time your existing telephone equipment can be used to make calls to other equipment on the Public Switched Telephone

Network (PSTN).

allowing direct connection to the ISDN without the need for an NT1 device. NOTE: Do not attach the WEBGLIDER to an NT1

device.

Introduction

Page 8

Basic Rate ISDN provides two 64 kbps B-channels, each of which can carry a data or a ‘voice’ call. This allows the WEBGLIDER to handle two simultaneous ‘voice’ calls (telephone, fax or modem), or a ‘voice’ call and an ISDN data call, or a data call that uses both B-channels (128 kbps).

Industry standard V.120 rate adaption and V.42bis data compression ensure interoperability with ISDN equipment from other vendors. The WEBGLIDER is able to store up to 32 different numbers and has directories of stored numbers for positive (“whitelisting”) and negative (“blacklisting”) checking of caller ID, allowing secure applications to be developed.

The industry standard AT command set is also included.

WebGlider Connections & Features 2

This section is a quick tour of the WEBGLIDER.

2.1 WEBGLIDER Interfaces

The WEBGLIDER is a Basic Rate Integrated Services Digital Network (ISDN) terminal adapter that allows connection of a PC (or other data terminal equipment) and up to two telephone devices (such as telephones, modems or faxes) to ISDN. The interface connectors are located on the back panel of the unit.

QUICK TOUR

WEBGLIDER

ISDN URS-232 AUX 1 AUX 2 PWR

WEBGLIDER Back Panel

ISDN Connection

The WEBGLIDER connects directly to the ISDN network at the Uinterface. An ISDN network terminator device (NT1) is not required. This port is labelled ‘ISDN-U’ and we have supplied an RJ-45 cable for connecting to the ISDN network. NOTE: Do not

attach the WEBGLIDER to an NT1 device.

Serial Connection

The WEBGLIDER has a serial port for connecting to your PC or other Data Terminal Equipment (DTE). This port is labelled ‘RS232’ and is located on the back panel. The port appears as a DCE (modem-like) connection and can be directly connected to terminal equipment using standard cables.

Connection & Features

Page 14

Telephone Connections

Two “voice” or POTS (Plain Old Telephone Service) ports are provided for connecting telephone equipment such as telephones, answering machines, faxes, or modems to the WEBGLIDER. These ports are labelled ‘AUX 1’ and ‘AUX 2’. Each port supports multiple telephone-type devices up to a Ringer Equivalence Number (REN) of three. WEBGLIDER allows both lines to be used at the same time for two simultaneous telephone calls, if no data call is present. If a data call is present, you can only use one AUX line.

Power Connection

Power for the WEBGLIDER is provided by an external power supply. The power supply is attached to the connector (marked ‘PWR’) on the back panel. The WEBGLIDER does not draw power from the ISDN network. So, if there is no power to the WEBGLIDER, then the telephone ports will not work.

Typical Configuration

The illustration on the next page shows a typical WEBGLIDER configuration with a PC, a telephone, and a fax machine connected to an ISDN line. For a typical configuration (if you have an analog modem), you should assign one AUX port exclusively for that modem. This will allow you to establish either an analog modem call, or a voice call, using a handset plugged into the modem. You can then tele-conference while working on the same document, engage in two-player remote game playing, or do an analog data download. If you do not have an analog modem, just assign one AUX port exclusively to a handset.

yourself with the following terms:

ANALOG PHONE DEVICE: Regular phone handset, fax machine, etc.

AUX1/AUX2: POTS ports on the back of your WEBGLIDER. BRI.: Basic Rate Interface DN: Directory Numbers given to you by your phone company

when you get ISDN service NETWORK (ISDN): Type of switching equipment the phone company uses to connect your ISDN line to their CO (central office) POTS port: (Plain Old Telephone Service), i.e., RJ-11 phone-type jack into which you can plug standard devices like fax machines or telephone handsets.

SPID: Service Profile ID (supplied by your phone company) TA: Terminal Adapter (usually ISDN modem)

Now, continue with the next page to prepare the WEBGLIDER for command line configuration.

Command Line Configuration

Page 20

NOTE: When the WEBGLIDER is configured correctly, the DS indicator will blink at first and then remain on solid. If it is not configured correctly, the DS indicator will blink continuously.

