DISCUSSION

    Question 1: Can I purchase a stand-alone internal Ethernet/modem card?

    Answer : The combination Ethernet/modem card included in most PowerBook 3400 and G3 series computer configurations in US and Canada (and in all configurations sold in Japan) is produced for Apple using Apple specifications. Apple is responsible for all service and support for these configurations.

    If US or Canadian customers purchase a PowerBook 3400 or G3 series computer without the internal Ethernet/modem card included, Apple does not supply this card as a stand-alone item for later purchase.

    Question 2: Do I have to use the dongle even if I'm not using Ethernet?

    Answer : You do not need to use the Ethernet/modem adapter (dongle), which is supplied with your computer, if you are using only one function at a time. Either a modem cord or a 10BaseT Ethernet cord can be plugged into the single port on the back panel of the computer. The port will recognize the type of cable that is plugged into it and it will act accordingly. The adapter is only needed if you want both Ethernet and modem at the same time.

    Question 3: Tell me about the phone cord supplied with the computer for this pre-installed, internal modem. Do I have to use this one? Can I not use just a regular phone cord like I have at my house? What will happen if I use a four-wire cord?

    Answer : The phone cord supplied is a two-wire (single-line) phone cord in which only the center two pins are connected. The cord has a label on it instructing you to use only a two-wire (single-line cord) for the internal modem. If you lose or break the cord it should be replaced with a two-wire cord (available at most electronic stores).

    If you use a four-wire phone cord, in most cases, it will work just fine. However, it is recommended that you use the two-wire cord because, if the telephone outlet plug to which you connect the cord carries two phone lines, including a second phone line over the outer pins of the RJ-11, the second phone line will be connected to the Ethernet circuit.

    Although this should cause no permanent damage, the second phone line will be taken "off hook" and may cease to function properly while the phone cord is plugged into the computer. If when you plug in your modem your other phone line stops working, check to make sure you are using a two-wire (single-line) phone cord.

    A four-wire phone cord should work fine with the Ethernet/modem adapter (dongle). The dongle only has two pins which hook up to the wires on the phone jack. A four-wire phone cord will not take the second line "off hook", but you cannot access the second line from your PowerBook 3400 series computer if you use this type of cord.

    Question 4: Does the internal modem support cellular communications?

    Answer : The internal modem card does not support cellular communications.

    Question 5: Which modem script should I select in Open Transport PPP or America Online?

    Answer : Whether Open Transport PPP, America Online, or any other communication software,first check to see if the software has a selection for either "PowerBook 3400 Internal 33.6" or the "PowerBook 3400/G3 Internal Modem". If neither of these scripts are available in the communication software you are using, see if it has a "Hayes Basic" choice. If not, you will need to contact the vendor of the communications software package. The initialization string for this modem is AT&F.
