Program 0901 - Basic Trunk Port Setup (Part A), Item 23:
Unsupervised Conference Call CODEC Gain Type
Conference calls may experience an echo. To prevent this, the conference gain settings have been changed for VoIP
trunks. If there is a VoIP trunk on a conference circuit, the gain setting will be changed for the conference member who is
on a trunk or single line telephone. In these cases, the gain setting in this program will be used for those conference mem-
bers. If there are two VoIP trunks in the conference, the gain setting from either port will be chosen by the system. The
value of the gain should be lower than 0 dB, otherwise an echo will occur.
Refer to
Program 0154
for information on DSP gain settings.
Range:
Type 1: 1 (0 dB transmit and receive gain)
Type 2: 42 (-5 dB transmit and receive gain)
Type 3: 38 (-3 dB transmit and receive gain)
Type 4: 6 (+3 dB transmit and receive gain)
Type 5: 10 (+5 dB transmit and receive gain)
Default: Type 2 setting 42 (-5 dB transmit and receive gain)

This program is used by the F-Route or ARS feature. When not using Gatekeeper, set the IP address and trunk groups.
For an IP address, please ask your MIS network administrator.
Table Number: 1 – 96
VoIP Trunk group number: 0 – Trunk group MAX (26)
IP Address: xxx.xxx.xxx.xxx (xxx: 0 – 255)
Default: All entries are set to ‘0
’
.

Firmware Upgrade
The VoIP PCB provides a PCMCIA card slot for firmware upgrades. This slot can only accept an
ATA
PC card.
It should be noted that
this card is NOT the same PC card used to update telephone system software.
Using the following steps will allow you to use the ATA
PC card to update the firmware of the VoIP PCB.
1.
Remove the VoIP PCB from the system cabinet.
The system should remain powered up. If it has been powered down, wait until the system completely reboots or the VoIP PCB
firmware update will not be completed.
2.
Insert the PCMCIA card containing the firmware update into the PCMCIA card slot on the PCB.
3.
Press and hold the red load switch located on the VoIP PCB and insert the PCB back into the system cabinet.
4.
Continue holding in the load switch until the PLT and LED1 LEDs are lit on the VoIP PCB.
The system starts the firmware update. LEDs on the PCB will start to light from the highest port to the lowest (8, 7, 6, etc.).
5.
Once all LEDs except the CDLED are off, the updating process is complete.
The PCB will reboot automatically.
6.
Remove the PCMCIA card from the PCB.
The CDLED will go out.