1. Power on the WEBGLIDER and wait for the self-test sequence to be performed. Start your modem software and go to the command screen where you can issue modem “AT” commands.

2. Configure your software for the COM port to which the WEBGLIDER is attached. Set the COM port speed to the desired value. Set the flow control to ‘hardware’ (usually RTS/ CTS). Keep compression (V.42bis) disabled for now. If your dialup service supports compression, re-enable it at a later time.

3. Type AT and press ENTER (or carriage return for non PCs). The OK response should be seen. If you do not see the A character after pressing A, press it a few more times until the WEBGLIDER detects the baud rate and displays an A character.

4. Type ‘AT’ and press ENTER. When you have received the OK response, enter the following command: AT&Q4 and press ENTER.

The following prompt will appear: ISDN-TA>

The WEBGLIDER is now ready to be configured for use. In the example that follows, the information below is used:

WEBGLIDER-460

Page 21

Network NI1 DN1 555-1111 SPID1 6175551 1110100 DN2 555-2222 SPID2 61755522220100 RS232# 5551111 AUX1# 5552222 AUX2# 5551111

5. The first item to configure is the network type. This will be

either National ISDN-1, National ISDN-2, AT&T 5ESS custom

or Northern Telecom DMS-100 custom. Depending on your switch type, enter the command as follows:

For National ISDN-1 (default)

SET NETWORK NI1

or for National ISDN-2

SET NETWORK NI2

or for AT&T 5E5 custom

SET NETWORK AT5

or for AT&T 5E6, 5E7, 5E8, 5E9 custom

SET NETWORK AT9

or for Northern Telecom DMS-100 custom

SET NETWORK DMS

Note: Some AT&T 5ESS and DMS-100 switches run custom; others run National ISDN (NI1 or NI2) protocols. Check this with your ISDN provider.

Command Line Configuration

Page 22

6. Your ISDN provider will have provided you with Directory Numbers (DNs). These are your ISDN numbers. Each DN is provided with a Service Profile ID (SPID). The SPID is normally based on the DN and includes the area code and a suffix. You need to configure the WEBGLIDER with your DNs and SPIDs.

To do this, use the command:

SET DN 1 <dn 1> <spid 1>

Where dn 1 is one of your directory numbers (usually your main number) and spid 1 is the associated SPID.

Note: The DN does not include the area code. Repeat this command for your other directory numbers, using SET DN 2 for the second number etc.

Example: (area code 617, SPID suffix 0100) SET DN 1 5551111 61755511110100 SET DN 2 5552222 61755522220100

This example sets the first Directory Number to 5551111 with SPID 61755511110100 and the second Directory Number to 5552222 with SPID 61755522220100.

7. Now that we have set the DNs and SPIDs, we can assign ISDN numbers to the WEBGLIDER ports. Assigning numbers to ports allows incoming calls to be sent to the right ports.

To set the ISDN number for the RS-232 (data) port use the command: SET RS232 DN <dn>

WEBGLIDER-460

Page 23

To set the number for the AUX 1 port use the command:

SET AUX1 DN <dn>

and to set the number for AUX 2 use the command:

SET AUX2 DN <dn>

Where dn is the directory number you wish to use for this port.

Note:

The directory number used for an AUX port must have been

assigned previously using the SET DN command.

Example:

SET RS232 DN 5551111 SET AUX1 DN 5551111 SET AUX2 DN 5552222

This example sets the DN for the RS-232 port to 5551111, the DN for AUX 1 to 5551111, and the DN for AUX 2 to 5552222.

Note: The RS-232 and AUX 1 ports have the same number. Incoming calls will be routed to the correct port on call type (voice calls to AUX 1 and data calls to RS-232). ISDN digital data will be answered by the TA only (special signalling) and analog calls for an analog modem, fax machine, or phone will pass through to one of the AUX ports. Do not assign the handset to the same AUX port assigned to the RS232. This is so that when the RS232 port is busy with an ISDN signal, connection through the phone is still available.

