means they'll remain unchanged even if the power supply is disconnected.

You can configure the ID-90 in the following ways:

• by using TA+ configuration commands entered by a locally connected PC.

• by using TA+ configuration commands entered via the ISDN access (remote configuration).

• by using the AT command set entered by a locally connected PC.

The configurator can be entered in the following ways:

• remote via ISDN.

• by using a special command from the asynchronous dialup command interface (AT: “ATCONF”).

Configuring the ID-90 with AT commands

To execute one TA+configuration command cmd out of the AT command mode you have to issue the command: “at**cmd” . To call up the TA+configurator please use the command “atconf”. You can leave the TA+configurator by the command “quit”.

Note: After altering one of the profile values you have to

give the additional

commands save

and reset. This is necessary to save and activate these

new parameters.

Configuring the ID-90 with X.3 PAD

To execute one TA+configuration command cmd out of the X.3 – PAD command mode you have to issue the command: “exec cmd” . To call up the TA+configurator please use the command “conf”. You can leave the TA+configurator by the command “quit”.

Note: After altering one of the values you have to give the additional commands

save and go. This is necessary to save and activate these new parameters.

66 6607-2204

Configuration using the TA+Configurator commands (remote)

The ID-90 to be configured is referred here as “remote ID-90”. The ID-90 to configure is referred as “local ID-90”. Please make sure that the remote ID-90 to be configured at the other end is connected to the ISDN line and powered up.

• Connect the local ID-90 to ISDN interface

• Connect the PC's com-port to the DTE interface of the local ID-90.

• Connect the power supply to the mains socket.

• Start a terminal emulation program (i.e. Windows-Terminal)

• Configure the local ID-90 with the B channel protocol X.75 and blocksize 2048 (ATB10).

• Set up an ISDN connection to the remote ID-90 to be configured by using the com-

mand: ATD<ISDN-No>e<↵>. The extension “e” at the end of the calling number gives

a connection to the internal remote access of the remote TA+PP2. The called ID-90 configurator acknowledges by requesting the remote password. Please enter the correct password (default: no password, just return). Now you can work with the configurator by using the TA+Configurator commands.

• Configure the parameter for the remote ID-90 from your terminal program and store them (if wanted).

Example: To change the used B channel protocol to X.75 please enter the following com-

mands:

prot 10<↵> (set protocol to X.75 – blocksize 2048) save<↵> (save the new configuration)

Hint: The active set of parameters can be displayed on screen by the configurator

with the command “show<↵>”. If necessary the remote ID-90 can be reset using the command “reset<↵>”.

• Hang up the ISDN connection by leaving the configurator using the command quit. Leave your terminal program. After the next reset the changes will be active.

Now the configured remote ID-90 with the new set of parameters can be used by running the needed PC program.

676607-2204

Remote access control

Using the following commands you can setup a table, to allow only dedicated callers to get a connection to the remote management facilities inside the TA. If this list is empty (default) or one entry with a star (*) is set, any incoming call is allowed. Every incoming call that does not fit to one of the entries of acctab will be rejected with the ISDN cause “call rejected”.

racctabx nn/ss set entry number x to ISDN number nn and subaddress ss racctabx - clear entry number x racctabx * Allow all incoming calls to be accepted racctabx Show entry number x racctab Show all entries

Maximum number of entries = 3 Maximum length of ISDN number = 20 digits Maximum length of subaddress = 20 digits The ISDN number can contain wildcards:

*: represents one or more digits ?: represents exactly one digits

Example: racctab1 1234567890 ; accept the only specified number

racctab2 *456* ; accept all number with 456 somewhere in the

middle

racctab3 ?2345678?? ; accept all number with 2345678 in the middle

cb – callback security

The callback functionality makes the established link more secure. After an incoming call the adapter will make a callback to either a preconfigured number or to the incoming number. The callback can be protected by a password. The unit can also be configured for a secure access without callback.

If the password is enabled, the calling part will be prompted for the password directly after connection. When the password is entered correctly, the adapter will disconnect the current link and make a callback after a preconfigured number of seconds (configurator command: capa [default 3]).

If the unit is configured as ”secure access”, it will allow data only after the password is correctly entered.

After 3 retries of entering wrong password or after 60 seconds, the link will be disconnected and the callback/secure access aborted.

The number to callback must be entered in the catab number table (catab1, catab2 or catab3). The passwords is stored in: cbpwd1, cbpwd2 or cbpwd3. When making a callback to a number stored in catab, the password in cbpwd1 is connected to the number in catab1 (and cbpwd2 to catab2 and cbpwd3 to catab3)

A callback to an analogue modem can be done with ID90-V90 and by storing an ’#’ before the number in catab. (see also the catab command in this manual)

For an even more secure connection please also refer to the acctab command.

