Product Features

V. 9 2 Te c hn ol og y

The V.92 standard is an exciting advancement in 56K technology. V.92 offers three functions to enhance the current V.90 standard.

The first enhancement is the “V.PCM-Upstream” technology, which allows a modem's upstream communication to reach speeds of 48,000 bps. The V.90 standard limited upstream speeds to 31,200 bps.

The second enhancement is Quick Connect, which permits quicker dial-up connections by allowing the modem to remember the line conditions of a service provider that supports V.92. The first time that you connect with your service provider, the modem will perform the full training sequence and store the information it receives. This eliminates the need for the modem to go through the full training sequence during subsequent connection attempts reducing the connection time by 30 - 50%. If the modem is unable to make an optimal connection any time after the initial attempt, the modem will perform the full training sequence.

The third enhancement is the “Modem On Hold” technology, which allows your Internet connection to be suspended when there is an inbound telephone call. You can then return to the connection when the call is completed without losing the connection. If you are connecting to a service provider that supports V.92, you will receive a message informing you of an incoming call.*† In addition, if you subscribe to Caller ID service, the number of the incoming call will be displayed in the computer's message window. You will then have the option to accept the call or to ignore it. If you are connecting to a V.92 server and choose to accept the call, another message will appear notifying you of the length of time that the provider's system will wait on hold before the data connection is terminated. If you are connecting to a server that does not support V.92, you will receive a message informing you of an incoming call. You will then have the option to accept the call or to ignore it. If you choose to accept the call, your data connection will be terminated.

Included on the Installation CD-ROM is the Instant Update software. The Instant Update software automatically notifies you of any updates to your modem's code.

Contact your service provider to find out when your ISP will offer V.92 technology. This modem is backward compatible and will negotiate the highest

possible speed when connecting to a service provider.

* You must subscribe to Call Waiting service with your phone company in order to use the “Modem On Hold” enhancement. † If your incoming calls immediately forward to voice mail, you will not receive this message.

V. Everything Technology

The modem supports all key ITU analogue communications protocols and many proprietary ones to provide you with ultimate compatibility. The modem also supports V.25bis synchronous mode using bisync and HDLC protocols and 2wire leased line operations for compatibility with many legacy systems.

V. Everywhere Technology

The V.Everywhere technology in this modem allows this modem hardware and firmware to be used anywhere in the world. A simple setup to configure the modem for the country of operation is all that is required.

Remote Flash

You can easily upgrade your modems in the field from the convenience of your local office by enabling the remote “flash” capability of the modem. See the “Up grading” chap ter of the Com mand Reference inc luded on the Installati on CDROM.

Dial and Dialback Security

The modem provides you with a robust mechanism for providing dial and dialback security for your network. See the “Dial Security” chapter of the Command Reference included in the Installation CD-ROM.

Remote Manageability

The modem can be remotely configured and monitored for the convenience of your local office. See the “Accessing and Configuring Remotely” chapter of the Command Reference included in the Installation CD-ROM.

Troubleshooting

Having trouble with your modem? Try these basic troubleshooting steps first!

1. Is your modem turned on? When your modem is properly connected to an electrical outlet, a wall outlet, or a surge protector and is turned on, the CTS and MR lights on the front panel will be illuminated.

2. Is your power supply connected properly to both your modem and an electrical outlet? If it is, check the outlet with another electric device (like a lamp) to be sure that you are getting power. Also, use the power supply that came with your modem; other similar-looking power supplies may be of different voltages and could damage your modem.

3. Are you using the proper cable to connect your modem to your computer? Make sure you are using an RS-232 modem cable, preferably the one that came with your modem. There are many computer cables that look similar to an RS-232 that will not work correctly with this modem. For example, a Null Modem cable will not work with your modem. Depending on whether

you have a 9-pin or 25-pin serial port on your computer, you will need either a DB9/DB25 or a DB25/DB25 serial cable.

4. For standard usage, make sure the DIP switches on the bottom of your modem are set correctly. DIP switches 3, 5, 8, and 9 should be in the on (down) position. See the diagram in the DIP Switch section in this manual for the proper settings.