Command Line Configuration

Page 24

8. Before saving, you should make sure all settings are as you intended. At the ISDN-TA prompt, type the following and press ENTER:

SHOW NETWORK

(shows the network (switch type) the WEBGLIDER is configured for)

SHOW DN

(shows all DNs and SPIDs)

SHOW RS232 DN

(shows the DN assigned to the RS232 data port)

SHOW AUX1 DN

(shows the DN assigned to the AUX1 port)

SHOW AUX2 DN

(shows the DN assigned to the AUX2 port)

9. To save the configuration, enter the command:

SAVE

This operation will take a few seconds to complete.

To leave configuration mode without saving, type EXIT. You can now use AT commands.

WEBGLIDER-460

Page 25

Summarizing the Commands from the Previous Example

Note: If your switch is running one of the 5E custom protocols, it may be configured as point-to-point or multipoint (default). Enter the following command only if you have an AT&T custom point-to-point configuration:

ISDN-TA>SET TOPOLOGY POINT-TO-POINT

Example:

ISDN-TA>SET NETWORK NI1

(This sets the WEBGLIDER for National ISDN-1 switch type.)

ISDN-TA>SET DN 1 5551111 61755511110100

(where the DN1 is 5551111 and the SPID1 is 61755511110100)

ISDN-TA>SET DN 2 5552222 61755522220100

(where the DN2 is 5552222 and the SPID2 is 6175552220100)

ISDN-TA>SET RS232 DN 5551111

(where the phone number to the RS232 port to send/receive data is set to 5551111)

ISDN-TA>SET AUX1 DN 5551111

(where the AUX1 POTS port is set to use 5551111)

ISDN-TA>SET AUX2 DN 5552222

(where the AUX2 POTS port is set to use 5552222)

ISDN-TA>SAVE

NOTE: When the WEBGLIDER is configured correctly, the DS indicator will blink at first and then remain on solid. If it is not configured correctly, the DS indicator will blink continuously.

Command Line Configuration

Page 26

You have now set up your WEBGLIDER for basic operation, you should now be able to make and receive calls from all three ports.

To make a call on the data port, use AT dialing through your communications software. To make a call on AUX1 or AUX2, pick up the handset, wait for a dial tone, and make a call in the normal way. Or, use AT dialing through the communications software you have configured for your analog modem attached to one of the AUX ports.

Configuration is not limited to the items discussed above. See Appendix I for a full explanation of each command line option.

WEBGLIDER-460

Page 27

Troubleshooting A

Should your WEBGLIDER not function as expected, check the following before seeking support:

WEBGLIDER will not respond to DTE

1. Check the LEDs to make sure that the power on self-test has

completed successfully. When the test completes successfully, the LEDs will flash in a sweep sequence. If a test fails, one or all of the LEDs will be flashing.

2. Make sure that the cables used conform to the specifications

defined in Appendix B of this manual and that both ends of the cables are securely connected.

3. The WEBGLIDER will autobaud to the speed of your DTE. If

autobaud appears not to work after pressing the A key several times, try changing the speed of your DTE. If you are using a PC, make sure your communication software is also configured to use the correct COM port.

TROUBLESHOOTING

4. Some asynchronous devices have specific requirements for DCD

and DSR operation. The default behavior of these signals for the WEBGLIDER is that DCD and DSR are always on for AT dialing. Check that this method of operation is acceptable to your PC or terminal. DCD and DSR behavior can be modified using the AT&C and AT&S commands.

Troubleshooting

Page 28

5. If you are using AT dialing and the WEBGLIDER was previously responding, it could be that the AT interface has been reconfigured not to respond. To check this, enter ATE1Q0 to enable ‘echo’ and disable ‘quiet mode’.

Get AT response but cannot make a call on data port, or no dial tone on AUX port

1. If the DS light is off, check the connection to the ISDN line and make sure that the WEBGLIDER is not connected to an NT1. Also check that the network type is configured correctly.

2. If the DS light is flashing, there may be a problem with your SPIDs or the network type configuration. Check your SPIDs with your ISDN service provider (telco) and try adding trailing zeroes to the SPID. If you change the SPIDs don’t forget to SAVE the configuration. Ask your service provider to run a test on your line from the central office.

