Matrix ETERNITY NE System Manual 231
When you reduce the Fax Packet Period, the fax image will be sent at lower speed. EQM is inversely
proportional to Fax Packet Period.
Do not change the default settings unless it is required.
3. Set the Image Redundancy Level to the desired value. The Fax Image Level is redundancy level for
output Image, which can be from 0 to 3. Default: 1.
Fax Image transfer speed is inversely proportional to this parameter. If this parameter is low then fax is
transferred faster. EQM is directly proportional to this parameter. If this parameter is high, good quality fax
can be achieved.
You may increase the Fax Image Level from 1 to 3 if the quality of fax does not improve with Fax Max Rate
and Fax Packet Period.
Level 0 means no redundancy.
4. Set the Data Redundancy Level to the desired value. Default: 3. This is a redundancy level for T.30
control data. Fax Data Level can be set from 0 to 7. Level 0 means no redundancy. Redundancy level
increases from 1 towards 7. The higher the level set, the slower would be the fax transmission.
EQM is directly proportional to this parameter. The higher the Fax Data Redundancy Level, the better the
EQM.
Gain Settings
• To increase the level of incoming speech volume of calls from this SIP trunk to Mobile trunks/DKP
extensions, set the Rx Gain for SIP to Digital Trunk/DKP Voice call (dB) to the desired level from -31 to
31dB. Default:0.
• To increase the level of outgoing speech volume of calls from this SIP trunk to Mobile trunks/DKP
extensions, set the Tx Gain for SIP to Digital Trunk/DKP Voice call (dB) to the desired level from -31 to
31 dB. Default: 0.
• You can also set the Rx and Tx Gains for SIP to Analog Trunks and Extensions (CO and SLT).
• To increase Rx and Tx Gain for SIP to CO trunks, go to the "CO Trunks” page of Basic Settings.
• To increase Rx and Tx Gain for SIP to SLT extensions, go to “SLT” parameters page of Basic Settings.