5. Is your phone cord properly connected? The phone cord should be plugged

into the jack on the modem and into the telephone wall jack. Use the phone cord included in your modem’s box, if possible.

If you have any difficulty with your modem, first make sure that it was installed correctly.

came with your modem. Other similar-looking power supplies may be of different voltages, and in addition to possibly causing damage to the modem, they may not allow the modem to dial out.

Possible Solution: Your phone cord may not be plugged in or may be plugged into the wrong jack on the modem.

Possible Solution: Make sure the other end of the phone cord is plugged into a working analogue phone jack in your home or office.

Possible Solution: You may have devices between the modem and wall jack that affect the quality of your phone line. If you need to connect other devices to your phone line and want to ensure the best quality line for your modem, connect the phone cord directly from the wall to your modem.

Possible Solution: Make sure the phone line you are using is not a digital

line. Digital phone lines can damage your modem. If you are unsure which type of line you are using, you may want to call your local phone company. In an office environment, you may need to contact the person in charge of your phone system to find out which type of phone line you have.

Possible Solution: If your phone system requires dialing a digit such as “9” in order to access an outside line, be sure to add the digit and a comma (9,) before the number you want to dial.

Possible Solution: If yo u h ave voi ce ma il pr ov ided by yo ur phon e co mp any, your dial tone may be altered when messages are waiting. Retrieve your voice mail to restore a normal dial tone. If you are unable to retrieve the messages, you may want to add five commas to the beginning of the number to be dialed.

NOTE: Each comma represents two seconds. Therefore, adding five commas will delay the modem connection attempt by 10 seconds. Since each ISP connection may vary, you should insert as many commas as necessary to meet your specific needs. Commas may be necessary if voice mail messages have not been deleted before attempting to establish an Internet connection.

Possible Solution: Be sure you have the correct country code selected for your modem. See the “Configuring V.Everything” section of this guide for instructions.

Possible Solution: You may have a bad phone cord connection to the modem. Try the modem with a different phone cord. We recommend that you use the phone cord included with the modem, if possible.

How to Check for a Non-standard Dial Tone

1. Open a terminal program, such as HyperTerminal, in Windows.

2. Select Cancel at the new connection dialogue box to open the Terminal window.

3. Type AT and press ENTER. You may not see the letters, which is fine.

4. The modem should respond with an OK message. If you did not see the letters A and T as you typed them, type ATE1 and press ENTER. You should now see the AT commands as you type them, in addition to the responses.

5. Type ATDT and press ENTER.

6. If the modem comes back with a No Dial Tone message, type the phone number of a local ISP (Internet Service Provider) or BBS number and press ENTER.

NOTE: The number in the command code is the actual number to be dialed.

7. If the modem dials out instead of coming back with a No Dial Tone message, you have a non-standard dial tone. At this point you should either have your phone line checked or try adding X3 to the Extra Settings field. Access Extra Settings for help locating the Extra Settings field specific to your operating system.

8. If the modem doesn't attempt to connect and it comes back with a No Carrier message, the issue may not be phone line related.

My modem won’t dial out or doesn’t answer incoming calls.

Possible solution: Make sure that you are using the power supply that

came with your modem; other similar-looking power supplies may be of different voltages and could damage your modem.

Possible solution: You might have a bad phone cord connected to your modem, or your phone cord may be plugged into the wrong jack. The phone

cord should be plugged into the jack labelled on the modem and into the telephone wall jack. Use the phone cord included in your modem’s box, if possible.

Possible solution: You may have devices between the modem and the phone jack. There should be no line splitters, fax machines, or other devices between the modem and the telephone wall jack.

Office Users

Possible solution: You may have plugged your modem’s phone cord into a digital line, which can damage your modem. Contact your phone system administrator if you are unsure whether or not your phone line is digital. If your phone system requires dialing “9” to access an outside line, be sure to add “9” before the number you are dialing.

Dialing Problems for Voice Mail Users

Possible solution: If you have voice mail provided by your local phone company, your dial tone may be altered when messages are waiting.

Retrieve your voice mail to restore your normal dial tone.

My modem sounds like it’s trying to connect to another modem but fails.