3. Try setting the CALL SETUP option to both MINIMUM and MAXIMUM.

WEBGLIDER-460

Page 29

WEBGLIDER displays double characters

Local-echo is enabled in the terminal. Reconfigure the terminal to disable the local echo.

WEBGLIDER connects but the connection is then lost

1. If you are using rate adaption, check that the device you are connecting to is configured for the same rate adaption standard as the WEBGLIDER. The WEBGLIDER uses V.120, which will not interoperate with V.110.

2. Check that the PPP is not enabled if calling a line without PPP. Disable PPP by typing AT&Q0. Enable it by typing AT&Q3.

WEBGLIDER will not auto-answer on RS-232 port

In AT dialing mode ‘automatic-answer’ is enabled by setting the value of the S0 register to 1 (ATS0=1).

WEBGLIDER very slow or re-booting

Serial cables greater than a few feet in length connected to the WEBGLIDER and left unterminated may cause problems. These cables should be plugged into a DTE or disconnected from the WEBGLIDER.

Command/Protocol Overview C

In most cases, your communications software will set and control the operation of your WEBGLIDER. Following is a brief survey of the most commonly used Hayes-compatible AT commands for use with your WEBGLIDER. In addition, we’ve also provided information on extended AT command sets, SRegisters, and commands and registers for high-level protocols such as MNP, V.42/V.42bis, and V.32/V.32bis.

NOTE: This section makes references to Hayes-compatible commands, originally developed for analog modem

OVERVIEW

COMMAND/PROTOCOL

communications. Bear in mind the WEBGLIDER is not an analog modem. It is a digital device allowing communication between two DTE devices, and is also referred to as terminal adapter (TA). The WEBGLIDER supports the AT command set to ensure compatibility with today’s communication programs.

It will rarely be necessary to use ‘AT’ commands and SRegisters in command or terminal mode. We include them here for more advanced users who may prefer command mode operation, or r equire special settings. See pages 51-74 for additional details.

Hayes-compatible commands consist of a basic command set and an extended command set. The basic set involves functions such as dialing a number, or putting the modem on-hook (i.e., replacing the telephone handset).

Extended commands allow more sophisticated control of the device such as adjusting transmission speed, or initiating highlevel functions like data compression or error correction. These functions are defined and controlled by the available protocols mentioned above. A protocol is a set of standards by which

Command/Protocol Reference

Page 34

data communications operate. Every AT command includes an “AT” prefix, followed immediately by the command and, in many cases, additional parameters. Multiple commands can be entered at the same time from your communications software.

AT Command[parameter] [parameter] ... PRESS ENTER

Example: ATH or ATH0 tells the modem to disconnect

Extended commands were developed to provide greater functionality and control over modem operations. Their format is the same as the basic command except that an additional parameter is required following the AT prefix and before the numerical parameter. Examples: AT&V displays the value of the S-Registers, configuration parameters, and ISDN address directory (the stored numbers).

S-Registers

Modem command “language” also employs a set of indicators or registers, which are various numerical values all with a standard “S” prefix, hence S-Registers. To a large extent, the values defined in the S-Registers regulate the operation of the WEBGLIDER and the function of some commands in the AT command set.

Example: S-Register 7, or S7=n, defines the length of time the WEBGLIDER will wait for an outgoing call to be established before reporting NO CARRIER to the DTE. In this case, the acceptable range is 0-255 with a default value of 20. With S7=20, the WEBGLIDER will wait 20 seconds for an outgoing call to be established before reporting NO CARRIER.

Data Communication Protocols

These protocols represent various domestic and international standards which enhance modem performance and reliability. The protocols are activated and controlled by a variety of extended AT commands and S-Registers.

MNP stands for Microcom Networking Protocol and is a protocol developed by Microcom for full-duplex, error-free communications. This protocol detects and corrects errors which can result from telephone line noise and other signal distortions. There are several classes of MNP operation also referred to as service classes. Class 5 maximizes data transfer rate and provides compression which can significantly increase data throughput.

The “V-Dot” standards are more numerous, but have a single origin: the International Telecommunications Union Telecommunications Standards Sector (formerly the Consulting Committee for International and Telephone and Telegraph or CCITT). Some of the lower-level standards such as V.21 and V.22 have “domestic” equivalents as developed by the former Bell System, also referred to as Bell standards. The “V.Dot” standards may be summarized as shown on the following page.

