You can enter names and numbers into a Personal Directory file on your
Personal Computer (PC). You can download (program) the PC file directly to
the M3904 and M3905 telephones. You can upload (read) a directory from
the M3904 and M3905 telephones to your PC to modify the directory.
An RS-232C cable is required to connect the PC to the Personal Directory PC
Utility Interface Cartridge. The cartridge connects to the M3900 Series
Digital Telephone through the Accessory Connection Module (ACM). The
Personal Directory PC Utility Interface Cartridge is a small cartridge
accessory and can be inserted into either the small or large footstand opening.
The Personal Directory PC Utility Interface Cartridge is powered through the
ACM. The ACM receives power through the telephone via the telephone line
cord which is connected to a Teladapt wall transformer power supply (see
Figure 37 on
page 194 ). Check with your Nortel distributor for the
recommended wall transformer for the M3900 accessories. You must install
the Accessory Connection Module (ACM) into your M3900 Series Digital
Telephone (refer to the ACM Installation Sheet) before you install your
Personal Directory PC Utility Interface Cartridge.
Note: The CTIA Cartridge and the Personal Directory PC Utility
Interface Cartridge are identical. If both products are to be used, only one
cartridge is required.
The Personal Directory PC Utility supports the following languages: English,
French, Spanish, German, Danish, Portuguese, Italian, Norwegian, Swedish,
Finnish, Dutch. The default language is English.
Full Duplex Handsfree
The Full Duplex Handsfree (FDHF) functionality allows simultaneous
two-way communication during a handsfree call. Regular handsfree
operation is half-duplex. Only one party can be heard at a time. FDHF allows
a speaker to be aware when another party on the call is also speaking.
Note: To ensure optimal functionality, the receive audio level is
attenuated during the FDHF mode when both parties are speaking. As a
result, fluctuations in the receive volume can occur during FDHF calls.
If this occurs, do not increase the set speaker volume, as this may cause
the set to revert to half-duplex operation.
