Configuring Dsp Templates - AudioCodes Mediant 1000 User Manual

Note:
•
For ground-start signaling, make sure that the device's chassis houses the FXO G
module (and not the regular FXO module).
•
To support FXO ground-start signaling, set the following additional parameters:
√
EnableCurrentDisconnect to 1
√
FXOBetweenRingTime to 300
•
The FXS ground-start interface does not generate a ringing voltage; the FXS
interface initiates the signaling by grounding the TIP lead.
The following procedure describes how to configure the Port Ground Start table through
the Web interface. You can also configure it through ini file (GroundKeyDetection_x).

To configure signaling method per port:
1. Open the Port Ground Start table (Configuration tab > VoIP menu > Media > Port
Ground Start Table).
2. For each port, select one of the following from the Ground Start drop-down list:
•
[0] Disable = (Default) Port uses loop-start signaling.
•
[1] Enable = Port uses ground-start signaling.
3. Click Apply, and then reset the device with a save-to-flash for your settings to take
effect.

Configuring DSP Templates

The DSP Template determines the coders that can be used by the device and various
other functionalities. For a list of DSP templates and the maximum number of channels
supported by each coder, see ''Channel Capacity'' on page 1187. You can select a single
DSP Template.
Note: If you do not configure a DSP template, the device uses the default DSP
template (i.e., Template 0).
The following procedure describes how to configure a DSP template through the Web
interface. You can also configure it through ini file (DSPVersionTemplateNumber) or CLI
(configure voip > media settings > DSP-version-template-number).