Command/Protocol Reference

AT Command Reference H

Overview

Your WEBGLIDER provides serial, asynchronous dialing for the data port (RS-232) using standard AT commands with extensions for getting the most out of ISDN.

The ISDN command set was originally developed for use with Vseries modems that operate over the telephone network. While keeping the standard AT commands that are used for making and answering calls we have made enhancements to allow access to ISDN supplementary services including caller ID and user-to-user signalling over the D-channel at call setup and clear down time. Note: Not all ISDN networks provide caller ID and user-to-user signalling.

Introduction to Commands

AT commands are entered on a command line which starts with the characters AT or at and ends when a Carriage Return (see S3 register) character is received. The maximum length of a command line is 256 characters. Multiple commands can be concatenated together, in which case the AT prefix need only appear before the first command.

Example: ATS112=3VD14085552609

This single command has the same effect as the three commands:

REFERENCE

AT COMMAND

ATS112=3 ATV ATD14085552609

AT Command Reference

Page 52

The command line may be edited using the Backspace (see S5 register) character. To repeat the last command A/ or a/ should be entered (without Carriage Return). All commands are in ASCII.

Introduction to Responses

The WEBGLIDER sends response codes to the PC (or DTE) when commands are issued or events such as call establishment happen. These response codes can be in English text (default) or numeric code form. Numeric mode is useful when the device is being software controlled. The commands Q and V can be used to set the response mode. In text mode the WEBGLIDER will respond to badly formed commands with ERROR. In most cases (but not when dialing or answering) correctly formatted commands receive an OK response when they have been processed. All responses are in ASCII.

States

A port configured for AT dialing can be in one of two states, command state or data state. When in command state the WEBGLIDER interprets local DTE data as commands. The data state is entered when a call is set up. In this state data from the local DTE is sent over the connection to the remote DTE. The DTE can get from data mode back to command mode using the escape command (+++) and go back on-line again when required using the online command (ATO).

WEBGLIDER-460

Page 53

Commands

This section describes the AT commands in detail, giving examples where relevant. The commands are grouped as follows:

• Mode selection

• Call control commands

• Extended call control commands

• DTE interface commands

• Miscellaneous commands

• Configuration

For notation conventions please refer to Section One.

Mode Selection &Q Communication Mode

Syntax: AT&Q[0|1|2|3|4] Description: Sets the communication mode as follows: &Q0 AT dialing, asynchronous operation (default)

&Q1 DTR dialing, asynchronous operation &Q2 Dial-on-data, asynchronous operation &Q3 PPP mode (asynchronous to synchronous PPP

conversion; used for most Internet ISDN services)

&Q4 Command line configuration mode.

DTR dialing and dial-on-data are described in Section Four. PPP mode provides AT dialing, but when the connection is established asynchronous to synchronous PPP conversion is enabled. Use this option if your internet provider requires synchronous PPP. Command line configuration is defined in Section Four.

AT Command Reference

Page 54

Call Control Commands A Answer

Syntax: ATA Description: This command causes an incoming call to be

answered. The command can be aborted by the PC (or DTE) sending any character when the command is executing.

See also: O, S2

WEBGLIDER-460

&O Display configuration

Syntax: AT&O Description: Same effect as &V

&V Display configuration

Syntax: AT&V Description: This command causes the values of the S-registers,

configuration parameters and ISDN address directory (the stored numbers) to be displayed.

&W Save registers and options as user defaults

Syntax: AT&W Description: The current settings for S-registers and all other

parameters (e.g., directory entries, DTR response, indication format, security, call log etc.) are saved to non-volatile memory as user defaults.

&Z Set directory entry

Syntax: AT&Z<dir id>=<dial string> Description: This command stores the ISDN address dial string in

one of the 32 locations of the stored number directory. The location is specified by <dir id>. Example: AT&Z2=5556874 Sets stored number directory entry 2 to 5556874

Z Reset

Syntax: ATZ Description: This command resets the WEBGLIDER and restores

registers from user defaults.

