POTS settings in the Module menu determine how your codec will connect at a particular site. You can copy similar programs between codecs installed at different locations and also configure site-specific settings for how each module should connect. The default Config settings for POTS modules are designed to suit Tieline codecs. These settings will need to be adjusted to connect to non-Tieline POTS codecs or connect in Analog Phone mode.

 

Configuring POTS G5 Modules

1.Open the Java Toolbox Web-GUI and click the Settings Configure panel symbol symbol at the top of the screen to display the Settings panel.

 

2.Click the Modules button at the top of the Settings panel.

 

3. Select Module 1 or Module 2.

 

Settings - Modules - select POTS module

4.Click the drop down arrow to adjust the Answer Mode and select how the module in the codec will be able to answer incoming POTS calls. Options include:

 

•POTS Codec: allows the POTS G5 module to receive incoming audio data over a POTS line.

•Analog Phone: configures the POTS G5 module to receive a standard analog phone call.

•Disabled: disables the POTS G5 module from receiving a POTS Codec or Analog Phone call.

 

Settings - Modules - Answer Mode

 

Calls are answered based on the POTS Answer settings in Config 1 & 2. Adjustments to these Config settings are not normally necessary when connecting between Tieline codecs. They are normally adjusted when connecting to non-Tieline codecs over POTS (see Configuring POTS Answering for more info).

 

5.Click the Max Bitrate drop-down arrow to adjust the maximum bit rate (dialing and answering). The default setting is 28800 (28.8kbps) and this only affects POTS Codec calls. The range of the setting is 9.6kbps to 33.6kbps. Even if the line is capable of establishing a connection at a higher bit rate, the Max Bitrate setting is the highest bit rate that will be attempted. Reducing this value can improve connection reliability on poor quality lines. If two codecs are not configured the same, they will attempt to connect at the lowest of the two Max Bit rate settings.

 

Settings - Modules - Max Bitrate

Important Note: G5 POTS modems initially attempt to establish a link at the lowest Max Bitrate setting configured in the two modules being connected. If the POTS line doesn't support this bit rate, the modems will attempt to connect at the highest possible bit rate to suit the prevailing line quality at each end of the link.

 

Dialing Method (Dialing only)

Click the drop-down arrow for Dialing Method to select Tone (DTMF) or Pulse dialing over POTS Codec connections. Tone dialing is used always when the Answer Mode is Analog Phone.

 

Settings - Modules - Dialing Method

Dial Tone Detect (Dialing only)

Click the drop-down arrow for Dial Tone detect to select either:

 

•Dial Tone Detect: The module will only be allowed to dial when a dial tone is present on the line.

•Blind Dialing: Allows the module to dial when no dial tone is present.

 

Settings - Modules - Dial Tone Detect

Monitor Modem Tone (Dialing and Answering)

Click the drop-down arrow for Monitor Modem Tone to select either Enabled or Disabled.

 

Settings - Modules - Monitor Modem Tone

When enabled the module will allow audio monitoring of modem tones during connection in POTS Codec mode via the phone input. By default, the following phone input monitoring rules apply when multiple POTS G5 modules are installed in a codec and multiple POTS connections are dialed.

 

Module 1

Module 2

Audio Rule

POTS Codec

(Monitor Modem Tone)

POTS Codec

(Monitor Modem Tone)

The phone input receives a mix of modem tone audio from both modules

POTS Codec

(Monitor Modem Tone)

Analog Phone

The phone input receives analog phone input audio only and mutes modem tone monitoring

Analog Phone

Analog Phone

The phone input receives audio from the oldest active connection only

 

information2

Important Notes:

•Modem tone monitoring will work even if Phone Input Enable is Off via Settings > Audio > Phone Input > Phone Input Enable [Off].

•Modem tone monitoring is only enabled during the initial connection training and negotiation period in POTS Codec mode.

•The monitoring volume can be adjusted using the codec front panel via Settings > Audio > Phone Input > Level, or by opening the Inputs panel in the Web-GUI and adjusting the Phone input volume slider.

 

Country

This displays the current country setting in the codec. To adjust this setting select Settings > System > Country.
