Release 3 enhancements

Full Duplex Handsfree capability

The Full Duplex Handsfree (FDHF) functionality allows simultaneous,
two-way communications during a handsfree call. For Full Duplex
Handsfree functionality, you require an M3904 Release 3 telephone set
equipped with an FDHF cartridge accessory. For hardware requirements
information, see
The set attenuates the receive audio level during FDHF mode while both
parties are speaking. Therefore, there can be fluctuations in the receive
volume during an FDHF call. During the call, you can insert or remove the
FDHF cartridge from the Accessory Connection Module (ACM) without
interrupting the established call. If you remove the FDHF cartridge, the
set restores half duplex operation.

Pause in Dialing Strings

This feature enables the user to enter a 1.5-second delay in the dialing
sequence on an external line. The sets use the delay for applications such
as answering machines, IVR systems, auto attendant, when programming
or editing their Personal Directory or Redial List. A new soft key, labeled
"Pause", appears on the M3903, M3904, and M3905 telephone sets.
This feature introduces a Pause soft key. To enter a Pause in the dialing
string while editing a number, press the Pause soft key. A Pause place
marker appears in the dialing string.
The pause character is two parallel bars (||) that appear in the dialing
display. You can insert additional pauses (for example, four pauses = 4 x
1.5 sec. = 6-sec. delay.) This feature is supported when using the Release
3 PC utility, NTMN82AB or later.

The user can press the Directory/Log key and start a directory search
through the dial pad without pressing the Select soft key. Searches
can now be made with three letters, rather than only one.
Instead of needing two key strokes with Corporate Directory, the user
presses the Applications keys and enters letters using the dial pad to
begin a search.
Call Log and Redial List can be datafilled as either context-sensitive
soft keys or programmable feature keys.