AT Command Reference

Clear Flash memory (Control R)

To perform this procedure, do the following:

1. Turn the WEBGLIDER off.

2. Hold down the CTRL and R keys at the same time.

3. While holding the keys down, turn the WEBGLIDER back on.

4. Continue holding the keys until the indicators on the WEBGLIDER stop flashing.

5. When the DC and TD indicator lights stay on solid, release the CTRL and R keys. The WEBGLIDER will reboot again. Reset is complete.

CAUTION: Use the CTRL/R function only when you wish to clear the entire contents of flash memory and restore factory default settings. NOTE: You will have to reconfigure the WEBGLIDER after performing this procedure. Refer to the Quick Tour Installation Guide (“Running the Configuration Utility”). Also, the WEBGLIDER loses date and time following a reset.

The SET command parameters are defined below, they are arranged in alphabetical order, rather than type.

SET AUTODIAL Type: Data port parameter Syntax: SET AUTODIAL <stored number index> <attempts>

Description: This command is only relevant when the dialing mode is set to DTR dialing or dial-on-data. Dial-on-data mode only supports an inactivity timer where an ISDN connection can be dropped if no data is passed in either direction for a particular period. Parameters for this command are as follows:

stored number index: the index (1-32) into the stored number directory of the number to be called. attempts: the number of connection attempts (0-32) that the WEBGLIDER should make if the connection fails (0 means try forever). redial timer: the time interval in seconds between attempts (0-

3600).

The inactivity timer is the length of time in which no traffic has passed. The device will drop the call. This is only relevant to dialon-data mode and can be disabled if not required, values are in seconds ranging from zero (disabled) to 3600 (60 minutes).

Examples: SET AUTODIAL 4 2 60 0

This example causes stored number 4 to be dialed when the dialing criterion is met (see SET DIALING). If the connection fails, one further attempt will be made after a wait period of 60 seconds. See also: SET DIALING, SET STORED NUMBER

Additional Command Line Options

Page 78

SET AUX1 DN Type: Voice port parameter Syntax: SET AUX1 DN <directory number> Description: This command allows the ISDN number for the

voice port ‘AUX 1’ to be configured. This is the number that will be dialed from the ISDN/PSTN network to ring the AUX1 port.

NOTE: ‘Directory number ’ should not include the area code and should be one of the DNs that have already been configured using the SET DN command. Example: SET AUX1 DN 555 1111

The directory number of AUX 1 is set to 5551111. See also: SET DN, SET RS232 DN, SET AUX2 DN

SET AUX2 DN Type: Voice port parameter Syntax: SET AUX2 DN <directory number> Description: Has the same effect as SET AUX1 DN, but for

port AUX 2 See also: SET DN, SET RS232 DN, SET AUX1 DN

SET AUX2 REDIRECT Type: Voice port parameter Syntax: SET AUX2 REDIRECT <ON | OFF> Description: This causes all incoming calls for AUX 2 to be

redirected to AUX 1. This allows you to have two directory numbers, both directed to a single device. The default setting is OFF.

Example: SET AUX2 REDIRECT ON

Incoming POTS calls to AUX 2 will ring the device on AUX 1 See also: SET DN, SET AUX1 DN, SET AUX2 DN

WEBGLIDER-460

Page 79

SET BLACKLIST n Type: General parameter Syntax: SET BLACKLIST <index> <isdn address> Description: The WEBGLIDER has a configurable ‘blacklist’ that

is intended for ISDN addresses of unwanted callers. The blacklist is used with Caller ID and applies to all three ports (see SET SECURITY). This command allows ISDN addresses to be written into the blacklist directory. Index is the position in the directory (1-32) and isdn address is the number to store (up to 15 digits).

Example: SET BLACKLIST 1 5551234

This stores the number 5551234 in the blacklist entry 1. See also: SET SECURITY, SET WHITELIST, SHOW BLACKLIST

SET CALL SETUP Type: Data port parameter Syntax: SET CALL SETUP <specification> Description: This command solves interoperability problems

between WEBGLIDER and some other vendors equipment. When specification is set to MAXIMUM (default) the ISDN data call made for the RS-232 port accurately specifies V.120 to the network and remote ISDN equipment. It has been found that currently some networks do not support V.120 calls in this form, to overcome this specification can be set to MINIMUM.

