The DSP Jitter Buffer Settings mask is displayed. For descriptions of the individual fields, see
Section 7.7.5.5, "Editing DSP jitter settings".
7.7.5.3 Display All HW Modules
You can display a list of all HW modules available.
WBM path:
WBM > Explorers > Payload > (right-click) HW Modules > Display All HW Modules
The HW Modules mask is displayed. This shows the internal index number, the module type
(current only PDM), and a short description of the module for every HW module available.
7.7.5.4 Editing DSP settings
You can edit the current settings for the DSP modules.
Background information:
See Section 9.5, "Static and Adaptive Jitter Buffer"

The DSP Settings mask is displayed. You can edit the following fields:
General:
Echo Canceller: EC (Echo Cancellation) suppresses the echo effect in voice transmis-
sions. The function is based on G.168. If you do not want to offer this function, deactivate
this option. Normally, EC should always be enabled.
DTMF Outband Signaling: If this option is enabled, DTMF signals are transferred in a sep-
arate signaling channel (outband). If it is disabled, the DTMF signals are transferred in the
normal voice channel.
Fax Parameter:
Error Correction Mode: If this option is activated, errors are corrected during transmission
(ECM mode in the T.30 protocol). The fax machines used must also support this mode.
Number of Redundancy Packets: Select the number of redundant packets set to UDP for
the error correction mode (t38UDPRedundancy). The larger the value, the greater the pro-
tection for fax transmissions against packet losses on the network. Please note, however,
that larger values also increase the bandwidth requirements.
