Operating at V.34 DTE Rates
To operate V.34 or V.34-SDC modems at DTE rates greater than 19.2 kbps, you must
use cables that can handle the higher data rates. Refer to Appendix B for instructions
on determining the correct cables to use.
Ferrite Cylinders
Ferrite cylinders or beads installed on cables filter out line disturbances. They are required on
some 326X models in some countries, as described in this section.
Caution
Install cables with the ferrite end adjacent to the modem. The ferrite
cylinder ensures that the unit operates in compliance with FCC RFI
requirements.
Models 3261 and 3266 – Dial Line Connections
Two telephone cables with ferrite cylinders are included in the Model 3261 (U.S.A.) and the 3266
(Canada, Germany, U.K., and Japan) accessory kit. Connect the cables from the modem to 6- or 8-
conductor dial-line connections.
Install the telephone cable. Figure 2-4 shows the proper orientation. Figure 2-8, in the next section,
shows how to connect the 3261/3266 modem.