SET CALL TYPE Type: Data port parameter Syntax: SET CALL TYPE <VOICE|DATA> Description: ISDN differentiates between voice and data calls,

some ISDN providers tariff these two service differently. The RS232 port makes data type calls, while the two AUX ports make analog/voice calls.

Additional Command Line Options

Page 80

When an incoming call is received the WEBGLIDER uses the call type information as well as the number to route the call to the correct port (e.g. a voice call is not sent to the data port). Under some circumstances it is desirable to override this system, in this case the WEBGLIDER can be configured to make and accept calls of either type on the data port if required. This command is used to set the type of call made and accepted by the RS-232 port.

Warning: If all ports are configured to accept voice calls the response to incoming calls may be unpredictable. Each port you wish to use should be given a different ISDN number.

Example: SET CALL TYPE VOICE

This example sets the call type for the RS-232 port to voice. See also: SET CALL SETUP

SET CHARACTER Type: Data port parameter Syntax:

SET CHARACTER <data bits> <parity> <stop bits>

Description: This command sets the format of asynchronous characters. Data bits is the number of bits in the asynchronous character, this can be 7 or 8. Parity is the method of error checking and can be EVEN, ODD or NONE. Stop bits is the number of stop bits added to the end of an asynchronous character, this can be 1 or 2. The settings configured in this command must match those configured in the locally connected PC (or DTE). The default settings are 8 data bits, no parity and 1 stop bit, (8, N, 1).

Example: SET CHARACTER 7 EVEN 1

Sets the asynchronous character format to 7 data bits, even parity, 1 stop bit. See also: SET SPEED

WEBGLIDER-460

Page 81

SET DATE Type: General parameter Syntax: SET DATE <mm>/<dd>/<yy> Description: This command sets the date within the

WEBGLIDER. If accurate call logging is required the date should be set after power up, otherwise the date will start at 1/1/94.

Example: SET DATE 2/29/96

Sets the date to February 29 1996 See also: SET TIME

SET DIALING Type: Data port configuration Syntax: SET DIALING <dialing mode> Description: This command sets the dialing mode for a port.

Dialing mode can be either: AT for AT dialing (default) DTR for DTR dialing DATA for dial-on-data For DTR dialing one of the stored numbers is dialed when the local DTE becomes ready. Dial-on-data dials a stored number when the local asynchronous DTE sends data (any character) and can timeout after a period of inactivity. These parameters are configured using the SET AUTODIAL command.

Example: SET DIALING DTR

Sets the RS-232 port to DTR dialing. See also: SET AUTODIAL

Additional Command Line Options

Page 82

SET DN Type: General configuration Syntax:

SET DN <index> <directory number> <service profile ID>

Description: The WEBGLIDER can support from one to three Directory Numbers (DNs), how many DNs you have depends on your service provider and what you ordered. Each Directory Number that the WEBGLIDER uses has a Service Profile ID (SPID) associated with it. This SPID is assigned by your ISDN service provider (telco) and needs to be programmed into your ISDN device. You need to use this command before you set up the DNs used by the individual ports. Index is the number you want to configure (start with index 1, the numbers can be entered in any order). Directory number is the ISDN number assigned by your ISDN provider, without the area code. The service profile ID is the identifier assigned by your ISDN provider, numbers and SPIDs are assigned in pairs, be sure to match the pairs.

Example: SET DN 1 5551111 61755511110100

SET DN 2 5552222 61755522220100

Here we are configuring two numbers and corresponding SPIDs. See also: SET RS232 DN, SET AUX1 DN, SET AUX2 DN, SET PROFILE

SET LOG Type: General configuration Syntax: SET LOG <log mode> Description: This command enables and disables logging of calls

to an internal log and allows the log to be cleared (reset). Log mode can be set to ON (start logging), OFF (stop logging), and CLEAR (clear and reset log). See also: SHOW LOG

WEBGLIDER-460

Page 83

SET NETWORK Type: General configuration Syntax: SET NETWORK <network type> Description: This command sets the type of ISDN switch (central

office) that the WEBGLIDER is connected to. This command is usually executed once during initial installation to set the network type. The new network type will only be activated if a SAVE is executed. Network type can be one of the following