Possible solution: You may have a poor connection. All calls are routed

differently, so try placing the call again. Possible solution: Make sure that the DIP switches on the bottom of your modem are set correctly. DIP switches 3, 5, 8, and 9 should be in the ON (down) position. See the diagram in the “Configuring the Courier 56K Business Modem with DIP Switches” section in this guide for the correct settings.

My modem isn’t achieving a 56K Internet connection.

Possible solution: Our research has shown that the vast majority of

telephone lines can and do support V.90/V.92 connections. The V.90/V.92 protocol allows for connection speeds of up to 56K, but line conditions may affect the actual speeds during a given connection. Due to unusual telephone line configurations, some users will not be able to take full advantage of V.90/V.92 technology at this time. In order to achieve a V.90/ V.92 connection:

1. The server you are dialing into must support and provide a digital V.90/ V.92 signal. Your ISP can provide you with a list of dial-up connections and information on what those connections currently support.

2. The telephone line between your ISP and your modem must be capable of supporting a 56K connection and contain only one analog-to-digital conversion. The 56K signal from your ISP begins as a digital signal. Somewhere between the ISP and your modem, there will be a digital-toanalogue signal conversion so that your modem can receive the data. There must be no more than one analog-to-digital signal conversion in the path from your ISP to your modem. If more than one analog-to-digital conversion occurs, your connection speeds will default to V.34+ (33.6 Kbps). There may also be impairments on the local lines between your ISP and your modem. These impairments can prevent or limit connection speeds. All telephone calls are routed differently, so you should try making your 56K connection several times. One way to test this is to dial into a long distance location. Long distance lines are often much clearer than local lines. It is important to note that telephone companies are constantly upgrading their systems. Lines that do not support 56K today may support 56K in the near future.

3. For a V.90 connection, your modem must be connecting to a V.90/56K server. A pair of 56K modems will not connect to each other at V.90/56K speeds.

4. For a V.92 connection, your modem must be connecting to a V.92 server. A pair of 56K modems will not connect to each other at V.92/56K speeds.

Caractéristiques du produit

Technologie V.92

La norme V.92 est une amélioration de la technologie 56K. Elle offre trois fonctions qui s'ajoutent à celles de la norme V.90 actuelle.

La première de ces améliorations est la technologie « V.PCM-Upstream », qui permet au modem d'émettre des données à des vitesses atteignant 48 000 bits/s. Avec la norme V.90, cette vitesse était limitée à 31 200 bits/s.

La seconde amélioration est la fonction « Quick Connect », qui permet de se connecter plus rapidement. Le modem mémorise l'état de la ligne du fournisseur d'accès prenant en charge la norme V.92. La première fois que vous vous connectez à votre FAI, le modem effectue toute la phase de négociation et stocke les informations qu'il reçoit. Ainsi, il n'a plus besoin de passer par cette phase pour les connexions ultérieures, ce qui réduit le délai de connexion de 30 à 50 %. Si le modem ne parvient pas à établir la connexion optimale après la première tentative, il effectue toute la phase de négociation.

La troisième et dernière amélioration est la technologie « Modem On Hold », qui permet de suspendre la connexion Internet lorsque vous recevez un appel téléphonique. Vous pouvez reprendre votre session en ligne après l'appel sans perdre la connexion. Si vous vous connectez à un fournisseur d'accès prenant en charge la norme V.92, vous recevrez un message vous indiquant que vous recevez un appel.*† De plus, vous pouvez vous abonner au service Présentation du numéro, qui affichera le numéro de l'appelant dans la fenêtre de messages de votre ordinateur. Vous pouvez alors choisir de prendre ou non l'appel. Si vous vous connectez à un serveur V.92 et que vous décidez de prendre l'appel, un autre message s'affichera pour vous informer de la durée d'attente que le système du fournisseur vous accordera avant de mettre fin à la connexion de données. Si vous vous connectez à un serveur ne prenant pas en charge la norme V.92, vous recevrez un message vous indiquant que vous recevez un appel. Vous pouvez alors choisir de prendre ou non l'appel. Si vous choisissez d'accepter l'appel, la connexion de données sera perdue.

Lorsque vous êtes en ligne, le logiciel de mise à jour instantanée U.S. Robotics Instant Update permet au modem de vérifier automatiquement quelle est la version du code la plus récente.
