Codec Priority: EUT can support different audio Codec (G711u, G711a, G723,

G729a) but only one is active at one time. You can choose “Preferred

Codec”, ”Secondary Codec”, ”Thirdly Codec” and ”Fourth Codec” properly.

FXS: It is used to set many FXS-related options.

Fax Support: The system supports FAX/modem tone detection with G.711 mode.

Call ID Method: The system provides the ability to detect the calling party

identification provided by PSTN lines. It also transmits the calling party identification

to POTS ports. There are four choices: NONE, DTMF_BR, DTMF_AR, FSK

Input Volume Gain: value range: -20 ~ 20. If the value increased 1, the actual

analog-voice will become louder 0.5dB. Otherwise the voice will become lower 0.5dB.

Output Volume Gain: value range: -20 ~ 20.

Inter-digit Timeout: Its range is from 0 to 30 seconds.

FXO: It is used to set many central office line options.

Input Volume Gain: value range: -20 ~ 20

Output Volume Gain: value range: -20 ~ 20

Call Abandon Time: For every PSTN/FXO call, system provides the facility to

monitor the call status. If the remote party hangs up, the ongoing call must be

terminated. The PSTN line monitor is done by the loop-break signal or busy tone.

The value range is: 100/200/…/1000 ms.

Ring Recognition Time: The timer determines the minimum ring duration

recognized as a valid incoming ring on a PSTN port. Shorter ring signals are ignored.

The timer range is 200ms to 60ms in 40ms increments.

Delay Ring Time: The timer is to allow the Central Office to send ICLID before the

call is answered. Once the timer expires, the programmed extensions will ring and

the ICLID number will be sent to the ringing extensions. The timer range is 3 to 6

seconds on 0.5 second increments.

6.6.3.4 IG Dynamic Discovery

This page allows you to configure IG dynamic discovery settings.(Figure 6-37)

IG Name: The name of IG. It will be referred for the other IGs.

Run Mode: The mode that IG is running. IG can run in Master Mode or Slave Mode.

Master Mode: When IG is running in master mode, it maintains an IG list table.

When the master found that some slave IG changes its name or IP address, it will

broadcast to all of other slave IGs in this list and let them update their own IG list

table.

Slave Mode: When IG is running in slave mode, the master IG IP address should be

configured. When its name or IP address changed, it will inform the master IG. And

then the master IG will let other IG know this change.
