The Zoom/FaxModem 56K Dualmode models are high-speed V.90 faxmodems with voicemail that have the ability to receive data from compatible sites at speeds up to 56,000 bps, and at higher speeds with compression. They incorporate both V.90 and K56Flex to achieve download speeds nearly twice as fast as any conventional analog modem. A full duplex sound card is required to setup the voice mail features.

You can determine if your modem has a Lucent chipset or a Rockwell chipset by the serial number of your modem. An "L" in your modem's serial number indicates that you have a Lucent chipset. The absence of an "L" indicates that you have a Rockwell chipset. The modem's serial number is located on the bottom of external models under the barcode and on the back bracket of internal modems (near the phone jacks).

"n" is any integer from 0-9 in the following examples:
nnnn-Z2949-nn-nnL-nnnn uses a Lucent chipset.
nnnn-Z2949-nn-nn-nnnn uses a Rockwell chipset.

These chipsets differ in manufacturer only and offer the same functionality. Please note the presence or absence of an "L" in the below model #'s when selecting files for your modem. Files listed on this page for use with our Rockwell chipset products will not work with our Lucent chipset products.