NI1 National ISDN-1 NI2 National ISDN-2 AT 5 AT&T 5ESS, version 5 custom AT 9 AT&T 5ESS, version 6-9 custom DM S Northern Telecom DMS-100 custom

Example: SET NETWORK AT5

The WEBGLIDER is configured to operate with an AT&T 5ESS (version 5) central office switch. See also: SET TOPOLOGY

SET PROFILE Type: Data port configuration Syntax: SET PROFILE <profile number> Description: This command sets the B-channel profile, this

controls rate aggregation and data compression for the data port (‘RS-232’) of the WEBGLIDER. Profile number can be 1, 2, 3 or 4 and controls the characteristics as follows:

Profile Compression Aggregation 1 (default) OFF OFF

2 ON OFF 3 OFF ON 4ON ON

Additional Command Line Options

Page 84

Each profile can be given a unique ISDN address (ISDN number and subaddress combination), if more than one profile is given an ISDN address, the WEBGLIDER will automatically switch to the relevant profile when an incoming call is received (depending on the called number). This allows a single device to support incoming calls of all types.

SET RS232 DN Type: Data port parameter Syntax: SET RS232 DN <directory number> Description: This command sets the ISDN number for the ‘RS-

232’ data port. This is the number that will be dialed from the ISDN network to access this port. Directory number should not include the area code and should be one of the DNs that was configured using the SET DN command.

Warning: The SET RS232 DN and SET SUBADDRESS commands apply only to the last profile selected. Select a profile before assigning ISDN addresses.

Example: SET RS232 DN 5552222

Sets the directory number of the RS-232 port to 5552222. See also: SET DN, SET AUX1 DN, SET AUX2 DN

SET SECURITY Type: General configuration Syntax: SET SECURITY <security mode> Description: This command sets the security mode used for

protection against unwanted incoming calls using caller ID. WEBGLIDER security can be off, (no incoming call security), use a blacklist (do not allow calls from list of unwanted callers) or use a whitelist (only allow access to a configured group of callers).

WEBGLIDER-460

Page 85

Security mode can be set to OFF, BLACKLIST or WHITELIST. Up to 32 numbers can be stored in the blacklist and whitelist directories. See also: SET BLACKLIST, SET WHITELIST.

SET SPEED Type: Data port configuration

Syntax: SET SPEED <baud rate>

Description: The WEBGLIDER is designed to do automatic baud rate detection (autobaud). If you experience problems with autobaud at certain speeds the port speed can be set using this command. Speed is the data rate in bits per second and can be: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400 or 460800.

Note: After you have set the speed, autobaud detection is disabled until the unit is restarted.

SET STORED NUMBER Type: General configuration Syntax: SET STORED NUMBER <index> <isdn address> Description: This command allows ISDN addresses to be

written into the stored number directory. Index is the position in the directory (1-32) and isdn address is the number to store (up to 15 decimal digits).

Example: SET STORED NUMBER 30 12127779000

The ISDN number 12127779000 is stored in the ISDN directory, entry 30 See also: SET AUTODIAL

Additional Command Line Options

Page 86

SET SUBADDRESS Type: Data port parameter Syntax: SET SUBADDRESS <subaddress> Description: Subaddressing can be useful to provide a unique

ISDN address for each profile of the ‘RS-232’ port. This optional command allows an ISDN subaddress to be configured for the ‘RS-232’ port, the subaddress applies to the current profile. If you need subaddressing, check with your ISDN provider to make sure it is available.

Warning: The SET RS232 DN and SET SUBADDRESS commands apply only to the last profile selected. Select a profile before assigning ISDN addresses.

Example: SET SUBADDRESS 1

Sets the subaddress for the RS-232 port (current profile) to 1. See also: SET DN, SET RS232 DN

SET TIME Type: General configuration Syntax: SET TIME <hh>:<mm>:<ss> Description: This command sets the time of day within the

WEBGLIDER. If accurate logging of calls is required the time must be set after the device is powers up, otherwise time defaults to 00:00:00 (midnight). hh, mm and ss represent hours, minutes and seconds of the current time in 24-hour format.