Callback control:

0: callback disabled (default) 1: callback enabled, No password needed, callback number only in

position1 in catab (catab1) 2: callback enabled, No password needed, callback to incoming number 3: access security enabled, Password in one or more positions in

cbpwdx (x= 1,2 or 3) 4: callback enabled, Password in one or more positions in cbpwdx

(x= 1,2 or 3), callback to number in catab, (cbpwd1 corresponds to

catab1…) 5: callback enabled, Password in one or more positions in cbpwdx

(x= 1,2 or 3), callback to incoming number 6: callback enabled, Password in one or more positions in cbpwdx

(x= 1,2 or 3), callback to number that is entered after password

check is OK.

see also the following commands: catab, cbpwd, capa, acctab

736607-2204

cbpwd – callback/secure access password

brn = 0: “Adaptive”: same mechanism as brn # 0; the V.110 baudrate will be

created by br rsp. the recognized local baudrate.

Incoming call:

brn # 0: No LLC received: accept incoming call, use in B channel brn for V.110

baudrate. LLC received compliant to brn: accept incoming call LLC received not equal to brn: Reject incoming call: DISCONNECT (cause = incompatible destination).

brn = 0: “adaptive”: No LLC received: accept incoming call, use in B channel

br rsp. the recognized local baudrate for V.110 baudrate. LLC received: accept incoming call, use in B channel the baudrate derived from the LLC as V.110 baudrate.

Frequently used settings for PLC-systems and industrial applications.

Most PLC-systems and other industrial applications require the same changes to the standard settings.

The most commonly encountered problems concern speed, parity and control signals from the connected equipment.

Speed and parity are changed with the switches under the cover. If this action does not solve the problem the modem’s answering codes and possible echoing of commands might be the source of the difficulty. Here below follows a list of commands that might resolve the problems. (The commands may of course be placed on one single command line if desired, as per the example1):

ATV Gives the answering codes in short format. (digits) ATQ1 No result codes are sent on the RS-232/V.24 connection. ATE Commands that are sent from the terminal/computer etc.

are not echoed back to the RS-232/V.24 connection.

AT&C1 DCD will follow the ISDN line status DCD on when ID-90

has detected and synchronised to the ISDN line. AT&K No handshaking. AT**dabort=0 Dialing, answering is not aborted by characters from DTE.

For further information regarding these commands please refer to the specific section of this manual.

Dial up with hardware signalling.

Dial-up can be made by sending an arbitrary character to ID-90 and the DTR-pin can be used to disconnect. A typical application using this method is shown in the example below. The PLC periodically polls a supervisory system, the poll causes the ID-90 to establish a connection to the supervisory system. The PLC also controls the connection breakdown through the contact connecting DSR and DTR. The contact shall normally be closed and only opened shortly to break down the connection. The number(s) to be called is controlled by the variables catab1 – catab3 The modem does not have a redialling function. If necessary this must be handled by other equipment connected. The RS-232/V.24 control signal DCD can be used to indicate the success of connection. Before the command mode is set to Tx hotline the numbers to be dialled has to be defined by the below command.

AT**catabX=nn Where X is 1,2 or 3 and nn the number to dial.

The ID-90 will first try to dial the number stored for catab1 and continue to establish connection to the number stored for catab2 if connection to catab1 is unsuccessful. Only catab1 has to be defined if only one number is to be called.

AT**save Save the number(s).

Now power down the ID 90 and set the DIP-switches according to below figure. After switches has been set power up the ID 90 again (the switches is only reed by ID-90 at power on)

Diagnostic and error messages

For the diagnostic of erroneous situations the following functionality is supported. Please check first the behaviour of LED displays, if an ISDN connection can not be established. Refer to list of LED displays.

Error messages from AT command set

When the extended result messages are selected using the command ATV2 ISDN error codes are displayed in addition to the standard AT result messages. ISDN error causes from the ISDN network are always coded as 34xxH, whereas the last two digits xx represent the ISDN cause in hexadecimal coding. The meaning can be taken from the following tables ISDN causes (see chapter: LED indicators).

Diagnostic using the internal Trace

For more sophisticated debugging an internal trace functionality is implemented. This logging mechanism allows to write activities of the ISDN and the serial interface into a wrap around buffer. The type of entries can be selected by a trace mask.

trcmsk – set tracemask

trcmsk par Setup the mask to select the type of data to be written into the tracebuffer.

Default: D channel Layer 1 and 3, DTE interfacelines, DTE-Data in connection-setup and clearing-phase. The parameter par has to be setup in the following way, all bytes have to be entered (default 00 00 00 07 00 02 05 00): par := bl1 bl2 bl3 dl1 dl2 dl3 sl1 app bl1 reserved bl2 reserved bl3 reserved dl1 D channal layer 1 status default 07

bit0: status bit1: C/I codes after change

dl2 D channel LAPD frames: default 00

bit1: HDLC frames

dl3 D channel layer 3 messages: default: 02

bit1: Messages

sl1 Serial line 1; i.e. first V.24 port; default: 05

bit0: control lines after change bit2: data bytes while connection control (call phase)

app reserved (00)

trcdln – length of trace entry

trcdln xx set trace buffer entries to a maximum length of xx. (default: 256)

trcon – start trace write

trcon set trace to active regarding to tracemask

trcoff – stop trace write

trcoff set trace to OFF independent of tracemask

trcclr – clear trace buffer

trcclr clear actual tracebuffer contents
